Latest Nucleation Stories
Perfect sheets of diamond a few atoms thick appear to be possible even without the big squeeze that makes natural gems.
This classical theory of crystal formation, which occurs widely in nature and in the chemical industry, was under fire for some years, but is saved now.
Peritectic solidification involves the nucleation and growth of the primary phase, the peritectic reaction of the primary phase with the remnant liquid phase, and the microstructural evolution of the product peritectic phase.
Earth's climate is strongly influenced by the presence of particles of different shapes and origins -- in the form of dust, ice and pollutants -- that find their way into the lowest portion of the atmosphere, the troposphere.
Haze, scientifically known as atmospheric aerosols - microscopic particles suspended in the Earth's atmosphere - represents a major environmental problem because it degrades visibility, affects human health and influences the climate.
Engineers at the University of Leeds have developed a simple technology which can be used in existing chemical reactors to ensure "right first time" drug crystal formation.
SAN JOSE, Calif., Nov.
SAN JOSE, Calif., April 16 /PRNewswire-FirstCall/ -- As semiconductor devices scale to the 32nm technology node and beyond, shrinking contact and via dimensions make chemical vapor deposition (CVD) of tungsten more challenging.
By Phillion, A B Lee, P D; Maire, E; Cockcroft, S L Semisolid tensile testing combined with X-ray microtomography (XMT) was used to characterize the development of internal damage as a function of strain in an aluminum-magnesium alloy, AA5182.
