Indonesia
Largest archipelago in the world ( a total of more than 17,508islands)
Fifth largest population in the world. (Indonesians number
190 million and are basically of Malay and Polynesian stockcomprising of 300 ethnic groups and subgroups having theirown tradition)
Indonesia has two seasons, the dry season from June toOctober and the rainy season from November to March. There
are occasional showers during the transitional periods and thegeneral maximum temperature is 33°C (62°F) and the generalminimum 21°C (41°F). Humidity is high at all times.

Motivation To Join Double Degree Program atOsaka University
1. “Double Degree”
2. “One who treads a path in search of knowledge has his path to Paradise
made easy by God.” – Prophet Muhammad (No.1 most influential people in theworld chosen by Michael H. Hast, from the book 100 most influential people in the world)

3. “The world is a book and those who do not travel read only one page.” –St. Augustine of Hippo (early theologian and philosopher whose writings influenced thedevelopment of Western Christianity and Western philosophy)

4. “All travel has its advantages. If the passenger visits better countries, hemay learn to improve his own. And if fortune carries him to worse, he
may learn to enjoy it.” – Samuel Johnson : A Journey to the Western Islands of Scotland andThe Journal of a Tour to the Hebrides

5. “No guts, no glory,” – "Die Hard: With a Vengeance" (1995).

Motivation Background• Enhanced mechanical properties•

Bending strength = 689.6 ± 29.1 MPa (Alumina : 330MPa)•Fracture toughness = 5.90 ± 0.27 MPa·m1/2 (Alumina :3.5 MPa·m1/2 )• CNT/Ceramics composites has strong load transfer .
• Explanation of interfacial nature between CNTs andthe ceramics matrix is far from satisfactory.

First-principles study of Interfacial Interaction
between Carbon Nanotube and Al2O3 (0001)
Abstract
The calculation result shows that the binding energy of CNT
and clean Al2O3 (0001) decrease as the diameter of CNT
increase. The structures of the CNT and Al-terminated Al2O3(0001) do not drastically change from those before adsorbing.
Carbon atoms of CNT interacted with the topmost aluminum
atom of Al2O3 (0001) by forming covalent bonding. In the caseof the O-terminated Al2O3 (0001), small-diameter CNTs havestrong interaction, which comes from opening of CNTs
catalytically induced by the O-terminated surface and thesubsequent formation of mixed covalent-ionic bonding
between carbon and oxygen atoms.
