“…As one of the most promising 2D materials, transition metal dichalcogenides (TMDs) have attracted significant attention due to their exceptional optical, electronic, chemical properties, and gained wide‐ranging applications such as field–effect transistors, energy storage, electrocatalysis, and so on. Current strategies for the synthesis of 2D TMDs primarily include chemical exfoliation, chemical vapor deposition (CVD), and liquid‐phase syntheses .…”

2D transition metal dichalcogenides (TMDs) are well suited for energy storage and field-effect transistors because of their thickness-dependent chemical and physical properties. However, as current synthetic methods for 2D TMDs cannot integrate both advantages of liquid-phase syntheses (i.e., massive production and homogeneity) and chemical vapor deposition (i.e., high quality and large lateral size), it still remains a great challenge for mass production of high-quality 2D TMDs. Here, a molten salt method to massively synthesize various high-crystalline TMDs nanosheets (MoS 2 , WS 2 , MoSe 2 , and WSe 2 ) with the thicknesses less than 5 nm is reported, with the production yield over 68% with the reaction time of only several minutes. Additionally, the thickness and size of the as-synthesized nanosheets can be readily controlled through adjusting reaction time and temperature. The assynthesized MoSe 2 nanosheets exhibit good electrochemical performance as pseudocapacitive materials. It is further anticipates that this work will provide a promising strategy for rapid mass production of high-quality nonoxides nanosheets for energy-related applications and beyond.

“…Among them, 1T-WS 2 consists of six sulfur atoms with the tungsten atom in the center and in a unit cell, the crystal structure of 1T-WS 2 repeats the stack formation in a single manner. The conductivity of 1T-WS 2 (metallic phase) is ~ 10 5 times higher than that of 2H-WS 2 , which makes it more competitive in electrochemical applications [22]. Unfortunately, the application of 1T-WS 2 is limited by the metastable nature and the 1T phase could convert to the 2H phase under high-temperature conditions (~ 95-100 °C) [23].…”

Energy and environmental issues received widespread attentions due to the fast growth of world population and rapid development of social economy. As a transition metal dichalcogenide, tungsten disulfide (WS 2) nanomaterials make important research progress in the field of energy conversion and storage. In view of the versatile and rich microstructure of these materials, the modification and controllable synthesis of WS 2 nanomaterials also inspire a research interest. This review mainly focuses on WS 2-based nanomaterials in the application of energy conversion and storage as well as discusses some basic characteristics and modification strategies of them. Finally, the research progress of WS 2-based nanomaterials is reviewed and some prospects for future research directions are proposed. This review is expected to be beneficial to the future study of WS 2 nanomaterials used in the field of energy conversion and storage.

“…With the use of local heat agents, heat can be more effectively targeted to cancer cells rather than affect the healthy cells surrounding tumors, taking advantage of the strong absorbance of NIR to local heating agents. In recent years, various nanoparticles have been developed as efficient local heating agents, such as magnetic nanoparticles, gold nanoparticles, carbon nanotubes, and graphene/graphene oxide (GO) nanosheets.…”

Photothermal therapy using near-infrared radiation and local heating agents can induce selective tumor ablation with limited harm to the surrounding normal tissue. Graphene sheets are promising local heating agents because of their strong absorbance of near-infrared radiation. Experimental studies have been conducted to study the heating effect of graphene in photothermal therapy, yet few efforts have been devoted to the quantitative understanding of energy conversion and transport in such systems. Herein, a computational study of cancer photothermal therapy using near-infrared radiation and graphene is presented using a Monte Carlo approach. A three-dimensional model was built with a cancer cell inside a cube of healthy tissue. Functionalized graphene nanosheets were randomly distributed on the surface of the cancer cell. The effects of the concentration and morphology of the graphene nanosheets on the thermal behavior of the system were quantitatively investigated. The interfacial thermal resistance around the graphene sheets, which affects the transfer of heat in the nanoscale, was also varied to probe its effect on the temperature increase of the cancer cell and the healthy tissue. The results of this study could guide researchers to optimize photothermal therapy with graphene, while the modeling approach has the potential to be applied for investigating alternative treatment plans.
