FINEAU (2021–2024) is a trans-disciplinary research project involving French, Serbian, Italian, Portuguese and Romanian colleagues, a French agricultural cooperative and two surface-treatment industries, intending to propose ...
Immobilized Alcalase on Micron- and Submicron-Sized Alginate Beads as a Potential Biocatalyst for Hydrolysis of Food Proteins
(Catalysts, 2021)
Enzymatic hydrolysis of food proteins is convenient method to improve their functional properties and physiological activity. Herein, the successful covalent attachment of alcalase on alginate micron and submicron beads ...
The effect of natural modifiers for starch hydrophobization on performance of composite based on ethylene acrylic acid copolymer
(Wiley, Hoboken, 2021)
As a renewable resource, starch is considered to be fully biodegradable and nonpolluting to the environment but the hygroscopicity of starch is the main disadvantage for wider applicability in the production of a polymer-based ...
Composition-property relationship of polyurethane networks based on polycaprolactone diol
(Springer, New York, 2021)
This work was focused on the synthesis of polyurethane networks (PUNs) based on polycaprolactone (PCL) as soft segment (SS) and Boltorn (R) aliphatic hyperbranched polyester of the second pseudo generation and 4,4 ...
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 ...
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 ...
Improvement in cavitation resistance of poly (vinyl butyral) composite films with silica nanoparticles: A technical note
(Polymers & Polymer Composites, 2021)
In this study poly (vinyl butyral)/silica (PVB/SiO2) composite films were subjected to the cavitation process. The experiments were carried out with a 10 wt.% PVB solution in ethanol. Silica nanoparticles were added into ...
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 ...
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 ...
