Such materials were then said to be hygroscopic because they were suitable for making a hygroscope. Eventually, the word hygroscope ceased to be used for any such instrument in modern usage, but the word hygroscopic (tending to retain moisture) lived on, and thus also hygroscopy (the ability to do so).
Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components lignin , cellulose and hemicellulose which decreases its hygroscopy and thus increases dimensional ...
Equilibrium moisture content of wood versus humidity and temperature, according to the Hailwood-Horrobin equation. The equilibrium moisture content (EMC) of a hygroscopic material surrounded at least partially by air is the moisture content at which the material is neither gaining nor losing moisture.
The Hygroscopic Cycle is a concept that has evolved recently and is at the heart of intensive research on hygroscopic fluids. Recent developments have been the Kalina cycle , [ 17 ] but with the actual configuration, it is expected to have an impact in locations with poor access to water, and a good integration with combined cycle plants, and ...
The wood is dense and very hard, difficult to plane, but drills, sands and turns well. It is termite resistant. It was once used for railway sleepers and is now prized for ornamental work and furniture. It burns very slowly with intense heat, and is often used for a fire which is intended to burn all night in order to keep wild animals at bay.
