Giant Optical Activity of Quantum Dots, Rods, and Disks with Screw Dislocations.

Scientific reports

Baimuratov AS, Rukhlenko ID, Noskov RE, Ginzburg P, Gun'ko YK, Baranov AV, Fedorov AV.
PMID: 26424498
Sci Rep. 2015 Oct 01;5:14712. doi: 10.1038/srep14712.

For centuries mankind has been modifying the optical properties of materials: first, by elaborating the geometry and composition of structures made of materials found in nature, later by structuring the existing materials at a scale smaller than the operating...

Note: Gaussian mixture model for event recognition in optical time-domain reflectometry based sensing systems.

The Review of scientific instruments

Fedorov AK, Anufriev MN, Zhirnov AA, Stepanov KV, Nesterov ET, Namiot DE, Karasik VE, Pnev AB.
PMID: 27036840
Rev Sci Instrum. 2016 Mar;87(3):036107. doi: 10.1063/1.4944417.

We propose a novel approach to the recognition of particular classes of non-conventional events in signals from phase-sensitive optical time-domain-reflectometry-based sensors. Our algorithmic solution has two main features: filtering aimed at the de-nosing of signals and a Gaussian mixture...

Chiral quantum supercrystals with total dissymmetry of optical response.

Scientific reports

Baimuratov AS, Gun'ko YK, Baranov AV, Fedorov AV, Rukhlenko ID.
PMID: 26991549
Sci Rep. 2016 Mar 18;6:23321. doi: 10.1038/srep23321.

Since chiral nanoparticles are much smaller than the optical wavelength, their enantiomers show little difference in the interaction with circularly polarized light. This scale mismatch makes the enhancement of enantioselectivity in optical excitation of nanoobjects a fundamental challenge in...

A curious interplay in the films of N-heterocyclic carbene Pt(II) complexes upon deposition of alkali metals.

Scientific reports

Makarova AA, Grachova EV, Niedzialek D, Solomatina AI, Sonntag S, Fedorov AV, Vilkov OY, Neudachina VS, Laubschat C, Tunik SP, Vyalikh DV.
PMID: 27151364
Sci Rep. 2016 May 06;6:25548. doi: 10.1038/srep25548.

The recently synthesized series of Pt(II) complexes containing cyclometallating (phenylpyridine or benzoquinoline) and N-heterocyclic carbene ligands possess intriguing structures, topologies, and light emitting properties. Here, we report curious physicochemical interactions between in situ PVD-grown films of a typical representative...

3D printing of mineral-polymer bone substitutes based on sodium alginate and calcium phosphate.

Beilstein journal of nanotechnology

Egorov AA, Fedotov AY, Mironov AV, Komlev VS, Popov VK, Zobkov YV.
PMID: 28144529
Beilstein J Nanotechnol. 2016 Nov 21;7:1794-1799. doi: 10.3762/bjnano.7.172. eCollection 2016.

We demonstrate a relatively simple route for three-dimensional (3D) printing of complex-shaped biocompatible structures based on sodium alginate and calcium phosphate (CP) for bone tissue engineering. The fabrication of 3D composite structures was performed through the synthesis of inorganic...

The influence of phthalocyanine aggregation in complexes with CdSe/ZnS quantum dots on the photophysical properties of the complexes.

Beilstein journal of nanotechnology

Martynenko IV, Orlova AO, Maslov VG, Fedorov AV, Berwick K, Baranov AV.
PMID: 27547619
Beilstein J Nanotechnol. 2016 Jul 13;7:1018-27. doi: 10.3762/bjnano.7.94. eCollection 2016.

The formation of nonluminescent aggregates of aluminium sulfonated phthalocyanine in complexes with CdSe/ZnS quantum dots causes a decrease of the intracomplex energy transfer efficiency with increasing phthalocyanine concentration. This was confirmed by steady-state absorption and photoluminescent spectroscopy. A corresponding...

Excitons in gyrotropic quantum-dot supercrystals.

Optics letters

Baimuratov AS, Shlykov AI, Zhu W, Leonov MY, Baranov AV, Fedorov AV, Rukhlenko ID.
PMID: 28957249
Opt Lett. 2017 Jul 01;42(13):2423-2426. doi: 10.1364/OL.42.002423.

We use quantum theory of molecular crystals to study collective excitations (excitons) of gyrotropic quantum-dot (QD) supercrystals with complex lattices consisting of two or more sublattices of semiconductor QDs. We illustrate the potentials of our approach by applying it...

Dimensional Effects on the Charge Density Waves in Ultrathin Films of TiSe.

Nano letters

Nano Lett. 2016 Oct 12;16(10):6331-6336. doi: 10.1021/acs.nanolett.6b02710. Epub 2016 Sep 23.

Charge density wave (CDW) formation in solids is a critical phenomenon involving the collective reorganization of the electrons and atoms in the system into a wave structure, and it is expected to be sensitive to the geometric constraint of...

Fluorescence energy transfer in quantum dot/azo dye complexes in polymer track membranes.

Nanoscale research letters

Gromova YA, Orlova AO, Maslov VG, Fedorov AV, Baranov AV.
PMID: 24172215
Nanoscale Res Lett. 2013 Oct 31;8(1):452. doi: 10.1186/1556-276X-8-452.

Fluorescence resonance energy transfer in complexes of semiconductor CdSe/ZnS quantum dots with molecules of heterocyclic azo dyes, 1-(2-pyridylazo)-2-naphthol and 4-(2-pyridylazo) resorcinol, formed at high quantum dot concentration in the polymer pore track membranes were studied by steady-state and transient...

Spin-orbit interactions and the nematicity observed in the fe-based superconductors.

Physical review letters

High-resolution angle-resolved photoelectron spectroscopy is used to examine the electronic band structure of FeTe_{0.5}Se_{0.5} near the Brillouin zone center. A consistent separation of the α_{1} and α_{2} bands is observed with little k_{z} dependence of the α_{1} band. First-principles...
