When subjected to electro-mechanical loading, ferroelectrics see their polarization evolve through the nucleation and evolution of domains. Existing mesoscale phase-field models for are typically based on a gradient-descent law order parameter. While this implicitly assumes that domain walls with linear kinetics, experiments instead indicate wall kinetics is nonlinear. This, in turn, an importa...

Long-term electrokinetic processes affect the motion of different soil fractions mainly ionic-species in soil-type environments. Primarily, this governs direct (DC) and alternating (AC) electrical fields due to thermal, acid-base ion gradients generated close electrodes resulted electro-migration, electrophoresis, other electrolysis-related-processes. The migration metal ionic-species, includin...

Mutations in the VMD2 gene cause Best's disease, an inherited form of macular degeneration. The reduction in the light-peak amplitude in the patient's electro-oculogram suggests that bestrophin-1 influences the membrane conductance of the retinal pigment epithelium (RPE). Systemic application of the L-type Ca2+ channel blocker nimodipine reduced the light-peak amplitude in the rat electroretino...

Ammonia electro-oxidation (AEO) is a zero carbon-emitting sustainable means for the generation of hydrogen fuel, but its commercialization deterred due to sluggish reaction kinetics and poisoning expensive metal electrocatalysts. With this perspective, CuO impregnated ?-Al2O3 (CuO/?-Al2O3) hybrid materials were synthesized as effective affordable electrocatalysts investigated AEO in alkaline me...

Abstract Carbon dots (CDs), as a unique zero-dimensional member of carbon materials, have attracted numerous attentions for their potential applications in optoelectronic, biological, and energy related fields. Recently, CDs catalysts conversion reactions under multi-physical conditions such light and/or electricity grown into research frontier due to advantages high visible utilization, fast m...

Ammonia (NH3) is a clean energy source that can either be directly used as fuel or hydrogen carrier due to its high density and content. The NH3 electro-oxidation reaction (AOR) the main in both direct cells electrolysis. AOR thermodynamically favorable; however, sluggish kinetics of result issues such overpotential, slow rate, deactivation, etc. To overcome this, multiple strategies have been ...

Transition metal-based ABO4-type materials have now been paid significant attention due to their excellent electrochemical activity. However, a detailed study understand the active species and its electro-evolution pathway is not traditionally performed. Herein, FeAsO4, bimetallic oxide, has prepared solvothermally. In-depth microscopic spectroscopic studies showed that as-synthesized cocoon-li...

Abstract The mechanism and kinetics of the electro-catalytic oxidation hydrazine by graphene oxide platelets randomly decorated with palladium nanoparticles are deduced using single particle impact electrochemical measurements in buffered aqueous solutions across pH range 2–11. Both hydrazine, N 2 H 4 , protonated 5 + shown to be electroactive following Butler-Volmer kinetics, which relative co...

Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...
