Synthetic Diamonds
Diamonds are high the strength of the material existing on Earth, heat resistance, chemical, radioactive and abrasion resistance are superior to the applied research on the P-type semiconductor through applied research and Boron doped Diamond synthesis for the cutting machining coated tool It is in progress.
Diamond-like-Carbon technology
Diamond-like-Carbon(DLC) is kind of carbon film in solid state. It have diverse mechanical properties, High hardness and wear resisting quality and low coefficient of friction. This properties are effective use in industry. Our lab is studying this mechanical properties to apply friction of side bearing and display.
Graphene technology
Graphene qualities are flexible and transparent electrode. Also Graphene is zero-band gap material. But if graphene has less than 10nm range, it change band gap to open. So we can use it for transistor device. That why we can use Graphene for organic solar cell, DSSC, OLED, LCD, Field Effect Transistor, Touch Screen and bio-sensor. we are now studying graphene to use in various field.
Electro spinning technology
Electro spinning is producing fiber in micro to nano meter scale by electric field. This technique is simple and there is no limit at choose materials. Electro spinning have very diverse properties like high Specific Surface, porosity and easy to regulate the configuration and scale of fiber. By this properties we are studying polymer to use wide range of applications in industry.
Synthesis of cBN(Cubic Boron Nitride)
Cubic boron nitride (c-BN) does not exist in nature but it is a novel substance created by human. It is synthesized under high pressure and high temperature just like diamond counterpart and has the wurzite crystal structure. The tables below compare reference hardness and heat conductivity for a couple of abrasive materials. Apparently c-BN is excellent in these properties, second only to diamond, the highest. Regarding heat resistance c-BN is chemically stable to 1300° C, as compared with diamond, on which oxidization begins around 700° C. Further c-BN, as less reactive with iron, can be used as a fan abrasive material without being consumed for the working of ferrous materials. By this resistance, we are studying to apply the cBN in the tool.
