The Physics of Molecular Motors
Accounts of Chemical Research, 2001Molecular motors convert chemical energy into mechanical force and movement. Operating at energies just above those of the thermal bath, these motors experience large fluctuations, and their physical description must be necessarily stochastic. Here, motor operation is described as a biased diffusion on a potential energy surface defined by the ...

In the hyperpolarisation method known as dynamic nuclear polarisation (DNP), a small amount of unpaired electron spins is added to the sample containing the nuclear spins and the polarisation of these unpaired electron spins is transferred to the nuclear spins by means of a microwave field.

Abstract Clausius was careful to add that Hirn, his long-standing opponent who had never accepted the kinetic theory, meant m to be the ‘sum of the atomic volumes’ and l to be the ‘sum of the internal actions’ or an ‘internal pressure’.

The Chemistry and Physics of Molecular Surfaces
Zeitschrift für Physik D Atoms, Molecules and Clusters, 1986This article reviews the results of several recent experiments performed in our laboratory designed to elucidate the fundamental chemical and physical properties of clusters of both transition metals and other refractory elements containing from one to several hundred atoms. The gas-phase reactivity of clusters towards a variety of reagents is explored

Optical spectroscopy has proved to be an invaluable tool for probing atomic and molecular systems. The historical role of atomic spectroscopy in revealing quantum effects and validating quantum theory is well-documented, from the first interpretation of the Balmer series in hydrogen to the measurement of the Lamb shift in hydrogen, spectroscopy was the

Physics and the origins of molecular biology
Journal of Genetics, 2006Bohr, Delbrück and Schrödinger were physicists who had important influences on biology in the second half of the twentieth century. They thought that future studies of the gene might reveal new principles or paradoxes, analogous to the wave/particle paradox of light propagation, or even new physical laws. This stimulated several physicists to enter the
