Nanoparticle assemblies and interactions
Silica nanoparticles coated with functionalized organosilane molecules are used as substrates for the formation of assemblies of gold nanoparticles. In an assembly of nanoparticles, the optical response of each nanoparticle ...
The synthesis and high pressure behavior of nanoquartz
This work describes the first chemical method for the preparation of quartz nanocrystals. Microscopic characterization to evaluate phase purity, size distribution and extent of aggregation is performed. In addition, pressure ...
Science of single-wall carbon nanotubes: Purification, characterization and chemistry
Characterization of raw nanotube materials produced by different methods is demonstrated. Depending on the production methods, tubes of different diameters can be produced. Purification of single wall carbon nanotubes ...
Chemistry of nanostructured carbon: I. Fluorination, cutting and derivatization of single-wall carbon nanotubes; II. Fluorination and characterization of polymeric carbon 60
Purified HiPco SWNTs have been fluorinated with elemental fluorine under various conditions to control the stoichiometry of the resultant Fluorotubes. The partially fluorinated SWNTs with stoichiometry CFx (x ≤ 0.3), ...
Thermophysical property measurements at high temperatures for liquid metal alloys and gadolinium oxide-doped uranium dioxide samples
New techniques for obtaining various thermophysical properties, i.e., densities and incremental enthalpies of selected materials at high temperatures have been developed with emphasis on the utilization of levitation ...
Clusters as models of bulk surfaces and novel materials
Studies on gas phase clusters show that common ground exists between clusters and bulk surfaces such that clusters can serve as models of bulk surfaces. Several cluster systems are studied to probe this cluster-surface ...
