Achieving Highly Reversible Mn/MnO Conversion Reaction in Electrolytic Zn-MnO Batteries via Electrochemical-Chemical Process Regulation.

Despite the widespread interest in electrolytic Zn-MnO batteries with excellent output voltage and high theoretical capacity, the spontaneous disproportionation reaction of free Mn along with the disorderly deposited inactive MnO results in the low Mn/MnO conversion reversibility, which seriously affects their cycling stability. Here, we propose a novel aqueous SiO colloidal electrolyte with FeSO mediator (denoted as SF electrolyte) based on a bidirectional electrochemical-chemical model to achieve dual regulation of the MnO deposition/dissolution process. During the charging process, the SiO colloidal particles located at the carbon felt interface and the electrolyte bulk phase simultaneously provide sufficient disproportionation sites for the diffused Mn to guide the orderly rapid deposition of MnO.

[Cloning and identification of the variable region gene of mouse anti-human BAFF mAb].

Aim: To obtain the variable region gene sequence of heavy and light chain of mouse anti-human BAFF monoclonal antibody (mAb) on base of BAFF mAb which was cloned in our laboratory.

Methods: The total RNA was extracted from mouse anti-human BAFF mAb hybridoma cell line FMMUB(4);, and then the RNA was reverse transcribed into cDNA. Specific primers were designed to amplify the targeted gene.
