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  - 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 contamination of the water bodies by diesel oil (DO) and its water-soluble fraction (WSF) represents one of the most challenging tasks in the management of polluted water streams. This paper contains data related to the synthesis and characteristics of the plum stone biochar material (PmS-B), which was made from waste plum stones (PmS), along with its possible application in the sorption of the WSF of DO from contaminated water. Techniques applied in sample characterisation and comparisons were: Elemental Organic Analysis (EOA), Scanning Electron Microscopy−Energy Dispersive X-ray Spectroscopy (SEM-EDX), Fourier Transform Infrared Spectroscopy (FTIR), pH (pHsus) and point of zero charge (pHpzc). In order to increase the overall efficiency of the removal process, sorption and bioremediation were subsequently combined. Firstly, PmS-B was used as a sorbent of WSF, and then the remaining solution was additionally treated with a specific consortium of microorganisms. After the first treatment phase, the initial concentration of diesel WSF was reduced by more than 90%, where most of the aromatic components of DO were removed by sorption. The sorption equilibrium results were best fitted by the Sips isotherm model, where the maximum sorption capacity was found to be 40.72 mg/g. The rest of the hydrocarbon components that remained in the solution were further subjected to the biodegradation process by a consortium of microorganisms. Microbial degradation lasted 19 days and reduced the total diesel WSF concentration to 0.46 mg/L. In order to confirm the non-toxicity of the water sample after this two-stage treatment, eco-toxicity tests based on a microbial biosensor (Aliivibrio fischeri) were applied, confirming the high efficiency of the proposed method.

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  - 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  - The performance of thermo-insulation rendering mortars with alternations in ratios
of powdered cordierite and talc was examined. The goal was to confirm that recycled
kilnware cordierite can be reapplied in the mortar design without significant deterioration in
performance in comparison with OPC mortar. Differential thermal analysis was employed for
examining thermally induced reactions. The cavitation erosion, in testing sequences ranging
from 30 to 120 minutes, was used to assess the compactness of the mortar structure. The
physico-mechanical properties of experimental mortars were investigated. The morphologies
of the mortar tablets upon cavitation were studied using a scanning electron microscope. It
was established that cordierite and talc filler in amounts up to 20% enhance microstructural
packing and mechanical strengths due to improved cementation and therefore contribute to
cavitation erosion resistance. Higher amounts of talc cause structural degradation and mass
loss during cavitation tests. Reducing manufacturing costs, energy consumption, and
greenhouse gas emissions are the main objectives of the production of this waste-based
construction composite, as the reuse of waste materials can help achieve a number of
Sustainable Development Goals.

AB  - Every year around 1.2 Mt of Electric Arc Furnace (EAF) dust and around 50 kt of Cupola Furnace (CF) dusts are generated
in Europe. Both materials are classified as hazardous waste due to significant concentration of Zn, Cd, Cr, Ni and Pb, which burden the metallurgical industry, albeit their possibility to be considered as an alternative source of valuable metals. Around 30 steelworks in the East-Southeast European Regional Innovation Scheme (ESEE RIS) region exploit EAFs for scrap-based steelmaking. However, the dusts generated from the exhaust gases abatement cannot be profitably recycled due to the absence of recycling plants operating in these areas, which implies that the dust generators have additional costs due to the dust ransportation to the nearest Zn recovery plant, since presence of toxic substances prohibits their landfilling. Thanks to the extensive knowledge on the extraction of a wide range of compounds from steelmaking dusts, as well as the capacity of reutilisation of residues after extraction in the building and construction industry, the DustRec project aims at the recovery of all the economical compounds within the dusts (Zn, Pb, Cu, Fe and others) hence minimizing the final waste landfilling and generate an economically feasible process with improved environmental and societal impacts. The proposed approach includes several emerging techniques from innovative magnetic and gravity separation methods to new pyro- and hydro-metallurgical reprocessing technologies for the separated fractions. In this paper, eight different dusts from EAF and CF were collected all around the partners’ countries and chemically, thermally and physically characterized in order to select the most optimal samples to be reprocessed for improved valuable extractions. Due to their high concentration of ZnO and PbO, three EAF dusts were identified as promising raw materials while two CF dusts will be employed as co-adjuvant for magnetic
fraction reduction and smelting. Preliminary hints about the next reprocessing steps are also revealed.

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.

