N-(substituted phenyl)-2-chloroacetamides: LSER and LFER study
(Elsevier, Amsterdam, 2019)
The UV absorption spectra of twelve N-(substituted phenyl)-2-chloroacetamides were recorded in eighteen solvents. The effect of specific and non-specific solvent-solute interactions on the absorption maxima shifts was ...
Dissolution of copper mineral phases in biological fluids and the controlled release of copper ions from mineralized alginate hydrogels
(IOP Publishing Ltd, Bristol, 2015)
Here we investigate the dissolution behaviour of copper minerals contained within biocompatible alginate hydrogels. Copper has a number of biological effects and has most recently been evaluated as an alternative to expensive ...
Enhanced sorption of Cu2+ from sulfate solutions onto modified electric arc furnace slag
(Elsevier Science Bv, Amsterdam, 2019)
Pristine electric arc furnace slag (EAFS) as well as EAFS modified by alkali activation i.e. alkali activated slag (AAS) have found a novel application as adsorbents used in Cu2+ removal from sulfate solutions. The adsorption ...
Effects of different mechanical treatments on structural changes of lignocellulosic waste biomass and subsequent Cu(II) removal kinetics
(Elsevier, Amsterdam, 2019)
In this paper, the character of structural changes induced by different mechanical treatments to Prunus persica stones (PSs), and its subsequent effect on biosorption kinetics of Cu(II) were investigated. PSs were processed ...
A fluorescent nanoprobe for single bacterium tracking: functionalization of silver nanoparticles with tryptophan to probe the nanoparticle accumulation with single cell resolution
(Royal Soc Chemistry, Cambridge, 2016)
The investigation of the interaction of silver nanoparticles and live bacteria cells is of particular importance for understanding and controlling their bactericidal properties. In this study, the process of internalization ...
beta-Amylase production from packaging-industry wastewater using a novel strain Paenibacillus chitinolyticus CKS 1
(Royal Society of Chemistry, 2015)
Transport packaging factories generate a large amount of wastewater that contains residuals of starch glue. These residuals could be used as substrates for microorganism growth and enzyme production. In this study, ...
Keratin-polyethylene oxide bio-nanocomposites reinforced with ultrasonically functionalized graphene
(Royal Society of Chemistry, 2015)
Polyethylene oxide (PEO) functionalized graphene (f-G) was prepared by ultrasonication of pristine graphene in PEO aqueous solution. The feasible sonication protocol of PEO degradation and graphene functionalization enabled ...
Conformational stability of 5-substituted orotic acid derivatives analyzed by measuring C-13 NMR chemical shifts and applying linear free energy relationships
(Elsevier, Amsterdam, 2019)
Conformational stability of various 5-substituted orotic acid derivatives was studied by applying linear free energy relationships (LFER) to the C-13 NMR chemical shifts. The correlation analysis for the substituent-induced ...
Voltammetric behavior and determination of the macrolide antibiotics azithromycin, clarithromycin and roxithromycin at a renewable silver - amalgam film electrode
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The renewable silver-amalgam film electrode (Hg(Ag)FE) was applied for voltammetric characterization and determination of semi-synthetic macrolide antibiotics azithromycin (AZI), clarithromycin (CLA) and roxithromycin (ROX) ...
High performance unsaturated polyester based nanocomposites: Effect of vinyl modified nanosilica on mechanical properties
(Budapest Univ Technol & Econ, Budapest, 2016)
Influences of the vinyl modified nanosilica Aerosil (R) 380, i.e., vinyl and methacryloyl silane coupling agent and linseed oil fatty acids (BD) reactive residues, on the mechanical properties of the unsaturated polyester ...
