In this work, we provide a facile path for the preparation of wound dressing materials with improved characteristics based on biocompatible chitosan and poly(vinyl alcohol) hydrogels with embedded silver nanoparticles ...
Enzyme production by solid-state fermentation on soybean meal: A comparative study of conventional and ultrasound-assisted extraction methods
(Wiley, Hoboken, 2019)
Protease, cellulase, and alpha-amylase producing Bacillus subtilis strain was cultivated by solid-state fermentation technique using soybean meal as a substrate. The aim of the present study was to establish a highly ...
Adsorption performances of branched aminated waste polyacrylonitrile fibers: experimental versus modelling study
(Desalination Publ, Hopkinton, 2019)
Synthesis of branched aminated waste polyacrylonitrile (PAN) fibers, realized in a three addition/amidation successive steps, was performed in order to obtain AS3-PAN adsorbent. Influence of various operating parameters ...
Doping of TiO2 nanotubes with nitrogen by annealing in ammonia for visible light activation: Influence of pre- and post-annealing in air
(Elsevier Science Sa, Lausanne, 2019)
The similar to 60 nm wide and similar to 2 mu m long TiO2 nanotubes were obtained by anodization of Ti films sputtered on F-doped tin oxide glass. For N-doping the samples were annealed in ammonia atmosphere. The effect ...

(Taylor & Francis Ltd, Abingdon, 2019)
Adhesion behavior between the composite films, consisting of UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA (triethylene glycol dimethacrylate) as a matrix and the ferrous oxide doped alumina particles, Al2O3 ...
Effects of oxidized/treated non-metallic fillers obtained from waste printed circuit boards on mechanical properties and shrinkage of unsaturated polyester-based composites
(Wiley, Hoboken, 2019)
The investigation of the influence of acid/base treatment and addition level of non-metallic fractions (NMFs), obtained by processing of printed circuit boards, on the mechanical properties and shrinkage of unsaturated ...
Impact of Alumina Particles on the Morphology and Mechanics of Hybrid Wood Plastic Composite Materials
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
Hybrid composite panels of Wood-Plastic Composites (WPC) consisting of wood and poly (methyl methacrylate) (PMMA) were reinforced with alumina particles and made by "hot pressing" method. Alumina-based particles were made ...
Novel nano-composite hydrogels with honey effective against multi-resistant clinical strains of Acinetobacter baumannii and Pseudomonas aeruginosa
(Springer, New York, 2019)
Novel alginate hydrogels with silver nanoparticles (AgNPs) and honey components were produced with the aim to target multidrug-resistant bacterial strains causing nosocomial wound infections. AgNP synthesis was optimized ...
