Theories, hypotheses of hydrothermal rockhorehformation and reality: facts and arguments

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevance of the research is caused by the necessity to introduce the clarity into hydrothermal rock-, ore-formation theories and hypotheses in which some natural facts are not joined.

Determination of the Surface Plasmons Polaritons extraction efficiency from a self-assembled plasmonic crystal [PDF]

open access: yesarXiv, 2013
We experimentally measure and analytically describe the fluorescence enhancement obtained by depositing CdSe/CdS nanocrystals onto a gold plasmonic crystal, a two-dimensional grating of macroscopic size obtained by gold deposition on a self-assembled opal.

Percolation threshold gold films on columnar coatings: characterisation for SERS applications [PDF]

open access: yesarXiv, 2016
Percolation of gold films of ~15 nm thickness was controlled to achieve the largest openings during Au deposition. Gold was evaporated on 300-nm-thick films of nanostructured porous and columnar SiO2, TiO2 and MgF2 which were deposited by controlling the angle, rotation speed during film formation and ambient pressure.
