Experimental study of insulating properties and behaviour of thermal barrier coating systems in thermo cyclic conditions
(Elsevier Sci Ltd, Oxford, 2015)
The aim of this study was to improve the resistance of turbo jet engine parts exposed to high temperatures and overheating and sudden changes in temperature. For this purpose, three thermal barrier coating (TBC) systems ...
Catalyzed Ester Synthesis Using Candida rugosa Lipase Entrapped by Poly(N-isopropylacrylamide-co-itaconic Acid) Hydrogel
(Hindawi Publishing Corp, New York, 2014)
This study reports the synthesis of polymeric matrices based on N-isopropylacrylamide and itaconic acid and its application for immobilization of lipase from Candida rugosa. The lipase was immobilized by entrapment method. ...
The potential application of TiO2/hydrogel nanocomposite for removal of various textile azo dyes
(Elsevier, Amsterdam, 2014)
TiO2/hydrogel nanocomposite has been utilized for investigation of photocatalytic degradation of three different groups of anionic azo dyes in aqueous solutions under solar light simulating source in order to evaluate its ...
Tailored Adhesion Properties of Acrylate Adhesives on Al Alloys by the Addition of Mn-Al-LDH
(Polymers, 2021)
The goal of this study was to investigate the effect of the structure of Mn-Al layered double hydroxide (LDH) on the adhesion behavior of composite adhesives on two Al alloys (L3005 and L8079). The composite adhesives were ...
Kinetic models of swelling and thermal stability of silver/poly(vinyl Check far alcohol)/chitosan/graphene hydrogels
(Elsevier Science Inc, New York, 2019)
Silver nanoparticles (AgNPs) were synthesized by in situ electrochemical reduction of Ag+ ions in poly (vinyl alcohol)/chitosan/graphene (PVA/CHI/Gr) hydrogel matrices with different concentrations of chitosan. The ...
Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
Numerical determination and experimental validation of the fracture toughness of welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Most of the serious weldment failures lead to catastrophic consequences in terms of damage of other equipment, loss of production, and risks to workers' health and safety. Hence, there is motivation to find margin between ...
Environmentally benign few-bilayer intumescent nanocoating for flame retardant enzyme/plasma modified polyester fabric
(Elsevier Ltd, 2023)
The flammability of polyester textiles remains a significant challenge that must be overcome to allow their use in a variety of clothing and upholstery applications. In this work, water-based polyelectrolyte solutions ...
Influence of TEMPO-Mediated Oxidation on Properties of Hemp Fibers
(Amer Chemical Soc, Washington, 2012)
Hemp fibers are a very interesting natural material for textile and technical applications, but some of these applications require improved and/or specific fiber properties. In order to modify hemp fibers for obtaining ...
Highly Active Rutile TiO2 Nanocrystalline Photocatalysts
(Amer Chemical Soc, Washington, 2020)
The controllable synthesis of rutile TiO2 single crystal particles with the preferential orientation of {111} facets still remains a scientific and technological challenge. Here, we developed a facile route for fabrication ...
