AB  - In this study, iron oxide nanoparticles immobilized within alginate gel exhibited promising potential for the removal of arsenic (V) ions. The preparation of the polymer-oxide composite  was achieved by the ionic crosslinking of an alginate/iron oxide solution with a calcium (II)ions solution. The maximum amount of arsenic adsorbed by the investigated composite under the experimental conditions was slightly above 26 mg/g in 120 min. The results indicated that arsenic adsorption by this composite material follows a fast kinetic profile, adhering to a pseudo-second-order model. The adsorption process occurs in multiple stages, as suggested by the Weber-Morris model, with external diffusion dominating initially, followed by intraparticle diffusion. Importantly, the results confirmed that the use of alginate gel does not significantly impact the adsorption process, preserving the adsorption capacity of the metal oxides. Overall, the investigated composite successfully removed arsenic (V) from the solution, addressing a critical issue in water treatment.

дице по живи свет. Из тог разлога је потребно развити нове, ефикасне материјале који
у процесу адсорпције могу да уклоне присутне полутанте и реше проблем загађења.
Слојевити двоструки хидроксиди добијени процесом таложења при ниском преза-
сићењу примењени су у процесу уклањања боје метанил-жуто из водених раствора.
Приликом експеримената, варирани су параметри као што су маса адсорбента, време

AB  - Wastewater represents a major environmental pressure on the entire ecosystem.
Pollutants in wastewater, such as dyes, can cause toxic effects on living beings. Therefore, it
is necessary to develop new, efficient sorption materials that can remove the present
pollutants and solve the pollution problem. The layered double hydroxides obtained by the
co-precipitation process at low supersaturation were applied in the process of removing methanil-yellow color from aqueous solutions. During the experiments, parameters such
as adsorbent mass, contact time, and temperature were varied. The obtained results
show a high adsorption capacity of 74 mg g-1 and an endothermic nature during

AB  - Fluorapatite (FAP) crystals have drawn significant interest over the last few decades as important hosts matrix for optically active trivalent rare earth ions, due to the strong crystal field splitting and large transition cross-sections. Nano-sized FAP particles doped with rare earth ions have been extensively studied as luminescent materials for biomedical applications for cell labeling and bioimaging, as well as antimicrobial agents for therapeutics.
Fluorapatite nanoparticles doped with praseodymium ions (Pr3+) were prepared by the co precipitation method and characterized. The different number of Pr3+ (4f2) transitions in the ultraviolet and visible parts of the spectrum was investigated by photoluminescence spectroscopy. Multivariate Curve Resolution–Alternating Least Squares (MCR-ALS) analyses of fluorescence spectra and ab initio calculation indicated that Pr3+ ions are 
preferentially substituted Ca2 (6h) sites in FAP lattice. In addition to the substitution of cations, there is also the substitution of anionic species such as OH-, CO32-, and NO3-, which are confirmed by the CHNS method. The obtained samples were tested as bioimaging and 
antibacterial agents and can potentially be used for further biomedical research.

AB  - Titanium alloys are widely employed in various fields, particularly in biomedical engineering, due to their mechanical  and corrosion resistance properties combined with good biocompatibility. The modulus of elasticity is a distinguishing  feature of this group of materials compared to others used for similar purposes. A database of approximately 238 titanium alloys free of toxic elements was compiled for this study. The influence of different factors (such as alloy element  proportions, density, and specific heat) on the modulus of elasticity was predicted using four methods: support vector machine, XGBoost, Neural Network, and Random Forest. The Random Forest mean absolute error (MAE) of 7.33 GPa, falls within the range of experimentally obtained absolute errors in the literature (up to about 11 GPa). A strong correlation (R2 = 0.72) was observed between experimental and predicted data. Lastly, specific alloying element regions were identified for the modulus of elasticity, which can be used to design new biocompatible titanium alloys in the future.

