  • LAMINATED RESIN FILM, CURRENT COLLECTOR, AND SECONDARY BATTERY
    Publication number: 20240128463
    Abstract: A laminated resin film includes: a resin layer; and a Cu film provided on one surface or both surfaces of the resin layer, in which in the Cu film, a peak intensity y of a (200) plane is 2 to 30 when a peak intensity of a (111) plane in X-ray diffraction measurement is set to 100, and Expression (1) is satisfied. y?2.5×?7.5??Expression (1) (in Expression (1), y is the peak intensity of the (200) plane when the peak intensity of the (111) plane in the X-ray diffraction measurement is set to 100, and x is a peak intensity of a (220) plane when the peak intensity of the (111) plane in the X-ray diffraction measurement is set to 100.

  • Radioisotope iodine-labeled 1.alpha. (or 24R), 25-dihydroxy vitamin D.sub.3
    Patent number: 5214170
    Abstract: A novel 1.alpha. (or 24R), 25-dihydroxy vitamin D.sub.3 amino acid derivative of the formula ##STR1## wherein R.sub.1 is OH or --O--CO--A--NH.sub.2, and R.sub.2 and R.sub.3 are each selected from the group consisting of hydrogen, OH and --O--CO--A--NH.sub.2 ; wherein one of R.sub.2 and R.sub.3 is hydrogen, one of R.sub., R.sub.2 and R.sub.3 is OH, and one of R.sub.1, R.sub.2 and R.sub.3 is --O--CO--A--NH.sub.2 ; and wherein A is C.sub.1-10 alkylene, is produced by removing a protective group for the amino group, e.g. 9-fluorenylmethyloxycarbonyl, in the presence of a base in an inert solvent. A radioisotope iodine-labeled residue is then attached to the amino group to produce a derivative useful in the assay of 1.alpha. (or 24R), 25-dihydroxy vitamin D.sub.3 in a specimen.
