Molecular Dynamics Investigation on Grain Size-Dependent Superelastic Behavior of CuZr Shape Memory Alloys

Metals
The superelasticity of CuZr shape memory alloys (SMAs) originates from stress-induced transformations between the B2 (austenite) and B19’ (martensite) phases. Grain size is a key parameter affecting the superelasticity of shape memory alloys.

Surface effects on the superelasticity of nanohelices

Journal of Physics: Condensed Matter, 2012
Helical nanomaterials with superelasticity have a wide range of promising applications in micro-/nanoelectromechanical systems. Based on the theory of surface elasticity, we present a nonlinear rod model to investigate the superelasticity of nanohelices. Our results demonstrate that the superelasticity of nanohelices exhibits a distinct size dependence

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.