AB  - The accumulation of mine tailings in the mining area of Majdanpek represents a serious environmental problem. A strong impetus for the development of sustainable methods for the recovery of metals from mine tailings is given by the importance of heavy metal recovery and the economic benefits of precious and base metals. Currently, researchers are working to develop metals recovery from tailings through bioleaching, which is a more sustainable method compared to traditional metallurgical methods. Biotechnologies for leaching heavy metals from old flotation tailings (Majdanpek, Serbia) with fungus Aspergillus niger (A. niger) are discussed in this paper. The subject of this research is iron ions, since the tailings are the richest in this metal. With a simple bioleaching process, which is based on the cultivation of A. niger in the basic growth medium and then challenging it with tailings, 5% iron was released in 35 days. The transformation of mine tailings morphology was also confirmed by optical microscopy. Processes by which A. niger extracts metals from
tailings include acidolysis, complexation, alkaloysis and biosorption. Also, in addition to metabolites, these fungi produce spores and mycelium that can destroy material and transform it to the soil. Given that Serbia is abundant with agricultural
waste, as well as waste from the food industry, in future studies cheap waste should be used as an energy input source for A. niger and transformation of tailings.

материјалне и енергетске ефикасности, посебно на управљање деградације елемената
као што су манган и силицијум. Поред тога, овај приступ ублажава ограничења
рециклирања ефективним смањењем акумулације бакра и калаја у крајњем производу,
чиме се побољшава његов укупни квалитет. На тај начин, не само да се оптимизује
ефикасност процеса, већ се доприноси и смањењу угљеничног отиска индустрије че-
лика, усклађујући се са глобалним тежњама ка декарбонизацији и унапређењу одрживе

AB  - Employing Industry 4.0 and circular economy principles, this study leverages
machine learning in Electric Arc Furnaces steel waste recycling to enhance sustainable steel
production. It focuses on balancing material and energy efficiency, particularly managing
degradation elements like Mn and Si. In addition, the approach mitigates recycling limitations
by effectively reducing the accumulation of Cu and Sn in the end product, thus enhancing its
overall quality. This approach not only optimizes the process efficiency but also contributes
to the reduction of the steel industry's carbon footprint, aligning with global decarbonization
efforts and advancing sustainable manufacturing practices.

AB  - Following the principles of sustainable development and circular economy, an innovative industrial symbiosis approach
has been developed that uses already disposed voluminous waste. The research was focused on the utilization potential
of vast amounts of flotation tailings, fly ash and acidic mine waters. Numerous previous case studies have pointed out the
harmful, long-lasting environmental damage from waste disposal. In this case, the emphasis is on finding a practical
approach for using industrial waste, specifically thermal power plant fly ash, in order to neutralize acidic mine waters
resulting from tailings disposal. The proposed treatment gives waste a practical value, eliminates its harmful effect on the
environment and redefines (lowers) regular waste management costs. In addition, it is possible to obtain valuable metals
by exploiting and reprocessing acidic mine drainage.

Leaching  procedures  are  commonly  utilized  for  the  processing  of  such  mineral  raw materials.As sphalerite is the widespread and most significant mineral of zinc sulfide, a large part  of  the  research  focuses  on  studying  the  behavior  of  sphalerite  in  the  leaching  process.  This paper reviews the existing knowledge about the leaching of sphalerite in acidic solutions as well as the phenomena accompanying the dissolution process. Special attention is given to research related to the kinetics and mechanism of sphalerite oxidation in an acidic medium influenced by various oxidants, such as hydrogen peroxide, oxygen, dichromate ions, nitrate and nitrite ions, ferric and cupric ions, and others. All these results enable the development of  new  technological  procedures  to  produce  zinc  from  low-grade  and  complex  ores  while  meeting increasingly rigorous environmental requirements.

