Analyzing Nanoscale Magnetic Materials

As the advance of technology, the manufacturing process of materials has moved forward from the scale of micrometer to sub-micrometer and nanometer. Combining nanotechnology and traditional magnetic materials, nanoscale magnetic materials can be created for applications in biomedical examination and therapy as well as data recording to increase the storage space of a computer. The topic of usin...

Polypeptide-Based Nanoscale Materials

Self-assembly has emerged as a promising technique for fabrication of novel hybrid materials and nanostructures. The work presented in this thesis has been focused on developing nanoscale materials based on synthetic de novo designed polypeptides. The polypeptides have been utilized for the assembly of gold nanoparticles, fibrous nanostructures, and for sensing applications. The 42-residue poly...

Nanoscale Luminescent Materials for Blue Light Excitation

Identifying defects in nanoscale materials.

We have developed a novel iterative experimental-theoretical technique which can identify the atomic structure of defects in many-atom nanoscale materials from scanning tunneling microscopy and spectroscopy data. A given model for a defect structure is iteratively improved until calculated microscopy and spectroscopy data based on the model converge on the experimental results. We use the techn...

Surface Chemistry in Nanoscale Materials

Although surfaces or, more precisely, the surface atomic and electronic structure, determine the way materials interact with their environment, the influence of surface chemistry on the bulk of the material is generally considered to be small. However, in the case of high surface area materials such as nanoporous solids, surface properties can start to dominate the overall material behavior. Th...
