Ablation‐Immune Thermal Armor Via Microstructural‐Compatibility Design for Extreme Thermal Conditions

Advanced Science, EarlyView.
This study unveils a microstructural‐compatibility design strategy that integrates reactive melt infiltration with plasma spraying to fabricate carbon fiber‐reinforced ZrC‐SiC composites. The deliberate incorporation of SiC into the ZrC coating releases heat accumulation, suppresses detrimental lamellar ZrO2 formation, and reduces residual stress. This

Evaluation of range of motion restriction within the hip joint [PDF]

, 2012
In Total Hip Arthroplasty, determining the impingement free range of motion requirement is a complex task. This is because in the native hip, motion is restricted by both impingement as well as soft tissue restraint. The aim of this study is to determine

A Scalable Double‐Sided Wet Etching Strategy for Large‐Area Mushroom‐Shaped Bionic Adhesives

Advanced Science, EarlyView.
This work presents a scalable manufacturing strategy for high‐performance, large‐area, mushroom‐shaped bio‐inspired adhesives. Using a double‐sided wet etching process, the complex 3D metal molds are fabricated rapidly and controllably. The resulting adhesive structures exhibit strong, stable adhesion under various conditions, including atmosphere and ...
