Abstract:

B a c k g r o u n d . The self-concept of a person is a phenomenon that includes a person's ideas about himself and his own assessment of these ideas. Representatives of various directions in psychology emphasized that a positive self-concept of an individual is a condition for a fully functioning and prosperous individual who is fully aware of his self, knows and knows how to use his advantages and disadvantages, and strives to realize his potential (K. Rogers, R. Burns, J. Nezlek, R. Plesko, etc.). R. Burns was the first to propose the division of self-concept orientation into positive and n

SynopsisA sequence of transformations of the type Y = (I + o(1))Z is developed for the system Y′(x) = {Λ(x) + R(x)}Y(x), where Λ is diagonal. The transformations bring in the derivatives of R in succession until the Levinson form is obtained when a given derivative is reached. This theory covers rapidly varying coefficients and it extends results which are known for constant Λ.

For the Li-Ti-O pseudobinary systems some complex oxides may be formed during phase transformation that occurs at significantly lower temperatures compared to pure TiO2 or TiO2-Al2O3 mixtures. Al2O3 doping in TiO2 only increases the anatase-to-rutile transition rate once

We report an unusual transformation where the transient formation of a nitrene moiety initiates a sequence of steps leading to remote oxidative C–H functionalization (R–CH3 to R–CH2OC(O)R’) and the concomitant reduction of the nitrene into an amino group. No external oxidants or reductants are needed for this formal molecular comproportionation. Detected and isolated intermediates and computational analysis suggest that the process occurs with pyrazole ring opening and recyclization.

Abstract The P(III)trimethylsilylesters. RP(OSiMe3)2 (R = Me, Ph) and MeP(OBu")(OSiMe3). were synthesized by the silylation of the appropriate P(III)(:O)(H) compound with dimethylaminotrimethylsilane. Their reaction with hexafluoroacetone was studied with a view of synthesizing P-functional λ5P-trimethylsiloxy phosphoranes. From RP(OSiMe3)2 the expected bis(trimethylsilyl) perfluoropinacolyl phosphoranes, RP(OSiMe3)2(pfp = perfluoropinacolyl). were obtained. Their stability was limited, and transformation to the known λ4P species. RP(:O)(pfp), was observed. From the mixed P(III) ester, MeP(OBu

Abstract:

Abstract Oxygen-vacancy-induced topotactic phase transformation between the ABO2.5 brownmillerite structure and the ABO3 perovskite structure attracts ever-increasing attention due to the perspective applications in catalysis, clean energy field, and memristors. However, a detailed investigation of the electronic-structure evolution during the topotactic phase transformation for understanding the underlying mechanism is highly desired. In this work, multiple analytical methods were used to explore evolution of the electronic structure of SrFeO3−x thin films during the topotactic phase transfor

A Ernst-like matrix representation of (3+d)-dimensional Einstein–Kalb–Ramond theory is developed. The analogy with the Einstein and Einstein–Maxwell–Dilaton–Axion theories is discussed. The subsequent reduction to two dimensions is considered. It is shown that, in this case, the theory allows two different Ernst-like d×d-matrix formulations: the real nondualized target space, and the Hermitian dualized nontarget space one. The O(d, d)-symmetry is written in an SL (2,R) matrix-valued form in both cases. The Kramer–Neugebauer transformation, which algebraically maps the nondualized Ernst potenti

Abstract:

Nanostructured hexagonal rare-earth orthoferrites (h-RfeO3, R = Sc, Y, Tb-Lu) are well known as a highly effective base for visible-light-driven heterojunction photocatalysts. However, their application is limited by metastability, leading to difficulties in synthesis due to the irreversible transformation to a stable orthorhombic structure. In this work, we report on a simple route to the stabilization of h-YbFeO3 nanocrystals by the synthesis of multiphase nanocomposites with titania additives. The new I-type heterojunction nanocomposites of o-YbFeO3/h-YbFeO3/r-TiO2 were obtained by the glyc

Benzophenone Ph2C=O is able to “store” the silaethene Me2Si=C(SiMe3)2 (1). produced from Me2SiX-CLi(SiMe3)2 (X = F. Br, Ph2PO4), under formation of a [2+4] cycloadduct (2b). At about 100 °C, 2b by way of 1 transfers into the [2+2] cycloadduct of 1 and Ph2C=O (3b), which in the course of transformation decomposes visibly (in the absence of Me3SiCl) or only by traces (in the presence of Me3SiCl) to secondary products. In the presence of ROH (R = H. Me. tBu. MeCO) or PhN = NSiMe3 or RN3 (R = tBu. Me3Si) or 2,3-dimethylbutadiene (dmb) about 100 °C 2b and 3b form by way of 1 insertion products of 1

For instance, few-layer black phosphorus and arsenic have thickness-dependent direct bands spanning the visible and near infrared, as well anisotropic transport properties.
