Microhardness measurement optimization in green derived silica/polyester composites using response surface methodology
(SAGE Publications Ltd., 2024)
Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modifiedplant provenance biosilica particles were synthesized and characterized. An unsaturated polyester resin ...
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 ...
Numerical simulation of fatigue crack propagation in friction stir welded joint made of Al 2024-T351 alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded T joints has been simulated numerically. Crack propagation in stiffened part of the structure between two ...
Platinum nanocatalysts on metal oxide based supports for low temperature fuel cell applications
(Royal Soc Chemistry, Cambridge, 2016)
In this manuscript a survey of the contemporary research related to platinum nanocatalysts on metal oxide based supports for low temperature fuel cell applications is presented. Different carbon based supports, used as ...
Solvent effects on structural changes in self-healing epoxy composites
(Elsevier Science Sa, Lausanne, 2020)
Nowadays, there is a very high importance of composite research and variety of their applications in the modern world. In that sense, we researched hollow glass capillaries filled with dissolved Grubbs catalyst (GC) and ...
The effect of TiO 2 on the structure and devitrification behavior of potassium titanium germanate glass
(Springer Netherlands, 2006)
The effect of replacing 20 mol% of GeO 2 by TiO 2 on the properties of potassium germanate glass was investigated. The structure and devitrification behaviour of glasses were studied by Fourier transform infrared spectroscopy ...
Synthesis and characterization of high-pressure and high-temperature sphene (CaTiSiO5)
(Springer Verlag, 2014)
Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibro-milling for homogenization and activation of precursors. During the high-pressure and ...
Composition, structure and potential energy application of nitrogen doped carbon cryogels
(Materials Chemistry and Physics, 2020)
Resorcinol–formaldehyde (RF) cryogels were synthesized by sol–gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogel (CC) was obtained by pyrolyzing RF cryogels ...
Hydrogen peroxide oxidation on passive iron in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
The kinetics of hydrogen peroxide oxidation were studied on passive iron in alkaline solutions of pH ranging from 9.8 to 13.8, using the rotating disk electrode. Measurements were taken using the linear sweep technique. ...
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 ...
