Microstructure and tribological properties of Ti/TiN/DLC coating for piston pin hole

To enhance the wear resistance of piston pin-hole surfaces and prolong piston service life, titanium (Ti)/titanium nitride (TiN)/diamond-like carbon (DLC) composite coatings were prepared on aluminium alloy substrates by multi-arc ion plating. The effects of the dinitrogen (N2):a...

Polarization Properties Orientation Coupling Regulates Molecular Packing and Device Performance Beyond Dipole Moment Strength in Organic Solar Cells

ABSTRACT Strong interactions between large dipole moment additives and host materials have been widely used to modulate molecular packing in organic solar cells (OSCs), while most studies focuses on dipole moment magnitude instead of the polarization properties orientation. Here,...

Fe 3+ ‐Triggered Scalable Slow‐Corrosion Engineering for Industrial Anion Exchange Membrane Water Electrolysis at 2.0 A cm −2

ABSTRACT The practical application of anion exchange membrane water electrolysis (AEMWE) is hindered by the lack of durable anodes for industrial‐scale current densities (≥ 1000 mA cm −2 ). Herein, we report a scalable Fe 3+ ‐triggered homogeneous slow‐corrosion strategy to fabri...

Monopulse electrodeposited nanoflower-like Co-Mo-P/Cu catalyst for efficient hydrogen production from hydrolysis of sodium borohydride: Synergistic mechanism and electrochemical reactivation

High-performance catalysts for hydrogen generation from sodium borohydride (NaBH 4 ) hydrolysis are pivotal for portable energy applications. In this work, a hierarchical Co-Mo-P/Cu catalyst with spherical nanoflower structure was synthesized via a facile one-step monopulse flow...
