When heated rapidly, glasses often devitrify heterogeneously, i.e., by a softening front that originates at the surface of an amorphous film. Yet the fundamentals of this devitrification regime are not completely understood; depending on experimental

Surface-facilitated, front-propagated softening of glassy materials is now a well-known phenomenon, which is common to stable vapor deposited glasses. As we demonstrate in our recent communication, this softening pathway is not unique to vapor-deposi

Vapor deposition of molecules on a substrate often results in glassy materials of high kinetic stability and low enthalpy. The extraordinary properties of such glasses are attributed to high rates of surface diffusion during sample deposition, which

Faraday observed in 1850 "that a particle of water which could retain the liquid state whilst touching ice on only one side, could not retain the liquid if it were touched by ice on both" (M. Faraday, Royal Institution Discourse, June 7, 1850; Experi

The suggestion that a substrate whose architecture matches that of one of the faces of ice will make an effective nucleating agent goes back over 50 years. Over the years a number of experimental tests of this suggestion have been offered together wi

Interfacial melting of ice has been examined by infrared spectroscopy for the first time. Thin ice films, from 10 to 20 nm thick, were prepared on a face of a germanium prism and studied over a range of temperatures just below the triple point. Inter

Adsorption of H2O on the BaF2(111) surface was investigated at temperatures from −1 to 25 °C using infrared spectroscopy. At coverages near a monolayer, adsorbed films have spectra that are strikingly similar to those theoretically predicted for t

Melting dynamics of micrometer scale, polycrystalline samples of isobutane, dimethyl ether, methyl benzene, and 2-propanol were investigated by fast scanning calorimetry. When films are superheated with rates in excess of 105 K s−1, the melting pro

Temperature programmed desorption mass spectrometry (TPDMS) has been employed to study the interactions of hydrogen chloride with thin (200−1000 ML) ice films prepared under a variety of conditions. A single desorption state, designated as β-HCl,

High sensitivity temperature-programmed desorption mass spectrometry (TPDMS) was employed in order to investigate the desorption kinetics of CCl4 from thin (∼500 ML (ML: monolayer)) amorphous D2O ice films. TPDMS experiments demonstrate that at low
