Une technique de levitation de goutte sur film de gaz a ete utilisee pour effectuer des mesures de viscosite sans contact. La reponse dynamique d'une goutte a des perturbations est etudiee. Le modeles classiques traitant des oscillations libres amort

The gas levitation process development program has, so far, been focused mainly on contact-free manipulation, on molding and shaping of liquids, on high-temperature contact-free treatment, and on shaping and solidification of interesting materials fo

High-resolution studies of critical scattering indicate the presence of two different length scales in a variety of structural and magnetic phase transitions. In a previous work the anomalous scaling behavior of the narrow component in magnetic syste

A new, containerless method for measuring viscosity variations, as a function, e.g., of temperature or concentration, is described. Relative viscosities are extracted from the resonance quality factor near eigenfrequencies of deformation modes of gas

We suggest that the slow, scale-invariant coarsening regime in faceting kinetics is governed by long-tailed algebraic distributions of kink-antikink reorganization times. This makes the problem similar to dispersive charge transport in disordered mat

The use of synchrotron radiation in the study of ordering transitions is presented. The peak-profile measurements can be carried out with a resolution one order of magnitude better than with classical sources in all directions of the reciprocal latti

We consider transient behaviour in antiphase coarsening in simple binary alloys, and corrections to late-stage asymptotic scaling with an exponent of one half. (The problem might be of some importance to the metallurgical properties of composite micr

The stretched-exponential character of mechanical or dielectric relaxation in fragile glasses above T g, is considered from a dispersive-transport standpoint. Close to Tg we find the ‘stretching’ exponent β(T) to be proportional to (T—T o), wh

Under an applied horizontal temperature gradient, the free surface of a thin liquid layer gets tilted by a small angle proportional to the surface-tension temperature coefficient. The authors show the effect to be particularly large at the interface
