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 fromrice husk. The structural and morphological properties of the obtained particles, b-UPR, as well ascomposites, were characterized by Fourier-transform infrared spectroscopy (FTIR), nuclear magneticresonance spectroscopy (NMR), scanning electron microscopy (SEM), and transmission electronmicroscopy (TEM) techniques. The study of the influence of biosilica modification on the mechanicalproperties of composites was supported by hardness modeling. Improvement of the tensile strengthof 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 appliedto 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).The grinded artificially aged b-UPR composites were used as filler in c-UPR for the production of atable top layer with outstanding mechanical properties, i.e., impact resistance and microhardness, aswell as fire resistance rated in the V-0 category according to the UL-94 test. Developing sustainablecomposites that are chemically synthesized from renewable sources is important from the aspect ofpreserving the environment and existing resources as well as the extending their life cycle.

AB  - The morphological properties and adsorption potential of lignin-based porous
microspheres (LgMS) for heavy metals ions were investigated. LgMS were produced via
suspension copolymerization of unmodified or acryloyl modified kraft lignin with amine
(polyethylene imine - PEI) or acrylate (trimethylolpropanetriacrylate - TMPTA) functional
polymers. Structural and morphological characterization of LgMS was performed using
FTIR, BET, and SEM techniques. Copolymerization of the unmodified lignin and PEI, using
epoxy chloropropane cross-linker, provided highly porous LgMS, with 800 ± 80 μm
diameter, 7.68 m2g−1 surface area and 7.7 mmol g−1 of terminal amino groups. The LgMS
produced by copolymerization of the acryloyl functionalized lignin and TMPTA provided a
decrease in LgMS diameter (253 ± 42 μm), while surface area and porosity increase, 69.4 m2
g-1and 59%, respectively. The effect of acryloyl functionalization of kraft lignin on the
LgMS adsorption capacity for Ni2+ ions was also studied in a comparative study. The results
showed that final adsorption performances of LgMS were affected by the key factors
including lignin functionality and the LgMS synthesis condition. Lower adsorption capacity
of 22.6 mg g-1 for Ni2+ was observed for acryloyl LgMS due to lower affinity for formation
electrostatic interactions of Ni2+ ions with phenol/hydroxyl groups responsible for
adsorption. Opposite was found for amino LgMS where 49.4 mg g-1was achieved. However,
this study indicated that removal of heavy metal ions from wastewater can be realized
through the application of eco-friendly lignin-based porous microspheres.

AB  - The novel lignin-based microspheres (LMS-DEGDMA) were produced through a two-step modification procedure consisting of kraft lignin (KL) modification with acrylic acid synthesized from fructose; and suspension and copolymerization of acrylic acid modified KL (KL-A) with diethylene glycol dimethacrylate (DEGDMA). The applied procedure provided LMS-DEGDMA microspheres in the size range of 50-90 μm with specific surface area of 39 m2/g, porosity ϵp 62, pore diameters of 4-20 nm and total pore volume of 0.14 cm3/g. Immobilization of laccase from Myceliophthora thermophilia expressed in Aspergillus oryzae (Novozyme® 51003) on LMS-DEGDMA was explored. By optimization of the immobilization process, it was demonstrated that laccase immobilization on LMS-DEGDMA exhibited the best results (protein immobilization yield of 70 %, activity yield of 27 %, and catalytic activity of 262 IU/g of support) when the immobilization was carried out at pH 5.0 and 100 mg of offered protein per g support during 1 h. Additionally, the LMS-DEGDMA-laccase preparation showed efficiency (>80 %, 5-7 cycles) in decolorization of anthraquinone dyes (Lanaset® violet B, Lanaset® blue 2 R and C.I. Acid Green 40) and their mixture. In case of Lanaset® violet B, LMS-DEGDMA improved laccase's kinetics characteristics (90 % over 24 h) along with operational stability (> 63 % catalytic activity, 7 cycles).

AB  - The presented research focused on the metallization of polyester, cotton, and polyamide 6.6 fabrics using the silver conductive complex to allow electric conductivity through the fabric's surface and enhance the fabric's mechanical properties. The method used for the metallization of studied fabrics does not require the use of expensive toxic chemicals or electricity, making the process more economically acceptable. The signal attenuation was measured in frequency ranges of 1–4 and 5–12 GHz. After five cycles of metallization, the polyester fabric has higher EMI effectiveness, in a lower range was 45.44 and 57.25 dB. X-ray powder diffractometry (XRD) and infrared spectroscopy with Fourier transform infrared spectrophotometry (FT-IR) characterize the modified tissues. Scanning electron microscopy coupled with energy-dispersion spectroscopy (SEM-EDS) was used to determine layers' morphology and elemental composition. Also, the water and air permeability of modified textiles was determined.

