Architecting nano‐Al/HMX/CuO energetic micro‐units unlocks superior interface and highly efficient combustion

open access: yesInfoMat, EarlyView.
Improving the dispersion of nano‐aluminum is of great importance in explosives and propellants. The spherical Al/HMX/CuO energetic micro‐units were prepared using microchannel technology, which significantly improved the uniformity and dispersion of nano‐Al. It also enhanced the mass and heat transfer efficiency between the fuel and oxidizer components,

On Lubrication States after a Running-In Process in Aqueous Lubrication

Langmuir, 2019
Recently, many studies have reported the ultralow friction coefficient of sliding friction between rigid solid surfaces in aqueous lubrication. A running-in process that goes through high-friction and friction-decreasing regions to a stable ultralow friction region is often required. However, the role of the friction-decreasing region is often ascribed