AB  - Titanium alloys have been present for decades as the main components for the production of various orthopedic and dental elements. However, modern times require titanium alloys with a low Young’s modulus, and without the presence of cytotoxic alloying elements. Machine learning was used with aim to analyze biocompatible titanium alloys and predict the composition of Ti alloys with a low Young’s modulus. A database was created using experimental data for alloy composition, Young’s modulus, and mechanical and thermal properties of biocompatible titanium alloys. The Extra Tree Regression model was built to predict the Young’s modulus of titanium alloys. By processing data of 246 alloys, the specific heat was discovered to be the most influential parameter that contributes to the lowering of the Young’s modulus of titanium alloys. Further, the Monte Carlo method was used to predict the composition of future alloys with the desired properties. Simulation results of ten million samples, with predefined conditions for obtaining titanium alloys with a Young’s modulus lower than 70 GPa, show that it is possible to obtain several multicomponent alloys, consisting of five main elements: titanium, zirconium, tin, manganese and niobium.

AB  - Titanium alloys have been present for decades as the main components for the production of various orthopedic and dental elements. However, modern times require  titanium alloys of different composition, with lower modulus of elasticity, without the  presence of toxic alloying elements such as Al and V [1]. Traditional methods used to  detect dependencies between parameters, as well as alloy design, are often not  particularly effective and usually require large investments of time and resources. The study introduces the machine learning technique Extra Tree Regression, which, through  the analysis of data from 246 biocompatible titanium alloys, identifies factors associated with reduced elastic modulus [2]. The three most influential were: specific heat and mass fraction of titanium and mass fraction of titanium silicon. Using data on the most influential factors, four-component diagrams were designed where certain alloy compositions reach a modulus of up to 54 GPa. In addition, Monte Carlo simulations were used to demonstrate the feasibility of modeling multicomponent alloys with elastic modulus below 70 GPa.

AB  - The presence of arsenic in drinking water above the permissible limits is one of the current problems facing modern
engineers in the field of separations and it has not yet been satisfactorily resolved, because the permissible concentrations
of arsenic in drinking water are constantly reduced by the World Health Organization (WHO). Among the various
processes for arsenic removal, adsorption has a special place as one of the most efficient and cheap process. Many natural
and artificial materials are tested for adsorption processes, and adsorption on metal powders is particularly interesting
because they represent adsorbents with fast kinetics and relatively high adsorption capacities. However, the application
of powder adsorbents is difficult due to their separation from the mixture after adsorption. In order to solve that problem,
metal powders may be immobilized into particles obtained by gelling natural polymers. In this way, it is easier to separate
the adsorbent from the mixture, however this must be achieved without losing the adsorption capacity and rate compared
to pure metal powders.
In this study, the use of metal oxide (iron oxide nanoparticles) immobilized within the alginate gel showed good potential
for arsenic (V) ions removal. The obtained results showed that arsenic adsorption by obtained composite has fast kinetic,
following pseudo-second-order model, and that it is conducted in several steps, according to the Weber-Morris model. It
was suggested that external diffusion is the dominant mechanism at the beginning of the arsenic adsorption, followed by
intraparticle diffusion. The obtained results confirmed that gelling with alginate did not significantly affect the adsorption
process, that is, it does not interfere with the adsorption capacity of metal oxides, which is a very important factor. Arsenic
(V) removal was successfully performed using the investigated composite.

