This paper discusses applications of vapor pressure to industrial hygiene. Vapor pressure is the quantitative term characterizing solvent volatility; it is also equivalent to the concentration of solvent vapor at the liquid surface. The ratio between this concentration at the source and the acceptable ...
Water vapor travels from areas of high pressure to low pressure seeking equilibrium. So underneath the concrete slab is a lot of moisture. Within the house is less moisture, so the interior of the building naturally draws moisture through the porous concrete. In a typical home, crawlspace barrie...
Recently, graphene has gained significant interest owing to its outstanding conductivity, mechanical strength, thermal stability, etc. Among various graphene synthesis methods, atmospheric pressure chemical vapor deposition (APCVD) is one of the best syn

That leaves a stabilized condensate that has a lower vapor pressure which is easier to handle, particularly when it must be shipped by truck or rail. The primary quality criterion for the vapor pressure of gas condensate is the RVP, which is a common measure of the volatility of condensate,...
Deposition rates range from less than 50 Å/min to several thousand Å/min and depend on many variables, including the nature of the target material (binding forces of the atoms), the atomic mass of the bombarding gas ions, the ion current, pressure of the gas, and the interelectrode ...

to fabricate nanoporous materials by utilizing the vapor pressure difference between constituent elements in an alloy to selectively remove a component with a high partial vapor pressure for 3DBO nanoporosity. We demonstrate that extensive elements, regardless of chemical activity, can be fabricated as ...
