Rev Chem Eng 27 (2011): 1–13 © 2011 by Walter de Gruyter • Berlin • Boston. DOI 10.1515/REVCE.2011.003 Nucleation of protein condensed phases Peter G. Vekilov Department of Chemical and Biomolecular Engineering and Department of Chemistry , University of Houston, Houston, TX 77204-4004 , USA , e-mail: Abstract Proteins in solution form a number of condensed phases. Even omitting the amyloid structures formed after partial protein unfolding, these phases include crystals, polymers, and other solid aggregates, as well as dense

Greek orally for a while. Each of these difficulties can be explained by a single technical statement: None of the scholars concerned in each of the difficulties mentioned above had achieved lan- guage nucleation. NUCLEATTON IN PHYSICS When a droplet is condensed out of a gas, or when a crystalline solid is precipitated out of a liquid, NUCLEATION1 has occurred. Nucleation is involved in the first small clustering of atoms or molecules — say the first two or three dozen — into a structural pattern which will then be extensively duplicated in a repetitive

Baumgärtel* The Impact of Non-Electrolyte Impurities on the Nucleation Rate of Ice Ih Abstract: The nucleation rates of binary mixtures of water with dioxane, glycole, ethanol, 𝑖-propanol and urea have been investigated. Already at very low molar fraction (𝑥 = 0.002) of the additives a considerable decrease of the nucleation rates has been observed. With increasing concentration of dioxane (𝑥 = 0.04 − 0.477) a strong decrease of the nucleation temperature related to the

temperature and cooling rate are controlled. There are, however, limits to laboratory investigations. For one, it is not yet possible to observe the onset of crystallization because nucleation clusters consist of only tens to thousands of atoms ( Lasaga 1998 ). It is also difficult to measure the kinetics of crystallization in highly viscous melts because of the long run times needed to achieve visible crystals (e.g., Schairer and Bowen 1956 ; Johannes 1979 ). Experiments on crystal nucleation in viscous melts are also few because of their significant incubation periods

Guilin Sun, Bo Song*, Sufen Tao and Zeyun Cai Effect of Manganese Sulphide Size on the Precipitation of Tin Heterogeneous Nucleation in as-Cast Steel Abstract: Tramp elements in steels such as tin have been thought harmful because of the hot brittleness at grain boundaries and will be enriched in new steels because of difficulty of removal. It has been an important and diffi- cult matter for metallurgist to use these elements. In the present paper, the as-cast steel containing high concen- tration of tin is prepared in laboratory and tin precipitates at