AB  - Phytomining although predominantly in its early stages on the broader scientific scope of investigation has garnered
interest in metals such as Ni, Au, Zn or REE. Rare earth elements (REE) are commonly defined as the 15 lanthanides
with the addition of Sc and Y. Since studies of other hyperaccumulating plant species have been conducted before, similar techniques were tried with REE. With the concentration threshold at 0.1 wt% of the dry biomass there have been identified about 22 plant species that hyperaccumulate REE from five families (Phytolaccaceae. Gleicheniaceae, Blechnaceae, Juglandaceae, Thelypteridaceae). One of the most studied REE hyperaccumulators is Dicranopteris linearis (formerly
known as D.dichotoma), a fern native to China that grows on mine tailings. Generally, the techniques for REE
phytomining can be separated into Pyrometallurgy, Hydrometallurgy, Biometallurgy and Novel approaches. Currently most of the research is still focusing on the optimal utilization of various hiperaccumulators and the enchantment of REE extraction from the soil as well as from the enriched biomass. Since recovery of REEs via phytomining is just in its
infancy further multidisciplinary investigations are needed, especially when it comes to valorization and REE recovery.
This paper presents a quick review for the concept of REE phytomining, current state of research, challenges and
prospects.

AB  - Procesi prečišćavanja otpadnih voda, koji su do sada korišćeni, pokazuju ograničenu mogućnost
efikasnog uklanjanja nutrijenata. Ispuštanje netretiranih ili nedovoljno tretiranih otpadnih voda
u recipijente, kao što su reke, jezera i mora, može ugroziti akvatične ekosisteme izazivanjem
procesa eutrofikacije. Stoga je neophodno tretirati otpadne vode, kako sanitarne tako i
industrijske, i ukloniti iz njih štetne materije. U ovom radu je prikazano biološko uklanjanje
azota kao nutrijenta iz otpadnih voda primenom nekonvencionalnih metoda tretmana otpadnih
voda – MBBR (eng. Moving bed biofilm reactor). Biće prikazane njihove modifikacije i prednosti
koje ovakvi procesi nude u odnosu na standardni tretman aktivnim muljem, koji se najčešće
koristi. Prednosti korišćenja MBBR reaktorskih sistema se ogleda u mogućnosti njihove primene
u tretmanu različitih tipova industrijskih otpadnih voda, mogućnosti upotrebe nosača u
konsekutivnim reakcijama prečišćavanja što uzrokuje niže operativne troškove procesa i time ih
čini veoma pogodnim za denitrifikaciju otpadnih voda. Unapređeni procesi biološkog uklanjanja
azota pomoću različitih tipova mikroorganizama biće praćeni sa stanovišta efikasnosti samog

AB  - In oxygen converters, molten iron from the blast furnace is refined with steel waste under oxidizing conditions [1]. The injected oxygen passes into the iron melt, after which it reacts with the impurities. Analysis of exergy losses clearly indicates the place of energy losses in the observed process, so a detailed analysis can influence the improvement of a complex process [2]. Exergy losses occur due to technological imperfections such as heat dissipation or friction and system irreversibility according to the second law of thermodynamics [3]. The concept of exergy can be used for a better understanding of the feasibility of a process, as well as for the techno-economic analysis of the process at different variations of input/operating parameters. In this work througtful calculation of exergy oxygen convertor was done. According to the obtained data, out of a total of 972.2 MJ of thermal energy, which is released by exothermic reactions in the refining process, 817.5 MJ is pure exergy and can be used, the rest is anergy that arises due to irreversibility.

AB  - Releasing untreated or inadequately treated effluents into recipients (rivers, lakes, and oceans) can endanger aquatic
ecosystems and drinking water sources. In order to eliminate harmful pollutants, wastewater must be treated, especially
industrial wastewater enriched with nutrients. Phosphorus contamination can occur through a variety of different routes,
such as wastewater treatment plant discharge (municipal and industrial), agricultural fertilizer losses from erosion,
drainage, etc. The establishment of suitable wastewater treatment techniques is essential. The subject of this paper is the
biological removal of nutrients (phosphorus) from wastewater, using unconventional methods of wastewater treatment -
sequencing batch reactors (SBR) systems. Their modifications and the advantages such processes offer, compared to the
standard activated sludge (AS) treatment that is the most often used, will be presented. Enhanced biological phosphorus
removal methods that employ various microorganisms have been observed from the perspective of the method's
effectiveness. Of all applied treatments for phosphorus removal, the most effective and the most often used was the
accumulation of polyphosphates in the biomass itself. The purpose of this paper is to offer a brief review and theoretical
essentials of environmental engineering techniques that can be applied in real industrial wastewater treatment plants.