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  - Electromagnetic interference (EMI) has become a widespread modern environmental pollutant. There is an essential need for practical and applicable materials for its attenuation. Therefore, the presented research has focused on metallization of carbon fabric using the silver conductive complex solution to enhance the surface conductivity and mechanical properties of the fabric. With this amplification and improving the mentioned characteristics, lightweight and flexible modified carbon fibers can be applied in many environments. The modification has been performed in three steps: the silver conductive complex synthesis, carbon fabric immersion into a silver complex solution, treating with temperature for silver deposition by annealing. The method used for the metallization of carbon fabrics surface does not require expensive and toxic chemicals or electricity, making the process more ecologically and economically acceptable. One of the advantages of using the method for surface modification is the possibility of usage for other materials, not only for textiles and foils. The examination of the surface structure, electrical, EMI shielding characteristics, and mechanical properties of carbon fabrics modified by silver deposition contributes to the determination of multifunctional properties of materials. Also, the dependence on the improvement of multispectral electromagnetic interference shielding effectiveness (EMI SE) characteristics and mechanical properties of materials on the number of cycles has been determined. The most effective material was carbon fabric modified by five cycles, and average attenuation at an L and S bands was 49.67 dB, and a part of C and full X band was 51.07 dB, caused by better coverage by silver particles, increased density and porosity of deposited layer. Increasing the number of silver deposition cycles improves the physical properties of the modified carbon fabrics, where after five cycles the highest maximum force has been measured (2.26 kN). The material's morphology was studied by scanning electron microscopy with Energy-Dispersive X-ray Spectroscopy. The crystallographic phases of sintered particles were determined by X-ray diffraction. The crystallographic phases of sintered particles were determined by X-ray diffraction.

AB  - Highly effective lignin-based microspheres were prepared by inverse copolymerization of lignin (kraft) from suspension, with poly(ethylene imine) and amino-functionalized magnetite nanoparticles (A-LMS_Fe3O4) or manganese(IV)oxide nanoparticles (A-LMS_MnO2). The XRD, FTIR, SEM, BET, TEM techniques, including the porosity determination, were performed to analyze morphological and structural properties of synthesized microspheres. The effect of pH, the adsorbent dosage, temperature and contact duration on a batch-mode adsorption efficiency of arsenate and chromate (oxy)anions removal was tested. Spontaneous adsorption was found to be feasible, reaching the adsorption capacities of Cr(VI) (62.9 mg g-1), As(V) (47.8 mg g-1) by A-LMS_Fe3O4, and of Cr(VI) (73.9 mg g-1), As(V) (62.5 mg g-1) using A-LMS_MnO2 adsorbent. Fast removal rates were confirmed via kinetic study, using pseudo-second order, the Weber-Morris and the single resistance mass-transfer model, with a limiting step of the diffusion transport through pores. The correlation of fixed-bed-column results with Bohart-Adams, Thomas, Yoon-Nelson and Dose Response models displayed that breakthrough behavior was influenced by flow rate and the inlet concentration. Significant potential of produced bio-adsorbent is further confirmed by the pore surface diffusion modeling, desorption study and adsorption from multi-component system using artificial water.

AB  - In this study, silicate nanofillers; dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite; were synthesized using four different methods and incorporated into the epoxy resin to improve its mechanical properties. Characterization of the newly synthesized nanofillers was performed using Fourier-transformation infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The purpose of this study was to analyze newly developed composite materials reinforced with silicate nanoparticles utilizing tensile testing and a full-field non-contact 3D Digital Image Correlation (DIC) method. Analysis of deformation and displacement fields gives precise material behavior during testing. Testing results allowed a more reliable assessment of the structural integrity of epoxy composite materials reinforced using different silicate nanofillers. It was concluded that the addition of 3% of dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite lead to the increasement of tensile strength up to 31.5%, 29.0%, 27.5%, and 23.5% in comparison with neat epoxy, respectively. In order to offer more trustworthy information about the viscoelastic behavior of neat epoxy and composites, a dynamic mechanical analysis (DMA) was also performed and rheological measurements of uncured epoxy matrix and epoxy suspensions were obtained.

