The electrostatic attraction between electrons and nuclei is a fundamental force in electrochemistry. This drives the interaction nuclei, providing potential for redox reactions. As result, it basis of chemistry. In recent years, organic electrochemistry has made significant progress oxidative hydrogen evolution coupling sacrificial anode electroreduction, thanks to its efficient environmentall...

A red phosphorus-graphene nanosheet hybrid is reported as an anode material for lithium-ion batteries. Graphene nanosheets form a sea-like, highly electronically conductive matrix, where the island-like phosphorus particles are dispersed. Benefiting from this structure and properties of phosphorus, the hybrid delivers high initial capacity and exhibits promising retention at 60 °C.

MnCO3 particles uniformly distributed on large-area graphene form 2D composites whose large-area character enables them to self-assemble face-to-face into orderly packed electrodes. Such regular structures form continuous and efficient transport networks, leading to outstanding lithium storage with high capacity, ultralong cycle life, and excellent rate capability--all characteristics that are ...

A practical method to determine the heating and cooling curves of x-ray tube assemblies with rotating anode x-ray tube is proposed. Available procedures to obtain these curves as described in the literature are performed during operation of the equipment, and the precision of the method depends on the knowledge of the total energy applied in the system. In the present work we describe procedure...

Tin dioxide nanotubes coated with ultrathin N-doped carbon film (N-doped SnO2/C NTs) are prepared through a sacrificial template method for the first time. It was employed as anodes lithium-ion batteries (LIBs) and delivered high reversible capacity of 909.5 mAh g?1 at 0.5 A after 200 cycles, outstanding stability 551.7 500 cycles 1 g?1, excellent rate performance 1069.2 280 cycles. Such superi...

in this study, the performance of electro-coagulation in combination with aluminum sacrificial anode, in removal of zinc and copper has been investigated. several parameters, such as pollutant concentration, ph, electrical potential, cod, turbidity and contact time were studied to achieve a higher removal capacity. variable concentrations (5-50-500 ppm) of zinc and copper solutions were prepare...

by appearance of human societies, the spiritual needs of different individuals and societies to worship the creator and to donate in order to attain the health and to fulfill the wishes had caused them to erect the specific places for offering the sacrificial materials. this article is generally a brief study on the places to donate and offer the sacrificial materials to sacred places regarding...

Two modes of electrochemical harvesting for microalgae were investigated in the current work. A sacrificial anode (aluminum) was used to study electrocoagulation-flotation process, and a nonsacrificial (graphite) investigate electroflotation process. The inspected effect chloride ions concentration interelectrode distance on performance processes. results demonstrated that both electrodes achie...

Abstract Using the wire beam electrode technique, electrochemical impedance spectroscopy, energy-dispersive X-ray formation of calcareous deposits in a tidal zone and its effects on corrosion protection Q235 steel under cathodic were studied. Results showed that production aragonite CaCO 3 crystals significantly reduced from immersion to high-tide zone, protective performance deposited layer we...
