Tungsten Disulfide Sputtering Targets and Applications

Tungsten disulfide is the chemical compound with the formula WS2. It occurs naturally as the rare mineral tungstenite. Tungsten disulfide is a component of certain catalysts used for hydrodesulfurization and hydrodenitrification.
Now let's take a look how Tungsten Disulfide (WS2) Sputtering Targets (Size:3'' ,Thickness:0.125'' ,Purity:99.9%)  can be used. We all know that as the development of science and technology, especially flourishing development of space technology, the requirement of lubricating material has been increasing accordingly.
Development high-performance solid lubricating material has been exigent problem. Transition metal dichalcogenides are layered semiconductors. They have been extensively studied in the form of thin films for their potential applications in photovoltaic solar cells. These are layered compound semiconductors and crystallize in the hexagonal form P63/mmc. Each layer consists of metal layer sandwiched between two chalcogen layers in a trigonal prismatic structure. They exhibit in-plane strong covalent bonds between the metal and chalcogen atoms and weak Van der Waals type interactions between the layers. In recent decade, some transition metal dichalcogenides, such as tungsten disulphide and molybdenum disulfide, are well known for their solid lubricating behavior and used for solid lubricants due to their extreme degree of anisotropy of the layered crystal structures. Under a shearing force the basal planes slide back and forth over one another by intracrystalline slip and transfer to the rubbing counterface. As a late-model excellent solid lubrication films tungsten disulfide films performance is better than classical molybdenum disulfide films in some aspects. So the tribological behavior of tungsten disulfide films has been paid more and more attention. We can obtain tungsten disulfide thin films by some different methods, but in laboratory the RF magnetron sputtering is the most efficient method. As the deposition parameters different, properties of tungsten disulfide thin films obtained by RF magnetron sputtering are inevitable different.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product. Figure: Single Walled Carbon Nanotube (SWCNT) It ha...
