high-vacuum thermal insulation
41Solar air conditioning — refers to any air conditioning (cooling) system that uses solar power. This can be done through passive solar, photovoltaic conversion (sun to electricity), or solar thermal energy conversion. The U.S. Energy Independence and Security Act of… …
42Cryogenic storage dewar — A self pressurising dewar (silver, foreground) being filled with liquid nitrogen from a large storage tank (white, background). Cryogenic storage dewars are specialised types of vacuum flask used for storing cryogens (such as liquid nitrogen or… …
43Borosilicate glass — is a type of glass with the main glass forming constituents silica and boron oxide. Borosilicate glasses are most well known for having very low coefficient of thermal expansion ( 5 / 0 6 / C at 20oC), making them resistant to thermal shock, more …
44Insulated shipping container — Insulated shipping containers are a type of packaging used to ship temperature sensitive products such as foods, pharmaceuticals, and chemicals. They are used as part of a cold chain to help maintain product freshness and efficacy.ConstructionAn… …
45Epoxy — In chemistry, epoxy or polyepoxide is a thermosetting epoxide polymer that cures (polymerizes and crosslinks) when mixed with a catalyzing agent or hardener . Most common epoxy resins are produced from a reaction between epichlorohydrin and… …

47Superconducting magnetic energy storage — (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature. A typical SMES system includes… …
48Allotropes of carbon — Eight allotropes of carbon: a) Diamond, b) Graphite, c) Lonsdaleite, d) C60 (Buckminsterfullerene or buckyball), e) C540, f) C70, g) Amorphous carbon, and h) single walled carbon nanotube or buckytube. This is a list of the allotropes of carb …
49Direct-EI LC-MS interface — is a simple coupling technique between liquid chromatography and mass spectrometry (LC MS) developed by Achille Cappiello and coworkers.[1] It is based on the direct and efficient introduction of a liquid effluent into an electron ionization (EI) …
50Wood drying — (also seasoning lumber or timber seasoning) refers to reducing the moisture content of wood prior to its use. For some purposes wood is not dried at all (it is used green ) [http://en.wikipedia.org/wiki/Green wood] . Often the wood needs to be in …
