Открыто спонтанное образование в течение 4 ч скин-слоя дистиллированной воды толщиной до 3 мм при комнатной температуре с новыми свойствами. Обнаружены деформация ОН-полосы комбинационного рассеяния вкладом компоненты льда ( 3200 см-1), снижение коэффициента упругого рассеяния и его флуктуаций, а также увеличение на 20 капиллярах. Восстановление слоя после обогащения воздухом в результате перемешивания указывает на стабильность ...

Rhombohedral CoTiO3 is a Dirac-type antiferromagnet with unique nodal magnetic dynamics, a strong Zeeman-phonon effect, and multiple spin-orbital excitations. The intricate interaction between these excitations makes it difficult to precisely understand its properties. We report the observation of strong spin-phonon coupling for several phonon modes, as well as the Zeeman splitting of the degenerate phonon modes with 𝐸𝑔 symmetry. ...

A new generation of nanodiamonds produced from hydrocarbons at high pressure has recently expanded the family of bottom-up-synthesis nanodiamonds. The first steps towards characterization of this nanomaterial allow us to suppose that more than one of its remarkable properties and applications will be demonstrated in the coming years. Here we report the Raman features of ultrasmall (2–5 nm) ...

Modification of optical phonon spectra in contacting nonpolar nanoparticles compared to single particles is studied. Optical phonons in dielectric and semiconducting particles obey the Euclidean metric Klein-Fock-Gordon equation with Dirichlet boundary conditions. This equation is supposed to be solved numerically for manifolds of cojoined spheres. It is proposed to replace this problem with the simpler-to-solve ...

Crystallization of a Na 2 O-K 2 O-Nb 2 O 5 -SiO 2 glass under thermal poling and subsequent annealing was studied by Raman spectroscopy and X-ray diffractometry. It was found that the poling and subsequent thermal treatment lead to partial crystallization of the poled region of the glass, which should be related with watering ...

Recent Raman data on nanocrystallite arrays are revised within the microscopic
theory for Raman peaks positions and broadening (linewidth). The theory
combines the elasticity theory-like approach for optical phonons used in
order to evaluate the Raman peaks structure and the Green's function method
applied for the phonon lines broadening. These theories are supported by the
atomistic calculations within the dynamical ...

We report the evolution of charge density wave states under pressure for two NbS3 phases: triclinic (phase I) and monoclinic (phase II) at room temperature. Raman and x-ray diffraction (XRD) techniques are applied. The x-ray studies on the monoclinic phase under pressure show a compression of the lattice at different rates below and above ∼7 GPa but ...

Electron–phonon interaction strongly affects and often limits charge transport in organic semiconductors (OSs). However, approaches to its experimental probing are still in their infancy. In this study, we probe the local electron–phonon interaction (quantified by the charge-transfer reorganization energy) in small-molecule OSs by means of Raman spectroscopy. Applying density functional theory calculations to four series ...

The statistics of hot spots in the ensemble of self-assembled silver nanoislands grown
on the surface of silver-to-sodium ion exchanged glass under hydrogen annealing was studied.
The comparison of the surface enhanced Raman scattering (SERS) performance of the nanoisland
films at different growth stages with the developed model of the hot spots formation revealed that
at the nanoislands coalescence ...

Исследована модификация графенового листа, полученного методом химического газофазного осаждения на медной мелкоячеистой сетке, под действием мощного фемтосекундного лазерного излучения. Установлено, что процесс длительного облучения образца в вакууме сопровождается 1) разрывом углеродных связей, о чем свидетельствует уменьшение яркости рефлексов, отвечающих дифракции электронного пучка на графене, и 2) образованием новых продуктов, о чем свидетельствуют появление новых дифракционных ...

Materials, consisting of Jahn-Teller (JT) ions, such as cuprates and manganites, display many outstanding properties, including high temperature superconductivity and colossal magnetoresistance. There, the role of JT effect, although widely recognized, is still elusive. Here we show that these materials have vibronic excitations, related to local deformations rotating around JT ions in the dynamic limit, ...

The neutral excitations in two-dimensional electron systems (2DES) confined at MgZnO/ZnO heterojunc- tions were studied by a resonant inelastic light scattering (ILS) technique. At zero magnetic field the ILS spectra of intra- and intersubband collective excitations are detected in the wavelength range close to the ZnO direct band gap. The intersubband spectrum is represented by ...