AB  - INTRODUCTION: Electrochemical methods were employed for synthesizing composites intended for applications in
medicine as antibacterial coatings on titanium bone implants or as highly efficient antibacterial hydrogels for
accelerated wound healing.
EXPERIMENTAL: Hydroxyapatite-based coatings were single-step electrophoretically deposited from fourcomponent
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, Sigma-Aldrich), 0.05 wt% chitosan powder (CS,
medium molecular weight, 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. For poly(vinyl alcohol)/chitosan (PVA/CHI) hydrogel synthesis poly(vinyl alcohol) powder (PVA, Sigma Aldrich,
USA), chitosan powder (CHI, Sigma Aldrich, USA), graphene (Graphene Supermarket, USA), glacial acetic acid (Beta
Hem), silver nitrate (MP Hemija), potassium nitrate (Centrohem, Serbia) were used. For antibacterial properties
evaluation, monobasic and dibasic (Sigma Aldrich, USA) potassium phosphates were used. Cell culture suspensions for
cytotoxicity tests were prepared using MTT tetrazolium salt, EDTA, fetal calf serum and antibiotic-antimycotic solution
(Sigma Aldrich, USA).
RESULTS AND DISCUSSION: Surface modification of titanium with innovative bioactive coatings enhances
biomineralization and reduces post-operation pain and infection risk. Using powerful single-step electrophoretic
deposition (EPD) at a constant voltage we have produced various hydroxyapatite-based composite bioceramic coatings
in combination with polymers (lignin, chitosan), graphene, and antibacterial agents (silver, gentamicin).
Electrochemical methods enable in situ synthesis of AgNPs inside polymer matrices, with the main advantage being
the complete absence of any chemical reducing agents that are often toxic and difficult to remove from the material.
The electrochemical reduction of Ag+ ions is achieved only using electrical current or pure hydrogen gas that is generated
at the cathode in aqueous electrolytes, which allows for obtaining completely green and non-toxic product.
Modifications in the synthesis process also enable the control of AgNPs properties, such as size and concentration.
CONCLUSIONS: Composite antibacterial coatings were obtained on titanium plates using EPD. Strong antibacterial
activity against E. coli and S. aureus was found. Biocompatibility was confirmed using in vitro MTT testing since a noncytotoxic
effect was shown towards healthy human peripheral blood mononuclear cells PBMC, fibroblast cell lines MRC-5
and L929, suggesting high potential for bone tissue engineering and medical applications. Hydrogels composed of physically
cross-linked poly(vinyl alcohol)/chitosan with embedded AgNPs were successfully developed for applications as antibacterial
wound dressings due to their highly favorable properties of silver release, antibacterial activity, and non-toxicity.

akcidentnih situacija. Slučajno ispuštanje jedinjenja azota, konkretno veštačkih đubriva, ima
veoma štetan uticaj na kvalitet vode i vodene ekosisteme. U ovom radu je navedeno nekoliko
primera akcidentnih situacija ispuštanja azotnih đubriva u površinske vode, uključujući i
akcident koji se desio u Republici Srbiji, kada je usled plovidbene nezgode, oko 1000 t veštačkog
azotnog đubriva potonulo u reku Dunav. Svi ovi akcidenti ukazuju na značaj prevencije ili
naknadnog umanjenja uticaja ovih jedinjenja na živi svet. U cilju prevencije budućih akcidenata i
ublažavanja efekata već nastalih, potrebno je izraditi planove reagovanja u vanrednim
situacijama. Za održivo upravljanje rečnim slivovima, ključno je razumevanje promena koje

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  - 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  - This study presents comparison of our recently formulated two compartmental model with General fractional derivative (GFD) and Korsmeyer-Peppas, Makoid-Banakar and Kopcha diffusion models. We have used our GFD
model to study the release of gentamicin in poly (vinylalcohol)/chitosan/gentamicin (PVA/CHI/Gent) hydrogel aimed for wound dressing in medical treatment of deep chronical wounds. The PVA/CHI/Gent hydrogel was prepared by physical cross linking of poly(vinyl alcohol)/chitosan dispersion using freezing-thawing method, and then was swollen for 48 h in gentamicin solution, at 37 °C. Different physico-chemical (FTIR, SEM), mechanical and biological (cytotoxicity, antibacterial activity) properties have been determined. The concentration of released gentamicin was determined
using a high-performance liquid chromatography (HPLC) coupled with mass spectrometry (MS). The ratio between concentration of released gentamicin and initial concentration of gentamicin in the hydrogel was monitored for the
prolonged time period in order to obtain gentamicin release profile. It was proven that our novel diffusion GFD model better fitted with experimental data, and enabled the determination of diffusion coefficient precisely for the entire time period.

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.

The crystallization of glasses has been studied by using DTA, HSM and XRD methods. Sintered phosphate glass-ceramics containing bioactive β-CaP2O6 and β-Ca3(PO4)2 phases were successfully prepared. The increasing presence of Sr (1-5 %), as well as Ti at the expense of phosphate mole fraction in polyphosphate bioactive glass increases the density of these glasses, transformation temperature and resistance to crystallization.

