“…The prepared membranes exhibited maximum OH À conductivities of 47.5 mS cm À1 at 90 C and 30 mS cm À1 at 60 C. Methanol permeability was found to be in the order of 10 À8 cm 2 s À1 , which was considerably lower than that of Nafion ® membrane. Most recently, Nikoli c et al [135] fabricated a polyvinyl alcohol (PVA) matrix using a solution-cast method and a g-irradiation crosslinking technique. In their work, PVA was first completely dissolved in boiling water bubbled with Ar, then this solution was exposed to g-rays ( 60 Co) for irradiation at room temperature.…”

Alkaline water electrolysis is one of the easiest methods for hydrogen production that has the advantage of simplicity. The major challenges in the water electrolysis are the reduce energy consumption, cost and maintenance and to increase reliability, durability and safety. In this regard, the electrolytic production of hydrogen is systematically studied by commercially available graphite electrode at room temperature. The experimental results showed the rate of production of hydrogen gas was significantly affected when the reaction parameters such as effect of electrolyte concentration, temperature, applied voltage and reaction time are varied. From the experimental results, it has been found that graphite is a good choice for the production of maximum hydrogen compared to various other electrodes.

“…The wt loss (%) of S-3 is sig-nificantly higher, which is due to the addition of (5 wt.%) silica NFs. Actually, the wt loss (%) is due to the breaking of physically weak and chemically strong bonds and, hence, partially evaporated, results in the formation of PVDFbased NC FSs holding NFs [38]. The main dramatic wt.…”

The silica zinc oxide nanoparticles filled poly-vinylidene-fluoride (PVDF)-based nanocomposite flexible sheets (NC FSs) are synthesized by co-precipitation method. The X-ray diffraction patterns reveal the development of various diffraction planes related to zinc oxide (ZnO) and SiO2 phases. The crystallinity of ZnO phase is decreased with increasing weight percent (wt.%) of silica nanofillers (NFs). The scanning electron microscope microstructure of synthesized PVDF-based NCs FSs is changed with increasing wt.% of silica NFs. The energy-dispersive X-ray spectroscopy and Fourier-transform infrared spectroscopy analyses confirm the presence of different elements and the formation of chemical bonding between them. In high temperature region, the weight-loss of synthesized PVDF-based NCs FSs is decreased from 89.90% to 49.26% with increasing wt.% of silica NFs. The values of dielectric permittivity, loss-factor, impedance, and AC-conductivity of PVDF-based NC FSs synthesized for maximum amount of silica NFs are found to be 13.7, 0.03, 0.16 MΩ, and 19.9 × 10 − 6 S/m, respectively. Results show that the synthesized PVDF-based NC FSs are the potential candidates of light emitting diodes and energy storage devices.
