Events for 5 December 2018

Prof. Eiji Ōsawa: NANODIAMOND: A NEW ENERGY MATERIAL

1:00pm, PH30
'One of the longest pending problems in science, identification of detonation nanodiamond (DND) discovered in 1963, is finally solved. The notorious tight aggregation in DND could be destroyed by attrition milling assisted by Wigner-Seitz theory of interparticle distance, Taguchi’s method of quality engineering and an interpretation of LDI-TOF-MS. The primary particles of DND, with diameter of 2.6±0.5nm, proved to have graphene oxide patches on the surface, extensively disordered diamond phase near the surface, and a cube-shaped diamond single crystal consisting of exactly 1000 carbon atoms. Total number of carbon atoms in a DND is predicted to be 1670 by both SCC-DFTB calculations and by mass analysis. DND is by no means a simple nano-version of large diamond crystals, but a novel hybrid nano-carbon consisting of "sp2, sp2+x (0 We are currently exploring its applications taking advantage of high sphericity, hardness and chemical stability in DND. In this lecture two of the most promising experiments will be mentioned: (1) toughening of solid materials by dispersing DND, (2) and generation of zero-friction lubrication liquid (DND dissolves well in water and a few organic solvents like ethylene glycol EG). Taking advantage of these remarkable results we will briefly talk about a realistic plan to reduce emission of green-house gases by stopping the abuse of steel for transportation equipment like cars and airplanes. This goal may be reached by replacing steel with, for an example, DND-dispersed plastics like PET. Moving machines made from the tough plastics may be lubricated by, for an example with dilute DND solution in EG, wherein DND particles work as rolling nano-spacers to produce virtually frictionless systems. Steel machines and lubrication oils are the last giant ‘necessity evils’ still wandering in our modern society.'

Biography
'Eiji Osawa is emeritus professor of computational chemistry at Toyohashi University of Technology, Japan, noted for his prediction of the C60 molecule in 1970. Osawa received his Masters of Engineering in chemistry from Kyoto University Department of Industrial Chemistry and then became an engineer at Teijin Co. Ltd. In 1964, he returned to Kyoto University and earned a Doctorate of Engineering in chemistry. After three years of postdoctoral work at the University of Wisconsin, Princeton University and the State University of New York at Stony Brook, in 1970 he became an assistant professor at Hokkaido University. In 1990, Osawa became a full professor at Toyohashi University of Technology, where he retired in 2001. Upon his retirement, assisted by Futaba, Co., Ltd., Osawa started the research and development company Nano-Carbon Research Institute, Ltd.'

Dr Ning Jia: Something about data in deep learning

1:00pm, E102

People start to believe that deep learning models can approximate any function, according to the ‘Universal Approximation Theorem’. However, when businessmen come to your front door and offer you projects, think twice before being captivated by their charisma or shinning golds, simply because you never know what kinds of data they will offer for the problems to be solved, and data matters. In this talk I will present you some experiences I gathered during the past years, including the data we dealt with, the approaches we tried, and the problems we encountered.
