Baku State University (BSU) (Azerbaijani: Bakı Dövlət Universiteti (BDU)) is a public university located in Baku, Azerbaijan. Established in 1919 by the Parliament of Azerbaijan Democratic Republic, the University started with faculties of history and philology, physics and mathematics, and law and medicine, with an initial enrollment of 1094. The first rector of BSU was V.I.Razumovsky, a former professor of surgery at Kazan University.In 1930, the government ordered the University shut down in accordance with a reorganization of higher education, and the University was replaced with the Supreme Pedagogical Institute. However, in 1934 the University was reestablished again and continued to work through the difficult years of World War II experiencing a shortage of faculty members.By its 40th anniversary in 1959, the University already had 13 faculties. The Azerbaijan Medical University and Azerbaijan State Economic University were both spun-offs of the original respective faculties at BSU.Among the graduates of BSU were two former presidents of Azerbaijan, Abulfaz Elchibey and Heydar Aliyev. The former graduated from the Faculty of Arabic Language and Literature, while the latter, who dominated Azerbaijan's political life for over 30 years, from the Faculty of History. Nobel Prize-winning physicist Lev Landau studied at BSU between 1922 and 1924.BSU is the only university from Azerbaijan ranked by international ranking organizations, such as University Ranking by Academic Performance and currently ranks at 1872 in the University Ranking by Academic Performance.
Self-assembly of phenylsiloxanolate/acetylacetonate copper complexes resulted in the solvent-controlled (MeCN/EtOH vs DMF or CH2Cl2) isolation of two types of cage complexes. Depending on (Cu6 or Cu8) nuclearity, molecular architectures differ in the number of acetylacetonate species (two or four), while keeping the same sandwich-type cage structure with a pair of Si5-cyclic ligands. The complexes are active precatalysts in the oxidative amidation (OA) reaction of benzylic alcohols and amine hydrochlorides. The developed catalytic protocol led to amides in good to excellent yields with only 100 ppm of Cu loading. The catalysts were also successfully evaluated in the oxidation of aniline to nitrobenzene with use of tert-butyl hydroperoxide (TBHP).
Triboelectric nanogenerators (TENGs) are limited by poor charge retention and unstable output. This study investigates the effect of graphene oxide (GO) incorporation and environmental humidity on a nylon/polysiloxane-based TENG. Structural and chemical properties were analyzed using XRD, Raman, and FTIR, while SEM and photoluminescence (PL) were used to examine morphology and charge-trapping behavior. Electrical performance was evaluated through dielectric and TENG output measurements. An optimal GO loading of 0.05 wt
Pyrimidine-based derivatives are widely recognized for their diverse biological functions, which arise from their distinctive chemical structures and broad spectrum of pharmacological activities. Consequently, they have attracted sustained interest in the fields of heterocyclic chemistry and medicinal chemistry. From this perspective, the present article highlights innovative synthetic approaches to a wide range of pyrimidine-based compounds, emphasizing their therapeutic significance in the treatment of various diseases, including cancer, infectious diseases and metabolic disorders, as well as recent advances in pharmacological research. The review discusses the development and application of pyrimidine derivatives as anti-tuberculosis and anti-inflammatory agents, alongside their emerging potential as antitumor compounds. In the context of the twenty-first century, the growing prevalence of drug-resistant bacterial infections, which pose a serious threat to global health, underscores the urgent need for novel antibacterial agents. Pyrimidine-containing compounds represent a promising class of candidates in this regard. Moreover, because the pyrimidine scaffold constitutes a key structural motif in many endogenous biomolecules, pyrimidine derivatives possess a strong ability to interact with genetic material, enzymes and other cellular biopolymers. Accordingly, this article provides a comprehensive overview of recent literature on the synthesis, biological evaluation and therapeutic applications of pyrimidine-based drugs. The presented material also summarizes literature data on clinically important pharmaceuticals derived Pralsetinib, Nilotinib, Imatinib, Brodimoprin and Eprizole, which are widely used in the treatment of infectious and non-infectious diseases, as well as in antibiotic, antitumor, antiviral, anticancer and antiinflammatory therapies.
This paper presents the results of a comprehensive study of solid-phase equilibria in the Bi2S3-Bi2Se3-BiI3 system and the thermodynamic properties of the intermediate phases Bi19S27(1-& khcy;)S & iecy;27 & khcy;I3. The investigations were carried out using differential thermal analysis (DTA), X-ray diffraction (XRD) and electromotive force (EMF) measurements of concentration cells of the type (-) Bi (solid) / liquid electrolyte, Bi3+ / (Bi in alloy) (solid) (+) within the temperature range 300-370 K, with morpholine formate ionic liquid as the electrolyte. Based on the experimental data, a solid-phase equilibria diagram of the Bi2S3-Bi2Se3-BiI3 system was constructed, according to which it is characterized by the formation of a continuous series of solid solutions along the BiSI-BiSeI section and a wide homogeneity area based on Bi19S27I3. From the EMF measurement data, the partial thermodynamic functions of bismuth in solid solutions based on Bi19S27I3 were calculated. Using a fragment of the phase diagram of the quaternary Bi-S-Se-I system, the potential-forming reactions responsible for the indicated partial molar functions were determined and the standard thermodynamic functions of formation and standard entropies of the ternary compound Bi19S27I3 and the solid solutions Bi19S27(1-& khcy;)S & iecy;27 & khcy;I3 (x = 0.2, 0.4, 0.6) were calculated. In the calculations, in addition to the authors' own data, literature data on the corresponding thermodynamic functions of the BiSI compound, the solid solutions BiS1-& khcy;SexI and the S1-xSex alloys were used.
Axial-vector hadronic molecules M-AV = Upsilon B-c(-) and (M) over tilde (AV) = eta(b) B-c*(-) with the quark content bb (b) over bar(c) over bar are studied using QCD sum rule method. The spectroscopic parameters of these molecules are computed in the context of the two-point sum rule method. Predictions for their masses are identical to each other and confirm that they are structures unstable against dissociations to ordinary heavy mesons. We evaluate the width of the state M-AV and assume that it is equal to that of (M) over tilde (AV). To this end, we explore its dominant decay channels M-AV -> Upsilon B-c(-) and M-AV -> eta(b) B-c*(-). There also are subleading modes of M-AV generated due to annihilation of b (b) over bar quarks. We consider decays of the molecule MAV to pairs of the mesons B*(-)(D) over bar (0), (B) over bar*D-0(-), B-(D) over bar*(0), (B) over bar (0) D*(-), (B) over bar (s)*(0) D-s(-), and (B) over bar (0)(s) D-s*(-). To find strong couplings at the M-AV-meson-meson vertices which determine the partial widths of these processes, we apply QCD three-point sum rule approach. The mass m = (15,800 +/- 90) MeV and width Gamma [M-AV] = (114 +/- 17) MeV of the molecule M-AV are useful for experimental studies of fully heavy molecular structures at ongoing and planning experiments.
