AB  - U ovom istraživanju, ispitivana je sposobnost otpadne biomase kao adsorbenta, pri čemu je ovsena slama (OS) odabrana kao polazna sirovina. Da bi se unapredio kapacitet adsorpcije ovog materijala, on je modifikovan sa odabranim dubokim eutektičkim rastvaračem (DES). Radi proširenja mogućnosti primene nakon tretmana sa DES-om, modifikovana ovsena slama (DOS) je imobilisana u kuglice sa alginatom, te je time dobijen IDOS. Efikasnost adsorpcije teških metalnih jona metala iz rastvora bakra testirana je na modifikovanoj (ili imobilisanoj) ovsenoj slami. Maksimalni dobijeni kapaciteti za adsorpciju jona bakra bili su 26.4, 81.4, 124.78 mg/g respektivno. Dobijeni rezultati pokazali su da adsorpcija prati kinetički model pseudo-drugog reda, što implicira da je hemisorpcija za vezivanje jona bakra, odnosno korak koji kontroliše brzinu adsorpcije.

AB  - Untreated industrial effluent is causing alarming levels of water pollution in our modern world. Hydrochars, functional carbonaceous materials obtained during the hydrothermal carbonization of waste biomass, possess a great potential for use in industrial wastewater treatment. Their high reactivity and regenerative properties compensate its deficiency, which is reflected in a small specific surface area. In addition, these materials are amenable to additional functionalization and modification by various chemical treatments. Previous studies have demonstrated that incorporating metals onto the surface of hydrochar or treating it with hydrogen peroxide or alkalis can significantly enhance its adsorption capabilities. This paper provides a brief overview of using hydrochars from various sources as adsorbents for heavy metals. This review aims to assess the impact of material modification on its structural characteristics and sorption capacity.

AB  - The corrosion behaviour of three types of alloys (two low-alloy carbon steel and one stainless iron with ~15 wt.% Cr), in a solution which simulates seawater (3% NaCl solution, pH 8.1) was tested. Tested samples are used to make steel (iron) balls applied in mils for grinding copper and other ore. The corrosion tests were performed using three electrochemical methods, at room temperature in the presence of atmospheric oxygen. The linear polarization resistance (LPR) method, electrochemical impedance spectroscopy (EIS) method, and linear sweep voltammetry (LSV) method were applied. Based on measurements by LPR and EIS methods (as non-destructive methods), the value of polarization resistance (Rp) was determined and the general corrosion rate (vcorr) of the examined samples was calculated. The obtained values of the general corrosion rate can be used to calculate the service life of steel (iron) balls under exploitation conditions (seawater). The appearance of the surface after linear sweep voltammetry (LSV) measurement showed the presence of localized corrosion (pits were formed) of the tested samples, especially stainless iron, and the LSV method is not suitable for the determination of the general corrosion rate of tested samples in seawater. This form of corrosion occurs at high anodic polarizations, during performing LSV measurements.

AB  - Organobentonites have been applied for the removal of two common non-steroidal anti-inflammatory drugs, ibuprofen (IBU) and diclofenac sodium (DS), from aqueous solutions. Two surfactants, one with and the other without benzyl group (octadecyldimethylbenzylammonium chloride, ODMBA, and hexadecyltrimethylammonium bromide, HDTMA), in amounts equivalent to 50, 75, and 100% of the cation exchange capacity of bentonite were used for the preparation of organobentonites. Successful modification of bentonite was confirmed by several methods: X-ray powder diffraction (XRPD), point of the zero charge (pHPZC), determination of exchanged inorganic cations in bentonite, determination of textural properties, and scanning electron microscopy (SEM). Kinetic and thermodynamic data on the adsorption of IBU and DS showed that drug adsorption was controlled by the type and the amount of surfactant incorporated into the bentonite and by their arrangement in the interlayer space and at the surface of organobentonites. The adsorption of both drugs increased with an increase in the amount of both surfactants in organobentonites. The presence of the benzyl group in organobentonites enhanced the adsorption of IBU and DS and was more pronounced for IBU. Drug adsorption fits the pseudo-second-order kinetic model the best. The thermodynamic data revealed that the adsorption process was endothermic in nature and with increase of the amount of both surfactants drug adsorption processes were more spontaneous. The results obtained from this study revealed that adsorbents based on surfactants modified bentonite are promising candidates for IBU and DS removal from contaminated water.

