AB  - Polymer resins based on acrylates obtained from Bis-GMA (Bisphenol A glycide methacrylate), which is suitable for photopolymerization, are used in dentistry for various purposes due to the ease of application and the possibility to influence their properties by adding reinforcements of different shapes, crystal structure and chemical compositions. Reinforcement in the form of particles based on MgAlLDH (layered double hydroxide) deposited on silica obtained from rice husks on two substrates. A metal base and glass were used. The adhesive properties are important in order to see the possibility of using these materials in applications. In order to measure the adhesive properties of the material, the composite microhardness measurement method is used by applying different loads in order to evaluate the adhesion parameter that shows the effect of the coating on the substrate. It was compared to how a pure photopolymerizing acrylate matrix bonds with a chromium-based dental alloy substrate that is used in the production of different parts of dentures by bonding to a glass substrate. Then, it was compared how composite materials are bonded to both substrates. Adhesion was monitored through the change in wetting angle between the composites, and the results were compared with the results of microindentation. It was shown that the addition of composite particles increases the adhesive properties of the composite compared to the pure matrix and that better adhesion is achieved between the composite and the metal substrate than between the composite and the glass substrate.

AB  - Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modified
plant provenance biosilica particles were synthesized and characterized. An unsaturated polyester resin was obtained from
waste poly (ethylene terephthalate (PET). Biosilaca particles are made from rice husk biomass. The surface of the produced
silica particles was modified using three different silanes: 3-trimethoxysilylpropyl methacrylate (MEMO), trimethoxyvinylsilane (TMEVS), and 3-aminopropyltrimethoxysilane (APTMS). The microhardness test method was used to investigate
the mechanical properties of synthesized composite material with variations in dwell times and applied loads. Optimization of
composite microhardness value prediction in function of synthesized parameters (type of modification of silica particles) and
measurement parameters (applied loads and dwell times) was done using the method of response surface methodology (RSM)
regression analysis. The maximal microhardness values (0.459 GPa) were obtained of type modification of silica particles with
vinyl with 80% confidence for 120 experimental variables. This method can be used to choose the optimal dwell time and load
for comparison of measurements between different composite materials and to enable the choice of the material in terms of
optimization of the quality of reinforcement and quality of interphase determined by surface modification.

AB  - Population growth, the development of agriculture, industry, and mining, caused the creation of an increasing amount of  wastewater. Due to the discharge of wastewater, without prior treatment, the quality of water resources is impaired.  Polluting substances, such as pesticides, have a negative impact on human health and the environment. Heavy pollution  of both surface and underground water is one of the biggest problems associated with the use of pesticides. They reach  human organisms indirectly via agricultural products. Most pesticides are more or less toxic, some of them are highly  soluble in water. In recent years, special attention has been paid to the development of methods for the treatment of  wastewater contaminated with pesticide residues, in order to partially reduce or eliminate their further impact on humans,  plants, and the environment. Among many processes, the photocatalytic degradation process has proven to be a very  effective process for the removal of pesticides from wastewater. Photocatalytic degradation implies the breakdown of  various types of toxic organic substances into simpler molecules, such as ions, water, etc.  In this paper, the photocatalytic degradation of the pesticide mesotrione (MS) using ZnO photocatalyst is presented. The  degradation of the pesticide compound was studied using Shimadzu 1800 analytical UV-VIS spectroscopy. As a  replacement for UVC radiation, a solar-imitated irradiation Ultra Vitalux (UV) lamp (300W) was used. Degradation  kinetics follows pseudo-first order. After 240 minutes, the MS was completely degraded.

