Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

Advanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

Single‐Atom Cobalt Species on Curved Hollow Carbon Sphere: Breaking Linear Scaling Relationship Limitations in Electrocatalytic Deactivation of Dilute Antibiotic Pollutants

Advanced Science, EarlyView.
A cobalt (Co)‐SACs consisting of single‐atom Co anchored on a nitrogen‐doped hollow porous carbon sphere (Co1/N‐HCS) is fabricated for electrocatalytic hydrodechlorination of dilute antibiotics. The hollow porous architecture of N‐HCS concentrates the antibiotics, while its curved surface promotes proton transfer at the Co1 site via localized electric ...

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

Advanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...

The Chemical Evolution of the Milky Way

, 1999
The field of chemical evolution modeling of the Galaxy is experiencing in the last years a phase of high activity and important achievements. There are, however, several open questions which still need to be answered. In this review I summarize what have

Toward Complete CO2 Electroconversion: Status, Challenges, and Perspectives

Advanced Energy Materials, EarlyView.
Electrocatalytic CO2 reduction and CO2 batteries face challenges in achieving complete CO2 conversion with high conversion rates and Faradaic efficiency simultaneously. Existing systems compromise one for the other with incomplete CO2 conversion and inefficiencies, hindering practical applications. This perspective highlights state‐of‐the‐art progress,
