Аннотация: The structural as well as electronic properties of PtPd nanoparticles (NPs) were investigated by using molecular dynamics simulations and density functional theory calculations. A wide range of NPs of different sizes (from 1.5 to 4 nm), structures (core–shell, alloy, Janus), and compositions were taken into consideration. It was shown that PtPd NPs of less than ∼2.0 nm are prone to structural transformations to icosahedral (Ih) shape, regardless of their initial structure and composition. On the other hand, for NPs of size ∼2.5 nm, the increase of temperature up to 700–900 K leads to structural changes only for compositions close to 40% Pt, which corresponds to energetic minimum for Pt@Pd NPs. The Ih form of Pd@Pt NPs with monolayer thickness of Pt on the surface appears to have the most negatively charged surface which makes this kind of NPs the best candidate for catalysis application.

The technology and setup for high-throughput synthesis of endohedral metal fullerenes / D. I. Chervyakova [et al.] // Proceedings of the Scientific-Practical Conference "Research and Development - 2016". - 2016. - P. 481-489, DOI 10.1007/978-3-319-62870-7_51 . - ISSN 978-3-319
Аннотация: The article presented the technology and setup for high-throughput synthesis of carbon nanostructures. It was shown that the plasma-chemical synthesis of fullerenes and endohedral metallofullerenes (EMF) in high-frequency arc discharge can be controlled by changing helium pressure in the chamber. The methods of extraction using Lewis acids and separation of individual EMF by HPLC were suggested as the most effective.

Transition metal dihalides -- Monolayers -- DFT -- Hubbard correction -- Band structure
Аннотация: Electronic structure and magnetic properties of the family of first-row transition metal dihalides (TMHal2, TM = V, Cr, Mn, Fe, Co, Ni; H = Br, I) monolayers were studied by means of density functional theory. Strong electron correlations were taken into account by implementing Hubbard U correction in a simplified scheme proposed by Dudarev et al. (Ueff). Ueff correction essentially affects electronic structure of TMHal2 widening the band gap and witnessing their highly spin-polarized nature. Two different ligand orientations namely, H and T configurations of monolayers were considered. Unlike others, FeHal2 monolayers tend to form H structure when Ueff correction is included. © 2019 Elsevier Ltd

Carbon nanotubes -- LSMO -- Interface -- Spin polarization
Аннотация: Atomic and electronic structure of LSMO-based composites with carbon nanotubes were studied by means of density functional theory with respect to the termination of LSMO surface. The deformation of the tubes caused by the lattice mismatch with the substrate leads to a major change in their electronic structure. The surface terminated with Mn-O layer provides much stronger interaction with carbon nanotubes than Sr-O terminated one does. The interaction with transition metal atoms is essential for spin polarization of the nanotube while no spin injection was observed for Sr-O-supported tubes. © 2017 Elsevier B.V.

Graphene nanoribbons -- DFT -- LSMO thin films -- Induced spin polarization -- h-BN nanoribbons -- Half-metal
Аннотация: Induced spin polarization of π-conjugated carbon and h-BN low dimensional fragments at the interfaces formed by deposition of pentacene molecule and narrow zigzag graphene and h-BN nanoribbons on MnO2-terminated LSMO(001) thin film was studied using GGA PBE+U PAW D3-corrected approach. Induced spin polarization of π-conjugated low-dimensional fragments is caused by direct exchange with Mn ions of LSMO(001) MnO-derived surface. Due to direct exchange, the pentacene molecule changes its diamagnetic narrow-band gap semiconducting nature to the ferromagnetic semiconducting state with 0.15 eV energy shift between spin-up and spin-down valence bands and total magnetic moment of 0.11 μB. Direct exchange converts graphene nanoribbon to 100% spin-polarized half-metal with large amplitude of spin-up electronic density at the Fermi level. The direct exchange narrows the h-BN nanoribbon band gap from 4.04 to 1.72 eV in spin-up channel and converts the h-BN ribbon semiconducting diamagnetic nature to a semiconducting magnetic one. The electronic structure calculations demonstrate a possibility to control the spin properties of low-dimensional π-conjugated carbon and h-BN fragments by direct exchange with MnO-derived LSMO(001) surface for spin-related applications.

Transition metal trihalides -- Magnetic properties -- Thermoelectric -- conversion -- Density functional theory
Аннотация: Using DFT GGA calculations, electronic structure and magnetic properties of wide family of transition metal trihalides (TMHal3) (Zr, Ti and Nb iodides, Mo, Ru, Ti and Zr bromides and Ti or Zr chlorides) are investigated. These structures consist of transition metal atoms chains surrounded by halides atoms. Chains are connected to each other by weak interactions. All TMHal3 compounds were found to be conductive along chain axis except of MoBr3 which is indirect gap semiconductor. It was shown that NbI3 and MoBr3 have large magnetic moments on metal atoms (1.17 and 1.81 µB, respectively) but other TMHal3 materials have small or zero magnetic moments. For all structures ferromagnetic and anti-ferromagnetic phases have almost the same energies. The causes of these properties are debated.

Аннотация: Geometric, electronic and magnetic structure of planar slabs consisting of magnetite Fe3O4, titanium and gold layers are investigated by DFT-GGA calculations. It is assumed that these slabs can be used to simulate the upper layers of magnetite nanoparticles covered with an intermediate layer of titanium and a gold layer on the surface. Specific energies and spreading parameters (wettability) of the magnetite-gold, magnetite-titanium and titanium-gold interfaces are calculated. The specific energy and spreading parameter of the magnetite-gold interface is found to be negative, while these values of the magnetite-titanium (for thin Ti layer) and magnetite-titan-gold interfaces are significantly positive. This allows us to hope that the intermediate thin layer of titanium at the boundary between the surface of the magnetite nanoparticle and the gold layer stabilizes this three-layer structure and allows obtaining magnetite nanoparticles covered with continuous gold coating.

Аннотация: In this work, through the technology of producing endohedral metallofullerene in macroscopic quantities, the process of pressure polymerization of Sc2C2@C82 and their mechanical properties have been investigated in detail using a set of experimental and theoretical methods. The crucial role of endohedral atoms is demonstrated by comparison with pristine fullerenes. It is shown that the embedding of Sc2C2 complex inside a fullerene significantly facilitates the polymerization process which finally leads to the highly rigid material at high pressures.

Аннотация: The nature of the formation of a chemical bond at the magnetite-gold interface has been studied. The geometric structure and the electronic and magnetic properties of plane layers consisting of magnetite Fe3O4 and gold have been investigated using the DFT-GGA calculation. It has been found that the specific energy and the wetting parameter of the magnetite-gold interface are negative, which leads to the island growth of small Au particles on the Fe3O4 surface. The role of an intermediate thin titanium layer between magnetite and gold has been discussed. The specific energy and wetting parameter of the magnetite-titanium (for thin Ti layers) and magnetite-titanium-gold interfaces are positive. It has been suggested that an intermediate thin titanium layer at the interface between the magnetite nanoparticle surface and the gold layer will make it possible to obtain magnetite nanoparticles with a continuous gold coating.

Аннотация: Electronic structure and spin-related properties of CoI2/NiI2 heterostructure were studied by means of density functional theory. It was shown that the electronic structure at the Fermi level can be characterized by a band gap. The effect of the external electric field on charge transfer and electronic properties of the CoI2/NiI2 interface was investigated, and it was found that band gap width depends on the strength of the applied electric field, switching its nature from semiconducting to a half-metallic one. An easy control of the electronic properties and promising spin-polarized nature of the CoI2/NiI2 spinterface allows the heterostructure to be used in spin-related applications.