AB  - Two types of polymer waste materials, poly(ethylene terephthalate) (PET) and polycarbonate based Colombian Resin (CR-39), were used for the designing of fully recycled composite materials. Waste PET was employed for the synthesis of thermoset unsaturated polyester resin (UPR), while CR-39 was used as reinforcement in the UPR matrix. Prior to mixing, CR-39 particles were subjected to oxidation and chemical activation using acids/base and ethanol amine, respectively. The effect of the modifier type and variable loading of the activated CR-39 particles on mechanical and dynamic-mechanical properties of the corresponding composites was investigated. The greatest improvement in the tensile and flexural strength of UPR resin was achieved with the composite containing 0.5 wt% of amine activated filler particles, 96.0% and 62.2%, respectively. The Arrhenius equation was used to calculate the activation energy for glass transition from dynamic mechanical properties measured at various frequencies. The activation energy of the main transition for UPR resin and composites were calculated to be 173 and 350 kJ center dot mol(-1) indicating that reinforcement results in an increase in the energy barrier to macromolecules viscoelastic relaxation. In addition, erosion resistance was studied during exposure of samples to cavitation tests. According to the obtained results, these materials can be applied in construction and mining industry.

AB  - The para-aramid fibres (Kevlar, Twaron, Kolon) are high performance polymeric fibres characterized by their high tenacity, strength to weight ratio and impact resistance. They are used for the soft body armour structures in ballistics and for the manufacture of parts in aerospace and automotive industry.
In this study, the specimens were made from the two-layered Kolon fabrics impregnated with epoxy resin where some silicon carbide (SiC) microparticles or SiC nanofibres were added as reinforcement. These composite specimens
were fabricated by hot compression and curing of epoxy resin.
Despite their good mechanical strength it is a well-known fact that the mechanical properties of epoxy resins are affected by moisture absorption. The tensile and impact properties of the untreated specimens were compared with the ones that underwent water absorption in the duration of 72h (immersion or humidity) followed by desorption. The immersion of the specimens in water and the exposure to high humidity (70%) were completed in accordance with the ISO 62 standard while the tensile test was performed according to the ASTM D 3039 standard. Furthermore, the tensile test simulation of the Kolon/epoxy composite by using software Abaqus® was accomplished.
For the determination of the absorbed impact energy and the impact toughness of the composite specimens, an impact test was performed by using the Charpy impact pendulum in accordance with the ASTM D5942 standard.

AB  - In-depth kinetic and column adsorption study for diclofenac, DCF, heavy-metal and oxyanions adsorption on highly effective amino-functionalized lignin-based microsphere adsorbent (A-LMS) is examined. The A-LMS was synthesized via inverse suspension copolymerization of industrial kraft lignin with the amino containing grafting-agent (polyethylene imine), and an epoxy chloropropane cross-linker. The batch adsorption results indicated process spontaneity and feasibility of a high removal capacity: DCF(151.13) >>Cd2+(74.84)>Cr(VI)(54.20)>As(V)(53.12)>Ni2+(49.42 mg g(-1)). The quantum chemical calculated interaction energies reveal stabilization of the A-LMS/DCF complex through the electrostatics and van der Waals interactions. The results from the pseudo-second order and Weber-Morris fitting indicate a fast removal rate; thus, column tests were undertaken. The single resistance mass transfer model, i.e. the mass transfer (kfa) and diffusion coefficient (Deff), shows pore diffusional transport as a rate limiting step. The fitting of the fixed bed column data with empirical models demonstrates the influences of flow rate and adsorbate inlet concentration on the breakthrough behavior. Pore surface diffusion modeling (PSDM) expresses mass transport under applied hydraulic loading rates, calculated breakthrough point adsorption capacities: Cd2+(58.1)>Cr(VI)(54.1)>As(V)(50.9)>>Ni2+(42.9 mg g(-1))), without performing the experimentation on a full pilot-scale level, further confirms the high applicability of the A-LMS biobased adsorbent.