AB  - This paper presents sustainable technology for environmentally friendly composite production. Biobased unsaturated polyester resin (b-UPR), synthesized from waste polyethylene terephthalate (PET) glycosylate and renewable origin maleic anhydride (MAnh) and propylene glycol
(PG), was reinforced with unmodified and vinyl-modified biosilica nanoparticles obtained from
rice husk. The structural and morphological properties of the obtained particles, b-UPR, as well as
composites, were characterized by Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic
resonance spectroscopy (NMR), scanning electron microscopy (SEM), and transmission electron
microscopy (TEM) techniques. The study of the influence of biosilica modification on the mechanical
properties of composites was supported by hardness modeling. Improvement of the tensile strength
of the b-UPR-based composite at 2.5 wt.% addition of biosilica modified with vinyl silane, named
“b-UPR/SiO2
-V” composite, has been achieved with 88% increase. The thermal aging process applied

abstract = "This paper presents sustainable technology for environmentally friendly composite production. Biobased unsaturated polyester resin (b-UPR), synthesized from waste polyethylene terephthalate (PET) glycosylate and renewable origin maleic anhydride (MAnh) and propylene glycol
(PG), was reinforced with unmodified and vinyl-modified biosilica nanoparticles obtained from
rice husk. The structural and morphological properties of the obtained particles, b-UPR, as well as
composites, were characterized by Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic
resonance spectroscopy (NMR), scanning electron microscopy (SEM), and transmission electron
microscopy (TEM) techniques. The study of the influence of biosilica modification on the mechanical
properties of composites was supported by hardness modeling. Improvement of the tensile strength
of the b-UPR-based composite at 2.5 wt.% addition of biosilica modified with vinyl silane, named
“b-UPR/SiO2
-V” composite, has been achieved with 88% increase. The thermal aging process applied
to the b-UPR/SiO2
-V composite, which simulates use over the product’s lifetime, leads to the deterioration of composites that were used as fillers in commercial unsaturated polyester resin (c-UPR).

AB  - Vaccinium myrtillus L. (bilberry, Ericaceae), a perennial, wild, and small deciduous shrub that grows in the mountains and forests of Europe. The leaf extracts are widely used in traditional medicine due to their astringent, antiseptic, antioxidant, anti-inflammatory, hypolipidemic, and hypoglycemic activities. Microwave-assisted extraction provides various benefits, including reducing solvent consumption and extraction time and increasing extraction yield. In the present study, bilberry extracts were prepared using dried leaves, pure ethanol, or an ethanol-water mixture, and different temperatures in a microwave reactor (60, 100, and 160 ◦C). The extracts were examined in terms of total polyphenol content (TPC) and antioxidant activity. The TPC of the 96% ethanol extracts rose with the increase of the extraction temperature; the extract obtained at 60 ◦C (37.2 ± 0.5 mg gallic acid equivalents (GAE)/g of plant material)<the extract at 100 ◦C (46.6 ± 0.3 GAE/g)<the extract at 160 ◦C (55.1 ± 0.5 mg/g). The TPC of the 50% ethanol extract prepared at 60 ◦C was significantly lower (54.9 ± 1.0 mg GAE/g) in comparison to the extracts obtained at 100 and 160 ◦C (58.3 ± 1.0 and 58.0 ± 1.5 mg GAE/g, respectively). ABTS antioxidant capacity was higher in the 50% ethanol extracts compared to 96% ethanol parallels, while in the DPPH assay, there was no statistically significant difference between the 50 and 96% ethanol extracts. Due to higher TPC and anti-ABTS activity and reduced consumption of organic solvent, a 50% ethanol extract of V. myrtillus was favored, while the optimal temperature was 60 ◦C for the extract with the highest antioxidant capacity and 100 ◦C for the extract with the highest amount of polyphenols.

