Abstract The resolving ability of widefield fluorescence microscopy is fundamentally limited by out-of-focus background owing to its low axial resolution, particularly for densely labeled biological samples. Although total internal reflection fluorescence (TIRF) microscopy provid...

Synergistic Regulation of Homoacetogenesis and Electrochemical Electron Supply Enhances CO2-Assisted Caproate Production from Waste Activated Sludge

Abstract Municipal sewage treatment has become an energy-intensive sector associated with substantial CO2 emissions and waste activated sludge (WAS) generation. Chain elongation (CE), as a promising carbon resource recovery route, enables the conversion of sludge-derived short-ch...

Selective transport of plasma-derived reactive species through the plant aquaporin channels: a molecular dynamics study

Abstract The selective permeability of reactive oxygen and nitrogen species (RONS), generated by cold atmospheric plasma (CAP), through plant aquaporins was investigated to identify plasma-derived species capable of intracellular delivery. Using atomistic molecular dynamics and e...

CEO undergraduate natural disaster experiences and corporate social performance

Our paper investigates the relationship between CEOs’ experiences of natural disasters during their undergraduate studies and the ESG performance of their firms. Using a panel dataset of U.S. listed firms, we find that, on average, companies led by these CEOs achieve superior ESG...

Effect of integrated die-casting on microstructure and mechanical properties of large-scale complex thin-walled RE-Mg alloy components for new energy vehicles

In this work, vacuum-assisted high-pressure die casting (HPDC) was employed to fabricate an integrated RE-Mg alloy rear floor for new energy vehicles (NEVs). The correlations among microstructure evolution, mechanical properties, melt flow, and filling behavior of the integrated...
