Lithium-ion batteries have been widely used in recent decades.

Lithium-ion batteries are the state-of-the-art power source for most consumer electronic devices. Current collectors indispensable components bridging lithium-ion and external circuits, greatly influencing capacity, rate capability long-term stability of batteries. Conventional current collectors, Al Cu foils have been used since first commercial battery, over past two decades, thickness these ...

Thermally and electrochemically driven 18O tracer exchange experiments in H2/H218O atmosphere were performed on SrTi0.7Fe0.3O3 - δ and Ce0.8Gd0.2O2 - δ thin films on single crystalline YSZ substrates. Noble metal current collectors were deposited on both films and electrochemically polarized during the exchange experiment. The resulting tracer distribution was analyzed by spatially resolved sec...

Three-dimensional (3D) structures such as nanowires, nanotubes, and nanorods have the potential to increase surface area, reduce light reflection, and shorten charge carrier transport distances. The assembly of such structures thus holds great promise for enhancing photoelectrochemical solar cell efficiency. In this study, genetically modified Tobacco mosaic virus (TMV1cys) was used to form sel...

Current collectors are essential features of batteries and many other electronic devices being responsible for efficient charge transport to active electrode materials. Three-dimensional (3D), high surface area current collectors considerably improve the performance of cathodes and anodes in batteries, but their technological implementation is impeded by the complexity of their preparation, whi...

garbage collectors are occupationally exposed to a variety of airborne contaminants. the main objective of this study was to evaluate the respiratory health of garbage collectors. this study was carried out in fars province, south of iran. a group of 105 garbage collectors and 93 referent subjects were investigated. a standard questionnaire was administered to both groups. furthermore, subjects...

Lithium Sulfur (Li/S) chemistries are amongst the most promising next-generation battery technologies due to their high theoretical energy density. However, the detrimental effects of their intermediate byproducts, polysulfides (PS), have to be resolved to realize these theoretical performance limits. Confined approaches on using porous carbons to entrap PS have yielded limited success. In this...
