摘要：
High-temperature degradation of the plasma sprayed LaMA coating before and after in-situ laser-glazing under CMAS attacks at 1350 degrees C for 1 h, 12 h and 48 h was comparatively investigated. Results indicate that a dense laser-glazed top layer was successfully created in-situ for a similar to 1 mm thick LaMA coating. It behaved as a sealing layer and reservoir of Al3+, Mg2+ and La3+. Melted CMAS penetration was accordingly effectively arrested accompanied by crystallizations of the CaAl2Si2O8 anorthite, MgAl2O4 spinel and Ca2La8(SiO4)(6)O-2 apatite. CMAS-induced degradation mainly occurred near the surface of the laser-glazed dense LaMA top layer. While significant penetration of the melted CMAS along the entire thickness occurred to the as-sprayed LaMA coating without laser-glazing treatments after 48 h degradation. Ca2La8(SiO4)(6)O-2 apatite phase did not crystallize for the as-sprayed LaMA due to the much reduced local La3+ concentration in melted CMAS resulted from its porous microstructure. Effects of laser-glazing on the CMAS-induced degradation of the plasma sprayed LaMA was carefully analyzed and discussed in terms of the coating's chemical composition, microstructure and surface physical chemistry characteristics base on XRD, SEM/EDS and TEM results.

Crystal data for the complex: monoclinic, space group P2(1)/n, a = 14.9738(5), b = 13.5469(4), c = 23.0683(7) angstrom, beta= 103.950(3)degrees, V= 4541.4(3) angstrom(3) , D-c = 1.511 g/cm(3), Z = 2,mu(MoK alpha) = 1.620 mm(-1), F(000) = 2088, the final R= 0.0318 and wR = 0.0727. The Tb(III) ion is coordinated by eight atoms to give a distorted square antiprism coordination geometry. The complex shows three fluorescence emission bands arising from the transitions of Tb3+: D-5(4) -> F-7(6) (490 nm), D-5(4) -> F-7(5) (545 nm) and D-5(4) -> F-7(4) (584 nm).

摘要：
A kind of coenzyme A (CoA)-silver coordination complex (CoA-Ag) was in-situ developed and verified to accelerate the electron transferring and electrochemical catalysis of H2O2 decomposition to enhance the cathode ECL intensity of CdTe@CdS QDs. Afterward, a convenient label-free signal-on ECL approach was constructed for CoA detection with excellent specificity. In addition, the unique ECL enhancing phenomenon was also proposed to assay the enzymatic activity of histone acetyltransferases (HAT) and screen relevant inhibitors, exhibiting a promising potential in the practical application of biochemical research, disease diagnosis and drug discovery.