AB  - INTRODUCTION: Following orthopedic surgery, bacterial infection may lead to significant complications related to
inflammation in the peri-implant region, including the potential for implant loosening. To address this concern, the
surface of metallic implants was modified through the application of bioactive and antibacterial coatings, aiming to
mitigate these issues.
EXPERIMENTAL: HAP/PVA/CS/Gent coatings was single-step electrophoretically deposited from four-component
aqueous suspension containing 1 wt.% hydroxyapatite powder (HAP, particles < 200 nm particle size, Sigma-Aldrich),
0.1 wt.% poly(vinyl alcohol) (PVA, medium molecular weight 89 to 98 kDa, 99 % hydrolysed, Sigma-Aldrich), 0.05 wt%
chitosan powder (CS, medium molecular weight, 190 to 310kDa with 75 to 85 % deacetylation degree, Sigma-Aldrich), and
aqueous gentamicin sulfate solution (Gent, concentration 50 mg/ml, Sigma-Aldrich) on titanium plates (Sigma-Aldrich).
Antibacterial activity of HAP/PVA/CS/Gent coating was evaluated against Staphylococcus aureus TL (culture collection-
FTM, University of Belgrade, Serbia) and Escherichia coli ATCC 25922, while kinetics of antibacterial activity was monitored
according to our previously published data [1]. In vitro cytotoxicity assay was performed towards two fibroblast cell lines
of different origin-mouse origin cell line (L929 (ATCC CRL-6364)) and human lung origin cell line (MRC-5 (ATCC CCL-171)) [2].
To evaluate the statistical significance of the biological assay results (antibacterial activity, cytotoxicity and ALP activity),
one-way analysis of variance (ANOVA) followed by a multiple comparisons posthoc test was used.
RESULTS AND DISCUSSION: HAP/PVA/CS/Gent coating exhibited strong antibacterial effect against both S. aureus
and E. coli, especially pronounced against S. aureus, causing bactericidal effect. Cytotoxic effect of HAP/PVA/CS/Gent
coating was not pronounced in investigated MRC-5 and L929 cell lines. MRC-5 fibroblast cells in contact with
HAP/PVA/CS/Gent doubled alkaline phosphatase levels compared to their contact with the control samples
(HAP/PVA/CS), indicating good osteogenic properties.
CONCLUSIONS: Electrophoretically deposited HAP/PVA/CS/Gent bioceramic coatings on titanium, demonstrated
significant potential as implants in orthopedic practice, functioning as drug carriers. Not only do they possess
antibacterial properties, but they also exhibit no adverse effects on living tissue.

AB  - INTRODUCTION: Tissue engineering strives for innovative solutions in addressing challenges associated with
contemporary bone tissue implants. This study focuses on the electrophoretic deposition (EPD) of hydroxyapatite-based
bioceramic composites containing antibacterial agents onto titanium surfaces. Two composite coatings, hydroxyapatite/
chitosan (HAP/CS) and hydroxyapatite/chitosan/gentamicin (HAP/CS/Gent) were developed to combat issues such as
poor adhesion, limited antibacterial potential, limited bioactivity, and potential toxicity of implant materials [1].
EXPERIMENTAL: EPD was performed at constant voltage (5 V, 12 min) on pure Ti plates from aqueous (HAP/CS and
HAP/CS/Gent) suspensions. The uniformity and functionality of the deposited coatings were assessed through
comprehensive physico-chemical characterization using X-ray diffraction (XRD) (Philips PW 1710, Netherlands) and
scanning electron microscopy (SEM, Hitachi S-4700, J) equipped with energy dispersive X-Ray spectroscopy (EDS, X-Max,
Oxford Instruments, UK). Antibacterial activity was evaluated against Staphylococcus aureus TL and Escherichia coli ATCC
25922 by quantitatively monitoring changes in the viable number of bacterial cells in suspension. Cytotoxicity against
MRC-5 and L929 cell lines was investigated using trypan blue dye-exclusion test (DET) and MTT assay for assessing cell
metabolic activity. Statistical significance was determined for antibacterial and cytotoxicity results by one-way analysis
of variance (ANOVA), followed by multiple comparisons post-hoc test.
RESULTS AND DISCUSSION: XRD revealed broadened diffraction maximums corresponding to fine HAP crystallites.
Porous surface with homogeneously distributed spherical HAP agglomerates embedded in wax-like polymers' matrix of
CS was observed for both coatings by SEM. The addition of gentamicin significantly enhanced the antibacterial activity
of the HAP/CS/Gent coating – complete reduction of S. aureus bacterial cells was achieved within 1 h of exposure. MTT
and DET tests indicated low cytotoxicity against MRC-5 and L929 tested cell line for both samples. Slightly decreased
cell percentage viability due to gentamicin presence was observed for HAP/CS/Gent.
CONCLUSIONS: Single-step EPD yielded antibacterial composite coatings with potential for biomedical applications.
HAP/CS/Gent showed successful gentamicin loading, favorable crystalline structure, and strong antibacterial effects.
The presence of fine HAP crystallites yielded a larger surface area, favorable for new bone growth and improved
osseointegration. HAP/CS/Gent exhibited good antibacterial activity against both tested bacteria (especially
pronounced against S. aureus – bactericidal effect), while preserving low cytotoxicity, indicating the high potential for
biomedical applications.

