The bicyclo [3, 3, 1]nonane ring system has been gaining keen interest not only from the chemistry itself, but also from the point that this system is of the main structural feature of the lycopodium alkaloids which are acetyl cholinesterase inhibitors.
A series of subsequent reactions, particular functional groups in different position of the ring gave different target structures[2].

Introduction Since the 1990s, with depth study of nanometer material and Nanotechnology by people, discovered that unique structure of certain nanometer materials enable it to have the special tribological performance, and nanometer lubricant additives that are made by these nanoparticles can greatly improve anti-friction and anti-wear performance for lubricants, and find new ways of settlement for the problems that been not able to solve for a long time in the area of lubricants.

Study on Synthesis of IPDI-based Waterborne Polyurethane Linlu Zhenga and Lu Chenb Department of Chemistry, Fujian Province University azhenglinlu666@163.com,bchenlu@163.com Keywords: Waterborne Polyurethane, Synthesis, IPDI.
IPDI is symmetrical in structure and exhibits the large molecular weight, saturated vapor pressure and low toxicity characteristics.

The decrease of both the crystal field strength and band gap with increasing Ga3+ content was found by means of electronic band structure calculations from first principles in Y3GaxAl5-xO12:Ce (x = 0 – 5) [14].
