A light-weight coaxial h-boron nitride (BN)/carbon nanotube (CNT) wire which can tolerate 1,200 ⊥ in air has been fabricated. Thermionic electron emission (1,200 K) and thermally activated conductivity (1,000 K) are two principal mechanisms of the insulation failure of h-BN at high temperature. This light-weight high temperature wire can transmit electrical signal normally under burning by liquefied petroleum gas flame. It is hoped the h-BN/CNT wire will open up new possibilities for a wide spectrum of applications in extreme high temperature conditions.

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.

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.
