A novel, model-based technique for finding the impedance and sensitivity of the ultrasonic planar immersion transducer in a pulse-echo setup is proposed. The resultant sensitivities from the proposed method agree well with that obtained from a three-transducer method used in calibration studies.

Cylindrical specimens may be tested advantageously by using grazing-incidence interferometry. A multiple positions test in combination with rotational averaging has recently been used to separate the surface deviations of the specimen from the interferometric aberrations. To reduce the measuring time and to check whether the results are reliable, a second procedure is now investigated, which uses the principle of the multiple positions test to determine quantities proportional to the difference quotients of the surface deviations. After numerical integration, the results can be compared with those obtained previously by rotational averaging. The measurement principle is described, and calibration results are presented.

The characterization of FluoSpheres as an internal fluorescent pressure calibrant in diamond anvil cell between 0.1 MPa and 2 GPa is reported. The effect on fluorescence of various physical and chemical parameters such as pH, temperature and salinity is investigated.

A determination of the ruby high-pressure scale is presented using all available appropriate measurements. Calibration data extend to 150 GPa.

Polarization consistent basis sets are described for the elements He, Li, Be, B, Ne, Na, Mg, Al and Ar. The basis sets for Li, Be, Na and Mg are defined based on energetic analysis and the performance for atomization energies is comparable for those systems composed of the elements H, C-F, and Si-Ar.

The quantitative study of the high power ferromagnetic resonance (FMR) saturation response for thin Permalloy films and theoretical analysis of the relevant Suhl processes over the full FMR profiles are presented.

An analytical method for evaluating proportionally constant of pickup coil is described, A comprehensive analysis of the geometric limitations for pickup coils, with emphasis on their application to long superconducting samples with both high and small demagnetization factors is also presented.
