An international team measures the charge radius of the hydrogen nucleus and stumbles across some mysteries of physics Big problems sometimes come in small packages. The problem with which physicists must now concern themselves measures a mere 0.0350 millionth of a millionth of a millimeter. This is precisely the difference between the new, smaller, dimension of the proton, the nucleus of the hydrogen atom, and the value which has been assumed so far. Instead of 0.8768 femtometers it measures...

Rice physicists dig theoretical wells to mine quantum dots Graphane is the material of choice for physicists on the cutting edge of materials science, and Rice University researchers are right there with the pack "“ and perhaps a little ahead. Researchers mentored by Boris Yakobson, a Rice professor of mechanical engineering and materials science and of chemistry, have discovered the strategic extraction of hydrogen atoms from a two-dimensional sheet of graphane naturally opens up...

Rice experiment yields closest analog yet for classic atomic model Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved. The research is available online in Physical Review Letters. Bohr offered the first successful theoretical model of the atom in 1913, suggesting that electrons...

COLUMBUS, Ohio -- Chemists have calculated the structure of a very unusual molecule, one whose hyperactive atoms have earned it the nickname "the scrambler." This highly caustic "protonated methane," or CH5+, is also called a "super acid," and it is a short-lived player in the chemical reactions that make petroleum products. CH5+ should also be present in interstellar clouds where stars and planets form, said Anne B. McCoy, professor of chemistry at Ohio State University. McCoy hopes that...

Word of the Day
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
