Microplastics in the environment occur different sizes and shapes are made of various polymers. Therefore, they also considerably differ their properties ecotoxicity. However, majority microplastics research uses pre-made spherical microplastics, which practically do not exist environment. Our work focused on a comprehensive study six types microplastic that were prepared to simulate common found All where chemically physically characterized using Fourier-transform infrared spectroscopy,...
The production of sustainable and effective flame retardant (FR) polyamide 6 (PA6) fibrous materials requires the establishment a novel approach for 6/FR nanodispersed systems. This research work explores influence three different flame-retardant bridged 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) derivatives on comprehensive properties in situ produced PA6/FR To this end, water-catalyzed ring-opening polymerization ε-caprolactam was conducted presence DOPO derivatives, e.g.,...
In the present study, a Bi2WO6/ZnWO4 photocatalyst was successfully constructed by modified hydrothermal synthesis method with different molar concentrations of Bi2WO6 respect to ZnWO4. The variation in changed photocatalytic properties catalyst. synthesized characterized various techniques decipher its structural and spectral properties. interaction Bi2+ ionic charge carriers many-body effects cause band gap narrow Bi2WO6/ZnWO4, as shown PL analysis. decrease energies (Eg) from 4.7 eV...
Multifunctional properties are crucial for the production of high-quality technical textiles. In this study, a cotton fabric with simultaneously superior UV-protection, self-sterilisation, photocatalytic self-cleaning and flame retardant was produced using sol–gel/hydrothermal process, in which titanium(IV) isopropoxide (TTIP) as titanium dioxide (TiO2) precursor combined first time mixtures organofunctional trialkoxysiloxanes, i.e., 3-(trihydroxysilyl)propyl methylphosphonate (TPMP) P-based...
Complexes with mixed ligands [Cu(N-N)2(pmtp)](ClO4)2 ((1) N-N: 2,2′-bipyridine; (2) L: 1,10-phenanthroline and pmpt: 5-phenyl-7-methyl-1,2,4-triazolo[1,5-a]pyrimidine) were synthesized structurally biologically characterized. Compound (1) crystallizes into space group Pa in P-1. Both complexes display an intermediate stereochemistry between the two five-coordinated ones. The biological tests indicated that compounds exhibited superoxide scavenging capacity, intercalative DNA properties,...
Herein, we present a novel approach to the development of multifunctional, UV-protective, photocatalytic, antimicrobial and flame-retardant nanocomposite fabric surface. Using sol–gel/hydrothermal approach, phosphorus-based 3-(trihydroxysilyl)propyl methylphosphonate (TPMP) in combination with Ag-doped TiO2 was applied surface cotton fibers for first time, using an aqueous AgNO3 solution as dopant. The modified fabrics were characterized by Fourier transform infrared spectroscopy (FT-IR),...
Studies of the production fiber-forming polyamide 6 (PA6)/graphene composite material and melt-spun textile fibers are scarce, but research to date reveals that achieving high dispersion state graphene is main challenge nanocomposite production. Considering significant progress made in industrial mass nanoplatelets (GnPs), this study explored feasibility PA6/GnPs using commercially available few-layer GnPs. To aim, GnPs were pre-dispersed molten ε-caprolactam at concentrations equal 1 2 wt...
Self-healing anticorrosion composite coatings containing isophorone diisocyanate-loaded polyurethane microcapsules were developed, and comprehensive research on prepolymer synthesis, as well functional preparation characterization, was performed. The influence of the type concentration stabilizing agent used in synthesis procedure properties studied detail. For this purpose, three different prepolymers prepared from toluene-2,4-diisocyanate (TDI) either glycerol, 1,4-butanediol, or...
Alkaline earth aluminates with the overall nominal compositions Mg0.5Sr0.5Al2O4 (MSA), Ca0.5Mg0.5Al2O4 (CMA) and Ca0.5Sr0.5Al2O4 (CSA) doped 0.5 mol% of Eu2+ 0.25 Nd3+ ions were obtained by a modified aqueous sol-gel method annealed in reducing atmosphere at 900, 1000, 1100 1300 °C.

When wood is thermally modified, several chemical reactions take place that change the and physical properties of wood. These changes correlate with degree modification, which mostly a function temperature duration consequently mass loss during this process.
