Two crystallographically independent molecules A and B but with similar structural details were also found in 1.An ORTEP drawing of the molecule A structure of 1 is shown in Figure 1.The basic skeleton of 1 exhibits a distorted octahedral geometry of the metal centers with the platinum atoms in a mutually trans disposition and the four silver 。 A new ECL method for the determination of Sudan I was developed with ...

Both complexes show distorted octahedral geometry with three carbonyl ligands groups being fac-oriented around the Re(I)center. Which are smaller than the ideal angle of 90°adopted in octahedral geometry as required by the steric requirement of the chelating bipyridine ligand The ECL of these complexesin the presence of co-reactant TPrA or DBAE in aqueous buffer were studied.

The final AR films possess closed pore structure and hydrophobic/oleophobic surface that effectively prevents contaminant from getting into pores in film,therefore environment stability has been enhanced. The films exhibited excellent transmittance high as 99.98%on quartz glass substrate. The structure of ordered mesoporous films can be obtained by using synchrotron radiation at BSRF. When F127/Si molar ratio is 0...

Schematic illustrating the lamellae thickening induced by crystal transition in poly(butylene succinate).The stretching is horizontal. The reversible lamellar thickening was shown to mainly stem from by the reversible crystal transition:the repeating length in chain direction in theβcrystal is 9% longer than that inαform due to the conformation change. The crystal transition of PBS is expected to be a relatively...

Polymer crystallization is one of the most challenging topics in polymer physics. At present, there still lacks of clear understanding in the polymer crystallization, especially in the induction of crystallization of a polymer material.. Poly(ε-caprolactone) (PCL) is the ideal model to study polymer crystallization due to its particular properties. A team from School of Materials Science and Engineering of TianJi...

Hierarchical structured porous materials, which combine nanoparticles’ high chemical activity and microscale structures’ physical stability, are appealing materials as adsorbents in water treatment, energy storage and catalyst applications. However, it’s difficult to make clear the assembled structure through real time three dimensional imaging. A team from Key Laboratory for Molecular Nanostructures and Nanote...
