ABSTRACT
We report an experimental study on the correlation spectrums between different sections of a multi-contact GaN nanowire device. Our results indicate that there exists a negative correlation between the voltage fluctuations of adjacent sections of the nanowire separated by a metal contact in the transition region between the low-frequency 1/f noise and the high-frequency white thermal noise. We suggest that this correlation is caused by the voltage fluctuation under the contact area.
ABSTRACT
The amide I bands of the deconvolved FTIR spectrum of bovine insulin, despentapeptide (B26-B30) insulin and desoctapeptide (B23-B30) insulin in D2O solution have been assigned to alpha-helix, the 3(10) helix, irregular helix, extended chains, beta-turns and other secondary structures. From the peak areas the relative contents of these structures obtained are in general agreement with those calculated from the known structures of porcine insulin and DPI in the crystalline state. The main difference in the structure of DOI with those of insulin and DPI is the shortening of the helix segment and an extended chain for the C terminal segment in the B chain.
