Published: June 18, 2021

Iron (Fe) is the fourth most abundant element in earth's crust and plays important roles both biological chemical processes. The redox reactivity of various Fe(II) forms has gained increasing attention over recent decades areas (bio) geochemistry, environmental chemistry engineering, material sciences. goal this paper to review these advances current state knowledge environment. Specifically, comprehensive focuses on four types species including aqueous Fe(II), complexed with ligands, minerals bearing structural sorbed mineral oxide surfaces. formation pathways, factors governing reactivity, insights into potential mechanisms, comparison, characterization techniques are discussed reference breakthroughs field where possible. We also cover applications zerovalent iron, microbial processes, biogeochemical cycling carbon nutrients, their abiotic oxidation related processes natural engineered systems.

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.

Contaminant containment for sustainable remediation of persistent contaminants in soil and groundwater

Journal of Hazardous Materials, Journal Year: 2023, Volume and Issue: 455, P. 131575 - 131575

Published: May 6, 2023

Contaminant containment measures are often necessary to prevent or minimize offsite movement of contaminated materials for disposal other purposes when they can be buried left in place due extensive subsurface contamination. These include physical, chemical, and biological technologies such as impermeable permeable barriers, stabilization solidification, phytostabilization. is advantageous because it stop contaminant plumes from migrating further allow pollutant reduction at sites where the source inaccessible cannot removed. Moreover, unlike options, do not require excavation substrates. However, regular inspections monitor mobilization migration. This review critically evaluates sources persistent contaminants, different approaches remediation, various physical-chemical-biological processes containment. Additionally, provides case studies operations under real simulated field conditions. In summary, essential preventing contamination reducing risks public health environment. While periodic monitoring necessary, benefits make a valuable remediation option methods feasible.

Tide-Triggered Production of Reactive Oxygen Species in Coastal Soils

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 56(16), P. 11888 - 11896

Published: July 11, 2022

We report an unrecognized, tidal source of reactive oxygen species (ROS). Using a newly developed ROS-trapping gel film, we observed hot spots for ROS generation within ∼2.5 mm coastal surface soil. Kinetic analyses showed rapid production hydroxyl radicals (•OH), superoxide (O2•–), and hydrogen peroxide (H2O2) upon shift from high tide to low tide. The exhibited distinct rhythmic fluctuation. oscillations the redox potential dissolved concentration followed same pattern as •OH production, suggesting alternating oxic–anoxic conditions main geochemical drive production. Nationwide field investigations confirmed widespread sustainable via processes (22.1–117.4 μmol/m2/day), which was 5- 36-fold more efficient than those classical photochemical routes (1.5–7.6 μmol/m2/day). Analyses soil physicochemical properties demonstrated that redox-metastable components such redox-active iron minerals organic matter played key role in storing electrons at shuttling infiltrated Our work sheds light on ubiquitous but previously overlooked ROS, may accelerate carbon metal cycles well pollutant degradation soils.

Iron (Fe) oxides are widely recognized to prevent the degradation of organic matter (OM) in environments, thereby promoting persistence carbon (OC) soils. Thus, discerning association mechanisms Fe and OC interactions is key effectively influencing dynamics extent C cycling Previous studies have focused on i) quantifying oxide-bound (Fe-OC) individual ii) investigating distribution adsorption capacity Fe-OC, iii) assessing redox transformation Fe-OC. Furthermore, widespread application high-tech instrumentation methods has greatly contributed a better understanding mechanism mineral assemblages past few decades. However, literature reviews comprehensively summarized Fe-OC distributions, associations, characteristics soil-plant systems. Here, contents among different environments reviewed. In addition, processes related OM occurring at mineral-organic interfaces also described. Recent highlighted that diverse occur between OC, with compounds adhering due their huge specific surfaces area active reaction sites. Moreover, we review for micro-interfaces. Lastly, developmental prospects coupled geochemical soil molecular- nano-scales outlined. The summary suggests combined advanced techniques should be used future research explore micro-interfaces situ descriptions assemblages.

Published: Oct. 18, 2024

Immunotherapy has made significant strides in cancer treatment, particularly through immune checkpoint blockade (ICB), which shown notable clinical benefits across various tumor types. Despite the transformative impact of ICB treatment therapy, only a minority patients exhibit positive response to it. In with solid tumors, those who respond well typically demonstrate an active profile referred as "hot" (immune-inflamed) phenotype. On other hand, non-responsive may distinct "cold" (immune-desert) phenotype, differing from features tumors. Additionally, there is more nuanced "excluded" positioned between and categories, known type. Effective differentiation understanding intrinsic factors, characteristics, TME, external factors are critical for predicting results. It widely accepted that therapy exerts profound effect on limited efficacy against or "altered" necessitating combinations therapeutic modalities enhance cell infiltration into tissue convert tumors ones. Therefore, aligning traits this review systematically delineates respective influencing extensively discusses varied approaches drug targets based assess efficacy.
