Stability of gold complex based on mercaptotriazole in acid and neutral media
(Bulgarian Academy of Sciences, 2018)
Stability of the gold complex based on mercaptotriazole in two acid electrolytes with different pH values and in a neutral medium was investigated in this work. Investigation was performed by visual monitoring and ...
In situ synthesis of Cu/Cu2O nanoparticles on the TEMPO oxidized cotton fabrics
(Springer, Dordrecht, 2018)
In situ synthesis of Cu/Cu2O nanoparticles on the cotton fabric discussed in this study relies on adsorption of Cu2+-ions by carboxylate groups generated through the TEMPO-mediated oxidation of cellulose and their subsequent ...
Development of material with strong antimicrobial activity by high pressure CO2 impregnation of polyamide nanofibers with thymol
(Elsevier Sci Ltd, Oxford, 2018)
This study discusses the potential of high pressure (supercritical and liquid) CO2 impregnation to load electrospun polyamide nanofibers with thymol as an antimicrobial agent. The influence of selected pressures and ...
Achieving high antimicrobial activity: Composite alginate hydrogel beads releasing activated charcoal with an immobilized active agent
(Elsevier Sci Ltd, Oxford, 2018)
New composites based on Ca-alginate hydrogels were produced that release activated charcoal (AC) particles with adsorbed povidone iodine (PVP-I) as a model antimicrobial substance in a physiological-like environment. ...
Antibacterial activity of Cu-based nanoparticles synthesized on the cotton fabrics modified with polycarboxylic acids
(Elsevier Sci Ltd, Oxford, 2018)
The fabrication of antimicrobial textile nanocomposite by in situ synthesis of Cu-based nanoparticles on cotton fabrics modified with different polycarboxylic acids was discussed in this study. In order to evaluate the ...
Cefazolin-loaded polycaprolactone fibers produced via different electrospinning methods: Characterization, drug release and antibacterial effect
(Elsevier, Amsterdam, 2018)
Antibiotic containing polycaprolactone (PCL) fibers were produced by using three electrospinning methods: blend, emulsion and co-axial electrospinning (labeled as S1, S2 and S3, respectively). The profiles of drug release ...
Possibility of L-(+)-lactic acid fermentation using malting, brewing, and oil production by-products
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Industrial by-products such as brewer's spent grain (BSG) hydrolysate, malt rootlets extract (MRE) and soybean meal extract (SME) were used for L-(+) lactic acid (LA) production by a pure L rhamnosus ATCC 7469 strain. The ...
Processing and Characterisation of Hybrid Aramid Fabrics Reinforced with Cross-linked Electrospun PVB Composite Nanofibres
(Korean Fiber Soc, Seoul, 2018)
The aim of this study was to fabricate a new kind of hybrid fabric composites with the cross-linked electrospun poly(vinyl butyral) (PVB) composite nanofibres. The experiments were performed with the 10 wt.% PVB/ethanol ...
Optimization of Al2O3 particle modification and UHMWPE fiber oxidation of EVA based hybrid composites: Compatibility, morphological and mechanical properties
(Elsevier Sci Ltd, Oxford, 2018)
Ultra-high molecular weight polyethylene (UHMWPE, PE)/oxidized PE (ox-PE) fibers and alumina reinforcement were used in preparation of poly (ethylene-co-vinyl acetate) (EVA)/hydrolyzed EVA (EVAOH) based composites. Different ...
Physico-chemical evaluation of hydrophobically modified pectin derivatives: Step toward application
(Elsevier, Amsterdam, 2018)
Present study reports synthesis and physico-chemical evaluation of hydrophobically modified pectin derivatives, obtained by reacting of pectin with di-acyl chlorides (glutaryl and sebacoyl chloride). Depending on length ...
