Listed with other top experts in: |
|
Expert has expertise in thin and thick film coating processes, including metallic and metal oxide thin film, nano thin films, carbon nanotubes, polymer coating formulation, viscosity measurement and control, and coating methods such as dipping, spraying, web coating, CVD, sputtering, PVD, sol-gel, and spinning. He has extensive experience in film after treatment, including drying, curing, radiation curing, and curing process development. Its applications are in finishing, magnet tapes, data storage disks, medical sensors, surface lubrication, surface protection, and surface modifications.
|
|
|
Expert is well-versed in both chemical and mechanical surface characterizations. He is also capable of performing both static and dynamic friction coefficient and force measurements, tester development, testing procedures development, and friction and wear reduction by using the proper type and amount of lubricants. He has applied his expertise in medical devices such as catheter balloon guidewire operation, data storage such as magnetic tape and disk lubrication and wear reduction, energy saving, and motion speed facilitation.
|
|
|
Expert's expertise includes selecting, applying, and testing specialty lubricants (except auto engine lubricants). The interaction of lubricants and substrate surfaces, both chemically and mechanically, are critical to their performance. Physical and chemical-bound lubricants provide long-term service. Organic esters and perfluorinated polyethers play an important role in the growth of modern lubrication technology.
|
|
|
A significant portion of Expert's career is dedicated to surfaces, including their characterization, cleaning, and modification, both mechanical and chemical. These have been applied to substrate preparation, lubrication, blood nonclotting devices, biomaterials, adhesion enhancement, thin films, microelectronics, and surface-immobilized sensors in industrial and medical applications. In addition, he has extensive hands-on experience in the use of surface characterizing instruments.

|
|
Expert is very skilled in surface modification with heparin. The effect of a spacer linking between the surface and Heparin macromolecules had been studied by Expert. Heparin was covalently bonded to polymer surfaces and it showed extended anti-coagulation and anti-deposition of platelets deposition.
|
|
|
Expert's major career focus has been in polymer science and engineering, with an emphasis in application to engineering materials, biomedical materials, microelectronics, films, finishings, biosensors, inks, computer data storage films, cleaning products, dispersants, flow control agents, lubricants, hydrogels, and special monolayer films for high-tech and medical applications.

|
|
|
Expert has employed plasma technology in the development of a chemically-modified surface for multi-layered thin film coatings in medical sensors and microelectronic applications. Inorganic and metal surfaces can be cleansed and oxidized, and organic films can by functionalized by the plasma technology in oxygen, ammonia, halogen, and inert gases.
|
|
|
Expert has developed medical, optical, nano electric and electrochemical sensors to measure blood ions, pH, carbon dioxide, oxygen, and other blood chemical species. He has expertise in medical device assembling, components material selection, disposable plastics, and bonding materials. He is also familiar with the current market new development.
|
|
|
Expert notes that surfaces are active both in chemical and physical aspects. Contaminants such as gases, polutants, and foreign materials are constantly attracted onto surfaces. Surface contamination causes product failures. He can consult on these topics.
|
|
|
Expert notes that nitrile rubber is a special elastomer. Its chemical and physical structures (from copolymerization) are complicated, which affects its physical and mechanical performances. Careful selection of nitrile grades and vendors are essential for final product success. Expert can assist with this.
|
|
|
Expert has been working on Coating to kill microbes on contacting with the surface coatings. They are including polymers and nanomaterials.
|
|
|
Expert has been working on Carbon nanotube which posseses unique electrric, mechanical, optical and biological properties. Chemical and environment sensors are made of carbon nanotubes by detecting the changes of electric conductivity.
