nuclear platen.

Brit.

/ˌnjuːklɪə ˈpleɪt/, U.S.

/ˌn(j)ukliər ˈpleɪt/

Origin: Formed within English, by compounding. Etymons: nuclear adj., plate n.

Etymology: < nuclear adj. + plate n. In sense 1 after German Kernplatte (E. A. Strasburger Über Zellbildung u. Zelltheilung (1876) 214; compare quot. 1880 at sense 1).

1. Cell Biology. = metaphase plate n. at metaphase n. and adj. Compounds. Now rare.

ΚΠ

1880 Amer. Naturalist 14 102 The fibres are all thickened in the middle at the same level; these thickenings produce the appearance of a distinct plate or disk in the middle (Strassburger's [sic] Kernplatte). It will be convenient to adhere to the term nuclear plate to designate these thickenings.

1925 Science 3 July 15/2 I found that in there are also chromosomes with satellites—one pair of such chromosomes in each diploid nuclear plate of each species.

1961 Amer. Jrnl. Bot. 48 570/2 The variation of individual chromosomes appearing in a nuclear plate was less in the species with 2n=16 or 32 than in the species with 2n=40.

2. A photographic plate covered with a nuclear emulsion.

ΚΠ

1949 Science 29 Apr. 438/2 The emergent beam of 335-MeV X-rays passes through a stack of nuclear plates (Ilford F-3), or through a slab of matter in the vicinity of such plates; then meson tracks in the emulsion are sought by microscopic examination.

1953 Proc. Royal Soc. A. 220 433 Whereas normal plates are fixed in about 3 min, the thickest of the nuclear plates require 2 to 3 weeks.

1991 Philos. Trans. (Royal Soc.) A. 337 512 (caption) Ilford nuclear plates type L4, exposures ca. 100 mA minutes electron beam current.
