Measurements are often more difficult than usually assessed as there are several sources of error, among them the limited accuracy of the sample thickness in TMA set-ups. Average values range from 150 to 200 · 10− 6 K− 1 [59, 115]. It may be smaller than 100 · 10− 6 K...
Measurements of the Doppler broadening of the 511 keV positron annihilation γ-quanta and the electrical resistivity are performed on the metallic glasses Fe80B20, Fe78Mo2B20, and Fe32Ni36Cr14P12B6 (Metglas ® 2605, 2605A, 2826A, respectively), In contrast to previous measurements on other ...

Two-dimensional31P homonuclear through-bond correlation MAS experiments and 2D homonuclearJ-resolved MAS measurements were performed at high spinning frequency to probe P–P and P–Se–P connectivities between the different P sites for the compounds in two glass-forming regions, P2.5Se97.5–P50Se...
measurements than on anyone else. Makers of cell phones, eyeglasses, liquid-crystal displays, and hundreds of other products [...] filmetrics.com 越来越多的公司都负担得起Filmetrics薄膜厚度测量,如手 机、镜 片、 液 晶显 示器与数以百计的其他产品制造商都能体会到我们的设备是操作简单、低成...
The glass transition temperature was determined through differential thermal analysis at a heating rate of 10 °C/min. To examine the crystalline phases in the prepared glass, we performed X-ray diffraction measurements using a RINT2100 (Rigaku, Japan) with Cu Kα radiation. The densities of the...
Instrumental mass fractionation (IMF) associated with Secondary Ion Mass Spectrometry (SIMS) measurements of oxygen isotope compositions in silicate glasses was studied using a set of 27 synthesized glasses spanning a compositionally broad range of six major oxides: SiO2, TiO2, Al2O3, total FeO (...
