(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 ...
Influence of epoxy addition on the thermal, mechanical, and dielectrical properties of polycyanurate films
(John Wiley and Sons Inc., 2018)
In the study, polycyanurate (PCN)/epoxy resin (ER) blends are prepared to enhance the physical properties of cyanate ester resins. The effects of curing schedule and blend composition on their thermal, mechanical, and ...
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 ...
