Metal oxidation is one of the spontaneous chemical reaction, which is hard to control. Most metals inevitably have at least a few layers of oxides on the surface in natural environment. Because of the large impact of metal oxidation on infrastructure and transportation, surface oxidation and its role on structure and property have attracted significant attentions on the fundamental aspects of o...

In situ techniques with high temporal, spatial and chemical resolution are key to understand ubiquitous solid-state phase transformations, which are crucial to many technological applications. Hard X-ray spectro-imaging can visualize electrochemically driven phase transformations but demands considerably large samples with strong absorption signal so far. Here we show a conceptually new data an...

In order to further improve the energy and power density of state-of-the-art lithium-ion batteries (LIBs), new cell chemistries and, therefore, new active materials with alternative storage mechanisms are needed. Herein, we report on the structural and electrochemical characterization of Fe-doped ZnO samples with varying dopant concentrations, potentially serving as anode for LIBs (Rechargeable...

An inductively coupled plasma torch (ICPT) system was used to synthesize nanosilica particles starting both from glass powders from fluorescent lamps and tetraethyl orthosilicate (TEOS) as precursors. The effect of the curtain gas on nanoparticles size, morphology and composition was studied by the use of BET, SEM and EDS analysis.

background: b cell cll/lymphoma 2 protein, bcl-2, is an important anti-apoptotic factor that has been implicated in lithium’s neuroprotective effect. however, most studies have focused on assessing the effects of lithium in neurons, ignoring examination of bcl-2 in astrocytes, which also influence neuronal survival and are affected in bipolar disorder. the aim of this study was to evaluate whet...

The oxide glass-based anodes for lithium-ion Batteries (LiBs) still suffer from two critical drawbacks, that is, low reversible capacity and electrical conductivity. Here, we report a new way to overcome the drawbacks. Specifically, chose 50Fe2O3–50P2O5 (50Fe50P) glass as anode material LiBs, then thermally treat it at 1118 K (Tg+345 K) 0.5 h under reducing atmosphere (5 mol% H2+95 Ar). thermal...
