Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Analyzing Pentaerythritol Stearate Homologs with NMR Spectroscopy
A pentaerythritol stearate sample with unknown composition was analyzed by nuclear magnetic resonance (NMR) spectroscopy (i.e., 1H NMR, quantitative 13C NMR, DEPT135, 1H-1H COSY, 1H-1H NOESY, 1H-13C HSQC and 1H-13C HMBC).

An effective strategy is developed to overcome the medium temperatures wear resistance degradation in refractory multi‐principal element alloys. By utilizing chemical short‐range ordering to trigger oxygen‐induced amorphization, a composite oxide structure is formed, which combines high hardness with robust stiffness.

Vacuum tribological behaviour of self lubricant quasicrystalline composite coatings
High temperature resistant self-lubricant coatings are needed in space vehicles for components that operate at high temperatures and/or under vacuum. Thick composite lubricant coatings containing quasicrystalline alloys (QC) as the hard phase for wear ...

Tribological Performance Comparison of Lubricating Greases for Electric Vehicle Bearings
EV motors and machine elements operate at higher speeds, generate significant heat and noise (vibration), and subject lubricants (bearings) to multiple degrading factors, requiring thermal stability, wear protection, mitigating wear mechanisms like ...
