DOI: 10.1021/acs.est.3c00033
Abstract: Reduced iron-containing clay (RIC) minerals have been documented to exhibit antibacterial activity through a synergistic action of extracellular membrane attack and intracellular oxidation of cellular components. However, the relative importance between extracellular and intracellular processes… read more here.

DOI: 10.1128/aem.01662-24
Abstract: ABSTRACT Reduced iron was abundant in Earth’s surface environments before their oxygenation, so iron oxidation could have been a common metabolism on the early Earth. Consequently, modern microbial iron oxidation is sometimes seen as a… read more here.

DOI: 10.3390/ma15165691
Abstract: Since the European Union defined ambitious CO2 emission targets, low-carbon-emission alternatives to the widespread integrated blast furnace (BF)—basic oxygen furnace (BOF) steelmaking strategy—are demanded. Direct reduction (DR) with natural gas as the reducing agent, already… read more here.
