  • ws2 oil additive is the new generation of engine lubricants, specifically designed to significantly improve performance and reduce maintenance costs. It is based on unique nano technology developed at the Weizmann Institute of Science.

    ws2 powder has superior anti-friction and anti-wear properties, especially under high pressure and extreme temperature conditions. Its patented, pioneering inorganic multi-layered fullerene-shaped Tungsten Di-sulfide nano particles reduce friction and heat, thereby reducing mechanical wear. These nano particles also have the ability to create a continuous tribofilm, helping to repair damaged parts.

    The tribofilm helps prevent wear damage by coating moving parts with lubricating layers, minimizing friction and increasing load-bearing capacity for much longer cycles. This is especially efficient under extreme pressure and high temperatures, which can improve engine power and reduce downtime.

    This technology is especially effective in heavy duty gears, manual transmissions, rear and front differentials and transfer case (4x4 vehicle, trucks, tractors). It can also be used on final drive equipment such as earth moving machines and conveyors.

    Nano Extreme WS2 is an advanced surface-reconditioning nano lubricant that reduces friction in all moving components of engines. It re-smoothens abrasion cracks and crevices by combining pioneering inorganic, multi-layered fullerene-shaped, Tungsten Di-sulfide (WS2) nano particles and a special formula to minimize equipment wear under extreme pressure, creating a tenacious tribofilm that remains even after an oil change.

    WS2 is a cost-effective alternative to PTFE and Molybdenum Disulphide, allowing it to be applied in a wide variety of industrial applications. It can withstand pressures to 300,000 PSI (27 kbar) and operates in the temperature range of -270 C to +650 C, making it work much more effectively than additives like PTFE.

  • ws2 oil additive is a new kind of engine lubricant which is based on tungsten disulfide nanoparticles. It can improve the lubricating properties of a base oil and reduce friction and wear. In addition, it can increase the oil film strength.

    WS2 oil can be added to most engine oils and gear oils, and it can significantly reduce friction and wear in machinery, leading to lower operating temperatures and increased power and fuel efficiency. It also helps to extend equipment life and reduce maintenance costs.

    Low friction and anti-wear - a unique blend of high performance tungsten disulfide nanoparticles with a high surface energy that reduces friction and heat, resulting in less mechanical wear. WS2 has excellent extreme pressure performance and is highly oxidative-resistant.

    The multi-layered tungsten disulfide particles have a fullerene-like shape, which can help to reduce friction and heat. They can also exfoliate under contact pressure, forming continuous tribofilms that repair wear damages. This tribofilm is tenacious even after oil changes, extending the life of your equipment and keeping your engine running smoothly.

    Tests conducted on a Komatsu HD465-7 Dump Truck with a Cummins SAA6D 120 E-5 engine showed that adding WS2 to Total Rubio T177400 15W-40 diesel engine oil extended the engine's oil life by 43%, and reduced fuel consumption by 7%. Fuel burn rate decreased 4.7%, and rear exhaust temperature declined 4%.

    WS2 can be used in a wide range of industrial applications such as gears, manual transmissions, rear and front differentials, transfer cases (four-wheel vehicles and trucks), and final drive (tractors). Its unique nano-technology minimizes equipment wear at extreme pressure, and creates a tenacious tribofilm that remains on the engine's metal surfaces, protecting it even after oil changes.

  • titanium nitride conductivity is one of the most important applications for titanium nitride. It is used in the manufacture of a wide variety of products, including medical devices and electronics.

    Titanium Nitride is a chemically inert, refractory material that is often used to form a barrier layer between copper and other conductive materials. It also serves as a moisture-proof passivation oxide film for thin film resistors.

    It is also used as a gate electrode in metal-oxide-semiconductor (MOS) transistors and as a low-barrier Schottky diode. It is also an excellent insulator and thermal conductor.

    In addition, it can be used to coat gold jewelry and automobile trims for decoration purposes. It also improves the life of tools by 7 times over uncoated materials and reduces abrasion, wear, and galling.

    The titanium nitride market is expected to grow robustly over the forecast period, driven by rising demand for corrosion-resistant coatings and materials in various industries. However, non-uniform pricing of TiN coatings can restrain its growth.

    The titanium nitride market is primarily driven by the increasing usage of the product for the development of surgical devices and food processing equipment. The revenue of the TiN market is also supported by the growing demand for injection molding equipment and high-quality tools.

  • hafnium hydride is a non-toxic and safe compound that can be prepared by heating a metal salt with hafnium to a temperature sufficient to induce gel formation. The resulting gel can be deposited on glass or silicon substrates for use in electronic devices.

    The hcp structure of sputtered thin films is reproducible qualitatively using NR and X-ray diffraction (XRD). These thin film hydrides have the same lattice constants as bulk hydrides.

    Hydrogenation of sputtered Hf thin films by hydrogen pressure has been investigated. The hcp solid solution, formed on sputtering at high temperatures, consists of a large two-phase region separated by the d face-centred-cubic phase in which hydrogen occupies the interstitial tetrahedral sites. On further hydrogenation, a transformation takes place to the e face-centred tetragonal phase where the fcc lattice is compressed along the c axis.

    The reversible and irreversible hydrogenation of sixteen intermetallics by a partial hydrogen pressure in the range 10+3 Pa to 0.8 Pa was studied. All the compounds except for one, in which a ternary hydride was formed, have an hcp structure.

    During the hydrogenation process, the hcp structure is transformed to an fcc lattice, where the c axis is compressed and the d' axis is extended. The volume of the host metal increases by about 16% on entering the fcc phase and an additional 2.8% within it19,20.

    These results show that the reversible and irreversible hydrogenation can be easily studied in a controlled way. A single cycle of the hydrogenation can be used to determine the hcp and fcc plateau pressures as well as to identify the unloaded state of the hydride.

  • The chemical formula of nickel ii selenide is NiSe.

    This is a crystalline inorganic substance that is yellow, green or blue in color and emits hazardous fumes when heated. It is used in electroplating and as a chemical intermediary in the production of other types of nickel compounds.

    It is found in retgersite, a rare mineral that is a byproduct of copper refining. It contains one atom of nickel and one atom of sulfur and four atoms of oxygen.

    The oxidation state of the nickel in this compound is normally 2+, so it will be NiSe when you add an ion of S. It is a little tricky to figure out the chemical formula because it is ionic, so you need to know the oxidation number of the nickel and the oxidation state of the sulfide.

    Sulfate Compounds are salts or esters of sulfuric acid that contain a metal replacing one or both of the hydrogens. They are moderately water and acid soluble.

    They are also soluble in organic solutions, and sometimes both. Sulfates can be formed by a two-step displacement reaction between the sulfate and a base, such as hydrochloric acid.

    Sulfates can be toxic to aquatic organisms. Generally, they are emitted as a result of atmospheric and terrestrial activities, such as sulfide-containing minerals and volcanic activity. They can bioaccumulate in marine organisms, and may be toxic to human beings. This is especially true when people consume contaminated food or drink.
