Chemical Shift for Thermally Oxidized Silicon as Measured by ESCA

Chemical properties and cytotoxicity of thermally oxidized oil.

Heated frying oils with different chemical properties in terms of AV (acid value), POV (peroxide value), COV (carbonyl value), and contents of polar compounds (PC) and triacylglycerol (TG), as well as color and odor, were obtained. Male Wistar rats were fed ad libitum for 12 weeks a powdered diet (AIN93G; no fat) containing 7 wt% of fresh oil (control) or one of the frying oils described above....

Effect of grain alignment on interface trap density of thermally oxidized aligned- crystalline silicon films

Band structure of silicon as measured in extended momentum space

Direct measurement of the wave function or at least the modulus squared of the wave function, the spectral function is an important goal in electron spectroscopy. This requires a state-selective i.e., energy resolved measurement of the momentum density in all of momentum space, not just the reduced Brillouin zone. Photoemission has been used very successfully to measure dispersion, mainly in th...

C(alpha) chemical shift tensors in helical peptides by dipolar-modulated chemical shift recoupling NMR.

The C(alpha) chemical shift tensors of proteins contain information on the backbone conformation. We have determined the magnitude and orientation of the C(alpha) chemical shift tensors of two peptides with a-helical torsion angles: the Ala residue in G*AL (phi = -65.7 degrees, psi = -40 degrees), and the Val residue in GG*V (phi = -81.5 degrees, psi = -50.7 degrees). The magnitude of the tenso...

Wavelength tracking with thermally controlled silicon resonators.

We experimentally demonstrate feedback controlling of the resonant wavelength of a silicon dual-ring resonator. The feedback signal is the difference in optical scattering from the two coupled microring resonators, and the control mechanism is based on thermo-optic tuning with micro-heaters. This control scheme keeps the central wavelength of the resonator aligning with the input wavelength, wh...
