Comparative Evaluation of HFC‐134a Decompositions Over Metal‐Impregnated γ‐Al2O3 Catalysts (M/γ‐Al2O3) (M = Mg, Ni, Co, Zn, Cu)

Advanced Energy & Sustainability Research
Al2O3, widely used in the catalytic decomposition of fluorocarbons, is known to be rapidly deactivated owing to its transformation to AlF3. Accordingly, in this study, metal‐impregnated γ‐Al2O3 catalysts (M/γ‐Al2O3) were synthesized and their long‐term ...

A Combine On-Line Acoustic Flowmeter and Fluorocarbon Coolant Mixture Analyzer for The ATLAS Silicon Tracker

, 2012
An upgrade to the ATLAS silicon tracker cooling control system may require a change from C3F8 (octafluoro-propane) to a blend containing 10-30% of C2F6 (hexafluoro-ethane) to reduce the evaporation temperature and better protect the silicon from ...

Overcoming tumor hypoxia as a barrier to radiotherapy, chemotherapy and immunotherapy in cancer treatment

International Journal of Nanomedicine, 2018
Kaitlin Graham, Evan Unger NuvOx Pharma, Tucson, AZ, USA Abstract: Hypoxia exists to some degree in most solid tumors due to inadequate oxygen delivery of the abnormal vasculature which cannot meet the demands of the rapidly proliferating cancer cells.
