Enhanced superelasticity of nanocrystalline NiTi/NiTiNbFe laminar composite

Quantum Simulation of Nanocrystalline Composite Thermoelectric Properties

For the past few years, nanoscale structures have been proposed and investigated experimentally for their enhanced thermoelectric properties over bulk materials. These structures offer several advantages: 1) increased local density of states, which can improve the Seebeck coefficient and 2) reduced thermal transport due to phonon confinement and increased scattering. Recently, nanocrystalline c...

The efficiency of a thermoelectric material is measured by the figure of merit ZT, which is inversely proportional to the thermal conductivity. Superlattice structures often have a reduced thermal conductivity because of the intr...

Optical nonlinearity of nanocrystalline Au/ZnO composite films.

The third-order nonlinear optical susceptibilities, chi(3), of composite films consisting of nanocrystalline Au and ZnO particles were investigated by use of a degenerate four-wave mixing scheme. The maximum value of chi(3), measured at a laser wavelength of 532 nm and a pulse duration of 70 ps, was approximately 2 x 10(-6) esu. Also, this chi(3) value was achieved with small absorption (the su...

Characterization of Nanocrystalline Si-MCMB Composite Anode Materials

Laminar Tendon Composites with Enhanced Mechanical Properties.

PURPOSE A strong isotropic material that is both biocompatible and biodegradable is desired for many biomedical applications, including rotator cuff repair, tendon and ligament repair, vascular grafting, among others. Recently, we developed a technique, called "bioskiving" to create novel 2D and 3D constructs from decellularized tendon, using a combination of mechanical sectioning, and layered ...