AB  - Nickel pollution of water induces several problems for the environment. The purpose of this paper was to
investigate the adsorption of Ni2+ ions on fabricated biomembranes. The proposed adsorbent was prepared
from epoxy and amino-functionalized waste cellulose fibers, able to participate in cross-linking with amino
acid lysine - wCell/Mn-Fe_LDH. The prepared material underwent preliminary structural characterization
by Fourier-transform infrared spectroscopy. In a batch system, the influence of pH, contact time,
temperature, and initial concentration on adsorption efficiency was investigated. The effectiveness of the
membrane was demonstrated by acceptable adsorption capacities of 40.49 mg g-1 obtained for Ni2+ at 45°C.
The kinetic study, using the Weber-Morris model, indicates intraparticle diffusion as the rate limiting step.
Adsorption mechanism physisorption was proposed based on thermodynamic behaviors. The outcomes
demonstrated that environmentally friendly sustainable technology has been successfully developed.

AB  - Aluminothermic welding has been used to connect railway rails for over a century. This technique has the advantages of flexibility, weld compactness, and simplicity. External energy is not required for the procedure. Exothermic heat is produced by chemical reactions of aluminothermic elements. To create a quality welded connection, the mold and pouring system must provide uniform pouring of hot steel
without turbulence, even heat dissipation or cooling, and an acceptable micro and macro structure of steel free of internal and external faults. The design of the mould was constantly changing, necessitating costly industrial experimentation. As a result, the mould's design was constantly evolving, necessitating the use of costly experimental procedures in industrial settings. The latest iteration of the model the
casting cavity was improved by adding hoes in the sand and putting rails on both sides in order to more aquratly simuate heat transfer. Software programs are emulating conventional casting procedures for thermite steel casting in welded railway connections to save money and effort on costly and timeconsuming industrial testing. For the 49E1 rail, NovaFlow & Solid CV were utilized to simulate casting thermite steel in the mould cavity or weld junction.

Iako mnoge metode razvijene za proučavanje mikroplastike nisu direktno primenljive na nanoplastiku, konvencionalne metode karakterizacije nanoplastike su obično zamorne jer proučavaju pojedinačne nanočestice u izolaciji. Pošto nanoplastika koja je rezultat razgradnje mikroplastike ima drugačija svojstva od sintetisanih plastičnih nanočestica, potrebno je razviti nove tehnike koje će nam pomoći da bolje razumemo ozbiljnost problema nanoplastike. Nanoplastika se može izolovati iz vodenog okruženja kombinacijom filtera i ultracentrifugiranja. U novijim publikacijama se navodi da će kombinovanje mikroskopije i spektroskopije, uz podršku hemometrijskih tehnika, omogućiti bolje razumevanje ponašanja čestica nanoplastike u životnoj sredini i organizmima.

AB  - Scientists discovered plastic in the early 1900s, but didn't realize the detrimental effects its fragmentation could have on the environment 100 years later. In particular, nanoplastics (NPs) particles ranging in size from 1 to 100 nm can cause major problems in the living world due to their high specific surface area for the adsorption other polluting substances from water, and their further bioaccumulation through the food chain. There is no distinctive method to identify, characterize, and quantify nanoplastics in aquatic environments. Although many of the methods developed to study microplastics are not directly applicable to nanoplastics, conventional methods of characterizing nanoplastics are usually tedious because they study individual nanoparticles in isolation. Since nanoplastics resulting from the decomposition of microplastics have different properties than engineering plastic nanoparticles, new techniques need to be developed to help us better understand the seriousness of the nanoplastic problem. Nanoplastic can be isolated from the water environment by a combination of filters and ultracentrifugation. A recent publications states that combining microscopy and spectroscopy, supported by chemometric techniques, will alow a better understand he behavior of nanoplastic particles in the environment and organisms. High hopes are placed on microscopies combined with neural networks for the quantification and characterization of nanoplastics in complex systems. This article describes the degradation pathways of plastics and the formation of nanoplastics in aquatic environments, and possible methods for separation and characterization of nanoplastics in relation to recent publications.

