Results show that the dispersing stability of nanodiamond modified with surfactants YS-1 and SB-18 simulta-neously is much better than those modified with either of them because of synergism of the surfactants. And the particle size distribution in the system can be improved remarkably after the adoption of hyperdispersants such as SA-E and SA-F. Anchoring groups of those hyperdispersants can be bonded with the particle surface by chemical and/or hydrogen bonding and their soluble chains are well compatible with the dispersion media. As a result, the particles are uniformly distributed in the system owing to the steric stabilization. A very stable clean-oil based nanodiamond suspension with an average particle size of around 53.2 nm was prepared.展开更多

Following the vigorous advocacy of the U.S. President Obama and China's President Xi, PM has now become a hot topic of common concern worldwide. PM does not merely refer to the skill set level but rather a comprehensive medical methodology. Hence, there is PM that builds on the analytical methodology of Western medical system as well as PM that builds on Chinese medicine (CM). The differences between the two systems, fundamentally speaking, are the differences in methodology to describe the body constitution that based on reductionism and holism. Today, as science advances to complex systems, the mainstream analytical reductionism advances to the holistic synthesis era, it is imperative to introduce CM's holistic body constitution to the modern medical system in order to progress to PM. PM with its foundation on holistic body constitution, is a medical system that integrates Western medicine and CM, is the highest attainment of "PM" in the future.展开更多
