  • Engine Oil Additive
    • Download Technology Summary  

      The product is an engine oil additive composed of nanometric tungsten disulphide (WS2) powder, nanometric molybdenum disulphide (MoS2) powder, dispersant, antioxidant and metal deactivator. The most impactful and distinctive feature of the product is the use of WS2 nanoparticles, considered one of the best lubricating materials in the industry.

      The nanoparticles, averaging 100nm-200nm in size, are created by a proprietary process that allows them to be evenly dispersed in the base oil. Actual usage shows that the nanoparticles do not agglomerate and will not block the oil filter. The nanoparticles form a protective layer on metal surfaces which reduces abrasion to friction-prone surfaces. Tests also indicate that engine oil containing WS2 nanoparticles outperform existing products in the market.

      The following are the results of tests conducted by an independent third party for a gasoline engine:

      Reduced fuel consumption by 5%-9.5%, increased engine power by 3.4%-6.8% and increased torque by 3.4%-6.9%.

      Reduced hydrocarbon emissions by 41.7% at low speed.

  • Polysaccharide-Modified Gelatin Nanoparticles
    • Download Technology Summary

      Although they possess a wide range of applications, unprocessed gelatin nanoparticles (without surface modification) encounter the problem of being phagocytosized by the mononuclear phagocyte system (MPS) in the body. Surface modification of gelatin nanoparticles is usually required to prevent phagocytosis, and this can be done through the use of synthetic polymers, generally polyethylene glycol (PEG). The process of grafting PEG over gelatin nanoparticles, however, is complex and involves the use of organic chemicals as well as toxic chemical reagents. The use of these chemicals can increase the cost of the process, endanger human health and cause environmental pollution.
      Recent research suggests that polysaccharides can be a viable material for surface modification of gelatin nanoparticles. It also has been found that polysaccharide-modified nanoparticles have low plasma protein adsorption and long circulation times.

      The invention relates to a method of preparing stable polysaccharide-modified gelatin nanoparticles and its applications. The nanoparticles are formed by a cross-linking mechanism and have a gelatin core and polysaccharide shell.

      The gelatin nanoparticles have the following benefits:

      Use of polysaccharide as a surface modifier prevents the gelatin nanoparticles from being phagocytosized , thereby providing long circulation properties in the body

      Long-term stability as nanoparticles can be preserved in water solution for a long period of time, or they can be processed to powder form

      Reduced cost as only heat and organic chemicals are used

      Possess monodispersity property

      Environmentally friendly, non-toxic and safe due to the absence of organic solvents and toxic chemical reagents in the preparation.
