With the rapid advancement of science and technology, sensors, as the core components for information acquisition, have their performance directly determining the technological progress and application outcomes in numerous fields. Be it smart wearable devices, environmental monitoring systems, medical diagnostic instruments, or industrial automation production lines, sensors play an indispensable role. As the requirements for sensor performance continue to rise, researchers are dedicated to exploring novel sensitive materials. Tungsten disulfide nanosheet (WS? nanosheet) has demonstrated remarkable application potential in the…

In daily life and industrial production, the operation of mechanical equipment relies on the support of lubricating materials. Lubricating materials play a crucial role as they can reduce friction and wear between mechanical components, lower energy consumption, and extend the service life of equipment. In recent years, tungsten disulfide nanosheet (WS? nanosheet), as a new type of lubricating material, has gradually become a “star material” in the lubrication field, thanks to its unique structure and excellent properties. Tungsten disulfide nanosheet…

Tungsten disulfide nanosheet (WS? nanosheet) consists of tungsten and sulfur. Its structure resembles a sandwich, with one or more layers of tungsten atoms sandwiched between two layers of sulfur atoms, and these layers are held together by weak van der Waals forces. This unique layered structure endows the WS? nanosheet with many excellent physical and chemical properties, making it highly effective in the lcatalysis field. I. As a Catalyst in Petroleum Processing During petroleum processing, impurities such as sulfur and…