AB  - In the last decades, the rapid development of industrial and agricultural activity caused the release of different organic/or nonorganic pollutants in water, earth, and air which lead to a threat to human health and the ecological environment. These pollutants contain toxic heavy metals, organic dyes, pesticides, pharmaceutics, and others (Aboua et al., 2015). Organic dyes are visible pollutants used as coloring agents in, textiles, plastics, paper, food industries, etc. For their removal from wastewater, eco-friendly treatment is needed. Among many process purification, the process of adsorption proved to be an effective method for removing pollutants that are present in water, such as pesticides, dyes, and heavy metal ions. Due to the specific properties of polluting substances, the goal is to develop a cheap, efficient, environmentally friendly material. Among them, cotton-based materials can be obtained from various natural sources and can be employed as inexpensive adsorbents. Their adsorption capacities for pollutants can be related to chemical treatment. In general, chemically modified cellulose exhibits higher adsorption capacities for various aquatic pollutants than their unmodified forms. In this aim, oxidized cotton fabric was used in this work, which was chemically modified with citric acid and ethyl lysinate, respectively. In order to activate the surface of the fabric for chemical modification and increase absorption ability, carboxyl and aldehyde functional groups were introduced using hydrogen peroxide. Then the oxidized cotton fabric was cross-linked with citric acid and ethyl lysinate (Co-CA-Et-Lys) using diisopropylcarboimide to promote ester and amide groups formation. The structure of obtained material was analyzed by using the ATR-FTIR technique. The resulting modified fabric proved to be a good adsorbent for the removal of cationic dyes malachite green (MG) and methylene blue (MB). Its adsorption behavior with respect to the pH, adsorption time, and initial concentration was investigated. Based on the obtained results, it was concluded that the adsorption equilibrium was reached after 1 h for both Malachite Green (MG) and Methylene Blue (MB). Adsorption kinetics data were satisfactorily fitted with the pseudo-second-order rate model (PSO), and adsorption data were best fitted using Langmuir model. The Langmuir maximum adsorption capacities for Co-CA-Et-Lys cross-linked fabric showed a maximum of 168.4 mg/g and 124.9 mg/g for MG and MB, respectively. Compared to other adsorbents based on natural materials, oxidized cotton fabric showed much better sorption properties.

AB  - Vaccinium myrtillus leaf waste extracts were prepared using lactic acid+amonium acetate and maceration, heat- and ultrasound-assisted extractions (HAE and UAE, respectively). The obtained extracts were characterized via analysis of total polyphenol content (TPC), pH, zeta potential, conductivity, density, surface tension, viscosity, and antioxidant potential. The TPC was the highest in the extract prepared in HAE (53.0±0.9 mg GAE/g), whereas the extracts from maceration and UAE possessed significantly lower TPC (50.4±0.7 and 49.5±0.4 mg GAE/g). The ABTS radical scavenging potential was the highest in the extract prepared in HAE (38.4±1.1 µmol TE/g), followed by the extract obtained using UAE (33.7±1.5 µmol TE/g) and maceration (30.2±1.7 µmol TE/g). The DPPH antioxidant capacity followed the same trend: HAE>UAE>maceration. The zeta potential was low in all extracts (2.66±0.48 mV for macerate, 2.57±0.20 mV for HAE, and 3.17±0.13 mV for UAE), while the conductivity was in the range of 1.87±0.13 and 1.84±0.11 mS/cm (maceration and HAE) to 2.10±0.11 mS/cm (UAE). The density varied from 1.105±0.009 g/mL for macerate to 1.122±0.006 and 1.117±0.001 g/mL for HAE and UAE extracts. There were no statistically significant differences in the surface tension and viscosity (~23.5 mN/m and ~5.5 mPa∙s). The highest TPC and antioxidant potential were measured in the extract obtained using HAE, whereas the extract prepared by ultrasound waves possessed the highest zeta potential and conductivity. Therefore, the extraction technique should be chosen depending on the future application of V. myrtillus extract.

