The electronic/electrochemical properties and activity of ternary Co-Ni-Fe oxyhydroxide oxygen evolution electrocatalysts are shown to be tunable based on composition. The addition of Co to Ni oxyhydroxide shifts the onset of electrical conductivity to more-negative potentials while the addition of Fe dramatically enhances activity. Calculations further show strong electronic hybridization between all the metal cations and oxygen at the valence band edge.

Metal nanoparticles, supported on amorphous SiO2, form nanopores in the SiO2 when heated above 1,000¡æ. In this paper, we show that this behavior is general to a variety of metals (Au, Ag, Cu, Pd, and Pt) and demonstrate a way to control the extent of entrenchment. Further, we propose a mechanism and explain that this entrenchment occurs due to the glass-transition exhibited by amorphous SiO2.

Well-defined PtPb nanocrystals (NCs) have been selectively synthesized via an effective method, and the optimized PtPb octahedra nanocrystals (ONCs)/C is the most active catalyst for the ethanol reforming to H2. X-ray photoelectron spectroscopy (XPS) reveals that the high Pt(0)/Pt(II) ratio in PtPb NCs/C enhances the alcohols reforming. The density functional theory (DFT) studies show the PtPb ONCs possess the highest surface averaged electronic occupation for unit Pt-atom, matching well with XPS results.

The stability of Li@atomic layer deposition (ALD)-carbon nanotube sponge (CNTS) electrodes relies on both the high-surface-area conductive framework and the robust ALD-Al2O3 surface protection layer, which decreases the effective areal current density and stabilizes the electrode/electrolyte interface for Li nuclei,respectively.

Near-infrared (NIR)-controlled cell adhesion: We constructed an NIR-responsive nano-biointerface by introducing a thermal responsive polymer onto a silicon nanowire array with photothermal property. The prepared nano-biointerface showed NIR-controlled reversible cell adhesion and release without the assistance of photosensitive moieties.

Without using noble metals as co-catalysts, multi-node CdS hetero-nanowires (NWs) were grown with defect-rich O-incorporated MoS2 ultrathin nanosheets (NSs). The hetero-NWs exhibited abundant catalytic active sites, substantially improved electric conductivity, and significantly enhanced separation of charge carriers, resulting in superior visible-light photocatalytic properties compared with Pt/CdS NWs, pure CdS NWs, and MoS2 NSs, as well as their physical mixtures.
