摘要:

Metal layers one atom in thickness are the ultimate in ultrathin films. They are the object of intensive study. The preparation, characterization and properties of metal monolayers are reviewed. This field of research provides a sort of common meeting ground for clean-surface physics, chemisorption, and thin-film and surface metallurgy. The topics discussed include: the kinetics and thermodynamics of monolayer formation, monolayer structures and ‘two-dimensional’ phase transformations, desorption and binding energetics, electronic properties and chemical reactivity.

摘要:

The method of neutron diffraction on isotopically enriched samples is illustrated by reference to two types of liquid: molten salts and liquid semiconductors. It is shown that the method gives detailed and unique information about the structure of such liquids and allows theory and experiment to be compared at a microscopic level.

摘要:

Recent studies of the colour gauge theory of the strong interactions indicate that nuclear matter will transform into quark matter when heated or compressed by relatively modest amounts. Such matter almost certainly existed in the early Universe and is likely to be found in the interior of neutron stars. We investigate the possibility that it is formed in the collisions of relativistic heavy nuclei where it can be studied in a controlled and systematic way. As the primary cosmic ray beam provides us with heavy nuclei exceeding 106GeV primary energy, cosmic ray experiments can possibly provide us with a first glimpse of quark-gluon plasma, a state of matter that was the main contributor to the energy of the Universe up to 105s after the Big Bang.

摘要:

The article Newton'sPrinciple?(Speiser 1983) serves to propagate the view—long generally held but certainly erroneous—that thePrincipia(Cajori 1969) contains a proof that ‘all conic sections are solutions of [Newton's] universal law of gravitation’ (p. 149). It stops short, however, of expressing the more extreme commonly held misapprehension that thePrincipiagives—as it fallaciously purports to do—an outline of a proof that inverse-square force implies conic-section orbit; for the article goes on to say that only Johann Bernoulli succeeded in proving that the conic sections are the only solutions.
