Study on the pyrolysis products of two different hardwood lignins in the presence of NiO contained-zeolites
(Elsevier Ltd, 2017)
Several NiO contained-zeolites (NiO/H-ZSM-5, NiO/H-BETA and NiO/H-Y) prepared by a mechanochemical dry milling (MCDM) were tested in the pyrolysis of two hardwood lignins: Eucalyptus (EUC) and a mixture of birch and aspen ...
Effect of nutrient supplements on growth and viability of Lactobacillus johnsonii NRRL B-2178 in whey
(Elsevier Sci Ltd, Oxford, 2014)
The main objectives of the paper were to study the effects of nutrient supplementation of cows' whey on the growth and viability of the probiotic microorganism Lactobacillus johnsonii NRRL B-2178. Because of the short ...
Adsorption of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from water onto modified multi-walled carbon nanotubes, carbon cryogel, and carbonized hydrothermal carbon
(Environmental Science and Pollution Research, 2022)
Carbon materials of different structural and textural properties (multi-walled carbon nanotubes, carbon cryogel, and carbonized hydrothermal carbon) were used as adsorbents for the removal of estrone, 17 beta-estradiol, ...
Image analysis and the finite element method in the characterization of the influence of porosity parameters on the mechanical properties of porous EVA/PMMA polymer blends
(Elsevier B.V., 2019)
Poly(ethylene-co-vinyl acetate) (EVA) and poly(methyl methacrylate) (PMMA) are two incompatible polymers. Compatibilization of EVA/PMMA polymer blends with EVA-g-PMMA decreased the pore diameter and improved the mechanical ...
Epoxy-silanization - tool for improvement of silica nanoparticles as support for lipase immobilization with respect to esterification activity
(Wiley, Hoboken, 2016)
BACKGROUND: In this study, in order to obtain the best support for the immobilization of lipase from Candida rugosa (CRL), the procedure for chemical modification of fumed silica nanoparticles (FNS) with (3-Glycidyloxypropyl) ...
Silver/Poly(N-vinyl-2-pyrrolidone) Hydrogel Nanocomposites Obtained by Electrochemical Synthesis of Silver Nanoparticles Inside the Polymer Hydrogel Aimed for Biomedical Applications
(Wiley, Hoboken, 2014)
Silver nanoparticles were produced inside a poly(N-vinyl-2-pyrrolidone) hydrogel (PVP) by an innovative method based on the electrochemical reduction of Ag+ ions within the swollen PVP hydrogel. UV-visible spectroscopy ...
Effect of gentisic acid on the structural-functional properties of liposomes incorporating beta-sitosterol
(Elsevier, Amsterdam, 2019)
Multifunctional liposomes incorporating beta-sitosterol were developed for delivery of gentisic acid (GA). The interactions of both compounds with phospholipid bilayer were interpreted viaeffects of different beta-sitosterol ...
Hydrothermal synthesis of TiO2/carbon composites and their application for removal of organic pollutants
(Elsevier, Amsterdam, 2019)
TiO2/carbon composites were synthesized by hydrothermal carbonization, using titanium isopropoxide and glucose precursor solution to obtain composites with Ti/C molar ratios ranging from 0.05 to 0.30. Characterization of ...
On the photophysical properties of a liquid crystal dimer based on 4-nitrostilbene: A combined experimental and theoretical study
(Journal of Molecular Liquids, 2021)
A new liquid crystal dimer, 1,12-bis(4-(2-(4-nitrophenyl)ethenyl)phenoxy)dodecane, was synthesized and structurally characterized. The compound exhibited enantiotropic nematic phase. The spectroscopic properties were ...
