Light absorption properties and potential sources of particulate brown carbon in the Pearl River Delta region of China [PDF]

Atmospheric Chemistry and Physics, 2019
Brown carbon (BrC) is a special type of organic aerosol (OA), capable of absorbing solar radiation from near-ultraviolet (UV) to visible wavelengths, which may lead to an increased aerosol radiative effect in the atmosphere.

Energy Dissipation in Nonlinearly Elastic Auxetic and Non‐Auxetic Mechanical Metamaterials with Friction and Material Damping

Advanced Engineering Materials, EarlyView.
This study presents a hyperelastic mechanical metamaterial for elastic energy dissipation. Energy is dissipated within its unit cells by friction assisted by material damping. Frictional contact is enhanced when using auxetic unit cells. The load–displacement plot for one compression cycle shows a pronounced hysteresis loop, indicating that a large ...

Soft Beats: A Dielectric Elastomer‐Based Ventricular Assist Device for Next‐Gen Heart Failure Management

Advanced Engineering Materials, EarlyView.
The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,
