Journal Club November 2007: Surface Effects on Nanomaterials
Nanoscale materials, including thin films, quantum dots, nanowires, nanobelts, etc – are all structurally unique because they have a relatively high ratio of surface area to volume ratio. This increase in surface area to volume ratio is important for nanomaterials because wide and unexpected variations in mechanical and other physical properties, such as thermal, electrical and optical, have been found to scale in some proportion to increase in surface area to volume ratio.

The story behind the proof of Fermat's Last Theorem
When I came to the institute, my collaborator Kay invited me for a dinner in the new town together with his friend Thilo and other guys. The city is wisely divided into two functioning areas, old town and new town. All the ancient buildings like King’s summer palace, women’s church and opera house are in the old town; while the restaurants, bars and other modern buildings are in the new town. Each is in harmony with its environment and cultural atmosphere.

Multiaxial behavior of nanoporous single crystal copper: a molecular dynamics study
The stress-strain behavior and incipient yield surface of nanoporous single crystal copper are studied by the molecular dynamics (MD) method. The problem is modeled by a periodic unit cell subject to multi-axial loading. The loading induced defect evolution is explored. The incipient yield surfaces are found to be tension-compression asymmetric. For given void volume fraction, apparent size effects in the yield surface are predicted: the smaller behaves stronger.
Crack formation in thin film during deposition process
Dear Researchers,
I am a research student, "Surface modification of materials" is my research topic. I joined your site to discuss the crack propagation during thin film deposition.
