Bilirubin oxidase from myrothecium verrucaria physically absorbed on graphite electrodes. Insights into the alternative resting from and the sources of activity loss [PDF]
, 2015 The oxygen reduction reaction is one of the most important chemical processes in energy converting systems and living organisms. Mediator-less, direct electro-catalytic reduction of oxygen to water was achieved on spectrographite electrodes modified by

Adaptation of the Rist Operating Diagram as a Graphical Tool for the Direct Reduction Shaft
Metals, 2021 The blast-furnace operating diagram proposed by Rist was revised to direct reduction and was specifically applied to the Midrex NGTM process. The use of this graphical tool in the study of an industrial process highlighted the staggered nature of the ...

Mineralogy and solid-state reduction features of typical ironsands from Indonesia
工程科学学报, 2021 With over 100 billion tons of reserves, the ironsands resource is mainly distributed along the “Belt and Road” countries, such as Indonesia. It is the second largest marine resource inferior to petroleum and natural gas.

Towards Drinfeld-Sokolov reduction for quantum groups
, 2000 In this paper we study the Poisson-Lie version of the Drinfeld-Sokolov reduction defined in q-alg/9704011, q-alg/9702016. Using the bialgebra structure related to the new Drinfeld realization of affine quantum groups we describe reduction in terms of ...

Recent advances in electron transfer between biofilms and metals [PDF]
, 2007 Microbial biofilms produce electrochemical interactions with metal surfaces by following a wide variety of different electron exchange pathways. Reviewing the mechanisms identified in the biocorrosion of steels leads us to distinguish direct and indirect

Simulation of Mechanical Degradation of Iron Ore Pellets in a Direct Reduction Furnace
KONA Powder and Particle Journal, 2017 The increase in production of steel in electric arc furnaces in recent years influenced directly the world production of direct reduction iron (DRI). Amongst the most widely used technologies for DRI production is the MIDREX® process. The behavior of the
