چکیده
The d iffractometer cryostat described earlier has been modified to provide a means for controlling temperature and fo r confining the vapor in equilibrium wit h volatile samples. Materials with vapor pressures as great as 1 atmosphere (atm) can be handled without loss of insulatin g vacuu m, a nd temperatures can be controlled with an accuracy of ± 0.1 OK in t he range 4 to 20 OK dec reasing to ± 1.0 OK at 300 Ole Data on th e lattice constant an d therm Hl expansion of neon are given to demonstrate t he suitability of the apparatus for maintaining a desired temperature wh il e wo rl<ing with a volatile material.

An in-vacuum diffractometer for resonant elastic soft x-ray scattering.
We describe the design, construction, and performance of a 4-circle in-vacuum diffractometer for resonant elastic soft x-ray scattering. The diffractometer, installed on the resonant elastic and inelastic x-ray scattering beamline at the Canadian Light Source, includes 9 in-vacuum motions driven by in-vacuum stepper motors and operates in ultra-high vacuum at base pressure of 2 × 10(-10) Torr. ...

X-ray powder diffraction data for Mo2.85Al1.91Si4.81 are presented here. The new Mo2.85Al1.91Si4.81 compound was successfully prepared, using the self-propagating high-temperature synthesis (SHS) technique. The starting atomic mixture of reactant powders was Mo + 2(1 - x)Si + 2xAl with 0.2 ≤ x ≤ 0.5. The final powder compound obtained by the SHS technique was determined to be in x = 0.2; Mo(Si,...

متن کاملElectrical conductivity anomaly in silver vadadium-tellurite glasses at temperatures higher than a characteristic temperature: evidence for an ionic-nonadiabatic polaronic mixed conduction
Electrical conduction anomaly was observed in the mixed ion-polaron regime for xAg2O-40TeO2-(60-x)V2O5 glassy system with 0 ≤x≤ 50 mol%, which were prepared by common melt quenching method. For the understudied glasses, the temperature dependence of dc electrical conductivity was measured from a characteristic temperature to 380 K, which certified their semiconducting nature. The measured condu...
