In this work, Cu/Zn/Sn-based ternary and quaternary chalcogenides inks were synthesized via hot injection and/or from ball-milled powders. The used to fabricate thermoelectric generators (TEGs) based on p-type chalcogenide n-type aluminum-doped zinc oxide (AZO) thin films spin-coating magnetron sputtering, respectively. This work highlights the first-ever attempt in a facile scalable method thi...

In the title mol-ecule, C13H10N2S, the dihedral angle between the planes through the non-H atoms of the methylbenzene and thi-azo-lopyridine groups is 36.61 (5)°. In the crystal, the thi-azo-lopyridine groups of inversion-related mol-ecules overlap, with a minimum ring-centroid separation of 3.6721 (9) Å. Furthermore, the methylbenzene groups from neighbouring mol-ecules inter-act edge-to-face ...

Gold nanoparticles (AuNPs) coated with a water-soluble polymer displaying a photoswitchable lower critical solution temperature (LCST) were synthesized, and the photoinduced change in the aggregation state of AuNPs was investigated. The photoactivity of AuNPs was conferred by tethering on the surface a random copolymer of N,N-dimethylacrylamide and N-4-phenylazophenyl acrylamide (P(DMA-co-Azo))...

Magnetic g-Fe2O3@SiO2 core-shell nanocomposite was prepared using Stöber method and functionalized firstly by isopropenyloxytrimethylsilane as a coupling agent to enter active acetylacetone on the surface of nanoparticles, after that synthesized azo dye ligand, 2-(2-benzothiazolyl azo)-4-methoxyaniline. In such way, g-Fe2O3@SiO2-azo hybrid formed. The structure evidenced physical chemical analy...

We report the X-ray crystal structure of a site-selective peptide catalyst moiety and teicoplanin A2-2 complex. The expressed protein ligation technique was used to couple T4 lysozyme (T4L) and a synthetic peptide catalyst responsible for the selective phosphorylation of the N-acetylglucosamine sugar in a teicoplanin A2-2 derivative. The T4L-Pmh-dPro-Aib-dAla-dAla construct was crystallized in ...

Symmetric 2,5-bisazopyrroles 2(a-d) were synthesized by a one-step reaction of substituted phenyl diazonium salts [R'(Ph)N2(+)Cl-] [a, R' = 4-N(CH3)2; b, R' = 2-OH; c, R' = 2-CO2H; d, R' = 4-NO2] with pyrrole under basic conditions. Asymmetric 2,5-bisazopyrroles 3(a-d) were synthesized by reacting substituted phenyl diazonium salts [R''(Ph)N2(+)Cl-] (a, R'' = 4-OCH(3); b, R'' = H; c, R'' = 4-Br...

The first paper of this series (1) reported the results of tests of the carcinogenic activity of cer tam analogs of p-dimethylaminoazobenzene (DAB) in which a pyridine ring or a thiazole ring replaced one of the benzene rings of DAB. Due to the presence of the hetero atom or atoms, position isomers are possible in the heterocyclic analogs, and some of these isomers were synthesized and tested. ...
