The closed-loop recycling strategy of Li and Co metal ions based on aqueous Zn-air desalination battery.

Nowadays, it is a global problem to recycle LiCoO from waste lithium-ion batteries (LIBs) due to the deficiency of high business cost and environmental pollution. Here, a novel three-channel ion recovery device based on a Zn-air desalination battery (ZADB) is proposed which can supply energy while separating Li and Co from the recovered solution. The three-channel ZADB device consists of a Zn foil anode chamber with ZnSO anolyte stream, an intermediate chamber with Li and Co recovered stream and an air cathode chamber with LiOH and Co(OH) catholyte stream, chambers are separated by anion exchange membrane (AEM) and cation exchange membrane (CEM) respectively.

Label-free quantification proteomics reveals potential proteins associated with the freshness status of crayfish (Procambarus clarkii) as affected by cooking.

In order to characterize the freshness status of raw material of cooked crayfish products, protein and physicochemical changes were investigated in raw and cooked crayfish from fresh-live state to the early postmortem using Label-free quantification proteomics, total volatile basic nitrogen (TVB-N) and biogenic amines (BAs) analysis. Results showed that the TVB-N and BAs contents in both raw and cooked crayfish remained low levels and no obvious changes were observed within 24 h of postmortem storage at 4 °C. Altogether, six differentially expressed proteins (DEPs) were detected in both C6/C0 and C24/C0 groups by proteomics.
