Particle characterization of polydisperse quartz filtration sand
(Elsevier Science Bv, Amsterdam, 2014)
In this paper, different methods for particle characterization were applied to 16 polydisperse fractions of quartz filtration sand obtained by sieving, with sieve diameters in the interval d(m) = 0359 to 2.415. For each ...
Novel membrane adsorbers incorporating functionalized polyglycidyl methacrylate
(Elsevier Science Bv, Amsterdam, 2014)
Asymmetric polyethersulfone membranes with submicron particles comprising crosslinked glycidyl methacrylate copolymer were prepared by a combination of a traditional immersion precipitation process for making membranes ...
Corrosion of stainless steel 316Ti tank for the transport 12-15% of hypochlorite solution
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The corrosion of the transport tank materials made of stainless steel 316Ti is investigated in a solution containing 12-15% of the commercial sodium hypochlorite solution. Using the electrochemical techniques, weight loss ...
The specificity of alpha-glucosidase from Saccharomyces cerevisiae differs depending on the type of reaction: hydrolysis versus transglucosylation
(Springer, New York, 2014)
Our investigation of the catalytic properties of Saccharomyces cerevisiae alpha-glucosidase (AGL) using hydroxybenzyl alcohol (HBA) isomers as transglucosylation substrates and their glucosides in hydrolytic reactions ...
Microwave-assisted extraction for the recovery of antioxidants from waste Equisetum arvense
(Elsevier, Amsterdam, 2014)
Microwave-assisted extraction was optimised by the response surface methodology in order to enhance the extraction of polyphenols from Equisetum arvense (horsetail). Under the optimal conditions the total polyphenol content ...
A structure-property relationship study of bent-core mesogens with pyridine as the central unit
(Royal Soc Chemistry, Cambridge, 2014)
Three series of bent-core mesogens having pyridine as the central unit have been synthesized and characterized. A series of 2,6-diaminopyridine derivatives capable of forming inter- and intramolecular hydrogen bonds exhibit ...
Polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics fabricated by Spark Plasma Sintering: Densification and microstructure development
(Elsevier Sci Ltd, Oxford, 2014)
Using Spark Plasma Sintering it is possible to produce polycrystalline ceramics of very fine microstructure and good mechanical properties. This work presents the fabrication of such ceramics using Eu3+-doped (Y0.7Gd0.3)(2)O-3 ...
Morpho-structural, adsorption and electrochemical characteristics of serpentinite
(Elsevier Science Bv, Amsterdam, 2016)
Pollution control and water purification are the main concerns associated with hazardous component eliminations from wastewaters which have inspired the research, among the others, on various clay minerals as useful ...
Pretreatment of Natural Materials Used for Supercritical Fluid Extraction of Commercial Phytopharmaceuticals
(Wiley-VCH Verlag Gmbh, Weinheim, 2014)
A proper method was to be developed for the pretreatment of different types of natural materials in order to increase the efficiency of supercritical fluid extraction (SFE) regarding yield and active substance content. The ...
Improvement of the epoxy coating properties by incorporation of polyaniline surface treated TiO2 nanoparticles previously modified with vitamin B6
(Elsevier Science Sa, Lausanne, 2016)
Novel TiO2-PANI core-shell nanocomposite, prepared by in situ oxidative polymerization of aniline in the presence of TiO2 nanoparticles surface modified with vitamin B6, was used to reinforce epoxy resin. The size of ...
