Density waves theory of the capsid structure of small icosahedral viruses

open access: yes, 2006
We apply Landau theory of crystallization to explain and to classify the capsid structures of small viruses with spherical topology and icosahedral symmetry.

Scientific problem of modifying of primary crystals a -phase of silumin castings. Solutions

open access: yesЛитьë и металлургия, 2019
It is shown that intermetallic metals of the modifying ligatures are not the crystallization centers of primary crystals of a a-phase. As the main demodifier serves hydrogen dissolved in liquid silumin.

History dependent crystallization of Zr41Ti14Cu12Ni10Be23 melts [PDF]

open access: yes, 2000
The crystallization of Zr41Ti14Cu12Ni10Be23 (Vit 1) melts during constant heating is investigated. (Vit 1) melts are cooled with different rates into the amorphous state and the crystallization temperature upon subsequent heating is studied. In addition,

EXPERIMENTAL DETERMINATION OF THE RATES OF NUCLEATION AND OF GROWTH OF PHASE TRANSFORMATION CENTERS

open access: yesТонкие химические технологии, 2016
The processes of granulation by crystallization of molten droplets in the flow of a cooling agent (prilling) and on the cooled surfaces of the granulators are widely used in the chemical and allied industries. The process of granulation (crystallization)

Experimental and Theoretical Study of Kinetics of Bulk Crystallization in Poly(Chlorotrifluoroethylene)

open access: yesJournal of Research of the National Bureau of Standards Section A Physics and Chemistry, 1959
The rate of isothermal bulk crystallization of poly(chlorotrifluoroethylene), Tm=221° C, was measured from 170° to 200° C. The intrinsic bulk crystallization, which accurately followed an n = 2 law, was shown to be a result of the injection of primary ...

Nanostructural theory of metal melts. Foundry production and metallurgy

open access: yesЛитьë и металлургия, 2020
It has been shown that atomic and atomic cluster theories cannot be the basis for theories of crystallization and modification of metals and alloys. Based on thermodynamic calculations, a nanostructural theory of metal melts has been developed.

fDETECT webserver: fast predictor of propensity for protein production, purification, and crystallization [PDF]

open access: yes, 2017
Background: Development of predictors of propensity of protein sequences for successful crystallization has been actively pursued for over a decade. A few novel methods that expanded the scope of these predictions to address additional steps of protein ...

The structural organization and protein composition of lens fiber junctions. [PDF]

open access: yes, 1989
The structural organization and protein composition of lens fiber junctions isolated from adult bovine and calf lenses were studied using combined electron microscopy, immunolocalization with monoclonal and polyclonal anti-MIP and anti-MP70 (two putative
