According to the 2D activity map, higher OER activity, described by the limiting energies (GRPD-limiting energies; Supplementary Equation 13), was found on confined MOF structures rather than bulk ones. More importantly, a superior activity can be found for OER on NiFe-BTC//G with the active ...
Using an improved hydrolysis method of inorganic salts assisted with water-bath incubation, ultrasmall water-soluble metal-iron oxide nanoparticles (including Fe3O4, ZnFe2O4and NiFe2O4nanoparticles) were synthesized in aqueous solutions, which were used as T1-weighted contrast agents for magnetic resona...
Anodic oxygen evolution reaction (OER) is recognized as kinetic bottleneck in water electrolysis. Transition metal sites with high valence states can accelerate the reaction kinetics to offer highly intrinsic activity, but suffer from thermodynamic formation barrier. Here, we show subtle engineering of h...
This particular surface oxide has been used for self-stabilization of LM, maintaining metastable shape. The surface tension of oxided Ga-based LM was determined using the puddle height method, and the resulted surface tension was 350–365 mN·m−1 [35]. In addition, water can be used as...
1). Therefore one cannot conclude whether or not an oxide scale uniformly covers the steel surface only the simultaneous presence of the 2 oxides NaCrO2 and NaMnO2 is implied by the data. In our conditions, we obtained good wettability by sodium of the 304L steel, this being testified by ...

In summary, a nonflammable solvent-free LPE was developed for high-performance and safe Li metal batteries. Due to a room-temperature liquid-state brush-like polymer consisting of a polyphosphazene backbone and oligomeric ethylene oxide side chains, the LPE simultaneously addressed the most pressing ...

The efficiency with which renewable fuels and feedstocks are synthesized from electrical sources is limited at present by the sluggish oxygen evolution reaction (OER) in pH-neutral media. We took the view that generating transition-metal sites with high
