BiFeO3 (BFO), Bi0.86Sm0.07Eu0.07FeO3 (BSEFO), and Bi0.86Sm0.07Cd0.07FeO3 (BSCFO) nano powders were prepared by the sol-gel combustion method and the catalytic performances were evaluated in the acetylation reaction of benzyl alcohol. The physical chemical properties of the catalysts were character...

In the title compound, [Ba(C(14)H(20)O(5))(2)][Co(NCS)(4)], the Ba(II) and Co(II) ions are situated on twofold rotational axes, so asymmetric unit contains half each of the complex cations and anions. The Co(II) ion is coordinated by four N atoms [Co-N 1.83 (2), 1.95 (3) Å] in a distorted tetra-hedral geometry. The Ba(II) ion is coordinated by ten O atoms [Ba-O 2.766 (19)-2.859 (19) Å] from two...

Cross-linking of CD38 on hematopoietic cells induces activation, proliferation and differentiation of mature T and B cells and mediates apoptosis of myeloid and lymphoid progenitor cells. In addition to acting as a signaling receptor, CD38 is also an enzyme capable of producing several calcium-mobilizing metabolites, including cyclic adenosine diphosphate ribose (cADPR). It has been previously ...

Simultaneous generation of H2 fuel and value-added chemicals has attracted increasing attention since the photogenerated electrons holes can be both employed to convert solar light into chemical energy. Herein, for realizing UV-visible-NIR driven dehydrogenation benzyl alcohol (BA) benzaldehydes (BAD) H2, a novel localized surface plasmon resonance (LSPR) enhanced S-scheme heterojunction was de...

Sertraline, a selective serotonin reuptake inhibitor, has been used for the treatment of depression. Although it is generally considered safe, cases of sertraline-associated liver injury have been documented; however, the possible mechanism of sertraline-associated hepatotoxicity is entirely unknown. Here, we report that mitochondrial impairment may play an important role in liver injury induce...

The membrane-bound l-malate oxidoreductase of Azotobacter vinelandii strain O was found to be a flavoprotein-dependent enzyme associated with the electron transport system (R(3)) of this organism. The particulate R(3) fraction, which possessed the l-malate oxidoreductase, carried out the cyanide-sensitive oxidation of l-malate, d-lactate, reduced nicotinamide adenine dinucleotide and nicotinami...

Neotropical orchids of subtribes Stanhopeinae and Catasetinae are exclusively pollinated by euglossine bees (Euglossini). This study determines whether orchids present specific combinations and proportions of chemical odors in order to attract a limited subset of euglossine bee species, thereby avoiding hybridization that may result from the attraction of too many pollinators. Chemical baits of...
