Summary: Microbial electrosynthesis is a renewable energy platform that converts carbon dioxide into useful chemicals to reduce carbon footprint. However, challenges such as electrode structures, current densities, and product selectivity remain. A three-dimensional macroporous sponge coated with a carbon nanotube/MXene composite was found to enhance charge transfer efficiency, microbial enrichment, and current density. The coated sponge showed improved mass diffusion, microbial growth, and production of butyrate.

Summary: In microbial electrosynthesis, providing additional electron donors can direct the production towards more diverse and longer chain organic chemicals. Supplying formate and ethanol significantly increased the production of butyrate and butanol, while ethanol was found to provide sufficient energy for butyrate production from acetate in the absence of a polarised cathode. The study suggests that the initial reduction of acetate to ethanol, consumed for the production of C4 products through acetate, could be associated with the production of C4 products in the presence of only a cathodic electrode or a cathodic electrode and formate.

Summary: Developing high-performance biocathodes is a challenging aspect in microbial electrosynthesis (MES) systems and is a major factor limiting its output. In this study, a hollow porous carbon (PC) with MXenes coating was developed to facilitate the direct delivery of CO2 to microorganisms. The result showed that MXene@PC(Ti3C2T x @PC) had a surface area of 434 m(2)/g. The Ti3C2T x @PC MES cycle demonstrated enhanced electron transfer and an increase in butyrate production compared to the uncoated control.

Summary: Electromethanogenesis is a microbial process that reduces carbon dioxide to produce methane using a cathode as an electron donor. The shape of the electrode plays a significant role in the performance of the biocathodes and the overall efficiency of the reactor. This study evaluated the influence of electrode shape by installing carbon-based electrodes with different constructions in an electromethanogenic reactor. The results showed that the electrode geometry affected the performance of the biocathodes, with the carbon brush electrode contributing more to current generation and electrical capacitance compared to the carbon felt electrode.

Summary: Microbial electrosynthesis using a carbon felt electrode modified with reduced graphene-oxide (rgoCF) as a methanogenic biocathode showed improved methane production compared to a control carbon felt electrode (CF). The rgoCF electrode generated almost 30% higher current density and had lower charge transfer and ohmic resistances by 50%. The presence of bacteria and archaea was also increased in the rgoCF electrode. The study estimated that a high-quality biogas (>95% methane concentration) can be produced within a certain CO2 feeding rate range.

Summary: Microbial anodes and oxygen reducing microbial cathodes were designed separately and then combined to form two-compartment microbial fuel cells. The MFCs produced significant power density in a hypersaline medium, with Desulfuromonas sp. identified as key species of the anodes. The efficiency of the cathodes was linked to the development of a redox system centered at a certain voltage and the presence of specific phylogenetically linked bacteria. Comparing different MFCs' performances suggested that maintaining longer polarization at a certain voltage could promote growth of specific bacteria on the cathode and enhance MFC performance.

Summary: A novel Sn/SnOx@Ti3C2Tx adsorbent was fabricated by in situ growth of Sn/SnOx particles on Ti3C2Tx nanosheets using electrostatic attraction and liquid-phase reduction. The Sn/SnOx particles were uniformly anchored onto the Ti3C2Tx surface, forming a sandwich-like-structured nanocomposite. The introduced particles increased the space between the nanosheets, providing more active sites for Sr2+ ion removal. The adsorption capacity of Sn/SnOx@Ti3C2Tx for Sr2+ ions was 71.04 mg/g at 298 K, and it showed promising potential for the removal of Sr2+ ions from aqueous media.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