MRC-5 and L929 cell lines was investigated using trypan blue dye-exclusion test (DET) and MTT assay for assessing cell
metabolic activity. Statistical significance was determined for antibacterial and cytotoxicity results by one-way analysis
of variance (ANOVA), followed by multiple comparisons post-hoc test.
RESULTS AND DISCUSSION: XRD revealed broadened diffraction maximums corresponding to fine HAP crystallites.
Porous surface with homogeneously distributed spherical HAP agglomerates embedded in wax-like polymers' matrix of
CS was observed for both coatings by SEM. The addition of gentamicin significantly enhanced the antibacterial activity
of the HAP/CS/Gent coating – complete reduction of S. aureus bacterial cells was achieved within 1 h of exposure. MTT
and DET tests indicated low cytotoxicity against MRC-5 and L929 tested cell line for both samples. Slightly decreased
cell percentage viability due to gentamicin presence was observed for HAP/CS/Gent.
CONCLUSIONS: Single-step EPD yielded antibacterial composite coatings with potential for biomedical applications.
HAP/CS/Gent showed successful gentamicin loading, favorable crystalline structure, and strong antibacterial effects.
The presence of fine HAP crystallites yielded a larger surface area, favorable for new bone growth and improved
osseointegration. HAP/CS/Gent exhibited good antibacterial activity against both tested bacteria (especially
pronounced against S. aureus – bactericidal effect), while preserving low cytotoxicity, indicating the high potential for
biomedical applications.",

AB  - INTRODUCTION: Owing to its similarity to the inorganic part of the natural bone, excellent bioactivity, biocompatibility,
and ability to stimulate the osteoconductive process, synthetic hydroxyapatite (HAP) is very often the material of
choice for biomedical applications. Diverse ions can be found as substitutes within natural bone structures, each playing
a distinct and crucial role in the physiological processes governing the lifecycle of bones [1]. Among them, strontium ion
has a very important role for the acceleration of osteogenesis and the inhibition of osteoclasts activity [2]. Current
research aims to provide physico-chemical characterization of synthesized HAP and strontium substituted HAP (Sr-HAP)
powders obtained by varying strontium concentration (10, 20 and 40 mol.%) in the starting solutions.
EXPERIMENTAL: HAP powder was synthesized by wet chemical precipitation, using aqueous solutions of Ca(NO3)2
4H2O (Merck, p.a.) and (NH4)2HPO4 (Sigma-Aldrich, ≥99 %). By adding NH4OH (CENTROHEM, p.a.), pH value was adjusted
to 10. The obtained precipitate was heated up to 90 °C. The same procedure was followed for Sr-HAP powder syntheses,
by adding Sr(NO3)2 (Sigma-Aldrich ≥99.0 %) and maintaining the (Ca + Sr)/P ratio at 1.67 in the mixed Ca2+/Sr2+ solution.
Synthesized powders were characterised by FTIR spectroscopy (Nicolet IS-10, Thermo Fisher Scientific), XRD analysis
(Philips PW 1710, Philips, The Netherlands), TG analysis (Netzsch STA 449 F5 Jupiter instrument), and FE-SEM analysis
(JSM-7001F, JEOL Ltd, Japan).
RESULTS AND DISCUSSION: FTIR spectra revealed the presence of carbonate-substituted hydroxyapatite in both pure
and Sr-substituted HAP powders. The powders showed a granular, homogeneous morphology without the Sr separation.
XRD analysis revealed that the amount of incorporated Sr in the HAP structure increased with increased Sr concentration
in the starting solutions. Thermal stability of the Sr-HAP powders decreased with increased Sr concentration.
CONCLUSIONS: Physico-chemical characteristics of Sr-HAP powders are directly dependent on Sr ion concentration
in powders.