AB  - Polyphosphate glasses are a class of bioactive glasses that have gained significant attention in recent years due to their unique properties and potential applications in various fields, particularly in the area of biomedical engineering. These glasses exhibit excellent biocompatibility, which is a crucial requirement for biomaterials. Furthermore, their dissolution and degradation rates can be tailored by modifying their composition, allowing for control over their bioactivity and biodegradability. Polyphosphate glasses also have the ability to form a hydroxyapatite-like layer on their surface when in contact with biological fluids, which facilitates their integration with surrounding tissues. The unique properties of polyphosphate glasses make them promising candidates for various biomedical applications, including bone tissue engineering, drug delivery, and wound healing. This paper presents the thermal characterization of two bioactive polyphosphate glass compositions with the addition of strontium, to investigate the sintering and crystallization processes. The samples were synthesized using the melt-quenching method and then sintered at various temperatures. Differential scanning calorimetry (DSC) and X-ray diffraction (XRD) were used to analyze the thermal behavior and crystalline phases formed during sintering. Our results showed that sintering and crystallization are separate processes for both compositions. The addition of strontium to the glass improved its sintering behavior, resulting in a denser glass structure. Moreover, strontium incorporation did not affect the formation of the crystalline phase during sintering. These findings provide useful insights into the design and development of bioactive polyphosphate glass compositions for bone tissue engineering applications.

AB  - This paper shows the dissolution behavior of polyphosphate glass in demineralized water and 2% citric acid solution at temperatures: 15, 20, 30, 37 and 50 °C. The influence of the solvent type on the diffusion coefficients of the modifying cations, under static conditions, is also presented. The diffusion coefficients, determined from concentration profiles of the modifying cations, are calculated to be in the range of 0.27 to 350x10-14 m2/h for dissolution in demineralized water, and in the range of 3.6 to 148x10-12 m2/h for the dissolution in 2% citric acid solution. The values of activation energy of cations diffusion in demineralized water are in the range from 68.32 to 105.41 kJ/mol, while for 2% citric acid solution they are in the range from 39.28 to 55.34 kJ/mol.

AB  - Great waste production alongside limited natural resources represents huge environmental and economic problems worldwide. Sustainable waste management and industrial production can reduce pollution and gain some economic benefits. Eco-friendly thermal insulators such as foam glasses can be produced using secondary raw materials in open-loop recycling. Foam glasses were successfully produced using green bottle glass and sugar beet factory lime (SBFL), CaCO3-rich waste as a novel foaming agent. Glass powder was mixed with different amount of SBFL, uniaxially pressed at 20 MPa, and sintered at different temperatures. The influence of sintering temperature and the addition of a foaming agent was examined. Obtained samples were mechanically, thermally, and microstructurally characterized. Results showed that samples sintered at 800 °C have the best properties.  Obtained  foam glasses can be used in a variety of industries where thermal insulation, non-flammability, and non-toxic materials are required.

AB  - Open loop glass recycling is a process where the glass is recycled into a new product. Glass recycling helps reduce landfill waste. Glass takes up significant space in landfills and does not decompose. In many countries, landfills are filling up faster than we can create new ones. Recycling glass reduces the volume of waste, and increases the lifespan of landfills. One of examples of open loop recycling of glass is glass foam produciton. Glass foam production is a process that involves the creation of a light-weight glass material with a foam-like consistency. This type of glass is made by mixing a foaming agent with glass powder and heating to temperatures where decomposition of a foaming agent and sintering of glass happens. This results in the creation of a material that is light, strong, and has thermally-insulating properties. Milled flat glass was mixed with sugar beet factory lime, a CaCO3 – rich waste wich has role of a foaming agent, in order to enter 5% CaCO3 in mixture and pressed at 20 MPa in hydraulic press. Raw pellets were sintered at 800 °C for 30 min. In obtained glass foam phase composition, pore size distribution, compressive strength and thermal conducitivity were determined. Glass foam is emerging as a flexible, cost-effective, and sustainable material that can be utilized in numerous applications to promote sustainable development. Its features such as high insulation capacity, lightweight, and durability make it an ideal material for a wide range of industries.

AB  - The decrease of fossil fuel resources as well as associated pollution induced by its applications has
increased the interest in findings of renewable fuels from various biomasses such as wood, energy
crops, and various waste disposed from agricultural and food-industry activities. Especially
interesting is lignocellulosic waste (LCW) biomass, found in large quantities after processing of the
raw biomass, which pose certain energetic properties that might be used to fulfil future
sustainability demands. This paper describes the thermal decomposition of waste peach stones (PS)
investigated via thermogravimetric (TG) analyses. TG/DTG analyses provided a set of experimental
mass loss data (obtained under different conditions), which were modelled by different kinetic
models, resulting in parameters that might be used for industrial application of the tested biofuel.
The goal of analyzing the kinetics of thermal degradation was to establish a relationship between
the rate of degradation, degree of conversion (α) and temperature. In this sense, the investigation of
the kinetics of thermal degradation was performed in non-isothermal conditions, with the heating
speed varying from 5 to 20 ºC/min in an oxygen stream. Activation energy (Ea) of the PS thermal
degradation was determined using Flynn-Wall-Ozawa (FWO) isoconversional model free method.
The possible reaction mechanism that controls the process was investigated by the method of Coats-
Redfern (C-R). The values of the Ea obtained by this method were not constant with the change in
the degree of conversion (α), indicating that the thermal decomposition of PS represents a complex
process that cannot be described by a one-step reaction in the entire range of conversions. PS
waste samples investigated in this paper, have certain physical and chemical properties which
satisfy request for energy density, small ash content and safe burn out. Presented results might
support the value of biowaste in a future circular bio economy of Serbia.
