A study on the water vapor transport trend and water vapor source of the Tibetan Plateau
Theoretical and Applied Climatology, 2020The climatological characteristics of water vapor transport over the Tibetan Plateau (TP) were investigated in this study by using the ERA-interim and JRA55 monthly reanalysis dataset. The trends of water vapor budget and water vapor sources during the past 40 years were also revealed.

Water vapor and CO2 transport through amine-containing facilitated transport membranes
Reactive and Functional Polymers, 2015Abstract Amine-containing CO 2 facilitated transport membranes have great potential to be applied for hydrogen purification from synthesis gas. In some applications, the humidity of the retentate stream is required as well as the purity of hydrogen.

Transport properties of electrons in water vapor
Physical Review A, 1988Accurate values of transport properties of electrons in water vapor at room temperature are calculated, over a wide range of E/${n}_{0}$ values, from a numerical solution of Boltzmann's equation via the momentum method introduced earlier [Phys. Rev. A 33, 2068 (1986); 34, 2185 (1986)].

Water Vapor Transport Measurement across PEMs
ECS Transactions, 2014Water vapor transport through the PEM is one of the key parameters that can help achieve high performance and low-cost fuel cell system. Ex-situ water vapor transport rate (WVTR) measurement is extremely difficult and expensive to measure. This transport depends on many parameters such as ionomer equivalent weight, ionomer type, thickness ...

Mulch resistance to water vapor transport
Agricultural Water Management, 2011Abstract Mulches augment soil moisture availability to plants by restraining direct evaporation of soil water. Yet, in field conditions wind decreases their resistance to water vapor transport, diminishing their efficiency as a water conservation measure. The relation between vapor transport resistance and wind speed was investigated in a wind tunnel

Electron transport and ion clustering reactions in water vapor and deuterated water vapor
The Journal of Chemical Physics, 1975The interaction of low energy electrons and negative ions with pure water vapor and deuterated water vapor has been studied in the following two experiments: (I) A time-of-flight electron swarm experiment has been used to determine longitudinal electron diffusion coefficients, DL, in H2O and D2O for electric-field-to-pressure ratios, E/P, from 1 to 25 ...

Water vapor transport in structurally varied polyurethans
Journal of Macromolecular Science, Part B, 1969Abstract A study has been made on four chain-extended polyurethan (PU) elastomers differing only in the nature of the flexible segment, namely, poly(butylene adipate) (PBA), poly(tetramethvlene oxide) (PTMO), poly(propylene oxide) (PPO), and poly(ethylene oxide) (PEO).

Effect of temperature on water vapor transport properties
Journal of Building Physics, 2014The temperature effect on water vapor transport properties of calcium silicate is studied, together with the influence of sample thickness. For material characterization purposes, the bulk density, matrix density, and total open porosity are measured at first.

Water Vapor Transport in Hydrophilic Polyurethanes
1974Water uptake and water vapor transmission rates have been obtained on two series of hydrophilic segmented polyurethanes based on MDI, butanediol, and several block copolymer polyethers with varying proportions of poly(ethylene oxide) PEO and poly(propyleneoxide) PPO. In series I the ratio of PEO to PPO is varied at fixed hard segment concentration.
