On June 2, 2017, the delegation of the Harbin Polytechnic University visited the RC OLMIV, accompanied by the director of the SPSU Research park Mikushev S.V.

Members of the delegation:

- Zhou Yu (rector of Harbin Polytechnic University)

- Zhao Hongzhui (Head of the Law Institute of Harbin Polytechnic University)

- Mei Wenzhang (head of the department for work with Russia and CIS countries).

In the conclusion of the meeting prof. Tunik S.P. spoke to the guests about the work of his scientific group.

The meeting was attended by Assoc.prof. Gracheva E.V. and Assoc.prof. Manshina A. A.

1,5-bis(R)-3,7-bis[2-(pyridine-2′-yl)ethyl)-1,5-diaza-3,7-diphosphacyclooctanes 1 and 2 and their copper(I) complexes 3 and 4 were developed. The butterfly-shaped copper-iodide core and unusual P,N-chelate and P,P-bridged coordination mode of the heterocyclic ligand in the dinuclear complexes 3 and 4 were revealed. Complexes 3 and 4 display emission in green range of spectra, with lifetimes in a microsecond domain and quantum yields of luminescence in solid-state up to 38 %. Thermochromic effects found for the phosphorescence of 4 in solutions are ascribed to rigidochromism.

«Correlated topographic and structural modification on Si surface during multi-shot femtosecond laser exposures: Si nanopolymorphs as potential local structural nanomarkers»

Applied Surface Science 416 (2017) 988–995

DOI: 10.1016/j.apsusc.2017.04.215

High-pressure Si-XII and Si-III nanocrystalline polymorphs, as well as amorphous Si phase, appear consequently during multi-shot femtosecond-laser exposure of crystalline Si wafer surface above its spallation threshold along with permanently developing quasi-regular surface texture (ripples, microcones), residual hydrostatic stresses and subsurface damage, which are characterized by scanning and transmission electron microscopy, as well as by Raman micro-spectroscopy. The consequent yields of these structural Si phases indicate not only their spatially different appearance, but also potentially enable to track nanoscale, transient laser-induced high-pressure, high-temperature physical processes – local variation of ablation mechanism and rate, pressurization/pressure release, melting/resolidification, amorphization, annealing – versus cumulative laser exposure and the related development of the surface topography.
