Cryogenic Infrared Spectroscopy Unmasks Gas‐Phase Charge Migration in Mucin‐Type O‐Glycans

open access: yesSmall, EarlyView.
Protons in a sugar rush: O‐glycans are vital biomolecules, challenging to analyze due to isomeric forms. Using ion mobility spectrometry, cryogenic IR spectroscopy, and ab initio calculations, isomeric O‐glycan cores can be distinguished. At cryogenic temperatures, multiple deprotomers were identified, which interconvert at ambient conditions via rapid

Bifunctional Electrocatalysts in Rechargeable Lithium‐Gas Batteries: Material Evolution and Mechanistic Insights from Metal‐Free Carbons to Carbon‐Supported Single‐Atom Sites

open access: yesSmall, EarlyView.
This review charts the material evolution of bifunctional electrocatalysts for rechargeable lithium‐gas batteries. It highlights the journey from heteroatom‐doped, metal‐free carbon architectures to precision‐engineered carbon‐supported single‐atom sites. The discussion focuses on mechanistic insights into how these catalysts govern reversible O2, CO2,

Recent Advances in Bimetallic Site Catalysts for Photocatalytic Ammonia Synthesis: Synergistic Effects and Design Strategies

open access: yesSmall, EarlyView.
Photocatalytic ammonia synthesis employs photocatalysts to harness solar energy, driving the reduction of N2 into NH3. The synergistic effects of bimetallic active sites are used to overcome limitations of single‐metal systems and optimize electronic structures.

Local Eviction Moratoria and the Spread of COVID‐19

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT At different stages during the initial onset of the COVID‐19 pandemic, various US states and local municipalities enacted eviction moratoria. One of the main aims of these moratoria was to slow the spread of COVID‐19 infections. We deploy a semiparametric difference‐in‐differences approach with an event study specification to examine whether ...

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.