A recent publications states that combining microscopy and spectroscopy, supported by chemometric techniques, will alow a better understand he behavior of nanoplastic particles in the environment and organisms. High hopes are placed on microscopies combined with neural networks for the quantification and characterization of nanoplastics in complex systems. This article describes the degradation pathways of plastics and the formation of nanoplastics in aquatic environments, and possible methods for separation and characterization of nanoplastics in relation to recent publications.",

AB  - To increase the degree of cobalt (Co) extraction, the process of the cathode material leaching was performed in a sulfuric acid (H2SO4) solution containing sulfur dioxide (SO2) as a reducing agent. To provide a high resolution of the obtained results, frequent monitoring of Co concentrations in leached solution was conducted using an ultraviolet–visible spectrophotometer with several specific modifications related to the connection of the reaction vessel with the instrumental cuvette. The maximum degree of Co leaching (99.4%) was achieved with H2SO4 concentration of 3 mol/L, solid phase concentration of 33 g/L, temperature of 85 °C, SO2 volume flow of 2 L/min, and leaching time of 60 min. The results of the performed kinetic analyses indicated that the Avrami equation best describes the investigated leaching process, which later was supported by the results of X-ray diffraction and scanning electron microscopy–energy-dispersive X-ray spectroscopy analyses. Also, the activation energy of 28 ± 3 kJ/mol is in favor of the fact that the process of Co leaching was controlled by the factors, such as diffusion and chemical reaction. The results of this study indicated that SO2 can be used as an effective reducing agent in the investigated process.

AB  - In this study, luminescence and antibacterial behavior of pure fluorapatite (FAp) and praseodymium-nitrate-carbonate co-doped fluorapatite (PrNCFAp) nanopowders were investigated. Uniform nanopowders were synthesized by precipitation reaction followed by centrifugation and systematically characterized by XRD, FTIR, SEM-EDS, TG and PL methods. XRD analysis revealed the formation of hexagonal FAp crystals, and FTIR spectra indicate the presence of nitrate (NO3-) and carbonate (CO32-) species. SEM analyzes confirm agglomerates composed of irregular nanometer-sized spheres. Emission of FAp nanopowder occurred in the violet-blue region of the visible part of the spectrum, with redshift to the blue-green color region when Pr3+, NO(3)(- )and CO32- co-doped in the lattice. Analysis of luminescence spectra by MCR-ALS method extract three fluorophores from the PrNCFAp sample and showed simultaneous existents of emission-reabsorption-emission between dopants in FAp lattice. Antibacterial activity against pathogen Staphylococcus aureus was investigated before and after treatment of nanopowders by UVA radiation of 365 nm. Nanopowders irradiated with UVA compared to non-irradiated reduced Staphylococcus aureus by 84.9% for PrNCFAp and 33.3% for FAp in the first 0.5 h of contact, and 76.1% and 42.9% after 24 h of contact. In addition, the obtained luminescent nanomaterials showed a low degree of hemolytic activity and could potentially be candidates for further research in dentistry.

