Glycogen is conventionally considered as a transient energy reserve that can be rapidly synthesized for glucose accumulation and mobilized for ATP production. However, this conception is not completely applicable to prokaryotes due to glycogen structural heterogeneity. A number of studies noticed that glycogen with small average chain length g in bacteria has the potential to degrade slowly, which might prolong bacterial environment survival. This phenomenon was previously examined and later formulated as the durable energy storage mechanism hypothesis. Although recent research has been warming to the hypothesis, experimental validation is still missing at current stage. In this review, we summarized recent progress of the hypothesis, provided a supporting mathematical model, and explored the technical pitfalls that shall be avoided in glycogen study.

The rational design and synthesis of bifunctionally active and durable oxygen electrocatalysts have garnered significant attention for electrochemical energy conversion and storage. Intermetallic nanostructures are particularly promising for these applications due to their unique catalytic properties and exceptional durability. In this study, we present a fascinating synthetic approach for the direct synthesis of a bifunctional oxygen electrocatalyst based on nitrogen-doped carbon-encapsulated ordered PdFe (o-PdFe@NC) intermetallic, using a cyano-bridged bimetallic single-source precursor tailored for aqueous rechargeable zinc-air batteries (ZABs).

Metal nanoclusters (NCs), comprising tens to hundreds of metal atoms, are condensed matter with concrete molecular structures and discrete energy levels. Compared to metal atoms and nanoparticles, metal NCs exhibit unique physicochemical properties, especially fascinating electrocatalytic activities. This review focuses on recent progress in the precise synthesis of metal NCs and their applications in electrochemical analysis of various disease biomarkers.

The dual-site electrocatalysts formed by metal single atoms combines with metal nanoparticles represent a promising strategy to enhance both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) performance. Herein, defect engineering is applied to dual-site ORR and OER electrocatalysts. Its design, synthesis, structural properties, and catalytic performance experimentally and theoretically are insightfully studied for the single-atomic Fe─N and the adjacent FeCo nanoalloy (FeCo) as dual-site loading on nitrogen-doped graphene aerogel (Fe─N/FeCo@NGA).

Radiative cooling textiles designed to reflect incoming sunlight and enhance mid-infrared (MIR) emissivity show great potential for ensuring personal thermal comfort. Thus, these textiles are gaining prominence as a means of combating the heat stress induced by global warming. Nonetheless, integrating radiative cooling effects into scalable textile materials for personal thermoregulation remains a formidable challenge.

An essential aspect of improving market openness, fostering investor trust, and allowing the establishment and implementation of sustainable development policies lies in enhancing the disclosure quality of new energy firms. This study examines the influence of corporate governance on the disclosure quality of new energy companies listed on the Chinese A-share market. The analysis is conducted using a two-way fixed-effects model and particularly focuses on the role of green transformation in this relationship.
