Abstract

Structural characterization of a hydrogen sulfate complex with a tren-based urea suggests that the anion is coordinated with six NH center dot center dot center dot O bonds (d(N)center dot center dot center dot(O) = 2.857 (3) to 3.092 (3) angstrom) and one OH center dot center dot center dot O bond (d(O)center dot center dot center dot(O) = 2.57 (2) angstrom) from three receptors; however, in solution the anion is bound within the pseudo-cavity of one receptor.

Uraemic toxins impair skeletal muscle regeneration by inhibiting myoblast proliferation, reducing myogenic differentiation, and promoting muscular fibrosis

Elena Alcalde-Estevez, Patricia Sosa, Ana Asenjo-Bueno, Patricia Plaza, Gemma Olmos, Manuel Naves-Diaz, Diego Rodriguez-Puyol, Susana Lopez-Ongil, Maria P. Ruiz-Torres

Summary: Uraemic toxins increase with declining kidney function in CKD patients, impacting muscular regeneration. High doses inhibit cell proliferation by inactivating cdc2-cyclin B complex, whereas low doses reduce myogenic differentiation and promote fibro-adipogenic differentiation. In vivo studies on uraemic rats also showed impaired skeletal muscle regeneration, even at low concentrations.

Self-Assemblies of Solvates, Ionic Cocrystals, and a Salt Based on 4-{[(4-Nitrophenyl)carbamoyl]amino}-N-(pyrimidin-2-yl)benzene-1-sulfonamide: Study in the Solid and Solution States

Jitendra Nath, Jubaraj B. Baruah

Summary: Solid-state and solution studies were conducted to investigate the interactions between tetrabutylammonium halides and a sulfadiazine-derived urea, influencing the selectivity in the optical detection of fluoride ions. The structures of solvates, ionic cocrystals, and a salt of the sulfadiazine-derived urea were studied, with charge-assisted hydrogen bonds observed in the ionic cocrystals between halide ions and N-H bonds. Furthermore, the formation of an ionic cocrystal with tetrabutylammonium fluoride was not successful, leading to deprotonation to provide a salt.

Research of the Process of Purification of Sulfate Zinc Solution from Iron Ions Using Anodic Oxidation

Lyazat Liakyn, Zhanar Onalbayeva, Natalya Kulenova, Gulzhan Daumova, Sergey Mamyachenkov, Olga Anisimova

Summary: The possibility of using a membrane electrolytic cell to electrochemically oxidize Fe(II) and purify industrial solutions obtained from the leaching of low-grade zinc concentrates is considered. The process parameters for electrooxidation are provided. The feasibility of purifying zinc sulfate solution by hydrolytic purification in a membrane electrolytic cell with an anion-exchange membrane MA-41 TU 2255-062-05761695-2009 is discussed. Direct electrooxidation of iron (II) in sulfate zinc solutions in the anode chamber of a flow membrane electrolyzer ensures good filterability of precipitates after hydrolytic precipitation of iron, allowing the exclusion of the thickening operation from the technological scheme. The degree of iron oxidation during the test period was 99.8-99.9%, and the residual iron concentration in the solution after electrochemical oxidation was less than 0.01 g/dm(3).

Structural, magnetic properties, and electronic structure of Cr1_xMnxO2 solid solution

Hailiang Huang, Tao Lin, Qi Fu, Lu Chen, Ke Chen, Qingyu Hou, Cong Li, Gehui Wen

Summary: Bulk Cr1_xMnxO2 samples were prepared using high pressure synthesis technology, and their crystal structure, magnetic properties, and electronic structure were investigated. The samples exhibited a rutile structure with space group P42/mnm, and the lattice parameter a remained unchanged while the lattice parameter c decreased with increasing Mn dopant content (x) and Metal-Metal bonding along the c-axis. The saturation magnetization of the samples decreased with increasing x. XPS analysis revealed electron transfer between Mn and Cr in Cr1-xMnxO2, with Mn existing as Mn2+ and Mn3+ ions and some Cr being oxidized to Cr6+. The calculated magnetic moment of Cr1-xMnxO2 was in accordance with the experimental data.

Rare-earth induced nonlinear structural evolutions in fluorite solid solution crystals

Qinyu Tang, Fengkai Ma, Zhen Zhang, Dapeng Jiang, Zhonghan Zhang, Adam Strzep, Yangxiao Wang, Huamin Kou, Jingya Wang, Zhenqiang Chen, Yuxin Leng, Liangbi Su

Summary: The study utilizes rare-earth ion doping to modify the chemical composition of Ca1-xSrxF2 solid solutions, resulting in nonlinear changes in spectral properties of the material. X-ray diffraction and density functional theory calculations ruled out the influence of matrix crystals on spectral properties, establishing models for rare-earth ion centers and clusters with nonlinear thermodynamic stabilities. The nonlinearly evolved local structures from cubic to square antiprism sublattice cause the nonlinear variation of spectral properties.

Patryk Niedbala, Kajetan Dabrowa, Agnieszka Cholewiak-Janusz, Janusz Jurczak

Summary: This study presents the synthesis and anion binding studies of a family of homologous molecular receptors based on a DITIPIRAM platform. The host-guest system offers multiple NH hydrogen bond donors to anions, forming stable complexes with carboxylates and chloride anions even in competitive solvent mixtures. Receptors 5 and 6 containing electron-withdrawing F- and -CF3 para-substituents were found to be the most effective derivatives in the series.
