Since its invention by Dr. John T. Gleaves (then at Monsanto Company) in late 1980s, [1] TAP has been used to study a variety of industrially and academically relevant catalytic reactions, bridging the gap between surface science experiments and applied catalysis. [2] The state-of-the-art TAP installations (TAP-3) do not only provide better ...
It was announced in May 2022 that a sequel to This Is Spinal Tap was in development, with Rob Reiner, Christopher Guest, Michael McKean and Harry Shearer reprising their roles and Reiner returning as director. [2] In November 2023, Reiner announced musicians Paul McCartney, Elton John and Garth Brooks were set to make cameo appearances as ...
Tungsten disilicide is a replacement for earlier tungsten films. [2] Tungsten disilicide is also used as a barrier layer between silicon and other metals, e.g. tungsten. Tungsten disilicide is also of value towards use in microelectromechanical systems , where it is mostly applied as thin films for fabrication of microscale circuits.
A woman who underwent a trial immunotherapy as a child for neuroblastoma — an aggressive nerve tissue tumor that occurs often in children under 5 — has since been in remission for 18 years ...
David Blaine is a daredevil at heart. In PEOPLE's exclusive sneak peek of National Geographic's latest series, David Blaine Do Not Attempt, the famed magician, 51, pushes the boundaries of what ...
Here are some of the energy-related executive orders Trump could announce during his first days in office, as he seeks to follow through on that promise. Trump could order the U.S. to withdraw ...
The first crystalline silicic acid was prepared from the phyllosilicate natrosilite (Na 2 Si 2 O 5) in 1924. More than 15 crystalline acids are known and comprise at least six modifications of H 2 Si 2 O 5. Some acids can adsorb and intercalate organic molecules, and therefore are interesting alternatives to silica. [10]
The exact mechanism of transport is not known; however, findings indicate that ATP binding to TAP-1 is the initial step in the transport process, and that ATP bound to TAP-1 induces ATP binding in TAP-2. It has also been shown that undocking of the loaded MHC class I is linked to the transport cycle of TAP caused by signals from the TAP-1 subunit.
