Vapor phase clustering model for water
… nucleation of liquid droplets from water vapor. Homogeneous nucleation involves only molecules of a single substance and does not include the complicating effects due to a substrate or piece of foreign matter. The semiphenomenological liquid drop theories developed nearly three decades ago …

An experimental investigation of fuel spray vapor phase characterization
… laser extinction technique for measuring fuel vapor flux in evaporating liquid fuel sprays was conducted. The infrared laser extinction technique consists of three separate measurements: a visible light angular scattering measurement, a visible light line-of-sight extinction measurement and an …

Organic lateral heterojunction devices for vapor-phase chemical detection
… sensors have demonstrated effective ultra-trace, vapor-phase detection of trinitrotoluene (TNT) at security checkpoints and during vehicular sweeps, achieving sensitivity levels comparable to the canine nose. In this sensor scheme, a large contribution to the noise signal is the inefficient …

Multiscale models of the metalorganic vapor phase epitaxy process
… thesis develops modeling techniques for chemical vapor deposition processes, specifically metalorganic vapor phase epitaxy (MOVPE). The difficulty in creating an overall modeling strategy for the MOVPE process is that important processes occur on a wide range of length and time scales. Gas phase …

Studies of the vapor phase photodissociation of azomethane-d(6)
The photodissociation of fully deuterated azomethane into two CD$\sb3$ radicals and N$\sb2$ was studied using transient CARS spectroscopy as a nanosecond resolved probe of the photoproducts. The Raman-active $\nu\sb1$ symmetric C-D stretching band of CD$\sb3$ radicals was observed and the following …

Liquid-vapor phase change phenomena for heat exchangers and electronics cooling
Phase change heat transfer is an attractive heat transfer process due to its superior heat transfer coefficients as compared to single phase heat transfer. Among the fluids used as refrigerants, water is of interest for its good thermodynamic properties. It is in addition widely available, …

INVESTIGATION OF PROCESSING-STRUCTURE-PROPERTY RELATIONS IN VAPOR PHASE MODIFIED CELLULOSIC MATERIALS
… is either surface modification or regeneration. Vapor phase modification of cellulose has gained interest in recent years. Instead of using liquid phase precursor solutions, vapor phase processing uses gas molecules as precursors to realize surface coatings with better uniformity and consistency …
