The discovery of graphene ignites a great deal of interest in the research and advancement of two-dimensional (2D) layered materials. Within it, semiconducting transition metal dichalcogenides (TMDCs) are highly regarded due to their exceptional electrical and optoelectronic properties. Tungsten disulfide (WS) is a TMDC with intriguing properties, such as biocompatibility, tunable bandgap, and outstanding photoelectric characteristics. These features make it a potential candidate for chemical sensing, biosensing, and tumor therapy. Despite the numerous reviews on the synthesis and application of TMDCs in the biomedical field, no comprehensive study still summarizes and unifies the research trends of WS from synthesis to biomedical applications. Therefore, this review aims to present a complete and thorough analysis of the current research trends in WS across several biomedical domains, including biosensing and nanomedicine, covering antibacterial applications, tissue engineering, drug delivery, and anticancer treatments. Finally, this review also discusses the potential opportunities and obstacles associated with WS to deliver a new outlook for advancing its progress in biomedical research.

The development of environmentally friendly solid lubricants with exceptional wear resistance is imperative to address the escalating environmental concerns and performance limitations of conventional lubricants in demanding tribological applications. This study systematically investigated the wear resistance of hydroxypropyl methylcellulose (HPMC)/tungsten disulfide (WS)/graphene composites under normal applied loads (2 and 4 N) and varying solid lubricant contents (stoichiometric ratios of 0.2 referred to as CWG-0.

2D materials have emerged as promising candidates for next-generation field-effect transistors (FETs) owing to the atomically thin geometry and excellent electrostatic gate control. Here, double-gate vertical sidewall FETs based on chemical vapor deposition-grown monolayer WS are demonstrated and, for the first time, report vertical multi-channel nanosheet FETs (NSFETs). By implementing a dual-step sidewall profile, steep SiO surfaces are obtained, which enabled seamless WS adhesion and contributed to enhanced device yield.

Smart windows automatically adjust their properties to control infrared (IR) radiation which helps with saving energy by reducing the need for heating and cooling. In the current study, we use vanadium dioxide (VO), a phase change material that in temperatures above 68 °C behaves as a metal, to design smart windows. In its metallic phase, VO transmits less IR than would be expected from a smart window.

Tungsten disulfide (WS), a two-dimensional layered material with favorable electronic properties, has been explored as a promising negative electrode material for calcium-ion batteries (CIBs). Despite its use in monovalent systems, its performance in divalent Ca intercalation remains poorly understood. Herein, a combined theoretical and experimental framework is used to elucidate the electronic mechanisms underlying Ca intercalation.

We present a highly resource-efficient Close-Space Sublimation (CSS) approach, along with versatile one-step and two-step process designs, for the controlled synthesis of a wide range of tungsten (sub)oxide (WO) and tungsten disulfide (WS) nanostructures. By applying a simple sublimation model and leveraging graded CSS flux profiles in conjunction with experimentation, we accelerate process discovery and establish CSS flux and substrate temperature as key parameters governing nanostructural formation. Our CSS methodology enables the synthesis of W (sub)oxide structures within process times of less than 10 minutes, a significant improvement over the hour-long durations typically required in conventional hot-wall furnace systems.
