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. ...

Rare earth oxides (RE2O3) were found to react with glycine in an aqueous medium at rather low temperatures (60°С–120°С), forming rare earth oxohydroxyglycinates, RE2O(OH)3(NH2CH2COO)·H2O, with a previously unknown crystal structure. The structure of the europium oxohydroxyglycinate was determined using powder X-ray diffraction. Its layered structure and ability for anion exchange under mild conditions, namely the ...

The early stage of molecular oxygen adsorption on the Ag(100) surface was reexamined with scanning tunneling microscopy (STM) and density functional theory. Using an oxygen-functionalized STM tip, we demonstrated that the simple interpretation of the individual objects randomly distributed over the surface as chemisorbed oxygen atoms is incompatible with the cross-shaped structures observed in atomic-resolution ...

Adsorption of molecular oxygen on the Ag(111) surface at room temperature has been studied using scanning tunneling microscopy (STM), Auger-electron spectroscopy (AES), temperature programmed desorption (TPD), and density functional theory (DFT). In the early stage of adsorption, the STM images show formation of a disordered phase in the form of dark spots (local oxide (Ag6O6) ...

Adsorption of iodine on Ag(110) has been studied in ultra high vacuum with room temperature scanning tunneling microscopy (STM) and low energy electron diffraction (LEED) in combination with density functional theory (DFT) calculations. It was found that at low coverages iodine forms structure. Further adsorption of iodine leads to compression of atoms in the troughs along direction and formation of domain walls separating domains. As ...

Standard e-beam lithography system is used for writing a set of charged regions in glass, which provide patterned
area possessing electric-field-induced quadratic optical nonlinearity. Patterned glass provides second optical harmonic generation (SHG) under a normal incident fundamental wave. Grating-like regions with periodicity from 2 to 32 μm demonstrate diffractionlike radiation patterns due to the interference of the second harmonic waves in the ...

The phenomenon of mode hybridization in the exchange-coupled two-layer antiferromagnet|ferromagnet structure has been theoretically investigated. Expressions describing the dependence of the resonant frequencies of magnetization oscillations on the external magnetic field have been obtained by the method of Hamiltonian formalism. The effect of the coupling strength between the ferro- and antiferromagnetic layers on the width ...

The behavior of silver nitrate in non-aqueous liquid oligomeric media—aromatic and aliphatic diglycidyl ethers and aliphatic diamine—hasbeen investigated. By employing UV–visible spectrophotometry and dynamic light scattering, it has been shown that in diglycidyl oligomers,regardless of the nature of the monomeric unit, the formation of silver nanoparticles occurs, and the kinetics of this process has been ...

Structural transformations under chlorine adsorption on the Ag(100) surface have been studied with scanning tunneling microscopy (STM) and within the density functional theory (DFT) calculations. The DFT method reveals that the preferable adsorption site of chlorine atoms is the fourfold hollow position. The STM technique is used to study the disorder-order structural phase transition occurring ...

The atomic structure of the Ag(111)-p(4 × 4)-O phase was reexamined with scanning tunneling microscopy (STM) and density functional theory. We discovered two different phases with the same (4 × 4) periodicity and demonstrated that the accepted Ag6 model is incompatible with high-resolution oxygen-sensitive STM images. Using bias dependencies of the STM images, we have shown ...

Currently, non-proteinogenic α-amino acids (α-AAs) have attracted increasing interest in bio- and medicinal chemistry. In this context, the first protocol for the asymmetric synthesis of artificial α-AAs featuring a 3,4-dihydroisoquinolone core with two stereogenic centers was successfully elaborated. A straightforward Rh(III)-catalysed C–H activation/annulation reaction of various aryl hydroxamates with a set of robust and readily ...

Herein, we present a facile synthesis of amide-type water-soluble fullerene derivatives decorated with five residues of amino acids. As compared to the previously developed approaches, the proposed method enables usage of a broad range of amino acids, includ-ing those unstable under Friedel-Crafts reaction conditions. Furthermore, it is fully tolerant to the nature of the sixth ...

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) ...