AB  - Expanded vermiculite (EV) was modified by deposition of different spinel ferrite composites on the outer surface of EV 2:1 layers in order to improve its adsorptive properties. Modifications were made by deposition of: magnetite, manganese ferrite, cobalt ferrite and chromium oxide/hematite. The characterization of modified materials was performed by: scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) methodology, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), magnetization measurements, as well as determination of cation exchange capacity (CEC) and pH point of zero charge (pHPZC). Obtained samples were used as adsorbents for Pb2+, Ni(2+)and Cd2+ ions from an aqueous solution in a batch system. Results showed that adsorption capacity was strongly dependent on physical and chemical changes induced by specific chemical modification. Hydrothermally produced manganese and cobalt ferrites caused significant surface changes and altered the interlayer cation balance. Among the others, EV-Mn/Co-ferrite(s) samples possessed the highest adsorption capacity towards Ni2+ (33.06 mg g(-1)), along with an increase of the CEC. Freundlich's adsorption isotherm model provided the best fit of obtained experimental data, while kinetic studies showed that the adsorption rate follows the pseudo second-order model, implying heterogeneous adsorbents surface. Thermodynamic and kinetic parameters indicated that the mechanism of cations removal efficacy was dominantly followed by the ion exchange. This study confirmed that doped ferrites, produced by solvothermal method, improve surface properties of EV and increase adsorption potentials towards heavy metals.

AB  - Multilayered composites based on aramid fabrics are widely used in impact protection. The objective of this study is creating a new kind of multiaxial aramid fabric composites with inorganic fullerene-like tungsten disulfide nanoparticles (IF-WS2) and single walled carbon nanotubes (SWCNT) used as nanoreinforcement to enhance the dynamic mechanical and anti-stabbing properties of the composites. The four composites of the Kolon fabric forms were impregnated with 10 wt.% poly(vinyl butyral) (PVB)/ethanol solution which contained different forms of IF-WS nanoparticles. The surfaces of IF-WS2 were coated with silane coupling agent (m-IF) and the SWCNT were oxidized (o-SWCNT) for the fabrication of the o-SWCNT/m-IF hybrid nanoparticles. The mechanical testing showed that the Kolon/PVB/o-SWCNT/m-IF sample produced nearly 62 % of improvement in the tensile strength and 51 % of improvement in the tensile energy absorption compared to the Kolon/PVB sample. Furthermore, the sample with the o-SWCNT/m-IF hybrid nanoparticles demonstrated 24 % of enhancement in the impact toughness and 48 % of improvement in the absorbed energy after knife penetration in comparison with the Kolon/PVB sample.

AB  - Para-aramid fibers (Kolon) are high performance polymeric fibers characterized by their high tenacity and impact resistance. They are used for the soft body armor structures in ballistics. In this study, the testing specimens were made from multilayered Kolon fabrics impregnated with epoxy resin where silicon carbide (SiC) microparticles or SiC nanofibers were added as reinforcement. The laminated composite samples were fabricated by hot compression and curing of epoxy resin. The tensile and impact strengths of the untreated specimens were compared with the ones that underwent water absorption in duration of 72 h (immersion or humidity) followed by desorption. The immersion of the specimens in water and exposure to high humidity (70%) were performed according to the ISO 62 standard while the tensile test was carried out in accordance with the ASTM D 3039 standard. In the end, the tensile test simulation of the laminated composite by using software Abaqus (R) was accomplished.

AB  - In order to examine the possibility to improve its camouflage properties standard cotton fabric with camouflage print was impregnated with poly(vinyl butyral), PVB and fullerene-like nanoparticles of tungsten disulfide, PVB/IF-WS2. FTIR analysis excluded any possible chemical interaction of IF-WS2 with PVB and the fabric. The camouflage behavior of the impregnated fabric has been examined firstly in the VIS part of the spectrum. Diffuse reflection, specular gloss and color coordinates were measured for three different shades (black, brown and dark green). Thermal imaging was applied to examine the camouflage abilities of this impregnation in IR part of the spectrum. The obtained results show that PVB/IF-WS2 impregnation system induced enhacement of the materials camouflage properties, i.e. that IF-WS2 have a positive effect on spectrophotometric characteristics of the fabric.

