Summary: This study presents a Raman investigation of MoS2 powders and MoS2 individual layers functionalized with organic molecules. It is found that the functionalized MoS2 powders are oxidized into MoO3 upon increasing temperature, while the mechanically exfoliated individual MoS2 layers do not undergo the same transformation. During the covalent functionalization, few-layer MoS2 undergoes a partial transition from the 2H to the 1T' crystallographic phase.

Summary: In this study, MXene nanosheets were functionalized with sodium lignosulfonate (LS) and MoS2 nanosheets were intercalated between the functionalized MXene layers to fabricate a two-dimensional MXene membrane. This composite membrane exhibited high water permeation and excellent dye separation characteristics. It had a significantly higher pure water flux compared to the unfunctionalized MXene membrane and showed good rejection of dye molecules. The composite membrane also demonstrated low rejection of salts, leading to the mutual separation of dyes and salts. Additionally, the membrane displayed excellent stability and anti-fouling ability.

Summary: Molybdenum disulfide (MoS2), as a transition metal dichalcogenide, consists of individual sheets stacked into a bulk-phase structure. Few-layer MoS2, similar to graphene, possesses a two-dimensional nanostructure with a large specific surface area and many unsaturated vacancies, making it promising for applications in the fields of photoelectricity and catalysis. In this study, a simple and practical method using chitosan/acetic acid (CS/HAc) solution was proposed to exfoliate bulk-phase MoS2. The method offers a new idea and approach for peeling treatment of other laminated materials and shows great potential for applications in optical and electrical fields.

Summary: A porous C3N4 microsphere with curved structure was fabricated through preassembly-calcination method, showing enhanced PMS-assisted visible-light catalysis efficiency. The synergy between PMS activation and photocatalysis mainly enhanced the non-radical pathway on MCN, which is favorable for real water systems. The enhanced performance of MCN is attributed to the curvature-induced spatially uneven distribution of electrons.

Summary: The overuse of antibiotics has resulted in the increase of antibiotic-resistant genes in bacteria. To combat this issue, a fungicide with a different antibacterial mechanism from antibiotics is needed. Quaternary ammonium salts (QASs) have shown promise as they have good antibacterial properties and can reduce the likelihood of bacteria developing drug resistance. This review focuses on the synthesis and application of different types of QASs and provides insight into their structure-function relationships, aiming to explore more applications of QASs in antimicrobial research for clinical use.

Summary: Fenton-like catalysis based on peroxymonosulfate (PMS) activation has been found effective in treating organic wastewater. However, the reduction of oxidized metal active sites in heterogeneous Fenton-like catalysts is often hindered, leading to limited catalysis efficiency. Recent studies have shown that a synergy effect between photocatalysis and PMS activation can enhance efficiency, but the understanding of this effect is still lacking. In this study, a Co/Fe bimetal-doped graphitic carbon nitride (g-C3N4) catalyst was designed, revealing the competitive role of holes and adsorbed metastable PMS* in determining the synergy effect. The optimal catalyst was obtained with a Co/Fe doping ratio of 2.5:2.5, demonstrating the potential of rational design of highly efficient photo-Fenton-like catalysts.