AB  - Smelting used to be less efficient; therefore, wastes obtained from historical processing at smelter plants usually contain certain quantities of valuable metals. Upon the extraction of useful metal elements, metallurgical slag can be repurposed as an alternative mineral raw material in the building sector. A case study was conducted, which included an investigation of the physico-chemical, mineralogical, and microstructural properties of Pb–Zn slag found at the historic landfill near the Topilnica Veles smelter in North Macedonia. The slag was sampled using drill holes. The mineralogical and microstructural analysis revealed that Pb–Zn slag is a very complex and inhomogeneous alternative raw material with utilizable levels of metals, specifically Pb (2.3 wt.%), Zn (7.1 wt.%), and Ag (27.5 ppm). Crystalline mineral phases of wurtzite, sphalerite, galena, cerussite, akermanite, wüstite, monticellite, franklinite, and zincite were identified in the analyzed samples. The slag’s matrix consisted of alumino-silicates, amorphous silicates, and mixtures of spinel and silicates. Due to the economic potential of Pb, Zn, and Ag extraction, the first stage of reutilization will be to transform metal concentrates into their collective concentrate, from which the maximum amount of these crucial components can be extracted. This procedure will include combination of gravity concentration and separation techniques. The next step is to assess the Pb–Zn slag’s potential applications in civil engineering, based on its mineralogical and physico-mechanical properties. Alumino-silicates present in Pb–Zn slag, which contain high concentrations of SiO2, Al2O3, CaO, and Fe2O3, are suitable for use in cementitious building composites. The goal of this research is to suggest a solution by which to close the circle of slag’s reutilization in terms of zero waste principles. It is therefore critical to thoroughly investigate the material, the established methods and preparation processes, and the ways of concentrating useful components into commercial products.

AB  - The incombustible portion of coal that remains after burning is known as bottom or fly ash, and it has a detrimental influence on the environment. One of the possible alternatives for reducing the amount of ash deposited in landfills might be the production of useful glass-ceramic from vitrified fly ash. Glass-ceramic was synthesized using fly ash from the thermal power plant "Nikola Tesla" and fluxing additives. Sinter-crystallization of the parent glass resulted in glass ceramics. The glass was created by melting a combination of coal fly ash (CFA), Na2CO3, and CaCO3 at T= 1500 °C and quenching the melt in the air. Glass powders were sintered at temperatures 850 and 900 °C. The resulting glass-ceramics were characterized microstructurally, physically, and mechanically. The cavitation erosion of samples was evaluated. The cavitation rate was 0.015 mg/min for the sample sintered at 850 °C, and 0.0053 mg/min for the sample sintered at 900 °C. The leaching of heavy metals in glass-ceramic samples was determined using the Toxicity Characteristic Leaching Procedure. A low concentration of heavy metals in the leaching solution showed that heavy metals were successfully incorporated in the glass matrix and that obtained glass-ceramics are ecologically safe for usage. Both samples exhibit good resistance to cavitation erosion, suggesting their potential as possible replacements for structural ceramics commonly employed components of hydraulic machinery.

AB  - By maintaining a large number of local pepper genotypes, it is possible to preserve a large number of desirable genes that can be used in different pepper selection programs. The aim of this study was to classify a part  of  the  collection  of  15  genotypes  (11  populations  and  4  varieties  originating  from  autochthonous populations) of peppers originating from Republic of Serbia. Morphological characteristics (weight, length, width,  pericarp  thickness,  color  before  fruit  ripening,  shape  and  number  of  fruit  chambers)  and  10 phytochemical parameters of the fruit (carbohydrates, essential oils, ash, cellulose, beta carotene, potassium, iron, vitamin C, total phenols, antioxidant activity) were studied. Using statistical multivariate techniques (PCA and Cluster analysis), the degree of variation between local populations was assessed and diversity was determined based on the morphological and nutritional characteristics of pepper fruits. Morphological traits were determined using two main components that accounted for 70.3% of the variability. These components accounted for 49.8% of the variation in nutritional traits. The ‘Čokotanka’ population would be suitable for individual selection and reduced divergence within the population, since it has 6 tested traits that resulted in high  diversity  index.  Populations  ‘Stojankina  kletva’,  ‘Lalić’  and  ‘Strižanka’  would  be  suitable  for recombination of genes to improve the properties of individual selection programs for this vegetable species