AB  - Vaccinium myrtillus L.(Ericaceae), a perennial, wild, and small deciduous shrub that grows in the mountains and forests of Europe, contains anthocyanins, phenolic acids, flavonoids, fatty acids, stilbenes, iridoid glycosides, dietary fibers, vitamins, and minerals. The leaves' extracts are widely used in traditional medicine due to their astringent, antiseptic, antioxidant, anti-inflammatory, skin-rejuvenating, lipid-lowering, hypolipidemic, and hypoglycemic activities. The novel extraction techniques, including ultrasound-assisted extraction, provide various benefits, such as reducing solvent consumption and extraction time and increasing extraction yield, and quality. Hence, in the present study, V. myrtillus extracts were prepared using dried leaves (0.66 g), 50% ethanol as the extraction solvent (20 mL), and maceration (60 min) or ultrasound-assisted extraction (ultrasound probe, amplitude of 60% for 5 min). The obtained extracts were examined in terms of total polyphenol content (TPC) and antioxidant activity (ABTS, DPPH, FRAP, and CUPRAC assays). The TPC of the extract prepared using maceration was 55.2±0.7 mg gallic acid equivalents (GAE)/g of plant material, while the TPC of the extract prepared using an ultrasound probe was 55.6±1.0 mg GAE/g. The DPPH radical scavenging activities of the extracts correlated with the TPC and amounted to 1.81±0.05 mg/mL for macerate and 1.79±0.02 mg/mL for the extract obtained using an ultrasound probe, whereas ABTS antioxidant capacity did not correlate with the polyphenol concentration, 31.4±0.9 µmol Trolox equivalents (TE)/g for the macerate and 43.4±1.1 µmol TE/g for the extract from the ultrasound-assisted extraction. According to the results of FRAP and CUPRAC assays, the antioxidant potential was similar for both extracts (15.3±0.2 and 15.5±0.2 µmol Fe2+/g and 45.7±0.5 and 46.0±0.7 µmol TE/g, respectively). Due to higher ABTS radical scavenging potential and significantly shorter extraction time, V. myrtillus extract prepared using an ultrasound probe was favored. The present research was an initial step in the preparation of V. myrtillus extracts which can be potentially implemented in food, pharmaceutical, and cosmetic formulations.

The DPPH radical scavenging activities of the extracts correlated with the TPC and amounted to 1.81±0.05 mg/mL for macerate and 1.79±0.02 mg/mL for the extract obtained using an ultrasound probe, whereas ABTS antioxidant capacity did not correlate with the polyphenol concentration, 31.4±0.9 µmol Trolox equivalents (TE)/g for the macerate and 43.4±1.1 µmol TE/g for the extract from the ultrasound-assisted extraction. According to the results of FRAP and CUPRAC assays, the antioxidant potential was similar for both extracts (15.3±0.2 and 15.5±0.2 µmol Fe2+/g and 45.7±0.5 and 46.0±0.7 µmol TE/g, respectively). Due to higher ABTS radical scavenging potential and significantly shorter extraction time, V. myrtillus extract prepared using an ultrasound probe was favored. The present research was an initial step in the preparation of V. myrtillus extracts which can be potentially implemented in food, pharmaceutical, and cosmetic formulations.",

AB  - Thymus serpyllum L. (wild thyme) extracts were prepared using 1 g of plant material and three natural deep eutectic solvents (30 mL, malic acid+maltose, lactic acid+menthol, or citric acid+glycerol with 50% of water) in maceration (90 min). The extracts were characterized in terms of total polyphenol content (TPC), total protein content, extraction yield, zeta potential, conductivity, pH, density, surface tension, and viscosity. TPC was the highest in citric acid+glycerol extract (35.06±1.13 mg gallic acid equivalents (GAE)/g of plant material), whereas malic acid+maltose and lactic acid+menthol extracts possessed similar TPC (29.62±1.11 and 28.94±1.15 mg GAE/g, respectively). Total protein content amounted to 5.55±0.20 mg/g in citric acid+glycerol extract, while significantly lower values were determined in malic acid+maltose and lactic acid+menthol extracts (1.22±0.30 and 1.73±0.18 mg/g, respectively). The extraction yield was the highest for citric acid+glycerol extract, 1.57±0.11%, followed by malic acid+maltose and lactic acid+menthol extracts, 1.28±0.10 and 1.27±0.13%, respectively. Zeta potential (absolute value, as a predictor of potential application in water treatment) was low in all extracts (0.86±0.06 mV for citric acid+glycerol, -0.35±0.09 mV for lactic acid+menthol, and -0.17±0.05 mV for malic acid+maltose extract). The conductivity (as a predictor of antioxidant capacity) was in the range of 2.35±0.21 and 2.71±0.29 mS/cm (citric acid+glycerol and malic acid+maltose extracts) to 5.70±0.23 mS/cm (lactic acid+menthol extract). pH ranged from 1.44 in citric acid+glycerol extract to 1.78 and 1.85 in malic acid+maltose and lactic acid+menthol extracts. Density varied from 1.067±0.003 g/mL for lactic acid+menthol extract to 1.169±0.002 and 1.195±0.005 g/mL for citric acid+glycerol and malic acid+maltose extracts. Surface tension was the highest in citric acid+glycerol extract (38.0±0.4 mN/m), followed by malic acid+maltose and lactic acid+menthol extracts (31.5±0.4 and 25.9±0.1 mN/m, respectively). The viscosity of lactic acid+menthol extract was significantly lower (1.83±0.30 mPa•s) in comparison to malic acid+maltose and citric acid+glycerol extracts (6.64±0.15 and 7.84±0.10 mPa•s, respectively). The highest TPC, total proteins, and extraction yield were measured in citric acid+glycerol extract, while lactic acid+menthol extract possessed the highest conductivity and the lowest density, surface tension, and viscosity. Therefore, the constitution of natural deep eutectic solvent should be optimized depending on the future application of T. serpyllum extract.

