ALUMINIUM BRONZE. NANOSTRUCTURAL PROCESSES OF MELTING AND MOULDING
Литьë и металлургия, 2018 It is shown that melting and molding of aluminum bronze are difficult physical and chemical processes. In them the major role is played by the centers of crystallization of dendrites of a a-phase, the a-phase nanocrystals dissolved and the adsorbed ...

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.

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).

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 ...

Interfacial Crystallization within Liquid Marbles
Condensed Matter, 2020 We report interfacial crystallization in the droplets of saline solutions placed on superhydrophobic surfaces and liquid marbles filled with the saline. Evaporation of saline droplets deposited on superhydrophobic surface resulted in the formation of cup-
