GaN nanowires with diameters of 50 nm to 250 nm, grown by catalyst free molecular beam epitaxy, were characterized by photoluminescence (PL) and cathodoluminescence (CL) spectroscopy at temperatures from 3 K to 295 K. Both as grown samples, which contained

In Pulsed-Laser Deposition (PLD), there are many processing parameters that influence film properties which may be studied such as substrate-target distance, background reactive gas pressure, laser energy, substrate temperature and composition in multi

The dispersion of nanotubes in solution is necessary in order to achieve the goal of sorting and manipulating nanotubes by length and type and to then prepare high quality monodisperse samples. A necessary step is the proper characterization of the

Urethane dimethacrylate (UDMA), an oligomeric poly(ethylene glycol) UDMA (PEG-U) and a blend of UDMA/PEG-U were chosen as model systems for introducing both hydrophobic and hydrophilic segments and a range of compliances into their derived polymers

We have used site-specific x-ray photoelectron spectroscopy (SSXPS) to measure chemical bonding, matrix element, and many-body effects in the x-ray photoelectron spectra of Corundum V2O3. Significant covalent bonding in both the upper and lower lobes of
The 2006 Materials Research Society (MRS) Fall Meeting took place in the Hynes Convention Center and the Sheraton Boston Hotel, starting the weekend following the Thanksgiving Holidays from November 26 to December 1. This large-scale meeting included forty

Ti K and Ti L2,3 edge x-ray absorption fine-structure near-edge spectra of SrTiO3 thin films grown coherently on Si(001) reveal the presence of a ferroelectric (FE) distortion at room temperature. This unique phase is a direct consequence of the
Dental composites are widely used yet still face challenges including incomplete conversion, polymerization shrinkage, and poor adhesion to tooth structures. High-throughput techniques to quickly assess several material properties in a combinatorial manner
All cells experience strain under physiological conditions. However, experiments that are performed under macroscopic strain conditions prevent a direct correlation of applied strain to cell behavior. Our focus is to measure the local stress/strain

New inorganic type II clathrates with Ag atoms substituting for framework Ge atoms, Cs8Na16AgxGe136-x (x = 0, 5.9, and 6.7), have been synthesized by reaction of the pure elements at high temperature. Structural refinements have been performed using single

Bimolecular self-assembled monolayers (SAMs) of aromatic and aliphatic chlorosilanes were self-assembled onto silica and their characteristics were established by contact angle measurement, near-edge X-ray adsorption fine structure spectroscopy, and

There is a need for experimental techniques that allow the simultaneous imaging of cellular cystoskeletal components with quantitative force measurements on single cells. A bioMEMS device has been developed for the application of strain to a single cell