AB  - The concept of a bio-based economy has been adopted by many advanced countries around
the world, and thermochemical conversion of waste biomass is recognized as the most effective
approach to achieve this objective. Recent studies indicate that hydrothermal carbonization (HTC)
is a promising method for the conversion of waste biomass towards novel carbonaceous materials
known as hydrochars. This cost-effective and eco-friendly process operates at moderate temperatures
(180–280 ◦C) and uses water as a reaction medium. HTC has been successfully applied to a wide
range of waste materials, including lignocellulose biomass, sewage sludge, algae, and municipal solid
waste, generating desirable carbonaceous products. This review provides an overview of the key
HTC process parameters, as well as the physical and chemical properties of the obtained hydrochar.
It also explores potential applications of produced materials and highlights the modification and
functionalization techniques that can transform these materials into game-changing solutions for a
sustainable future.

AB  - Numerous chemical compounds present in natural waters and wastewater are resistant to
conventional water treatments and persist in treated effluents. Among these substances,
pharmaceuticals, due to their widespread use, raise special concern due to their potentially
harmful effects on human health especially when they reach drinking water. One of the most
efficient technique for removal of pharmaceuticals from polluted water is their adsorption on
various adsorbents, such as activated carbons, clays (kaolin, bentonite, etc.) and zeolites. In
this study, the potential of modified bentonite for removal of carbamazepine, a
pharmaceutical with anticonvulsant and mood-stabilizing properties, was investigated. The
natural bentonite from Šipovo deposit, Bosnia and Herzegovina, was modified with the
cationic surfactant Arquad®2HT-75 in amounts equivalent to 50% and 100% of the
bentonite's cationic exchange capacity. Characterization of prepared samples by Fouriertransform
infrared spectroscopy and Simultaneous Thermal Analysis, confirmed presence of
surfactant in modified bentonites. Results on carbamazepine removal by modified bentonites
showed that its adsorption increased with increasing of the amount of surfactant as well as
with increasing of the initial pharmaceutical concentration. The highest adsorption of
carbamazepine was achieved with bentonite containing the highest amount of surfactant.
Since the natural bentonite has no affinity to remove carbamazepine, these findings suggest
that modified bentonite is a promising adsorbent for its removal from contaminated water.

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.

AB  - Отпадне воде представљају велики еколошки притисак на читав екосистем.
Загађујуће материје у отпадној води, као што су боје, могу изазвати токсичне после-
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
контакта, температура. Добијеии резултати показују висок адсорпциони капацитет 74
mg g-1 и ендотермну природу процеса адсорпције.
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
adsorption process.

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
контакта, температура. Добијеии резултати показују висок адсорпциони капацитет 74
mg g-1 и ендотермну природу процеса адсорпције., 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
adsorption process.",

AB  - The removal of organic and inorganic sulfur from the Bogovina Basin subbituminous coal by
electrochemical redox reactions was performed. The effect of presence of active bromine species
on the desulfurization process was monitored. The desulfurization was performed in inorganic
acidic solutions that contained different bromide concentrations and in pure acid solution. To
determine the optimal conditions for the desulfurization process, polarization curves were
recorded in three different electrolytes: 0.1 M H2SO4, 0.1 M H2SO4 + 0.01 M KBr, and 0.1 M
H2SO4 + 0.1 M KBr using graphite and dimensionally stable anode (DSA) electrodes as the
anode, while in all cases stainless steel S31603 electrode was used as cathode. By analyzing the
results obtained from the polarization curves, 0.1 M H2SO4 and 0.1 M H2SO4 + 0.1 M KBr were
chosen as the most suitable electrolytes. Also, it was found that the DSA anode showed better
results in terms of energy efficiency of the process compared to the graphite anode and therefore
it was selected for the coal desulfurization process. It is considered that finely suspended coal
particles in an electrolyte can behave according to bipolar electrochemistry. Coal was treated
for 4 hours in two selected electrolytes. The suspension was sampled at different times up to 240
min from the beginning of the process. Sulfur content in coal was determined by elemental
analysis. The results showed that the sulfur content decreases faster in the case of the electrolyte
containing KBr, i.e. that the desulfurization effect is significantly better than in the case of the
system containing only H2SO4. It can be concluded that active bromine species accelerate the
desulfurization process and thus improve energy efficiency.

