A critical review of mineral–microbe interaction and co-evolution: mechanisms and applications

National Science Review, Journal Year: 2022, Volume and Issue: 9(10)

Published: July 4, 2022

Mineral–microbe interactions play important roles in environmental change, biogeochemical cycling of elements and formation ore deposits. Minerals provide both beneficial (physical chemical protection, nutrients, energy) detrimental (toxic substances oxidative pressure) effects to microbes, resulting mineral-specific microbial colonization. Microbes impact dissolution, transformation precipitation minerals through their activity, either genetically controlled or metabolism-induced biomineralization. Through these interactions, microbes co-evolve Earth history. typically occur at microscopic scale but the effect is often manifested global scale. Despite advances achieved decades research, major questions remain. Four areas are identified for future research: integrating mineral ecology, establishing biosignatures, linking laboratory mechanistic investigation field observation, manipulating mineral–microbe benefit humankind.

Interfacial reactions drive all elemental cycling on Earth and play pivotal roles in human activities such as agriculture, water purification, energy production storage, environmental contaminant remediation, nuclear waste repository management. The onset of the 21st century marked beginning a more detailed understanding mineral aqueous interfaces enabled by advances techniques that use tunable high-flux focused ultrafast laser X-ray sources to provide near-atomic measurement resolution, well nanofabrication approaches enable transmission electron microscopy liquid cell. This leap into atomic- nanometer-scale measurements has uncovered scale-dependent phenomena whose reaction thermodynamics, kinetics, pathways deviate from previous observations made larger systems. A second key advance is new experimental evidence for what scientists hypothesized but could not test previously, namely, interfacial chemical are frequently driven "anomalies" or "non-idealities" defects, nanoconfinement, other nontypical structures. Third, progress computational chemistry yielded insights allow move beyond simple schematics, leading molecular model these complex interfaces. In combination with surface-sensitive measurements, we have gained knowledge structure dynamics, including underlying solid surface immediately adjacent ions, enabling better definition constitutes oxide- silicate-water critical review discusses how science progresses ideal solid-water realistic systems, focusing accomplishments last 20 years identifying challenges future opportunities community address. We anticipate next will focus predicting dynamic transient reactive structures over greater spatial temporal ranges systems structural complexity. Closer collaborations theoretical experts across disciplines continue be achieving this great aspiration.

Rapid self-heating synthesis of Fe-based nanomaterial catalyst for advanced oxidation

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Aug. 17, 2023

Abstract Iron-based catalysts are promising candidates for advanced oxidation process-based wastewater remediation. However, the preparation of these materials often involves complex and energy intensive syntheses. Further, due to inherent limitations conditions, it is challenging realise full potential catalyst. Herein, we develop an iron-based nanomaterial catalyst via soft carbon assisted flash joule heating (FJH). FJH rapid temperature increase, electric shock, cooling, process simultaneously transforms a low-grade iron mineral (FeS) into electron rich nano Fe 0 /FeS heterostructure embedded in thin-bedded graphene. The efficient consumes 34 times less than conventional pyrolysis. Density functional theory calculations indicate that delocalization FJH-derived improves its binding ability with peroxydisulfate bidentate binuclear model, thereby enhancing ·OH yield organics mineralization. Fe-based exhibits strong catalytic performance over wide pH range. Similar can be prepared using other commonly available precursors. Finally, also present strategy continuous automated production catalysts.

Reactive oxygen species (ROS) play key roles in driving biogeochemical processes. Recent studies have revealed nonphotochemical electron transfer from redox-active substances (e.g., iron minerals) to as a new route for ROS production. Yet, naturally occurring minerals mainly exist thermodynamically stable forms, restraining their potential Here, we report that tide-induced redox oscillations can activate enhanced •OH production intertidal soils (15.8 ± 0.5 μmol/m2) was found be 5.9-fold more efficient than those supratidal soils. Moreover, incubation of under tidal fluctuations dramatically by 4.3-fold. The hydrology triggered alternation between biotic reduction and abiotic oxidation could accelerate the reactive ferrous ions amorphous ferric oxyhydroxides, making into metastable phases (RAMPs) with reduced crystallinity promoting surface electrochemical activities. Those RAMPs displayed activity Investigations nationwide coastal verified ubiquitously Our study demonstrates effective formation hydrological perturbations, which provides insights natural sources.
