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,

Cervical Inlet Patches in R‐CPD: An Unrecognized Predictor of Treatment Failure

open access: yesThe Laryngoscope, EarlyView.
This retrospective cohort study identified cervical inlet patches (CIP) in 19.8% of patients undergoing cricopharyngeal botulinum toxin injection for R‐CPD. CIP presence and increasing age independently predicted failure to sustain a long‐term treatment response, suggesting that CIP may be an underrecognized factor in R‐CPD treatment durability ...
