Solar‐driven co‐evolution of H2 and H2O2 from pure water splitting over emerging photocatalysts: Detailed mechanism and future outlook

open access: yesPhotoMat, EarlyView., 2023
Photocatalytic water splitting for co‐evolution of H2 and H2O2 is deemed as a sustainable and promising strategy to address energy and environment issues, thus receiving increasing attention and realizing continuous achievements. This review aims to offer a deep understanding of the mechanism for H2 and H2O2 co‐evolution and the design principle of ...

Systematically Engineering for Efficient Production of 3‐Methyl‐1‐Butanol in Escherichia coli

open access: yesAdvanced Science, EarlyView.
An integrated metabolic engineering strategy was established for high‐level 3‐methyl‐1‐butanol biosynthesis in Escherichia coli. Molecular dynamics‐guided semi‐rational engineering of dihydroxyacid dehydratase uncovered and relieved key catalytic bottlenecks, while adaptive laboratory evolution enhanced strain robustness.

The Thermonuclear Explosion Of Chandrasekhar Mass White Dwarfs [PDF]

open access: yes, 1996
The flame born in the deep interior of a white dwarf that becomes a Type Ia supernova is subject to several instabilities. We briefly review these instabilities and the corresponding flame acceleration. We discuss the conditions necessary for each of the

Polar Lattice‐Distorted Motifs Enable Synergy of Local Polarization/Dipole Fields for Concurrent Glyphosate Wastewater Remediation and CO Evolution

open access: yesAdvanced Science, EarlyView.
Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.
