CHEMICAL STABILITY OF SODIUM BETA double prime -ALUMINA ELECTROLYTE IN SULFUR/SODIUM POLYSULFIDE MELTS.

Immersion of sodium beta double prime -alumina electrolyte in sodium polysulfide and pure sulfur melts, at Na/S Battery operation temperatures, showed that the electrolyte was chemically attacked by the melts,and that the extent of degradation was affected by a number of factors, including surface morphology and chemistry of the electrolyte, melt composition, impurity contamination, etc. The corrsosion reactions mostly initiated and concentrated on defected areas, and were catalyzed by the presence of impurities such as water, moist air, oxygen, etc. The corrosion power of sodium polysulfide melts increased with the sulfur content in the range of Na//2S//2 to Na//2S//5.

Long-Life Room-Temperature Sodium–Sulfur Batteries by Virtue of Transition-Metal-Nanocluster–Sulfur Interactions

Room-temperature sodium–sulfur (RT-Na/S) batteries hold significant promise for large-scale application because of low cost of both sodium and sulfur. However, the dissolution of polysulfides into the electrolyte limits practical application. Now, the design and testing of a new class of sulfur hosts as transition-metal (Fe, Cu, and Ni) nanoclusters (ca. 1.2 nm) wreathed on hollow carbon nanospheres (S@M-HC) for RT-Na/S batteries is reported. A chemical couple between the metal nanoclusters and sulfur is hypothesized to assist in immobilization of sulfur and to enhance conductivity and activity. S@Fe-HC exhibited an unprecedented reversible capacity of 394 mAh g?1 despite 1000 cycles at 100 mA g?1, together with a rate capability of 220 mAh g?1 at a high current density of 5 A g?1. DFT calculations underscore that these metal nanoclusters serve as electrocatalysts to rapidly reduce Na2S4 into short-chain sulfides and thereby obviate the shuttle effect.

Synthesis, structure, magnetic and optical properties of ternary thio-germanates: Ln4(GeS4)3 (Ln = Ce, Nd)

Single crystals of two ternary thio-germanates containing rare-earth metals, Ln4(GeS4)3 (Ln = Ce (I), Nd (II)), have been isolated from the reaction of anhydrous rare-earth trichloride (LnCl 3) and ternary sodium thio-germanate (Na2GeS3) in evacuated quartz ampoules. We have determined the crystal structure of the compounds, which are isostructural to La4(GeS4) 3 and crystallize in trigonal system in the space group R3c with the cell dimensions: I, a = b = 19.375(3)A, c = 8.028(2) A, Z = 6; II, a = b = 19.250(3) A, c = 7.949(2) A, Z = 6. The structure is built with the complex network of two independent tricapped trigonal prisms of CeS9, in which Ge atoms occupy tetrahedral holes of sulfur atoms. The bulk synthesis of the two compounds has also been achieved by the stoichiometric combination of the elements. The magnetic and optical properties of the compounds have been investigated. The magnetic moments of 2.32 and 3.49 μB for I and II, respectively, are in good agreement with the theoretical magnetic moments of Ce and Nd in the +3 oxidation state. The optical band gap of I is found to be located around 2.3 eV, while the optical band gap of II lies around 2.62 eV. In addition, Raman spectroscopic characterizations have also been performed for I, II, and La4(GeS4)3.

Alkali-metal thiogermanates: Sodium channels and variations on the La3CuSiS7 structure type

Five new isotypic quaternary chalcogenides containing rare-earth metal atoms crystallizing in the hexagonal noncentrosymmetric space group P63 (No. 173) with the La3CuSiS7 structure type have been synthesized by reacting the appropriate anhydrous rare-earth trichloride with sodium thiogermanate, Na2GeS3. The reaction between LnCl3 and Na2GeS3 in an evacuated fused-silica ampule produced high yields of good-quality crystals of NaLn3GeS7 [Ln = Ce (I), Nd (II), Sm (III), Gd (IV), and Yb (V)], while a similar reaction between EuCl3 and Na2GeS3 yielded a quinary chloride thiogermanate, Na1.2Eu3.4Cl2Ge3S9 (VI), incorporating a cyclic trimeric Ge3S9 building unit and adopting a structure related to La3CuSiS7. The crystal structure of the compounds comprises a complex network of bicapped trigonal-prismatic LnS8 and GeS4 tetrahedra, which creates channels along the [001] direction. The Na+ cations reside in these channels within trigonally distorted octahedral coordination environments, surrounded by six S atoms. For compounds III-V, the temperature dependence of the magnetic susceptibility indicates that these compounds are paramagnetic with μeff. = 1.86, 8.01, and 3.87 μB, for III-V, respectively. The experimental μeff for IV is close to the theoretical value of 7.94 for free Gd3+ ions, while μeff values for III and V deviate from their theoretical values of 0.86 and 4.54 μB for Sm3+ and Yb3+ ions, respectively. These compounds are semiconductors with optical band gaps of around 1.3 eV for III and V. Extended Hückel calculations suggest that the valence band comprises primarily S 3p and the bottom of the conduction band is dominated by empty rare-earth 5d orbitals. Compound VI exhibits a sharp optical absorption of around 2.18 eV, which is attributed to the f → d transition of EuII. The effective magnetic moment of 7.94 μB/Eu is in excellent agreement with the theoretical value of 7.94 μB for the free Eu2+ ion.

Ternary lanthanum sulfide selenides α-LaS2-xSex (022- (X=S, Se)

Mixed lanthanum sulfide selenides LaS2-xSex (02-xSex compounds crystallize in space group P2 1/a, no. 14, and adopt the α-LnS2 (Ln=Y, LaLu) structure type with a pronounced site preference for the chalcogen atoms. The mixed chalcogenides form a complete miscible series with lattice parameters a=820849 pm, b=413425 pm and c=822857 pm (β≈90°) following Vegard's rule. Raman signals indicate the presence of mixed X22- dianions, a species rarely evidenced in literature, besides the well known anions S22- and Se22-. The band gaps of the LaS2-xSex compounds, determined by optical spectroscopy, decrease nearly linearly with increasing amount of selenium.

Multifunctional 5,6-dimethoxybenzo[d]isothiazol-3(2H)-one-N-alkylbenzylamine derivatives with acetylcholinesterase, monoamine oxidases and β-amyloid aggregation inhibitory activities as potential agents against Alzheimer's disease

A series of 5,6-dimethoxybenzo[d]isothiazol-3(2H)-one-N-alkylbenzylamine derivatives were designed, synthesized and evaluated as potential multifunctional agents for the treatment of Alzheimer's disease (AD). The in vitro assays indicated that most of these derivatives were selective AChE inhibitors with good multifunctional properties. Among them, compounds 11b and 11d displayed comprehensive advantages, with good AChE (IC50 = 0.29 ± 0.01 μM and 0.46 ± 0.02 μM, respectively), MAO-A (IC50 = 8.2 ± 0.08 μM and 7.9 ± 0.07 μM, respectively) and MAO-B (IC50 = 20.1 ± 0.16 μM and 43.8 ± 2.0% at 10 μM, respectively) inhibitory activities, moderate self-induced Aβ1–42 aggregation inhibitory potency (35.4 ± 0.42% and 48.0 ± 1.53% at 25 μM, respectively) and potential antioxidant activity. In addition, the two representative compounds displayed high BBB permeability in vitro. Taken together, these multifunctional properties make 11b and 11d as a promising candidate for the development of efficient drugs against AD.