AB  - Environmental management demands innovative techniques for its protection and
treatment. The essential agreement of the modern world is to overcome every issue in a
sustainable way. The two major financial problems in this area are water pollution and
material corrosion. Persistent, organic compounds such as pesticides have devastating effects
on the water ecosystem. This problem can be solved by applying advanced treatment processes
(ATPs) like membrane separation and photocatalysis. Additionally, the corrosion of metal
materials needs to be prevented to preserve natural resources and reduce environmental
concerns. Therefore, researchers are trying to develop tunable, multifunctional materials
with broad applications. Employed materials in these operations must fulfill high criteria, like
durability, stability, and chemical and optical activity, to make specified processes efficient
and viable. Electroconductive polymers (ECPs) can meet the aforementioned standards. The
most used ECP is polyaniline (PANI), due to its catalytic and electrochemical performances.
These two properties are beneficial for both water purification and anticorrosion applications.
The objectives of the paper are to represent various PANI-based composites utilized in the
removal of different classes of pesticides during wastewater treatment by adsorption or
photocatalytic degradation. Further corrosion inhibition, utilizing PANI-based inhibitors, will
be discussed as well.

AB  - Railway rails have been linked using the aluminothermic welding process for over a century. This method has several
advantages, including flexibility, compactness of the weld, and ease of execution. It is not necessary to employ outside
energy to complete the procedure. It is provided by the exothermic effect of the chemical reactions of the aluminothermic combination's elements. The design of the mold with the pouring system, which should ensure even pouring of thermal steel without turbulence, then even heat dissipation or cooling in order to obtain an appropriate micro and macro structure of steel, free of internal and external defects, is an important factor in producing the required quality welded joint. As a result, the mold's design was constantly evolving, necessitating the use of costly experimental procedures in industrial settings. In this iteration of the model the casting cavity was improved by adding hoes in the sand and putting rails on both sides in order to more aquratly simuate heat transfer. Software programs are being used to simulate conventional
casting procedures that can be used in the casting of thermite steel during the fabrication of welded railway connections
in order to prevent costly and time-consuming industrial experimentation. The NovaFlow & Solid CV software package
was used to simulate casting thermite steel in the mold cavity, i.e. in the weld joint, for the 49E1 rail.

AB  - Aluminothermic welding has been used to connect railway rails for over a century. This method has several advantages, including its versatility, the tightness of the weld it creates, and its ease of execution. To complete the procedure, no further power source is necessary. The design of the mold with the pouring system, which should ensure even pouring of thermal steel without turbulence, then even heat dissipation or cooling to obtain an appropriat  micro and acro structure of steel free of internal and external defects, is one of several factors that contribute to a quality welded joint. As a result, costly experimental techniques in industrial settings were necessary to keep up with the ever-changing mould design. The model design was upgraded in comparison to the previous version [1], and will be imroved even further.The two sets of solid steel rails put on either side of the casting mould will be adjusted as heating media within the mould material category in the future, bringing the model closer to reality. As a result, cooling and heating temperatures will be more evenly distributed. Stress and strain modeling were performed to the preheated model to provide a more complete understanding of how shrinkage is related to stress. In future iterations of the model, we will either move the heat source to its right place approximately 40 cm above ground or adjust the temperature, diameter, and gas at the current site to more exactly reproduce real-life circumstances. Furthermore, during simulation setup, the
replace material function may be used to model a new component that represents the divider that will be changed between air and silica sand material at the end of
prehearing. Software programs are being used to simulate conventional casting procedures that may be used in the casting of thermite steel during the fabrication

