Tungsten Sputtering Targets and Applications

Tungsten is a chemical element with symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone.
Tungsten sputtering targets can be used in various applications like light bulb filaments, X-ray tubes, electrodes in gas tungsten arc welding, superalloys, and radiation shielding. Tungsten has high density and hardness and this make it useful for military applications in penetrating projectiles. Tungsten compounds are also often used as industrial catalysts.
Also there are different applications that you may use tungsten sputtering targets to obtain uniform films. Now let's have a look at a research done by using tungsten sputtering targets.
As all we may know there is an increasing interest in solid-state thermal-to-electricity energy conversion concepts, such as thermophotovoltaic (TPV), solar TPV, and solar-thermal energy conversion systems. This has led to new investigation and fabrication of refractory metal two-dimensional (2D) photonic crystals (PhCs). These nanostructured surfaces show good optical and mechanical properties at high temperatures and act as selective emitters to increase the efficiency of the thermophotovoltaic cell.
An integrated PhC thermophotovoltaic system would be advantageous with the properties of simplifying the system integration and increasing the fabrication simplicity. A tungsten coating could be used as a functional layer on different substrates and matched to the system’s needs, decoupling the requirements of the functional layer and the substrate.

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%)  can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
