Abstract The temperature dependence of the optical constants materials (refractive index, absorption and extinction coefficients, dielectric function) can be determined with spectroscopic ellipsometry over a broad range temperatures photon energies or wavelengths. Such results have practical value, for example applications at cryogenic elevated temperatures. gaps their broadenings also provides...

One way to determine condition damage Pavement Condition Index (PCI) method. purpose this study determine, identify calculate value that occurs using PCI method know handling used PCI, results field analysis values calculated by method, recommendations for repairs Asph...

Point defects in NiAl and other structural intermetallics have been studied using perturbed angular correlation of gamma rays (PAC), by which signals are detected from antisite atoms and/or lattice vacancies in the first few atomic shells of probe atoms. For samples of quenched NiAl having 50 to 54 at.% Ni, site-fractions of Ni-vacancies (proportional to the vacancy concentration) were found to...
