Simulations of vapor water clusters at vapor–liquid equilibrium
The Journal of Chemical Physics, 2005The Gibbs-ensemble Monte Carlo methods based on the extended single point charge [H. J. C. Berendsen, J. R. Grigera, and T. P. Straatsma, J. Phys. Chem. 91, 6269 (1987)] potential-energy surface have been used to study the clustering of vapor phase water under vapor–liquid equilibrium conditions between 300 and 600K.

Adsorption Equilibria of Water Vapor on Cork
Journal of Agricultural and Food Chemistry, 2010We report here for the first time a complete thermodynamic study of water vapor adsorption on crude cork powder and plate. Adsorption-desorption isotherms were accurately measured by thermogravimetry at 283, 298, and 313 K in a large range of relative pressure. Adsorption enthalpies were determined by calorimetry as a function of loading.

Water vapor absorption in insects
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1983In common with other animals the principal examples of water transport in insects are to be found in processing food and in excretion. Some insects and other arthropods are able to absorb water vapor using preexisting buccal or rectal structures. This unique exploitation of atmospheric water depends on adequate areas for condensing water vapor and the

Ultrasonic Attenuation and Relaxation Times in Water Vapor and Heavy-Water Vapor
The Journal of the Acoustical Society of America, 1966Ultrasonic attenuation in water vapor and heavy-water vapor has been measured over the range of angular frequency/pressure from 10 to several hundred radian megacycles per second/atmosphere about 137°C. The resulting vibrational relaxation time at 1 atm for H2O vapor comes out to be about (8±2.5) × 10−9 sec and that in D2O vapor to be about (7.0±1.0) ×

The photolysis of water vapor has been studied in a flow system at rates up to 5 mole hr—1 and at temperatures up to 540°K under the influence of hydrogen discharge radiation around 1650 A. The products H2, O2 and H2O2 varied in amounts and proportions depending on the geometry of the system.

All building envelope assemblies accommodate flows of heat, air, and water. All building materials installed have an impact on water vapor flow, depending on their permeance or openness to water vapor flow. Water vapor control ensures that the permeances of the materials or components in an assembly do not lead to an unsafe accumulation of water within

Water vapor and sonoluminescence
The Journal of the Acoustical Society of America, 1999In recent work, it has been shown that segregation of gas mixtures within sonoluminescence bubbles is driven by strong thermal and pressure gradients inside the bubble [B. D. Storey and A. J. Szeri, ‘‘Mixture segregation within sonoluminescence bubbles,’’ in review].
