In this chapter we formulate an ice active surface site based stochastic model of heterogeneous freezing with the unique feature of invoking a continuum assumption on the ice nucleating activity (contact angle) of an aerosol particle’s surface, that requires no assumptions about the size or number of active sites. The result is a particle specific property g that defines a distribution of local...

Magnesium chloride hexahydrate and magnesium nitrate were tested for their thermal energy storage in a mixture with carbon materials. The graphite, graphene zeolite-templated replicas used as nucleating agent to supress supercooling. addition of any type into did not lead decrease the supercooling significant enthalpy fusion crystallisation was observed. mixtures after cycling apparently wet, i...

Among glass-ceramics, MgO-Al2O3-SiO2 (MAS) system occupies an important place due to its good characteristics. In this study, the magnesite waste being industrial was evaluated for production of MAS glass ceramics and properties glass-ceramics produced were examined. For purpose, mixtures prepared using waste, quartz, kaolin alumina raw materials according chemical composition cordierite. Furth...

Microtubules (MTs) in the axon have a uniform polarity orientation that is recapitulated during recovery from episodes of MT depolymerization (Heidemann, S. R., M. A. Hamborg, S. J. Thomas, B. Song, S. Lindley, and D. Chu. 1984. J. Cell Biol. 99:1289-1295). This tight regulation of their organization indicates that axonal MTs are spatially regulated by discrete nucleating structures comparable ...

Biliary calcium may be a nucleating agent in cholesterol cholelithiasis. A study was designed to determine the effect of binding of ionised calcium on in vitro nucleation time. Ultracentrifuged and microscopically clear gall bladder bile from cholesterol gall stone patients was divided into two aliquots. One aliquot served as control and ionised calcium was bound in the second aliquot by additi...

A polyethylene film with an incorporated nanodispersed polyaniline conductive network was developed by controlled crazing in a high-pressure reactor while immersed emulsified medium of aniline chloroform. The resulting material exhibited average through-plane electron conductivity 2 × 10–2 S·cm–1, within order magnitude brittle doped (1.2 10–1 S·cm–1), yet retained the ductility matrix. It also...