AB  - The plants contain a large number of various compounds that exhibit significant antioxidant 
activity. Among them, polyphenols and flavonoids are the most studied compounds with different 
biological properties, including antioxidant activity. The functionalization of cotton fabric with natural compounds from plants results in the material with improved antioxidative properties. In this study, cotton fabrics treated with ethanol and water Thymus serpyllum L. (wild thyme) extracts were investigated in terms of antioxidant properties and chemical composition. In vitro antioxidant capacity of ethanol and water extracts, and the cotton fabric before and after functionalization was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH•), and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS•+) radicals scavenging capacity assays. FTIR and UV–Vis spectroscopy elucidated the structure of the cotton fabric, extracts, and functionalized cotton fabric. FTIR spectroscopy demonstrated that the structure of cellulose was dominated in cotton, and also proved the presence of a low percentage of protein, pectin, oil, fat, and wax, as well as, binding of compounds from the extract by cross-linking with long chains of structure cotton. In dry extracts, the presence of various chemical functional groups was confirmed. UV-Vis analysis identified the active components in T. serpyllum extracts. Namely, absorption values for both spectra (water and ethanol samples) at 215-253 nm, 263-384 nm, are specific for phenolic acids, and flavonoids. Also, one of the aims of the study was to investigate the influence of various extracts (water and ethanol samples) on the antioxidant activity of cotton fabric. All extracts demonstrated excellent antioxidant properties, more potent than the reference antioxidant (ascorbic acid) in both antioxidant assays (between 85-86% in DPPH and 94-96% in ABTS assays). Pure T. serpyllum water extract was the most potent in the DPPH assay (86%), while pure ethanolic extract was the most potent antioxidant in the ABTS assay (96%). The antioxidant capacity of raw cotton fabric was insufficient (4%). On the other hand, in the DPPH assay, samples of cotton fabric with extract showed moderate activity with scavenging activity of 48% and 45% for ethanol and water extracts, respectively. Additionally,
in the ABTS assay, the antioxidant activity of treated cotton fabric was 51% and 46% for ethanol 
and water extracts, respectively.

AB  - Wild thyme contains biologically active compounds, particularly polyphenols (flavonoids and phenolic acids) that exert antitumor, antimicrobial, anti-inflammatory, antioxidant, immunomodulatory, analgesic, and spasmolytic activities. Nevertheless, the mentioned bioactive compounds have low stability, solubility, and bioavailability, thus their application is limited. Liposomal particles have been widely used for the encapsulation of bioactive components, due to their high structural integrity, stability during storage, and controlled release capability. In the present study, phospholipid-cholesterol liposomal particles, as the carrier for wild thyme extract, were developed. The stability of extract-loaded liposomes was monitored for 21 days by measuring vesicle size, polydispersity index (PDI), and zeta potential. The particle size and PDI of extract-loaded liposomes did not change drastically during 21 days of storage and amounted to ~450 nm and ~0.155, respectively. The zeta potential varied in the liposomes and started to decrease after 7 days of storage (from -21.0 mV to 20.3 mV, without a statistically significant difference), while the zeta potential value after 21 days was statistically significantly lower in comparison to the 1st day (19.3 mV). The beneficial effects of polyphenols on human health, as well as showed storage stability of the prepared liposomes highlight the use of the wild thyme extract-loaded phospholipid-cholesterol liposomal particles for potential application in food, pharmaceutical, and cosmetic industries.

