The most serious accident tliat Ciui occur in a nuclear plant is a reactor core meltdown. In a core meltdown, the enclosed gases physically melt through tlie reactor vessel, and once contacting with cooler liquids or vapors either in a cooling jacket or in the outer enviromnent, cause a physical e. plosion to occur. However, tlie hazard caused by the e. plosion itself is minimal and more localized compared with the release of radioactive material that accompanies such an accident. [Pg.231]

Myrtaceae used in Australian traditional medicine), exists in a keto-enol tautomer ratio of 3 2. This compound was known previously as a synthetic product but only limited physical (melting point) and no spectroscopic data were available. The (3-hydroxychalcone constituent obtained from Millettia leucantha (26) is a further example of a retrochalcone. ... [Pg.1019]

Physically, melting point implies the coexistence of the solid and the liquid phase. Microscopically, the situation can be represented by considering the coexistence of... [Pg.50]

However, the melting or plasticating process that follows the solids conveying zone is a relatively complex one, and unlike the melt extrusion and solids conveying processes, the detailed physical melting mechanisms cannot be easily visualized, predicated, and modeled from basic principles without experimental investigation. [Pg.474]

From Metal Halides, Phosphine and Halogen Acceptors. This method was set up by Kruck and co-workers to isolate nickel (0) 118) palladium (0), and platinum (0) 117) tetrakisfluorophosphine derivatives. The halogen acceptor was copper, and the reaction conditions were rather mild for nickel (100° C., 135 atm.) and more drastic for palladium and platinum (100° C., 350 atm.). The physical (melting and boiling points) and chemical (decomposition, temperature) properties of these compounds are reported below ... [Pg.326]

Solution concentration is defined as the amount of solute dissolved in a given amount of solution. The concentration of a solution has a profound effect on the properties of a solution, both physical (melting and boiling points) and chemical (solution reactivity). Solution concentration may be expressed in many different units. Here we consider concentration units based on percentage. [Pg.181]

Plastic/mbber blends offer a way to combine the best of both worlds - the softness and elasticity of rubber and the processability of thermoplastic. As discussed in this chapter, there are several methods for the preparation of plastic/mbber blends. Physical melt mixing of the plastics and mbbers provides a simple, quick, and most economical way of producing such blends. One can also prepare multicomponent and specialty blends by this procedure. Both Banbury batch mixers and twin-screw mixers are used to produce these blends. Most physical blends are now prepared by this melt-mbdng process. [Pg.158]

It is possible to chemically string chains of different polymers together (forming block copolymers or through randomised copolymerisation) or physically melt different polymers into a blend to gain beneficial synergised properties. These altered properties are also determined by the above two factors, ie, intra- and inter-polymer molecular interactions. These are the fundamental characteristics of polymer interactions at molecular scales. [Pg.6]
