Nuclear detectors for x-ray and gamma-ray spectroscopy imaging are a vital tool in many homeland security, medical imaging, astrophysics other applications. Most of these applications require room-temperature operation due to the operational constraints imposed by cryogenic cooling system. CdZnTe (CZT) has been main material with desired detection properties, CZT crystals have used commercially...

Water-cooling plays a major role in extracting heat from both the mold and solidifying metal during the continuous casting of steel and aluminum alloys and is characterized by complex boiling phenomena. Heat extraction rates during water-cooling, which have strong dependence on the metal surface temperature, can rapidly change with time as the strand cools down. Consequently, uncontrolled cooli...

A titanium–iron intermetallic with minor addition of manganese (TiFe0.7Mn0.3) was processed by severe plastic deformation through high-pressure sliding (HPS). rectangular strip sample embedded in stainless steel and strained under a pressure 4 GPa at room temperature. The hydrogen storage kinetics activation the HPS-processed were significantly enhanced comparison as-received ingot without HPS ...
