Crystal structure and properties of novel oxide Sm0.9Ca1.1Fe0.7Co0.3O4–δ

Received: 13.11.2018. Accepted: 05.12.2018. Published: 31.12.2018.Sm0.9Ca1.1Fe0.7Co0.3O4–δ oxide with the K2NiF4‑type structure was prepared using a glycerin-nitrate technique. The XRD pattern of Sm0.9Ca1.1Fe0.7Co0.3O4–δ was refined by the Rietveld method within an orthorhombic structure (space group Bmab). The electrical conductivity, Seebeck coefficient, and thermal expansion of Sm0.9Ca1.1Fe0.7Co0.3O4–δ were measured depending on temperature in air. The change of oxygen nonstoichiometry determined by TGA in air does not exceed 0.01. The oxygen content in Sm0.9Ca1.1Fe0.7Co0.3O4–δ determined by the reduction in a hydrogen flux is equal to 3.96 ± 0.01. The positive value of Seebeck coefficient indicates that the predominant charge carriers in the oxide studied are electron holes.This work was supported in parts by Act 211 Government of the Russian Federation, agreement 02.A03.21.0006

A Study of the Crystal Structure of SmCaCo1−xFexO4−δ and Sm0.9Ca1.1Fe1−yCoyO4−δ Solid Solutions

Complex oxides with general compositions SmCaCo1−xFexO4−δ and Sm0.9Ca1.1Fe1−yCoyCO4−δ are synthesized using the glycerol-nitrate technique at 1100 °C in air. By powder X-ray diffraction it is determined that SmCaCo1−xFexO4−δ solid solutions exist in a composition range 0 ≤ x ≤ 0.3 and Sm0.9Ca1.1Fe1−yCoyO4−δ solid solutions exist in a composition range 0 ≤ y ≤ 0.7. The samples with high concentrations of cobalt ions are found to crystallize in the tetragonal unit cell (space group I4/mmm), whereas the solid solutions enriched with iron ions have the orthorhombic structure (space group Bmab). For all single phase samples the unit cell parameters and volume and the structural parameters (atomic coordinates and bond lengths) are calculated by the full-profile Rietveld method. © 2019, Pleiades Publishing, Ltd

CRYSTAL STRUCTURE AND PHYSICOCHEMICAL PROPERTIES OF EuCoXFe1-XO3-Δ (0≤X≤1) COMPLEX OXIDES

The XRD patterns of single phase EuFe1-xCoxO3-δ (0≤x≤1) solid solutions were indexed in the orthorhombic structure (sp. gr. Pbnm). Thermal expansion, electrical conductivity and Seebeck coefficient of EuFe1-xCoxO3-δ were measured within the temperature range of 25-1100ºС in air

APPLICATION OF INTENSIVE LIGHT RADIATION IN THE PATIENT WITH ERYTHEMATOTELANGIECTATIC ROSACEA

We present a description of the clinical case of a patient with an erythematotelangiectatic type of rosacea. Rosacea is a chronic recurrent dermatosis, characterized by skin lesions of the face in the  form of erythema and papulopustular elements, which has  polyethological origin. The disease occurs more frequently in women  aged 30-50 years who have a certain genetic predisposition to  transient reddening of the skin of the face or less often of the neck  and the decollete zone. It is believed that the dermatosis is more  likely to affect the I and II phototypes, but the disease can occur in  any skin phototype. The patient came to the clinic with complaints  about rashes in the chin and nasolabial triangle, flushing of the face,  accompanied by tingling and burning. The patient turned to the clinic with complaints about rashes in the chin and nasolabial triangle,  flushing of the face, accompanied by tingling and burning. She never consulted a dermatologist before. A diagnosis was made: “erythematotelangiectatic type of rosacea” (according to the  classification proposed by the USA National Rosacea Society, stage I  — persistent erythema and telangiectasia). Using the scale of diagnostic evaluation of rosacea, it was evaluated at 12 points.  There are many approaches to the treatment of rosacea. Drug  therapy is divided into systemic, external and complex. Systemic therapy has a number of side effects, so for light and medium-to- severe rosacea, only external therapy is more often prescribed.  Because of the presence of pathologically altered vessels, the low  efficacy of metronidazole, the patient was assigned a course of  phototherapy with intense incoherent pulsating light at standard  parameters. There was a significant improvement after two  procedures, but vessels smaller than 0.4 mm remained intact, so the duration of the first pulse was increased in order to influence small- caliber vessels. Individual selection of parameters (duration of the first impulse and fluence) was made based on the dermatoscopic picture and patient’s phototype, which resulted in a significant  clinical effect and persistent remission. Using the scale of diagnostic  evaluation of rosacea it was evaluated at 1 point after treatment.  This clinical case demonstrates the effectiveness of phototherapy  with intense incoherent pulsating light with individual selection of the duration of the first pulse and energy density in patients with  erythematotelangiectatic rosacea. In IPL-treatment schemes, it is  desirable to select individual parameters for the duration of the first pulse and the energy density, based on the features of the dermatoscopic picture and skin phototype of each individual patient

STRUCTURE AND PROPERTIES OF EuFe1-xCoxO3-δ (0≤X≤1) COMPLEX OXIDES

EuFe1-xCoxO3-δ complex oxides with the perovskite-type structure have been prepared using a glycerin-nitrate technique at 1100°C in air. According to the XRD results of quenched samples, single-phase solid solutions EuFe1-xCoxO3-δ with the orthorhombic structure (space group Pbnm) were formed within
