Constructing Serrated Boride Composite Layer for Enhancing Wear Resistance of Ti6Al4V Alloy
Rare Metals, EarlyView.ABSTRACT Appropriate configuration combined with strong interface bonding is the essential requirement for developing high wear‐resistant coatings. Herein, based on the powder‐pack boriding process, the properties of Ti6Al4V alloy are effectively improved by constructing a serrate tribological boride composite layer.

Phase space Feynman path integrals [PDF]
Journal of Mathematical Physics, 2002 A rigorous mathematical formulation of the “phase space Feynman path integral” is given in a general setting. This is then applied to yield a representation of solutions of the Schrödinger equation with potential depending both on the position and momentum variables.

Orbitally Driven Anomalous Thermal Transport Under High Pressure in Gallium Nitride
Rare Metals, EarlyView.ABSTRACT Extreme conditions such as high pressure offer opportunities for innovative materials design and applications. For over a century, studies on thermal transport in crystals under high hydrostatic pressure have shown that lattice thermal conductivity generally exhibits a monotonic increase with pressure.

A High Capacity‐Long Cycling Concurrent Strategy of Ti3C2/MgH2 for Lithium Storage
Rare Metals, EarlyView.ABSTRACT The excellent electrical conductivity and superior cycling stability render Ti3C2 MXene a promising Li ion battery anode. Nevertheless, the practical implementation of Ti3C2 MXene in commercial applications faces significant challenges, predominantly due to the low specific capacity.
