Several Methods of Reducing Discharge Energy for Intrinsic Safety Power Supply
Meikuang Anquan, 2020 In order to reduce the discharge spark energy of the intrinsic safety power supply, several measures are proposed in this paper. When the over-current protection occurs, DC-DC or AC-DC module should be turned off as quickly as possible, and the ...

FEBS Open Bio, EarlyView.We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...
