A detailed UV-Vis spectral investigation of six azo dyes derived from benzoic- and cinnamic acids: experimental and theoretical insight
(Comptes Rendus Chimie, 2021)
Six donor-pi-acceptor azo dyes, with altered donor- (p-hydroxyphenyl-and naphthalene-2ol) and carboxylic based acceptor groups, were subjected to detailed solvatochromic and tautomeric investigation in different environments ...
The effect of incompletely condensed polyhedral oligomeric silsesquioxanes (POSS) on hybrid film adhesion
(Elsevier Sci Ltd, Oxford, 2020)
The objective of this study was to investigate the influence of polyhedral oligomeric silsesquioxane (POSS) structure on the adhesion behaviour of composite films onto a metallic surface. The composite films consisted of ...
Immobilization of horseradish peroxidase onto Purolite (R) A109 and its anthraquinone dye biodegradation and detoxification potential
(Wiley, Hoboken, 2020)
Horseradish peroxidase (HRP) is a highly specific enzyme with great potential for use in the decolorization of synthetic dyes. A comprehensive study of HRP immobilization using various techniques such as adsorption and ...
The effect of polyhedral oligosilsesquioxanes (POSS) on cavitation resistance of hybrid acrylate films
(Wiley, Hoboken, 2020)
Cavitation erosion of hybrid acrylate composite films with polyhedral oligosilsesquioxanes (POSS) was investigated in this study. The hybrid films are made with 1, 3 and 5 wt% of POSS reagents containing: (a) hydroxyl ...
Amino-modified hollow alumina spheres: effective adsorbent for Cd2+, Pb2+, As(V), and diclofenac removal
(Environmental Science and Pollution Research, 2021)
A simple sol-gel method and external gelatinization method of hollow alumina spheres synthesis were developed in this study. The spheres were modified with polyethyleneimine (PEI) producing PEI-Al2O3 via (3-glycidyloxypr ...
Influence of microstructure and roughness level on corrosion resistance of the austenitic stainless steel welded joint
(Materials and Corrosion-Werkstoffe Und Korrosion, 2021)
The influence of microstructure and surface roughness of the X5CrNi18-10 austenitic stainless steel-welded joint on resistance to uniform, pitting, and intergranular corrosion, as well as on the stability of the passive ...
Influence of inhibitors on the corrosion behavior of the X5CrNi18 10 stainless steel-welded joint
(Wiley-VCH Verlag Gmbh, Weinheim, 2021)
This study considers the corrosion behavior of the X5CrNi18 10 stainless steel-welded joint in NaCl solution, with and without the presence of several corrosion inhibitors (NaNO3, Ce(NO3)(3), and CeCl3). The degree of ...
Design of halloysite modification for improvement of mechanical properties of the epoxy based nanocomposites
(Polymer Composites, 2021)
In this study, halloysite nanotubes (HNT) were modified by: 3-glycidyloxypropyltrimethoxysilane (GLYMO), 3-aminopropyltrimethoxysilane (APTES), and 2,2-Bis[4-(glycidyloxy) phenyl] propane (DGEBA), and incorporated in the ...
Enzymatically derived oil-based L-ascorbyl esters: Synthesis, antioxidant properties and controlled release from cosmetic formulations
(Elsevier B.V., 2020)
Lipase-catalyzed transesterification of vitamin C by natural triglycerides is promising approach for cost-efficient synthesis of liposoluble food and cosmetic antioxidants. Nevertheless, application of these alternative ...
Preparation of floating polymer-valsartan delivery systems using supercritical CO2
(Journal of Polymer Research, 2021)
This study investigates pharmaceutical polymers (Soluplus((R)), HPMCAS, and Eudragit((R)) E100) and supercritical CO2-assisted process for preparation of floating valsartan delivery systems. Tested process (at pressure of ...
