Self‐Expanding Cardiovascular Stents: Potentials and Challenges of Shape Memory Biomaterials

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 6, June 2026.
ABSTRACT Cardiovascular diseases affect a large portion of the global population and remain leading causes of morbidity and mortality. Endovascular stenting, a minimally invasive procedure, enables the insertion and deployment of stents to restore arterial patency without open surgery.

Development Of A Pavement Rutting Model Using Shakedown Theory

International Journal on Pavement Engineering & Asphalt Technology, 2015
Abstract The rutting of flexible pavements during their exploitation is considered to be one of the main problems in UK as well as worldwide. It is a serious mode of distress alongside fatigue in bituminous pavements that may lead to premature failure, as indicated by permanent deformation or rut depth along the wheel load path, and results in early ...

Subsurface Single‐Atom Catalyst Enabled by Mechanochemical Synthesis for Oxidation Chemistry

Angewandte Chemie, Volume 136, Issue 42, October 14, 2024.
The mechanochemical approach has been shown to be an effective method of regulating the position of single atoms. Controlling single atoms at the surface or subsurface results in catalysts with very different adsorption properties, leading to different reaction mechanisms.
