sodium-ion batteriesHard carbons are promising anode candidates for sodium-ion batteries due\nto their excellent Na-storage performance, abundant resources, and low\ncost. Despite the recent advances in hard carbons, the interpretation of the\nNa-storage mechanism in hard carbons remains unclear, ...
Potassium Ion Storage: Direct Structure-Performance Comparison of All-Carbon Potassium and Sodium Ion Capacitors (Adv. Sci. 12/2019) A hard carbon ion insertion anode gives much higher overpotential with K+ vs Na+. This significantly lowers the energy–power of symmetric hybrid potassium... Z Xu...
In addition, it is also necessary to produce cells of some resistance to stresses they are exposed to during downstream processing, storage, and in vivo applications. These include pH, dryness, and osmotic and thermal stresses. Cultivation strategy during scaling up of the process can be designed...
Layered NaxMeO2(Me=transition metal) oxides, the most common electrode materials for sodium-ion batteries, fall into different phases according to their stacking sequences. Although the crystalline phase is well known to largely influence the electrochemical performance of these materials, the structure...
K-containing polyanion compounds hold great potential as anodes for sodium-ion batteries considering their large ion transport channels and stable open frameworks; however, sodium storage behavior has rarely been studied, and the mechanism remains unclea
The upregulation of the cold-induced gene COR47 was attributed to mannitol present in the ANEs, but could just as well have been caused by, for example, a high sodium concentration in these particular ANEs. They concluded that “the ANE composition−biostimulant activity relationship is complex...
NPs are most often formed by a “bottom up” chemical mechanism which requires a metal salt and a strong reducing agent, such as sodium borohydride [17]. The reaction involved reduces the metal cation to a neutral state, which provides a nucleation site for the metal atoms to aggregate and...
Globally, electrochemical energy storage is one of the most important research fields. Numerous electrochemical energy storage devices, including lithium-ion batteries (LIBs), sodium-ion batteries (SIBs), potassium-ion batteries (PIBs), zinc-ion batteries (ZIBs), and supercapacitors, power human life...
Although the exact mechanism of dopaminergic neuronal loss in SNpc is not well understood. Mitochondrial damage, energy failure, oxidative stress, excitotoxicity, protein misfolding and their aggregation, impairment of protein clearance pathways, cell-autonomous mechanisms and “prion-like protein infection...
surface redox reactions and precipitation mechanisms including neoformation of clay mineral layered structures. In IADs, outer-sphere adsorption is the major retention mechanism of REE ions. By contrast, the use of clay minerals in pollution control relies on various mechanisms that can coexist, ...
