Doping‐Modulated Strain Enhancing the Phosphate Tolerance on PtFe Alloys for High‐Temperature Proton Exchange Membrane Fuel Cells

Advanced Functional Materials, 2021
In high‐temperature proton exchange membrane fuel cells (HT‐PEMFCs), the poisoning of Pt by phosphoric species severely affects the kinetics of the oxygen reduction reaction, which restricts their commercialized application.

High-Resolution Flood Risk Assessment in Small Streams Using DSM–DEM Integration and Airborne LiDAR Data

Sustainability
Flood risk in small streams is rising under climate change, as small catchments are highly vulnerable to short, intense storms. We develop a high-resolution assessment that integrates a Digital Surface Model (DSM), a Digital Elevation Model (DEM), and ...

Negative impact of low IGF-1 levels and hypovitaminosis D on coronary artery disease severity and prognosis in patients with AMI

European Heart Journal: Acute Cardiovascular Care
Low IGF-1 levels, low-grade inflammation and Vitamin D (VitD) are implicated in the pathogenesis of coronary heart disease (CHD). While hypovitaminosis D (HypoD) and low-grade inflammation are associated with presence of CHD and its severity, there
