Neighborhood effects on health: A multilevel analysis of neighborhood environment, physical activity and public health in suburban Shanghai

With great concern over the health-promoting environment worldwide, there is a growing body of research into the neighborhood effects on health beyond the sole focus on individual socioeconomic disadvantages and lifestyle risks. Our study contributes to neighborhood health research by investigating the combined effects of multi-dimensional...

Degradation behaviors and in-vivo biocompatibility of a rare earth- and aluminum-free magnesium-based stent

Biodegradable stents can provide scaffolding and anti-restenosis benefits in the short term and then gradually disappear over time to free the vessel, among which the Mg-based biodegradable metal stents have been prosperously developed. In the present study, a Mg-8.5Li (wt.%) alloy (RE- and Al-free) with high ductility (> 40%) was...

In Situ Fabrication and Reactivation of Highly Selective and Stable Ag Catalysts for Electrochemical CO₂ Conversion

In this work, the highly selective and stable electrocatalytic reduction of CO₂ to CO on nanostructured Ag electrocatalysts is presented. The Ag electrocatalysts are synthesized by the electroreduction of Ag₂CO₃ formed by in situ anodic-etching of Ag foil in a KHCO₃ electrolyte. After 3 min of this...