AB  - An optimized method is presented to make magnetite (MG) modified cellulose membrane (Cell-MG) from 3-aminopropyltriethoxysilane and diethylenetriaminepentaacetic acid dianhydride functionalized waste cell fibers; (Cell-NH(2)and Cell-DTPA), and amino-modified diatomite. Functionalized Cell-NH2, Cell-DTPA fibers, and diatomite were structurally and morphologically characterized using FT-IR, Raman, and FE-SEM analysis. Amino and carboxyl group content was determined via standard volumetric methods. Response surface method was applied to rationalize the number of experiments related to Cell-MG synthesis and heavy metal ions column adsorption experiments. The effects of pH, contact time, temperature, and initial concentration of pollutants on adsorption and kinetics were studied in a batch, while initial concentration and flow rate were studied in a flow system. The calculated capacities of 88.2, 100.7, 95.8 and 78.2 mg g(-1)for Ni2+, Pb2+, Cr(VI) and As(V) ions, respectively, were obtained from Langmuir model fitting. Intra-particle diffusion as a rate-limiting step was evaluated from pseudo-second-order and Weber-Morris model fitting. Thermodynamic parameters indicated spontaneous and low endothermic processes. The results from reusability study, wastewater purification and fixed-bed column study proved the high applicability of Cell-MG. Additionally, high removal capacity of four dyes together with density functional theory and molecular interaction fields, help in the establishment of relation between the adsorption performances and contribution of non-specific and specific interactions at adsorbate/adsorbent interface.

AB  - In this work, the optimization of synthesis of terpolymer monolith based on glycidyl methacrylate (GMA), ethylene glycol dimethacrylate (EGDMA) and additional cross-linkers: trimethylolpropanetriacrylate (TMPTA) or triethylene glycol dimethacrylate (TEGDMA) was performed. Moreover, novel vinyl functionalized cross-linkable polymers: ethanolamine (EA)/methacryloyl (MAC) modified poly (methyl methacrylate) (PMMA), and hydrolyzed poly (ethylene-co-vinyl acetate) copolymer (EVOH) modified with MAC either directly or via ethyl malonyl chloride/EA bridging group (m-EVA) were used as cross-linkable polymer to improve mechanical/elastic properties of the obtained monoliths. Optimization procedure, performed applying response surface methodology (RSM), was focused on the production of materials with improved dimensional stability/integrity and porosity with abundance of epoxide groups capable for immobilization of lipase from Candida rugosa (CRL). Structural characterization of the synthesized monoliths was determined using FTIR, Raman and H-1 NMR spectroscopies, while morphology/porosity was determined by SEM technique and image analysis; and mechanical properties by diametral compression testing. The most potential monolith containing m-EVA polymeric cross-linker, i.e. GMA/EGDMA/TEGDMA/m-EVA monolith, was used as CRL carrier in a two-step immobilization process. Enzyme loading and the activity of obtained preparations for various initial enzyme concentrations were monitored after 4 and 48 h of immobilization. The resulting catalysts show high potency in biocatalytic reactions with the highest percentage of retained initial lipase activity of 64.5%.

AB  - Industrial/technological growth is directly connected with environmental pollution, but its influence can be minimized through pollution abatement approaches such as the treatment of industrial wastewater. In this study, novel porous amine-functionalized silicate minerals, specifically, cordierite was investigated for the removal of toxic heavy metals from industrial wastewaters. Cordierite supports were synthesized by mixing MgO, Al2O3, and SiO2 powders in 2:2:5 molar ratios, and mechanically activated via ball milling in ethanol for 10, 40, or 80 min. Pellets were sintered by heating in air at 20 degrees C min(-1) to 1,350 degrees C, for 2 h. Porous supports were produced by coarsely crushing the sintered pellets and mixing the crushed and sieved cordierite powder with 20 wt.% of a pore-forming agent, either nanocellulose or yeast. The resulting pellets were sintered by heating at 5 degrees C min(-1) to 700 degrees C in air. The synthetic cordierite support was modified by treatment in poly-ethylenimine. Activated supports were then tested for the removal of Ni2+ and Cd2+ ions. The phase composition of the cordierite supports was analyzed by the X-ray diffraction, Fourier-transform infrared spectroscopy, and scanning electron microscopy. Analysis of adsorption isotherms, kinetics, and thermodynamic parameters indicated that adsorption was a spontaneous, endothermic process with a maximum adsorption capacity of 36 mg g(-1) for Cd2+ and 43 mg g(-1) for Ni2+. This work has shed light on the mechanism of heavy metal removal from the aquatic medium using the novel hybrid functionalized cordierite-based ceramic.
