The results of studies of supercooling upon crystallization value of Bi, Sn and Pb nanosized particles on the Al substrate and between the Al layers have been presented. It has been shown the efficiency of usage of layered film systems for investigation of the limiting supercooling in particle-matrix systems with an eutectic type of interaction between components. The obtained results have been discussed and compared with literature data. ----- Predstavleny rezultaty issledovanij pereohlazhdenij pri kristallizacii nanorazmernyh chastic Bi, Sn i Pb na Al podlozhke i mezhdu sloyami alyuminiya. Pokazana effektivnost ispolzovaniya sloistyh plenochnyh sistem dlya issledovaniya predelnogo pereohlazhdeniya v sistemah chastica-matrica s evtekticheskim tipom vzaimodejstviya mezhdu komponentami. Poluchennye rezultaty obsuzhdeny i sopostavleny s literaturnymi dannymi.
The results of studies of melting and crystallization processes in Bi-Ge layered film system are presented. These systems were prepared by subsequent condensation of components in vacuum. It has been shown that the melting temperature in system under
The decomposition and the reformation of the (Bi,Pb)2Sr2Ca2Cu3O10+d (?Bi,Pb(2223)?) phase have been investigated in-situ by means of High-Temperature Neutron Diffraction, both in sintered bulk samples and in Ag-sheathed monofilamentary tapes. Several
Two nanosized PrF3 samples were synthesized using two different procedures. The X-ray and HRTEM experiments showed high crystallinity of synthesized sample. Comparison of enhanced 141Pr NMR spectra of microsized (45 $mu$m) and nanosized PrF3 powder i
Higher order topological insulators (HOTIs) are a new class of topological materials which host protected states at the corners or hinges of a crystal. HOTIs provide an intriguing alternative platform for helical and chiral edge states and Majorana m
The magnetic behavior of $Fe_{3-x}O_4$ nanoparticles synthesized either by high-temperature decomposition of an organic iron precursor or low-temperature co-precipitation in aqueous conditions, is compared. Transmission electron microscopy, X-ray abs
