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 ...
Application of an integrated supercritical extraction and impregnation process for incorporation of thyme extracts into different carriers
(Handbook on Supercritical Fluids: Fundamentals, Properties and Applications, 2014)
Supercritical carbon dioxide (sc2) is known as a good solvent for a wide range of bioactive compounds from natural sources. Extraction of bioactive compounds from plant material using sc2 is a favorable technique for ...
Recent development of bioaugmentation methods for tobacco wastewater treatment
(University of Babes-Bolyai, Cluj-Napoca, 2015)
In production of cigarettes a lot of tobacco waste, with nicotine, goes into the environment. Hence, there is a need for an economic and efficient method to diminish the discharge of hazardous materials from tobacco ...
Efficacy of pastes containing CPP-ACP and CPP-ACFP in patients with Sjogren's syndrome
(Springer Heidelberg, Heidelberg, 2015)
The purpose of this study was to evaluate efficacy of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and casein phosphopeptide-amorphous calcium fluoride phosphate (CPP-ACFP) containing pastes among individuals ...
Hemp Fibers: Old Fibers - New Applications
(Textiles: History, Properties and Performance and Applications, 2014)
Hemp (Cannabis sativa) was most likely the first plant cultivated by mankind for its textile use. Currently, the interest in hemp is focused on its use as a raw material for the production of environmentally friendly ...
Antimicrobial activity of metal oxide nanoparticles supported onto natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The antimicrobial activity of Cu2O, ZnO and NiO nanoparticles supported onto natural clinoptilolite was investigated in the secondary effluent under dark conditions. After 24 h of contact the Cu2O and ZnO nanoparticles ...
Preparation and Characterisation of Novel Biodegradable Material Based on Chitosan and Poly(Itaconic Acid) as Adsorbent for Removal of Reactive Orange 16 Dye from Wastewater
(Springer Int Publishing Ag, Cham, 2015)
Environmental protection has been a topic of great interest in recent years. Discharging azo dyes in aquatic systems contaminates water and causes serious ecological problems. Azo dyes are bio-accumulative, and, due to ...
A kinetic study of the release of vanillin encapsulated in Carnauba wax microcapsules
(Elsevier Sci Ltd, Oxford, 2012)
Thermal release of vanillin encapsulated in Carnauba wax microcapsules was studied by isothermal thermogravimetric analysis at 443, 453, 473, and 483 K. The thermal analysis data were analyzed kinetically and it was found ...
Effects of additives on nickel (ii)-chloride hydrogen reduction for production of nanocomposite catalysts
(Editura Stiintifica Fmr, Bucharest, 2012)
Catalysts based on nickel, as active component, exhibit suitable properties in various heterogeneous catalysis processes; however, they quickly deactivate due to deposits formation during exploitation and sintering at ...
Tryptophan-functionalized gold nanoparticles for deep UV imaging of microbial cells
(Elsevier Science Bv, Amsterdam, 2015)
Biocompatible fluorescent nanostructures were prepared by a functionalization of gold nanoparticles with the amino acid tryptophan. The gold-tryptophan bioconjugates were investigated by TEM and HRTEM and various spectroscopy ...
