THE quantum theory of line spectra developed by Bohr has been most successful in explaining the spectrum of hydrogen and helium, and by a further hypothesis the spectra of the alkali metals. By ...

WASHINGTON -- In a new study, investigators report an optimized approach to using laser-induced breakdown spectroscopy (LIBS) for analyzing hydrogen isotopes. Their new findings could enable improved ...

Although it is the smallest and lightest atom, hydrogen can have a big impact by infiltrating other materials and affecting ...

The discovery of isotopes in the early 20 th century marked a key moment in the history of physics and led to a much more refined understanding of the atomic nucleus. Isotopes are ‘versions’ of a ...

New results from tritium (H3) analysis of waters from the Langtang Valley, Nepal offer insight into the relative ages of different source waters in the glacierized catchment. Since tritium in the ...

One of the persistent mysteries about our Universe is the extreme imbalance between matter and antimatter. Antimatter and matter were both generated during the Big Bang, but the Universe is now ...

A team at the Colorado School of Mines is working to create hydrogen membranes for use in nuclear fusion power plants. The project, funded by the U.S. Department of Energy’s Advanced Research Projects ...

Deuterium is a stable isotope of hydrogen, which, unlike “normal” hydrogen atoms, or protium, also contains a neutron. The isotope deuterium has one proton, one neutron and one electron. One out of ...

Deuterium, a heavier but less abundant version of the hydrogen atom, has many practical applications. Unfortunately, producing deuterium and using it to protect silicon-based semiconductors requires a ...
