The company, which was not the sole source of the pollution but is the only business working on the cleanup, has already spent several million dollars installing ventilation systems and creating a network of wells, pumps and filters to extract chemical contaminants from groundwater. The vapor prob...
A water vapor outlet valve receives water vapor from the upper chamber. The barrier has a plurality of openings for water vapor to pass from the lower chamber to the upper chamber and allows condensed water to pass from the upper chamber to the lower chamber. The steam generator includes a ...
Chemical vapor deposition (CVD) is a deposition process of solid materials at a high temperature as a result of a chemical reaction directly over the substrate. In other words, CVD is a generic name for a group of processes whereby a thin solid film is deposited onto a substrate through che...
Novel mathematical models for flavour release during drinking are described, based on the physiology of breathing and swallowing. Surprisingly, we conclude... Valéry,Normand,Shane,... - 《Chemical Senses》 被引量: 45发表: 2004年 Immediate effects of breath holding maneuvers onto composition of exh...
(MOCVD), depending on the precursor phase used. As the name suggests, AACVD uses liquid/gas aerosol to transport the precursor. In DLICVD, the precursor is transported/injected into the chamber in the liquid phase directly. In MOCVD, metal organic precursors are used, which helps in the ...
Creating a chemical object involves identifying the appropriate chemical by name through a database, and retrieving all constant and temperature and pressure dependent coefficients from Pandas DataFrames - a ~1 ms process. To obtain properties at different conditions quickly, the method calculate has ...

Water vapor is one of the most important species in the middle atmosphere. It plays many roles in chemical and radiative processes. However, measurements of stratospheric and mesospheric water vapor are very sparse in time and in space. This makes it difficult to estimate long-term changes, ...
When the biomass is heated up to 500° C, it produces water vapor and volatile compounds from the polysaccharides (for example, starch, cellulose, and hemicellulose), lignin, proteins, lipids, fat, and pectin. The disintegrated components react in the second stage (500–600 °C) to form ...
The low pressure chemical vapor deposition (LPCVD) of copper from its bis‐hexafluoroacetylacetonate is studied on oxidized silicon substrates partially covered with a platinum seeding layer. With a known concentration of water vapor in the gas mixture, almost equal copper film growth rates are obtain...
