In our effort to develop metal cutting as a high strain rate test, we are interested in mapping the damage distribution over the primary shear zone (PSZ). The approach is to quantify the modulus degradation via nanoindentation and use this as a measure of damage. It is shown that the hardness of the material increases and the modulus degrades as it shears(More)
The combination of high-brilliance synchrotron radiation with scanning tunneling microscopy opens the path to high-resolution imaging with chemical, electronic, and magnetic contrast. Here, the design and experimental results of an in-situ synchrotron enhanced x-ray scanning tunneling microscope (SXSTM) system are presented. The system is designed to allow(More)
The FT-IR and FT-Raman spectra of 5-chloro-2-(3-chlorophenylcarbamoyl)phenylacetate were studied. The vibrational wave numbers and corresponding vibrational assignments were examined theoretically using the Gaussian 03 set of quantum chemistry codes and the normal modes are assigned by Potential Energy Distribution calculations. The synthesis, elemental(More)
FT-IR and FT-Raman spectra of 4-chloro-2-(3,4-dichlorophenylcarbamoyl)phenyl acetate were recorded and analyzed. Synthesis and elemental analysis are also reported. The vibrational wavenumbers of the compound have been computed on the basis of density functional theory using B3LYP/6-31G* basis set. The predicted infrared intensities and Raman activities are(More)