AB  - Nickel pollution of water induces several problems for the environment. The purpose of this paper was toinvestigate the adsorption of Ni2+ ions on fabricated biomembranes. The proposed adsorbent was preparedfrom epoxy and amino-functionalized waste cellulose fibers, able to participate in cross-linking with aminoacid lysine - wCell/Mn-Fe_LDH. The prepared material underwent preliminary structural characterizationby 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 themembrane 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 outcomesdemonstrated that environmentally friendly sustainable technology has been successfully developed.

AB  - Worldwide pollution induces a negative impact on the complete environment. Modern societies are becomingmore involved in developing and implementing climate change adaptation policies as a result ofthe enormous hazards that climate change poses to human safety worldwide. One of the biggest problemsthat highly affects climate change is plastic pollution. Also, the utilization of a linear economy prevents theopportunity of solving mentioned problem. Hence, a major component of the strategy for tackling plasticpollution and trying to decrease global weather changes is an implementation of a circular economy. Plastichas to be reduced, reused, and recycled since its widespread consumption has put environmental protectionat risk. PET, also known as polyethylene terephthalate, is a prominent polymer material used forthe production of packaging, particularly plastic bottles. The majority of PET-based products are madeusing raw materials supplied from fossil fuels. However, methods based on biobased materials and recycling-modified products for obtaining novel products from waste PET have fewer greenhouse gas (GHG)emissions than the traditional method. Therefore, the subject of this paper is the innovative technology forthe fabrication of materials by PET recycling. Obtained monomer units - glycolysates were acquired by PETdepolymerization by inducing greener solutions. The resulting glycolysate was structurally modified withmaleic anhydride and finally with 2-octanol to obtain a novel plasticizer. The physicochemical characterizationof the obtained plasticizer, performed by infrared spectroscopy with Fourier transform (FTIR) andNMR spectroscopy, confirmed structural modifications. The mechanical characteristics of the final productwere tested after the plasticizers had been combined with bitumen at a range from 1 to 10 wt.% concentration.In addition, other PET recycling techniques will be presented and discussed. By comparing them,it will be determined which technique is most suitable for recycling with the smallest carbon footprint. Thesecond purpose of the research is to evaluate and contrast the financial and ecological implications of recyclingPET in comparison to other types of waste and renewable energy sources.

AB  - This paper presents the possibilities of making paper with increased water resistance as occupational therapy for people with developmental disabilities. Paper production using biodegradable additives was presented and their hydrophobicity was tested using the drop retention time method. It was found that papers containing an agent used for hydrophobization had a prolonged drop retention time. The efficiency of the functionalization of the paper structure and the hydrophobization agent was confirmed by FTIR-spectroscopy. The mechanical properties of all prepared samples were tested and it was determined that functionalization with rosin maleic anhydride sodium salt Na-(RMA) gives better results compared to sodium abietate (Na-Ab).
AB  - У статті представлені можливості виготовлення паперу з підвищеною водостійкістю як ерготерапії для людей з вадами розвитку. Було представлено виробництво паперу з використанням біорозкладних добавок та перевірено їхню гідрофобність за методом часу утримання краплі. Було виявлено, що папери, що містять агент, який використовувався для гідрофобізації, мали подовжений час утримання крапель. Ефективність функціоналізації структури паперу та гідрофобізатора підтверджено методом FTIR-спектроскопії.

AB  - Cotton-based membranes, due to their exceptional biocompatibility and sustainability,have attracted considerable attention in various applications, especially in the field of bio andgreen technologies. This study investigates the biodegradation potential of cotton membranesmodified with TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl) radical and citric acid (CA),with the aim of improving their properties and facilitating environmentally friendly disposal.TEMPO radicals, in conjunction with the crosslinker citric acid, are incorporated into thecellulose structure through a novel modification process. The citric acid component acted as aplasticizer, increasing the amorphous parts of the cellulose and promoting enzymatic attack.The TEMPO radical, with its nitroxyl group, contributed to the oxidation of cellulose, furtherfacilitating biodegradation.The biodegradation aspect of these modified membranes was investigated incontrolled environmental conditions (Soil Burial test), simulating natural scenarios (humidity,influence of enzymes, and bacteria). Biodegradation parameters such as weight loss,structural changes, and degradation kinetics were examined during 90 days. Characterizationof the structure was performed using FTIR and SEM methods.Our findings suggest that cellulosic membranes possess complete (100%)biodegradability after 70 days compared to unmodified membranes. Obtained result shedlight on the potential of membranes modified in this way as sustainable and biodegradablealternatives in various applications. The results emphasize their ecological nature and abilityto reduce environmental stress. Such cellulose-based materials promise a much greener futurein biotechnology, healthcare, and environmental protection.

