The Olenekian Stage of the Lower Triassic is named from the Boreal Realm, but the stage has never been properly defined, nor has it been applied in the low-lati
New electron donors with hydroxyl groups were synthesized and characterized spectroscopically.Their redox potentials were determined with cyclic voltammetry, an
A complete potential energy surface for the CHClFOH system was calculated at the G3(MP2) level.The calculations reveal that the four-center 1,2-HX (X=F, Cl) eli
The UV-Vis spectra of THPPH2 in CTAB micelles at pH7.2 and pH11.0 were analyzed to study the effect of micellar environments on the aggregation behaviors of thi
A novel polymeric complex [La(bipyN2O2)(TFA)3]n(TFA= trifluoroacetylacetone) was prepared.The X-ray structure analysis revealed that the complex has an infinite
A new flavonoid, namely pinnatifine Ⅰ (1), was isolated from the leaves of Crataegus pinnatifida Bge.var.major N.E.Br..Its structure was elucidated by spectros
A combined EDTA-citrate complexing method was developed for the easy preparation of mixed oxygen-ionic and electronic conducting dense ceramic membrane for oxyg
The phase transition of two kinds of solvent-induced crystalline syndiotactic polystyrene (sPS) , γ-sPS and δe-sPS, has been studied via WAXD and DSC.γ-sPS t