AB  - One of the most interesting secondary raw materials within the Kolubara Basin is diatomaceous earth or diatomite, with reserves of 308.670 t in fields B and C. Chemical and mineralogical tests were performed on diatomaceous earth samples. The results of these tests are presented in this paper. Diatomite is a soft sedimentary rock formed by the deposition of cell walls (frustulae) of single-celled algae-diatoms at the bottom of sea and lake basen. Diatom frustules consist of two parts that lie on top of each other and represent a highly porous skeleton of amorphous hydrated silica. Diatom frustule size ranges from 1 μm to 1 mm, usually 10-200 μm.The specific area (SBET (m2/g)) is 47.6. The SEM/EDS, BET and FTIR methods were used for characterization. Based on the presented results, diatomaceous earth can be used in the pharmaceutical, ceramic and food industries.

AB  - The corn cob was investigated as available agrowaste material for the production of potential efficient material for heavy
metals removal. The hydrothermal carbonization (HTC) technology is one of the appropriate methods for biomass
transformation into high-value carbonaceous products than can be utilized as adsorbents. In this study, modified pyrohydrochar
derived from corn cob (MCC) was effectively prepared by modification with Mg-Fe solution and pyrolysis.
This material was used for Pb ions removal from aqueous solutions. The effect of solution pH, contact time and initial Pb
concentration were examined in batch system. The achieved results revealed that the most effective Pb adsorption take
place at pH 5. The experimental results were fitted to Langmuir, Freundlich, Sips and Redlich-Peterson isotherm models.
The best data fit was achieved with the Sips isotherm model with maximum adsorption capacity for Pb removal of 214.9
mg/g. Additionally, the experimentally results from kinetic study were fitted by pseudo-first and pseudo-second order
models. According to kinetic parameters, the Pb removal using MCC follows pseudo-second order model, which assumes
that chemical interaction between Pb ions and functional groups on the MCC surface was involved in metal adsorption.
According to data from this investigation and in comparisons to other adsorbents can be concluded that investigated
material can be used as potential suitable adsorbent of Pb from aqueous solutions.

AB  - Magnetic iron oxide nanomaterials, which enable a multitude of uses, are given special focus in the fields of biomedicine and environmental protection. The detection, sorption, and/or degradation of inorganic (lead, chromium, arsenic, and cadmium), organic (dyes, pharmaceuticals, pesticides, phenols, and benzene), and biological (viruses and bacteria) pollutants can all be effectively accomplished with the use of magnetic nanoparticles. Magnetic iron oxide nanomaterials are in particular focus for use as hyperthermia media in cancer treatment and as magnetic resonance imaging (MRI) contrast agents. The possibility of magnetic separation of such materials, due to their essential properties under the influence of an external magnetic field, reduces production costs and also prevents the production and accumulation of toxic waste. Among the many metal oxide nanomaterials, magnetite (Fe3O4) and maghemite (γ-Fe2O3) are currently the only two magnetic materials approved by the US Food and Drug Administration (FDA) for human use as iron deficiency therapeutics and as contrast agents for MRI. Here, we synthesized nanoparticles of magnetite (Fe3O4) by the method of reduction-precipitation and characterized. Additionally, potential binding of brilliant green dye on Fe3O4 and construction of innovative magnetic composite was investigated. The physicochemical features were explored using X-ray diffraction (XRD), 
Fourier-transform infrared spectroscopy (FTIR), and field emission scanning electron microscopy (FESEM). XRD analysis confirms formation of the crystal phase of magnetite. The presence of magnetite nanoparticles is shown by typical groups for the peaks of iron compounds at a lower wavelength (≤ 700 cm-1) that are characteristic of the Fe-O bond. Morphological analyzes with FESEM showed that magnetite is a composite of nanospheres and nanorods that provide a large surface area. Dye binding study was performed using UV visible and FTIR spectrometer.

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.
