Automated, low-temperature dielectric relaxation apparatus for measurement of air-sensitive, corrosive, hygroscopic, powdered samples
An automated apparatus for dielectric determinations on solid samples was designed to allow cryogenic measurements on air-sensitive, corrosive, hygroscopic, powdered samples, without determination of sample thickness, ...
High-resolution, high-sensitive ac calorimeter.
A high-resoln., high-sensitivity, automated ac calorimeter capable of heat capacity measurements of very small samples (m < 20 mg) with a temp. resoln. of a few mK in the ac mode is described. This calorimeter also can be ...
Measuring the Geometric Component of the Transition-Probability in a 2-Level System
We describe the measurement of a component of the nonadiabatic transition probability in a two-level system that depends only on the path through parameter space followed by the Hamiltonian, and not on how fast the path ...
Sodium distribution in sodium tellurite glasses probed with spin-echo NMR
We present results on the spatial distribution of sodium cations in sodium tellurite glasses as a function of sodium oxide content, obtained using a spin-echo NMR experiment. Glasses were studied with sodium oxide content ...

Explanation for the 4.8-V plateau LiCrxMn2-xO4
Using the results of photoelectron spectroscopy (PES) measurements on LiCrxMn2-xO4 we provide an explanation for the origin of the 4.8-V plateau in Li/LiCrxMn2-xO4 cells. PES shows that the d bands derived from Mn 3d e(g) ...
Photoacoustic Investigation of the Temperature and Magnetic-Field Dependence of the Specific-Heat Capacity and Thermal-Conductivity Near the Curie-Point of Gadolinium
The photoacoustic technique was used as a simple but accurate tool to simultaneously determine the specific-heat capacity C and thermal conductivity kappa of gadolinium in the neighborhood of the Curie point. One ...
Thermal conductivities of a clathrate with and without guest molecules.
The thermal conductivities of Dianin's compd. [4-(p-hydroxyphenyl)-2,2,4-trimethylchroman] and its ethanol adduct in the temp. range 20-250 K are reported. This clathrate has the same stable structure both with and without ...
Self-assembly of novel trimers using dipyrromethene ligands
Ligands comprising two dipyrromethene units linked at the beta-position have been used to prepare trimeric complexes with Zn-II and Co-II; the structure of the Zn-II complex is confirmed by X-ray analysis.
