Synergetic pyrolysis of lithium-ion battery cathodes with polyethylene terephthalate for efficient metal recovery and battery regeneration.

Spent LiNiCoMnO (x + y + z = 1) and polyethylene terephthalate are major solid wastes due to the growing Li-ion battery market and widespread plastic usage. Here we propose a synergistic pyrolysis strategy to recover valuable metals by thermally treating LiNiCoMnO and polyethylene terephthalate. With polyethylene terephthalate assistance, LiNiCoMnO decomposes at 400 °C, and fully converts to LiCO, MnO, and Ni-Co alloy at 550 °C within 30 min, using a 1.

Biochemical properties of Bacillus Calmette Guerin ribonuclease III.

Double-stranded RNA (dsRNA) is discovered to participate in the regulation of gene expression in both bacterial and eukaryotic cells. Members of ribonuclease III (RNase III) family recognize RNA motifs and cleave substrates at specific sites in a divalent-metal-ion-dependent manner. In this study, we find the RNase III from Bacillus Calmette Guerin (BCG-RNase III) cleaves small hairpin RNA based on the conserved stem structure associated with Mycobacterium 16S ribosomal RNA precursor at specific sites which are not determined.
