Yu Nam Chol (pictured), PhD, associate professor and researcher at Kim Chaek University of Technology, is a member of the organizing committee and Technical Committee member of the International Conference on Materials Science. He is also a member of the International Society of Chemical Engineering of the International Association of Engineers and an honorary member of the London Journal Publisher Association of the UK.
He has presented or contributed dozens of papers at international conferences and to international science journals and reviewed papers for the conferences.
He published six SCI-class papers last year and another one in January this year.
Of them two papers attract particular interest of the academic circle.
The first paper proved that nano-ceramic materials, which can be used as an ideal NTC thermistor, can be successfully prepared by a cheap sol-gel auto combustion and the second one presents numerical data with which to design an optimized multilayer NTC thermistor by way of simulation using a finite element analysing method.
“Nano-ceramic materials prepared by sol-gel auto combustion will lower the production cost by a fourth of that by the existing method and if they are annealed for 72 hours at 550℃ in N2 atmosphere, their aging will be reduced by over 0.3 percent as compared to before. And many researchers have undertaken research projects to design optimized multilayer NTC thermistors. I applied the simulation method based on finite element analyzing method which is used for designing optimal battery to the designing of multilayer NTC thermistors and confirmed correct and satisfactory numerical values,” said Yu.
The research results are expected to be of high practical value as the NTC thermistor and multilayer NTC thermistor are widely used.
