ZnO nanorods

Lili Yang Qingxiang Zhao, ITN

The aim of this project is to develop an effective way to control ZnO growth with high reproducibility (control orientation, diameter and density of nanorods) and to investigate fundamental physics involved in ZnO nanorods, nanotubes and nanodots in order to utilize their applications.

Following issues are in focus: Polariton versus diameter, length of ZnO nanorods and nanotubes, excitons such as the free exciton, bound exciton, biexciton and charge exciton depend on geometry of ZnO nanorods, nanotubes and nanodots and whispering gallery modes in ZnO nanotubes.

Atomic Force Measurements for Studies of forces Involved in Protein Folding

Daniel Aili, Fengi Tai, Thomas Ederth, Bo Liedberg, IFM

Synthetic polypeptides with controllable folding properties have been utilized as a molecular Lego for self-assembly of complex nanostructures. Applications range from nanoelectronics to biosensors. This project has been focused on understanding the assembly-mechanisms and forces involved in dimerization and folding of these polypeptides, which is essential for further development of new building nano-Lego building blocks.