AB  - Luminescent inorganic nanomaterials (nanophosphorus) based on fluorapatite (FAP) are attracting significant interest for biomedical, biotechnological and environmental applications. 
Luminescent nanopowders based on fluorapatite substituted with Pr3+ and CO32-ions (PrCFAP) were obtained by a simple precipitation method. Previously published results have shown that nanopowders are monophasic and composed of nanospheres, with luminescence in violet color. Also, 
nanopowders exhibit and antibacterial behavior against E. coli. In this study the results of chemocompatibility of antibacterial luminescent nanophospors obtained by precipitation for various biomedical and health applications are presented. Pure FAP showed a degree of hemolysis of 5% and can be considered chemcompatible. Doped nanopowders showed hemolysis up to about 10%. Slight hemolytic behavior of the tested PrCFAP nanopowders may be a consequence of mechanical stress of the cell in the interaction with nanoparticles, as well as the toxic effect of dissolved Pr3+ and 
F- ions from the FAP lattice. The above results indicate that the antibacterial PrCFAP nanophosphorus may be future evaluated for different biomedical applications, such as agents for cells labeling, therapy and drug delivery.
AB  - Luminescentni neorganski nanomaterijali (nanofosfor) na bazi fluorapatita (FAP) privlače značajno interesovanje za biomedicinske, biotehnološke i ekološke primene. Jednostavnom metodom 
precipitacije dobijeni su luminescentni nanomaterijali na bazi fluorapatita supstituisani Pr3+ i CO32- jonima (PrCFAP). Ranije objavljeni rezultati su pokazali da su nanoprahovi monofazni i sastavljeni od nanosfera, sa luminiscencijom u ljubičastoj boji. Pored toga, nanoprahovi su pokazali i antibakterijsko ponašanje protiv E. coli. U ovoj studiji prikazani su rezultati hemokompatibilnosti antibakterijskih luminiscentnih nanofospora dobijenih precipitacijom za različite biomedicinske i zdravstvene primene. Čisti FAP je pokazao stepen hemolize od 5% i može se smatrati hemokompatibilnim. Dopirani nanoprahovi su pokazali hemolizu do oko 10%. Blago hemolitičko ponašanje ispitivanih PrCFAP nanoprahova može biti posledica mehaničkog naprezanja ćelije u interakciji sa nanočesticama, kao i toksičnog dejstva rastvorenih Pr3+ i F jona iz FAP rešetke. Gore navedeni rezultati ukazuju da antibakterijski PrCFAP nanofosfori u budućnosti mogu biti procenjeni za različite biomedicinske primene, kao što su agenti za obeležavanje ćelija, terapije i isporuku lekova.

AB  - Zagađenje vodenih resursa mikro- i nano-plastikom je prepoznato kao globalni problem. Trenutno ne postoje dostupne specifične metode za identifikaciju, karakterizaciju i kvantifikaciju nanoplastike u vodenim sredinama. Mnoge od metodologija razvijenih za analizu mikroplastike ne mogu se direktno primeniti na nanoplastiku, dok konvencionalne
metode karakterizacije nanoplastike obično izoluju i proučavaju pojedinačne nanočestice, što može biti naporan i dugotrajan proces. Korišćenjem mikroskopskih tehnika u kombinaciji sa spektroskopijom, moguće je ubrzati proces analize, ispitati morfologiju i veličinu čestica i istovremeno identifikovati hemiju. Pošto nanoplastika nastala degradacijom mikroplastike
ima drugačija svojstva od sintetisanih nanočestica plastike, neophodno je kreirati nove analitičke i mikroskopske tehnike koje će pomoći da se bolje razume ozbiljnost problema nanoplastike. Ovaj rad ima za cilj da identifikuje metode koje bi mogle da se primene za odvajanje i karakterizaciju nanoplastike iz vodenih sredina.
AB  - Pollution of water resources with micro- and nanoplastics is recognized as a global problem. Currently, there are no specific methods available for the identification, characterization and quantification of nanoplastics in aquatic environments. Many of the methodologies developed for the analysis of microplastics cannot be directly applied to nanoplastics, while conventional nanoplastic characterization methods usually isolate and study individual nanoparticles, which can be a laborious and time-consuming process. By using microscopic techniques combined with spectroscopy, it is possible to speed up the analysis process, examine the morphology and size of the particle and identify the chemistry at the same time. Since nanoplastics created by the degradation of microplastics have
different properties than synthesized plastic nanoparticles, it is necessary to create new analytical and microscopic techniques that will help to better understand the seriousness of the nanoplastics problem. This work aims to identify methods that could be applied for the separation and characterization of nanoplastics from aquatic environments.
