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 ...
Interactions of Molecules with cis and trans Double Bonds: A Theoretical Study of cis- and trans-2-Butene
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
Noncovalent interactions of cis- and trans-2-butene, as the smallest model systems of molecules with cis and trans double bonds, were studied to find potential differences in interactions of these molecules. The study was ...
Sustained release of alpha-lipoic acid from chitosan microbeads synthetized by inverse emulsion method
(Elsevier Science Bv, Amsterdam, 2016)
The aim of this study was to investigate the encapsulation of a-lipoic acid (LA) onto chitosan microbeads in order to achieve a sustained release. Microbeads of different compositions were synthetized by inverse emulsion ...
The ability of using the cavitation phenomenon as a tool to modify the surface characteristics in micro- and in nano-level
(Elsevier Sci Ltd, Oxford, 2016)
The aim of this paper is to investigate the possible application of the cavitation phenomenon as efficient method to modify the surface properties (e.g. the surface roughness) in the nano- and micro-levels. Aluminum alloy ...
Supercritical carbon dioxide extraction of Trigonella foenum-graecum L. seeds: Process optimization using response surface methodology
(Elsevier Science Bv, Amsterdam, 2016)
Pretreatment of fenugreek (Trigonella foenum-graecum L, Fabaceae) seeds was achieved using the step of defatting and acid hydrolysis. The obtained hydro-isolate (HI) was used as initial feed for diosgenin isolation by ...
Biological potential of puffballs: A comparative analysis
(Elsevier, Amsterdam, 2016)
Handkea utriformis (HU), H. excipuliformis (HE) and Vascellum pratense (VP) mature fruiting bodies methanol extracts were tested for biological activities and active compounds. The extracts showed prominent radical scavenging, ...
Improved beta-amylase production on molasses and sugar beet pulp by a novel strain Paenibacillus chitinolyticus CKS1
(Elsevier, Amsterdam, 2016)
Molasses and sugar beet pulp, by-products in sugar industry, are produced in large amounts annually which create disposal problems. High sugar content in sugar beet molasses enables its use for fermentations while sugar ...
Chitosan-based microparticles for immobilization of TiO2 nanoparticles and their application for photodegradation of textile dyes
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
The present paper deals with removal and photocatalytic degradation of the textile dyes by TiO2 nanoparticles immobilized onto chitosan-based microparticles. The microparticles composed of chitosan (Ch) and poly(methacrylic ...
Cerium-manganese oxide as catalyst for transesterification of soybean oil with subcritical methanol
(Elsevier Science Bv, Amsterdam, 2016)
A heterogeneous cerium-manganese oxide catalyst was synthesized by a co-precipitation method, characterized and tested in soybean oil transesterification with methanol under subcritical condition for methanol. Conversion ...
Prediction of bed expansion of polydisperse quartz sand mixtures fluidized with water
(Elsevier Science Bv, Amsterdam, 2016)
In this paper, the minimum fluidization velocity and bed expansion of polydisperse sand mixtures fluidized with water were investigated. The fluidization experiments were carried out using 19 different fractions of quartz ...
