DOI: 10.1007/s42243-018-0015-5

Abstract: A kinetic model was developed using FactSage Macro Processing to simulate the reoxidation of Al–Ti-containing steels by CaO–Al2O3–SiO2–MgO slags. The calculated results show a good agreement with the experimental data. Thus, the developed kinetic model… read more here.

DOI: 10.1021/acs.est.1c08927

Abstract: Redox-active quinone and nonquinone moieties represent the electron exchange capacity (EEC) of natural organic matter (NOM), playing an important role in the electron transfer link of microbes and transformation of contaminants/metal minerals. However, the corresponding… read more here.

DOI: 10.1093/femsyr/foac007

Abstract: Abstract While thermotolerance is an attractive trait for yeasts used in industrial ethanol production, oxygen requirements of known thermotolerant species are incompatible with process requirements. Analysis of oxygen-sufficient and oxygen-limited chemostat cultures of the facultatively… read more here.
