Microstructure modulation of hard carbon derived from long-flame coal to improve electrochemical sodium storage performances

open access: yesFuel Processing Technology
Widely sourced precursors for hard carbon with high performances are still a major challenge for industrializing sodium-ion batteries. Herein, long-flame coal was adopted as the precursors to prepare hard carbon by carbonization at different temperatures,

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

open access: yesFEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Evoking surface‐driven capacitive process through sulfur implantation into nitrogen‐coordinated hard carbon hollow spheres achieves superior alkali metal ion storage beyond lithium

open access: yesBattery Energy, 2023
Owing to the specific merits of low cost, abundant sources, and high physicochemical stability, carbonaceous materials are promising anode candidates for K+/Na+ storage, whereas their limited specific capacity and unfavorable rate capability remain ...

Heterotropic regulation and negative homotropic cooperativity

open access: yesFEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Sulfur‐doped hard carbon hybrid anodes with dual lithium‐ion/metal storage bifunctionality for high‐energy‐density lithium‐ion batteries

open access: yesCarbon Energy, 2023
Bifunctional hybrid anodes (BHAs), which are both a high‐performance active host material for lithium‐ion storage as well as a guiding agent for homogeneous lithium metal nucleation and growth, exhibit significant potential as anodes for next‐generation ...

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...
