Lastly, we provide guidelines on the design and propose testing methodologies to assess the performance of the MoS 2 for high-energy-density Li metal batteries.

Dry lubricant

Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium.[1] The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil

Applications of carbon quantum dots in lubricant additives:

Advances in lubricants are vital to the pursuit of energy efficiency and sustainable development. It is well known that the essence of lubricating oil is lubricant additives, especially the friction-reducing and anti-wear additives. Carbon quantum dots (CQDs), a novel zero-dimensional carbon-based nanomaterial, have attained growing expectations in material and chemical sciences because of

Innovation in Nanoparticle Additives for Water

Solid based lubricants include, but are not limited to, graphite, WS2 and MoS2 powders/coatings. Oil-based greases are a good example of a semi-solid lubricant. A liquid lubricant with typically 90 percent oil and up to 10 percent additives serves for reduced friction and wear, and resistance to corrosion whereas nitrogen and helium are the typical gaseous lubricants.

Molybdenum Disulfide (MoS2) Powder

Crystal structure is Hexagonal Lamellar and is similar to graphite, Boron Nitride and Tungsten Disulfide. It also has excellent film forming properties and is an excellent lubricant in moisture free environments below 400 C. MoS 2 offers excellent lubricity properties in inert atmospheres and under high vacuum where other conventional lubricants fail.

Additives for Lubricants and Mold Release – BYK

BYK offers different additives for industrial lubricants. Our defoamers can be used to prevent foam generation, and to release air from the lubricant. BYK wetting and dispersing additives can be used to suspend solid additives (e.g. graphite, MoS2). Higher solid

Synthetic Fabrication of Nanoscale MoS2

Application of solid lubricating molybdenum disulfide

The solid lubricant can be firmly bonded to the surface of the substrate by using the bonded solid lubricating film, thereby effectively preventing the adhesion of the metal parts. It can achieve effective lubrication in special environments where conventional grease is not suitable for use, so it is widely used in environments such as vacuum, high and low temperature, inflammable and
