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 ...

Dipole-Center in ZnSe Crystals

Ukrainian Journal of Physics, 2022
It has been found that the well-known luminescence band with a maximum near 630 nm in undoped ZnSe crystals is associated with the recombination of free electrons at localized holes and free holes at localized electrons. The result was achieved by comparing experimental values for the stationary luminescence intensity with the phosphorescence and ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

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-

White Dwarfs In Ngc6397 And M4: Constraints On The Physics Of Crystallization [PDF]

, 2010
We explore the physics of crystallization in the dense Coulomb plasma of the deep interiors of white dwarf stars using the color-magnitude diagram and luminosity function constructed from Hubble Space Telescope photometry of the globular cluster M 4 and ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Structural heredity in the casting of eutectic cast iron

Литьë и металлургия
It has been shown that the effect of structural inheritance in casting eutectic cast irons can be explained from the standpoint of nanostructured crystallization of foundry alloys. Proposed is a mechanism of structural heredity when casting eutectic cast
