“…Two-dimensional (2D) materials, such as graphene, transition metal dichalcogenides (TMDs), phosphorene, tellurene, and Mxene, have attracted much attention for various biological applications due to their unique properties including low cytotoxicity, big surface area, high chemical stability, and excellent thermal conductivity and electron mobility [99,[111][112][113]. Especially, graphene-based materials and TMSs have shown bright prospects for antibacterial applications [85,112,114].…”

Globally, millions of people die of microbial infection-related diseases every year. The more terrible situation is that due to the overuse of antibiotics, especially in developing countries, people are struggling to fight with the bacteria variation. The emergence of super-bacteria will be an intractable environmental and health hazard in the future unless novel bactericidal weapons are mounted. Consequently, it is critical to develop viable antibacterial approaches to sustain the prosperous development of human society. Recent researches indicate that transition metal sulfides (TMSs) represent prominent bactericidal application potential owing to the meritorious antibacterial performance, acceptable biocompatibility, high solar energy utilization efficiency, and excellent photo-to-thermal conversion characteristics, and thus, a comprehensive review on the recent advances in this area would be beneficial for the future development. In this review article, we start with the antibacterial mechanisms of TMSs to provide a preliminary understanding. Thereafter, the state-of-the-art research progresses on the strategies for TMSs materials engineering so as to promote their antibacterial properties are systematically surveyed and summarized, followed by a summary of the practical application scenarios of TMSs-based antibacterial platforms. Finally, based on the thorough survey and analysis, we emphasize the challenges and future development trends in this area.

“…[24,210] In the CVD process, the substrate is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired materials thin film deposit. [30,211] Additionally, one or more precursors can also selectively be used to react with the source material allowing for it to be deposited on the substrate. Polymer based organic thin films such as poly(tetrafluoroethylene) and fluoropolymer have been synthesized with this technique.…”

MXenes are a rapidly growing family of 2D materials. Their unique combination of metallic conductivity, hydrophilicity, and highly charged surfaces endow them with excellent electrochemical performance. Appropriate surface functional groups determine their semiconducting properties. The wide selection of various MXene structures and surface functional groups enable tunable work functions and bandgaps, making them prime candidates for many optoelectronic applications. In addition, the discovery of 2D organic semiconductors having single molecular thickness has also greatly attracted research attention due to their optical, electronic, optoelectronic, and mechatronic properties. Moreover, the formation of MXenes/organic 2D heterostructures enables many interesting phenomena in the 2D quantum limit to be observed. This review aims to increase motivation toward the investigation of newly emerging MXenes, 2D organic materials, and their combinational heterostructures. It overviews recent progress in the fundamental investigations of the optical, electronic, and optoelectronic properties in isolated 2D MXenes and organic materials; then, highlights the major importance of 2D MXene/organic heterostructures for applications in exciton-polariton lasers, light emitting devices, wearable electronics, and spintronic devices. The review aims outlines a future roadmap for 2D MXenes, organic materials, and their heterostructures for advanced nanotechnology applications.

“…The bonding P z orbitals from S build up some part of CBM, whose downward shift originates from the reduction of interlayer distance as well as enhanced overlap (Figure 6c). [17,[168][169][170] Interestingly, in contrast with multilayer MoS 2 , the metallization critical pressure for WS 2 is higher, which is ascribed to the layer modifications of the electronic and transport properties. [17,19] Also, WS 2 demonstrates a progressive drop in resistivity with pressure, which differs from the sudden drop of MoS 2 , revealing the slow tuning process of their electronic structure and bandgap.…”

2D materials possess wide-tuning properties ranging from semiconducting and metallization to superconducting, etc., which are determined by their structure, empowering them to be appealing in optoelectronic and photovoltaic applications. Pressure is an effective and clean tool that allows modifications of the electronic structure, crystal structure, morphologies, and compositions of 2D materials through van der Waals (vdW) interaction engineering. This enables an insightful understanding of the variable vdW interaction induced structural changes, structure-property relations as well as contributes to the versatile implications of 2D materials. Here, the recent progress of high-pressure research toward 2D materials and heterostructures, involving graphene, boron nitride, transition metal dichalcogenides, 2D perovskites, black phosphorene, MXene, and covalent-organic frameworks, using diamond anvil cell is summarized. A detailed analysis of pressurized structure, phonon dynamics, superconducting, metallization, doping together with optical property is performed. Further, the pressure-induced optimized properties and potential applications as well as the vision of engineering the vdW interactions in heterostructures are highlighted. Finally, conclusions and outlook are presented on the way forward.
