A catalytic reaction over a silver catalyst performed in an unregarded temperature region(473-873 K) with a long catalytic lifetime for the production of methyl
The title compound (H3NCH2CH2NH3)4[(VO)6(B10O22)2](H3O)7 1 has been synthe- sized by the hydrothermal method and determined by X-ray crystallography.Crystallogr
A series of acrylic-based superabsorbent resins were synthesized by inverse suspension polymerization, using potassium persulfate as the initiator, N, N′-methy
The microstructures of electroformed copper liners of shaped charges that had undergone high-strain-rate deformation were observed by optical microscopy (OM) an
A new upconversion luminescence agent, 40CdF2·60BaF2·0.8Er2O3, was synthesized and its fluorescent spectra were determined. This upconversion luminescence age
With the help of the method of separation of variables and the Debye-Hüchel approximation, the Poisson-Boltzmann equation that describes the distribution of th
Two new saponins named davuricoside H and davuricoside K were isolated from the whole plant of Lysimachia davurica. The structures of davuricoside H and davuric
The tetrahedral borate ion can crosslink with polymer guar gum in aqueous solutions. If the concentration of guar gum is less than 0.045 g/dL, the intramolecula
A series of novel p(N-isopropylacrylamide) (PNIPAM) hydrogels were synthesized by radical copolymerization of N-isopropylacrylamide (NIPAM) and 3-methacryloxypr
