RESUMO
A hybrid pressure cell was fabricated from commercially available copper-beryllium and custom-made Ni-Cr-Al Russian alloy, tailored for usage as a reaction vessel supplying a volume of about 400 mm3. In order to directly (in situ) monitor pressure and chemical reactions within the chamber, a large diamond window suitable for spectroscopic sample analysis was implemented. The performance of the hybrid cell was validated from high-pressure neutron-diffraction measurements on carbon dioxide.
RESUMO
Cooling within gloveboxes is often restricted to expensive refrigerated bath circulators or small temperature differences. Here, we present a sturdy, inexpensive cooling system which matches various glovebox types and can be readily fabricated by a mechanical workshop in a few days. The system is suitable for cold plates of areas up to 150 cm2 and temperatures as low as -100 °C.
