Metal Degassing in Vacuum-Chamber of Circulating Vacuum Degasser of JSC EVRAZ NTMK

Steel in Translation, 2022
For smelting of high-quality metal for transport purposes, it is necessary to limit the content of harmful impurities in it, including dissolved gases. For example, hydrogen content in the finished product should not exceed more than 2 ppm. In order to obtain low residual hydrogen content in steel in the converter shop of JSC EVRAZ NTMK, the transport ...

Competing effects of hydrogen, carbon, and sulfur degassing on the redox evolution of rising melts on terrestrial (exo)planets

Astronomy & Astrophysics
Context. Volcanic degassing is a key process controlling the formation and chemical evolution of secondary atmospheres on terrestrial planets. The redox state of ascending magma, commonly expressed as oxygen fugacity (fO2), strongly influences the ...

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

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 ...