AB  - Oxidized cotton linters, TOCell, were used as an adsorbent or derived membrane there from by linterscross-linking with citric acid. The adsorption/desorption study of Pb2+, methylene blue (MB), and crystalviolet (CV) removal, was performed. Adsorption data fitting, obtained using the Langmuir model, gave116 mg g 1 (Pb2+), 179 mg g 1 (MB) and 482 mg g 1 (CV) at 25 ℃ for TOCell linters, while 101 mg g 1(Pb2+), 165 mg g 1 (MB) and 426 mg g 1 (CV) for TOCell membrane. After desorption dyes were subjectedto photocatalytic degradation while lead was transformed into stable lead phthalate (LP), and furtherused as filler in composites based on unsaturated polyester resins (UPR). UPR was synthesized fromwaste polyethylene terephthalate (PET). Structural characterization was performed using FTIR, SEM,and NMR methods. Composites loaded with acryloyl modified kraft lignin (A-KfL) and/or LP was testedfor tensile strength, Vickers microhardness, and fire resistance (UL-94 V method). The best mechanicaland fireproofing properties were obtained at 15 wt.% A-KfL and 40 wt.% Al(OH)3 addition. The resultsof the toxicity leaching test (TCLP) confirmed the environmentally safe stabilization of desorbed pollutantin the UPR matrix. Application of environmentally friendly membranes, susceptible to easy biodegradation, had low negative effects to the environment.

AB  - Styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) rubber blends with tetramethyl thiuram disulfide (TMTD) and tetramethyl thiuram monosulfide (TMTS) accelerators and environmentally friendly plasticizers, obtained from PET recycling and biobased resources (LA/PG/PET/EG/LA), were prepared. The mechanical properties of the obtained rubber products were tested and compared with those of commercial dioctyl terephthalate (DOTP). TMTS was prepared by simple and efficient one-pot synthesis from dimethylamine, carbon disulfide, potassium cyanide, and ammonium chloride as catalysts in recycled isopropanol/water azeotrope as solvent. In a comparative study, methoxide, ethoxide, iodide, and amide ions were also used. The two-step reaction mechanism of TMTS synthesis involves the oxidation of the amine salt of dimethyldithiocarbamic acid to TMTD by hydrogen peroxide and sulfur elimination from the TMTD disulfide bond. Potassium cyanide appears to be the most efficient nucleophile. The simplicity of operation, mild reaction conditions, solvent recycling, high yields, and applicability to the industrial level are the advantages of this process. Shore hardness, tensile strength, and compression test results of vulcanized blends before and after aging showed similar properties for both accelerators, while somewhat better results were obtained with LA/PG/PET/EG/LA plasticizer.

