We investigate the phase behavior of surface-functionalized silica colloids at both the molecular and macroscopic levels. This investigation allows us to relate collective properties such as aggregation, gelation, and aging directly to molecular interfacia ...
The kinetics of condensation of D218O water vapor on D216O ice was studied in the temp. range 140-220 K. The measurements have been performed in real time using the pulsed valve technique in a low-pressure flow reactor. Ice samples were prepd. by several d ...
A low pressure reactor (Knudsen cell) coupled to molecular beam modulated mass spectrometry was used to study the heterogeneous kinetics of the following three systems: (1) NO2 on amorphous carbon, (2) H2O vapor on ice and (3) gaseous HCl on ice. The first ...
The combined stratification and melting of ice particles of ice slurries is theoretically described by multi-component fluid dynamics and the continuous-properties model (CPM) for melting and freezing, applied only to melting. Ice particle stratification w ...

The adsorption behaviour of Si(111)2 x 1 and Si(111)7 x 7 surfaces towards Fe(CO)5 has been investigated in the temperature range 80-300 K and in the exposure range 0.1-1000 L. For both surface reconstructions, the adsorption state is found to be molecular ...
The present work deals with two subjects. The interaction of NO2 and HONO with different types of soot are examined in the first part whereas in the second part an experimental set-up is presented which has been built in order to measure the kinetics of th ...
PLLA crystallization rates increase with nHA content owing to increased nucleation, which compensates a decrease in spherulite growth rate, G, at 100 to 130 °C, and to suppression of the twin peak in G(T) seen in pure PLLA, linked to a transition from the ...
In view of the uncertainty of the origin of the secular increase of N2O, we studied heterogeneous processes that contribute to formation of N2O in an environment that comes as close as possible to exhaust conditions contg. NO and SO2, among other constitue ...
