摘要： A method of making a superconducting structure includes depositing a metal alkoxide on a surface of a metal and hydrolyzing the metal alkoxide on the surface to form a pinhole-free film. The metal is a superconductor. The metal alkoxide may be a compound of formula (I): M4(OPrn)16  (I); where M is zirconium or hafnium, and the purity of the compound is at least 97% as measured by NMR spectroscopy.

摘要： An improved process for preparing anion exchange resins based on the use of a non-agitated plug-flow quench procedure followed by recycle of a portion of the recovered chloromethylation reaction fluids into subsequent chloromethylation reactions is disclosed. The combination of plug-flow hydration, providing highly concentrated recovered sulfuric acid, together with the recycle or reuse of the recovered concentrated sulfuric acid, allows for reduced raw material requirements during anion exchange resin manufacture and reduces the environmental impact of waste sulfuric acid processing.
