A New Family of Ternary Intermetallic Compounds with Dualistic Atomic Ordering – The ZIP Phases
The ZIP phases are ternary intermetallic compounds with dualistic atomic ordering, i.e., they exhibit one face‐centered cubic (fcc; space group Fd3¯$\bar 3$m) variant and one hexagonal (space group P63/mmc) variant. The ZIP phases in the Nb‐Si‐Ni system are the Nb3SiNi2 (fcc) and Ni3SiNb2 (hexagonal) ternary IMCs, crystal structure schematics of which ...

The Promise of Solid Lubricants for a Sustainable Future
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Quantum‐confined lepidocrocite titanate nanofilaments are doped, bottom‐up, with Mn+2, Fe+2, Co+2, Ni+2, and Cu+2 to tune electronic structure and catalysis. Doping narrows the bandgap—by up to ∼0.8 eV—and extends visible absorption. Ni‐doped filaments accelerate oxygen evolution (319 mV at 10 mA cm−2) and TM‐doped samples rapidly degrade rhodamine 6G (
