Advanced Science, EarlyView.A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.

Advanced Science, EarlyView.The SIRT5/ACAA2 axis maintains lipid metabolic homeostasis in RTECs by promoting ACAA2 desuccinylation and preserving its stability and enzymatic activity, thereby sustaining FAO and limiting PUFA and PUFA‐containing phospholipid accumulation. Under CaOx stress, SIRT5 downregulation impairs FAO, promotes oxidative stress and ferroptosis, and enhances ...

Synthesis of molecular photoconverting systems based on tetraphenylporphyrin and purpurin 18
Тонкие химические технологии, 2010 Donor-acceptor systems based on 5-(p-aminophenyl)-10,15,20-triphenylporphyrin, purpurin 18 and 2-(2-hydroxyethyl)thio-3-methyl-1,4-naphthoquinone were synthesized to simulate the natural photoconverting systems. Their spectral properties were studied.

The In Situ Electrochemical−Chemical Cascade Strategy for Pyruvic Acid Synthesis
Advanced Science, EarlyView.By employing an “unsaturation−oxygen coordination engineering” strategy, the local coordination environment is regulated to achieve efficient electrochemical synthesis of H2O2. Importantly, an electrochemical−chemical coupled cascade strategy is utilized for the efficient preparation of pyruvic acid via lactic acid oxidation. ABSTRACT Hydrogen peroxide

Advanced Science, EarlyView.Conjugated polymer‐supported bioelectrochemical systems are shown to enhance microbial electrosynthesis by triggering coordinated electrochemical, transcriptional, post‐transcriptional (sRNA), metabolic, and protein‐level responses. Integrated multi‐omics and electrochemical analyses reveal selective physiological remodeling associated with improved ...
