An experimental study on the compressive response of CFRP honeycombs with various cell configurations
(Elsevier Ltd, 2019)
The experimental investigation on the compressive response of carbon fiber reinforced polymer (CFRP) honeycombs with various cell configurations was carried out in the present work. The CFRP honeycomb specimens were ...
The effect of potassium modification on structural properties and catalytic activity of copper and iron containing SBA-16 catalysts for selective oxidation of ethanol
(Elsevier Ltd, 2019)
Copper and iron SBA-16 catalysts were synthesized using hydrothermal method and modified with potassium. XRD patterns showed that characteristic peaks of SBA-16 for all catalysts did not destroy with metal loading. The ...
Analysis of analytical capacity for Fisher-Snedecor F fading channels with different transmission schemes
(Institution of Engineering and Technology, 2019)
This Letter presents capacity analysis of Fisher-Snedecor F fading channels under different transmission strategies. To this end, novel analytical expressions are proposed for optimal rate adaptation with constant transmit ...
Microcontroller-based test system for determining the P-N type and Seebeck coefficient of the thermoelectric semiconductors
(Elsevier B.V., 2019)
In this study, a microcontroller-based test system is designed and realized to determine the Seebeck coefficient (alpha) and electrical conductivity type of thermoelectric (TE) semiconductors. The test system uses Hot-Probe ...
Thermal and mechanical characterization of composite produced from recycled PE and flue gas desulfurization gypsum
(SAGE Publications Ltd, 2019)
Varying ratios of industrial byproduct of flue gas desulfurization gypsum and recycled polyethylene were used to prepare composite matrices in order to develop an eco-friendly material. Small ratios of maleic anhydride ...
Polymer-graphene hybrid stabilized ruthenium nanocatalysts for the dimethylamine-borane dehydrogenation at ambient conditions
(Elsevier B.V., 2019)
In this work, we reported a new catalyst consistent of graphene oxide (GO) – poly(N-vinyl-2-pyrrolidone) (PVP) hybrid supported ruthenium nanoparticles and called as Ru@GO-PVP. The GO-coupled PVP nanosheets were prepared ...
Functionalized 2-(hydroxyethyl) methacrylate (HEMA)-co-acrylamide (AAm) hydrogels: Kinetic and Isotherm Modelling Analysis on the Removal of Cu(II) Ions
(Prints Publications Pvt Ltd, 2019)
A functionalized hydrogel composed of 2-(hydroxyethyl) methacrylate (HEMA) and acrylamide (AAm) was synthesized by amination and saponification reactions, respectively, and its functionality was examined for the elimination ...
Blend membranes of sulfonated poly (ether ether ketone) and thermoplastic poly (urethane) for fuel cells
(Springer, 2019)
Membranes used in polymer electrolyte membrane fuel cells (PEMFCs) have critical importance because their properties directly affect the performance of fuel cell. For this purpose, blend membranes based on sulfonated poly ...
Smart glass electrochromic device fabrication of uniform tungsten oxide films from its powder synthesized by solution combustion method
(Elsevier, 2019)
Recently, there has been renewed interest in tungsten oxide based electrochromic (EC) materials. A variety of studies related to these materials have been reported, however, no serious studies so far have been reported on ...
