Structural stability during remelting of foundry binary alloys
A nanostructural mechanism of structural stability during remelting of foundry binary alloys has been developed. This mechanism is determined by the stability of the centers of crystallization of microcrystals of α‑phases and β‑phases.

PROBLEMS OF MODIFICATION STEEL CASTINGS BY NANOPARTICLES
It is suggested to use steel shot with the structure of tempered martensite for smelt modifying in the capacity of carriermodifier. It was applied barrier nickel layer and then wolfram nano-coating (over 200 nm) along with protective cobalt layer, which ...

NANOSTRUCTURAL PROCESSES OF MELTING, CRYSTALLIZATION AND MODIFYINGS OF METALS
It is shown that melting, crystallization and modifying of metals are difficult nanostructural processes. The nanocrystals and atoms of metals, the centers of crystallization of dendrites, surface-active elements, gases modifying elements, poorly soluble

Packing Hyperspheres in High-Dimensional Euclidean Spaces
We present the first study of disordered jammed hard-sphere packings in four-, five- and six-dimensional Euclidean spaces. Using a collision-driven packing generation algorithm, we obtain the first estimates for the packing fractions of the maximally ...

The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

HYPEREUTECTIC SILUMIN.NANOSTRUCTURAL PROCESSES OF MELTING AND MOULDING
It is shown that melting and molding of hypereutectic silumin are complicated physical and chemical nanostructural processes. The major part at these processes is played by the centers of crystallization of primary crystals of silicon, silicon ...

Моделирование сил взаимодействия частиц при упругопластическом расширении среды [PDF]
Изучено поле ускорений, возникающее в упругопластической гетерогенной среде Максвелла при её кристаллизации. Показано, что неоднородное расширение этой среды приводит к взаимному притяжению частиц (центров кристаллизации) и возникновению силового поля ...

From liquid to solid bonding in cohesive granular media
We study the transition of a granular packing from liquid to solid bonding in the course of drying. The particles are initially wetted by a liquid brine and the cohesion of the packing is ensured by capillary forces, but the crystallization of the solute

This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.