AB  - Multifunctional lignin bio-based adsorbent, b-LMS, was obtained via inverse copolymerization in the suspension of acryloyl modified kraft lignin (KfL-AA) and bio-based trimethylolpropane triacrylate (bio-TMPTA). Morphological and structural characterization of KfL-AA and b-LMS was performed using BET, FTIR, Raman, NMR, TGA, SEM, and XPS techniques. The b-LMS microspheres with 253 ± 42 μm diameters, 69.4 m2 g−1 surface area, and 59% porosity efficiently adsorb Malachite Green (MG), Tartrazine (T), and Methyl Red (MR) dye. The influence of pH, pollutant concentration, temperature, and time on the removal efficiency was studied in a batch mode. Favorable and spontaneous processes with high adsorption capacities e.g. 116.8 mg g−1 for MG, 86.8 mg g−1 for T, and 68.6 mg g−1 for MR indicate the significant adsorptive potential of b-LMS. Results from diffusional and single mass transfer resistance studies indicate that pore diffusion is a rate-limiting step. Theoretical calculations confirmed a higher affinity of b-LMS to cationic dye MG compared with an anionic and neutral one, i.e. T and MR, respectively. The data fitting from a flow system, using semi-empirical equations and Pore Surface Diffusion Modelling (PSDM) provided breakthrough point determination. The results from the desorption and competitive adsorption study proved the exceptional performance of b-LMS. Moreover, sulfation of b-LMS, i.e.production of b-LMS-OSO3H, introduced high-affinity sulfate groups with respect to cationic dye and cations. Developed methodology implements the principle of sustainable development and offers concept whose results contribute to the minimization of environmental pollution.

AB  - In this study, the structure, morphology and composition of the synthesized magnetite/3D-printed wollastonite (3D_W/M) composite were characterized, and its adsorption performance with respect to As(V) and Cr(VI) were studied. Magnetite (MG) modified 3D printed wollastonite was obtained by two step procedure: modification of 3D_W with 3-aminoproylsilane (APTES) followed by controlled magnetite (MG) deposition to obtain 3D_W/M adsorbent. The structure/properties of 3D_W/M were confirmed by applying FTIR, XRD, TGD/DTA, and SEM analysis. The adsorption properties of hybrid adsorbents were carried out for As(V) and Cr(VI) removal-one relative to the initial pH value, the adsorbent mass, the temperature, and the adsorption time. Time-dependent adsorption study was best described by pseudo-second order equation, while Weber Morris analysis showed that intraparticle diffusion controled diffusional transport. Similar activation energy, 17.44 and 14.49 kJ•mol-1 for adsorption As(V) and Cr(VI) on 3D_W/M, respectively, indicated main contribution of physical adsorption. Determination of adsorption parameters was performed by applying different adsorption isotherm models, and the best fit was obtained using Freundlich model. The adsorption capacity of 24.16 and 29.6 mg g-1 for As(V) and Cr(VI) at 2o C, Co = 5.5 and 5.3 mg L-1, respectively, were obtained. Thermodynamic study indicated favourable process at a higher temperature. Preliminary fixed-bed column study and results fitting with Bohart-Adams, Yoon-Nelson, Thomas, and Modified dose-response model showed good agreement with results from the batch study.

AB  - Silica particles were produced form rice husk and used as reinforcement in
the polymer matrix. The obtained silica particles' surfaces were modified with
layered double hydroxides, which enabled better reinforcement in the PMMA matrix.
Coprecipitation was used to synthetize Fe Al layered double hydroxides (LDH) with
a Fe:Al cation content of 3:1 and an FeAl-LDH: silica ratio of 1:1. X-ray diffraction,
Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy
with EDS were used to characterize the synthesized particles. The prepared particle
amounts in the PMMA matrix were 1, 3, and 5 wt. %. The purpose of this study was
to see if the obtained SiO2 particles, as well as their modification with FeAl-LDH,
had any effect on the mechanical properties of polymer composite materials. The
mechanical characterization of obtained composites was done using Vickers
microindentation tests and impact testing. The Vickers micro-hardness test showed
that the addition of reinforcement increases the hardness of the composite. When
compared to the matrix, the toughness of the composite material with a higher
content of particles (5 wt. %) in the energy absorbed in this impact test was three
times higher.

The synthesized SiO2 particles were characterized using X-ray diffraction, Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy with EDS. In a PMMA matrix, prepared SiO2 particles in amounts of 1, 3, and 5 wt.% were used as reinforcing agents. The goal of this research was to see if SiO2 particles had any effect on the mechanical properties of polymer composite materials. The morphology of the composites was examined using a field emission scanning electron microscope (FE-SEM). Vickers microindentation hardness and impact testing were used to determine the mechanical properties of the obtained composites. The indentation creep’s behavior of a polymethylmetacrylate (PMMA) composite material with varying amounts of nanoparticles (SiO2) was investigated and analyzed.
