Moisture absorption capacity of polyamide 6,6 fabrics surface functionalised by chitosan-based hydrogel finishes
(Elsevier Science Sa, Lausanne, 2011)
The present study aims at investigating the moisture absorption capacity of polyamide 6,6 fabrics when their surface is functionalised by chitosan-based hydrogels. For the finishing procedure, bulk hydrogels of chitosan ...
The phase equilibrium of triglycerides and ethanol at high pressure and temperature: The influence on kinetics of ethanolysis
(Elsevier Science Bv, Amsterdam, 2012)
Biodiesel synthesis by ethanolysis of triglycerides conducted under high pressure and at elevated temperature can lead to high levels of conversion and biodiesel yield over short reaction time. The vapour-liquid or ...
Multifunctional PES fabrics modified with colloidal Ag and TiO2 nanoparticles
(Wiley, Hoboken, 2011)
This study is aimed to highlight the possibility of engineering the multifunctional textile nanocomposite material based on the polyester (PES) fabric modified with colloidal Ag and TiO2 nanoparticles (NPs). The effects ...
Kinetic models of swelling and thermal stability of silver/poly(vinyl alcohol)/chitosan/graphene hydrogels
(Korean Society of Industrial Engineering Chemistry, 2019)
Silver nanoparticles (AgNPs) were synthesized by in situ electrochemical reduction of Ag+ ions in poly(vinyl alcohol)/chitosan/graphene (PVA/CHI/Gr) hydrogel matrices with different concentrations of chitosan. The ...
Synthesis and characterization of porous tungsten carbide with added tungsten silicides
(Elsevier Sci Ltd, Oxford, 2018)
Porous materials made of commercial tungsten carbide (WC) with the addition of thermally obtained tungsten silicides (WSi2 and W5Si3) were made. The main research's contribution is firstly finding optimal conditions for ...
Exchange-Bias and Grain-Surface Relaxations in Nanostructured NiO/Ni Induced by a Particle Size Reduction
(Amer Chemical Soc, Washington, 2012)
Transition-metal-oxide/transition-metal nanocomposites, such as NiO/Ni, FeO/Fe, and CoO/Co, have been the subject of much recent investigation (i) because of their potential applications and (ii) because they are good model ...
Experimental investigation and thermodynamic prediction of the Au-Cu-Sb phase diagram
(Elsevier Science Sa, Lausanne, 2011)
Phase diagram of the ternary Au-Cu-Sb system was investigated experimentally by DTA and SEM-EDS methods and analytically by CALPHAD method. The liquids projection, invariant equilibrium, several vertical sections and ...
Encapsulation of resveratrol into Ca-alginate submicron particles
(Elsevier Sci Ltd, Oxford, 2015)
Resveratrol-loaded alginate submicron particles were prepared by emulsification followed by external gelation. Scanning electron microscopy analysis of the air-dried and freeze-dried submicron particles demonstrated their ...
Adsorption Study of Arsenic Removal by Novel Hybrid Copper Impregnated Tufa Adsorbents in a Batch System
(Wiley, 2016)
Performance of a novel adsorbent, copper impregnated natural mineral tufa (T-Cu), applicable for efficient arsenic removal is presented in this study. Testing of adsorbent properties encompassed material characterization ...
