Diffraction-based automated crystal centering
Journal of Synchrotron Radiation, 2007 A fully automated procedure for detecting and centering protein crystals in the X-ray beam of a macromolecular crystallography beamline has been developed. A cryo-loop centering routine that analyzes video images with an edge detection algorithm is first used to determine the dimensions of the loop holding the sample; then low-dose X-rays are used to ...

Crystallization of the Reaction Center of Photosystem II [PDF]
Acta Crystallographica Section A Foundations of Crystallography, 1996 The reaction center of Photosystem II (RCII) is the large multi-subunit membrane protein-pigment complex which the site of the primary photochemical reactions of oxygenic photosynthesis. These reactions include charge separation, sequential electron transfer and oxygen evolution (1,2).

Scientific problem of modifying of primary crystals a β -phase of silumin castings. Solutions
Литьë и металлургия, 2019 It is shown that the phosphorum which is contained in a silumin melt in number of 0,01–0,04% exists in the dissolved form. For a solution of the problem of modifying of primary crystals of a β -phase in silumin castings it is necessary to accept a ...

Nanostructural crystallization of metals
Литьë и металлургия, 2021 Based on thermodynamic calculations, it is shown that metal crystallization is an equilibrium nanostructural process. At the beginning, trigonal or tetragonal structure-forming nanocrystals are formed from elementary nanocrystals.
