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 ...
Liquid metalsare fundamentally unique compared to other molecular andionic liquidsas a reaction solvent and thus allow suitable circumstances for chemical reactions[6–8]. Besides, some liquid metals obtain a self-limiting nativeoxide“skin” on the surface, which, if withdrawn faultlessly, gives a...
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...
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...
the water/metal halide systems are not simple. Water can react with themetal halideto yield a variety of species depending on the concentration ratios and the nature of the metal halide. In particular, the correspondingLewis acidmay form (equation5). The extent to which HX can act as a pro...

2 3 La O , a basic metal oxide, buffers the pH of the reactant solution to pH 8–9 during the 2 3 reaction. The reactant solution was evacuated several times to remove air completely prior to irradiation under a 300 W xenon lamp and a water filter. The wavelength of the incident ...
The remarkable Ru displacement, greater than 25 pm locally (15 pm on average), is on par with that of the B-site cation in a prototypical ferroelectric oxide BaTiO3. The large polarity from Ru off-centring is surprising since Ru ions dominantly contribute electrons at the Fermi level ...
In (c–e), the small droplets on the surface after imbibition are water through the reaction between gallium oxide and HCl vapor. No significant effect of water formation on the wetting was observed. The water could be easily removed by a simple drying process. Full size image Electrical ...
