A method for measuring the width of domain walls by Lorentz electron microscopy is presented and applied to the case of a single−crystal iron film. The method consists of measuring the domain wall image width at a number of defocusing distances and

The composition and structure of oxide films formed on electropolished single crystals of copper were studied for eight different crystal faces, using X-ray diffraction techniques. Particular care was taken to assure the best possible surfaces as con

LEED and HEED techniques have been used to study the interaction of oxygen with single crystal surfaces of copper. Special structures due to the adsorption of oxygen are reported for the (100), (110) and (111) surfaces as observed by LEED. The same s

The growth and structure of thin electrodeposits of several metals on single-crystal substrates have been studied by means of electron diffraction and electron microscopy. Deposits of copper on nickel, nickel on copper, and gold on copper show a high

Bicrystal metal films were prepared by electrodeposition of nickel on evaporated, single‐crystal copper films. Electron microscopic examination of the bicrystal films revealed interfacial dislocations which aid in reducing the misfit strain between

Estrogen has a marked effect on the expression of vitellogenin, the egg yolk precursor protein in the liver of egg-laying vertebrates. cDNA clones specific for trout vitellogenin mRNA have been used to study the expression of the vitellogenin genes i

Poly (A)+ RNA from the prostates of both intact and castrated rats was translated in a message-dependent reticulocyte lysate, and the translation products were electrophoresed on SDS/polyacrylamide gels. Fluorography of these gels showed the expected

The structure of thin copper electrodeposits on single crystal nickel substrates has been previously studied in this laboratory. We thought it would be desirable to prepare similar bi-crystal films by the evaporation of copper onto nickel so that a c
