Passivation of semiconductor surfaces against chemical attack can be achieved by terminating the surface-dangling bonds with a monovalent atom such as hydrogen. Such passivation invariably leads to ...
Astronomers have now observed the radio emission from the neutral hydrogen gas (HI) in a nearby galaxy. Hydrogen gas emits radio emission in a spectral line at a very specific frequency of 1420 MHz.
An international research team, led by Akitoshi Shiotari of the Fritz Haber Institute of the Max Planck Society (Germany), Mariana Rossi of the Max Planck Institute for the Structure and Dynamics of ...
THE experimental study of atomic spectra has a long and distinguished history. Even the descriptive analysis of spectra in terms of series and term values the systematic botany of spectra has a ...
A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR) in Pune, and the Raman Research Institute (RRI), in Bangalore, has used the Giant Metrewave Radio Telescope (GMRT) to ...
Astronomers from McGill University in Canada and the Indian Institute of Science (IISc) in Bengaluru have used data from the Giant Metrewave Radio Telescope (GMRT) in Pune to detect a radio signal ...
Atomic metallic hydrogen, if metastable at ambient pressure and temperature could be used as the most powerful chemical rocket fuel, as the atoms recombine to form molecular hydrogen. This ...
