Dual redox mediators (RMs) were introduced for Mg-O2 batteries. 1,4-Benzoquinone (BQ) facilitates the discharge with an overpotential reduction of 0.3 V. 5,10,15,20-Tetraphenyl-21H,23H-porphine cobalt(ii) (Co(ii)TPP) facilitates the recharge with an overpotential decrease of up to 0.3 V. Importantly, the two redox mediators are compatible in the same DMSO-based electrolyte.

A novel platinum-mediated process involving intermolecular activation of a C(aryl)-H bond of toluene, intramolecular activation of an imine C(aryl)-Cl bond and formation of a C-C bond is reported.

Generation of azomethine imine and its scope in regioselective 1,3-dipolar cycloaddition (DC) of imine with PhIO toward highly substituted Delta(2)-1,2,4-triazoline, 1,2,4-triazole, and their fused, chiral, and sugar-based analogues are demonstrated.

The structural transformation of substituted hexagonal ferrite powders BaFetoCoTiO~s prepared by mechanical milling, was investigated as a fimction of grinding time by means of MOssbauer spectrometry and static magnetic measurements. A spin reorientation is clearly evidenced from the temperature dependence of the hyperfine parameters and of the initial magnetic permeability on the powder mechan...

Despite the huge success of enantioselective Brønsted acid catalysis, experimental data about structures and activation modes of substrate/catalyst complexes in solution are very rare. Here, for the first time, detailed insights into the structures of imine/Brønsted acid catalyst complexes are presented on the basis of NMR data and underpinned by theoretical calculations. The chiral Brønsted ac...

A series of 5,10,15,20-tetraphenylporphinatozirconium(IV) acetylacetonatophenolates containing different phenols as axial ligands [Zr(TPP)(Y)(X)] (TPP = 5,10.15,20-tetraphenyl-21H, 23H-porphine; Y = acac; X = different phenolates) have been synthesized and characterized by various spectrochemical studies. The complexes were also screened for antimicrobial activities. Antifungal activity of some...

Adenosine monophosphate-activated protein kinase (AMPK) has been identified as one of the major targets for antidiabetic drugs. This study describes two AMPK-activating agents 2-(benzo[d]thiazol-2-ylmethylthio)-6-ethoxybenzo[d]thiazole and 2-(propylthio)benzo[d]thiazol-6-ol, that increase the rate of glucose uptake in L6 myotubes and also augment glucose-stimulated insulin secretion in INS-1E β...

Novel 2-(1,5-bis(aryl)penta-1,4-dien-2-yl)benzo[d]thiazol (5a,b) and 2-(((1S,2S,E)-2(benzo[d]thiazol-2-yl)-1,5-di-arylpent-4-en-1-yl)thio)aniline (6a,b) derivatives were obtained by addition of 2aminobenzothiol to bis-benzylidinecyclobutanones (3a,b). The structures of the obtained compounds were characterized using the spectroscopic methods (NMR, IR, Elemental Analysis). Compounds 5a,b showed ...

Mono-(6-azido-6-deoxy)-β-cyclodextrin (CD) was covalently attached to an alkyne-modified 5-methyl-2-(pyridin-2-yl)thiazol-4-ol yielding a fluorophore containing CD in a click-type reaction. Intermolecular complexes were formed by poly(host-guest)-interactions. The supramolecular structures were characterized by (1)H NMR-ROESY spectroscopy, dynamic light scattering, UV-vis spectroscopy, fluoresc...
