AbstractThe modern concepts of the structure of liquid metals and alloys are considered. Several types of microinhomogeneity and microheterogeneity are shown to exist in liquid metal solutions. Their structural state changes as a result of variations in composition, history, temperature, and pressure or the influence of various external actions. Up...

Abstract—The article discusses a set of scientific and applied problems about the meaning and bases, content, and consequences of structural transformations of the municipal space. Interest in these problems is caused by the need to search for reasons for the increased variability of the structural organization of this space, which throughout the p...

AbstractHole production in high-strength steels (in particular, manganese steels) by plasma incision and reaming is considered. Thermal conditions are identified for preliminary plasma incision of holes with subsequent reaming. Phase and structural transformations in the surface layer after plasma treatment greatly improve the efficiency of subsequ...

AbstractSamples of Fe–B alloys have been prepared by quenching a melt using a rotating copper disk and then were certified by XRD analysis. Some of the alloys were found to possess an amorphous structure. Fe–B amorphous ribbons exhibit a sequence of gyromagnetic effects that replace each other as the temperature of the sample changes. These feature...

An abrupt change in the electrophysical properties of aqueous colloidal nanodiamond solutions, which is associated with a change in the spatial structure of nanodiamond-based aqueous nanoassociates, is shown. The freezing point depression and the hysteresis of conductivity and dielectric permeability are determined. The zone crystallization of a de...

A Ti9O10 nanophase (sp. gr. Immm) has been synthesized via high-energy milling followed by prolonged high-temperature vacuum heat treatment of nonstoichiometric TiOy titanium monoxide. The atomic structure and microstructure of Ti9O10 have been investigated by X-ray powder diffraction and high-resolution transmission electron microscopy. According ...

The self-assembly of eight PdII cations and sixteen phenanthrene-derived bridging ligands with 60° bite angles yielded a novel M8 L16 metallosupramolecular architecture composed of two interlocked D4h -symmetric barrel-shaped containers. Mass spectrometry, NMR spectroscopy, and X-ray analysis revealed this self-assembled structure to be a very larg...

A discrete complex [Zn(tpro)2(H2O)2] ( 1 , Htpro = l -thioproline), and two structural isomers of coordination polymers, a 1D chain of [Zn(tpro)2]n ( 2 ) and a layered structure [Zn(tpro)2]n ( 3 ), were synthesized and characterized. The discrete complex 1 undergoes a temperature-driven structural transformation, leading to the formation of a 1D he...
