El empleo de isótopos permite estudiar perfectamente el desplazamiento de los materiales a lo largo del horno. en otros aspectos referentes a la influencia de diversos factores sobre el funcionamiento del horno y sobre el proceso de cocción, se llega a la misma conclusión que mediante los métodos clásicos de investiga…

Abstract Relations between the soluble fraction and the number of effective chains between crosslinks in a three‐dimensional network undergoing a scission reaction have been derived. Three limiting cases have been considered: (a) random scission in the chains, (b) scission in the chains directed by the crosslinks, and…

Properties of electrolyte-semiconductor barriers are described, with emphasis on germanium. The use of these barriers in localizing electrolytic etching is discussed. Other localization techniques are mentioned. Electrolytes for etching germanium and silicon are given.

Abstract The absorption spectra of fifty-two natural diamonds have been measured at 80 and 290°K. Type I diamonds are shown to have two kinds of absorption centres which are not detected in type II diamonds. Differences in the infra-red absorption spectra between type IIa and type IIb diamonds are reported. The classi…

An optical absorption band at 9\ensuremath{\mu} has been correlated with the oxygen content in silicon. Pulled silicon crystals were found to contain up to ${10}^{18}$ oxygen atoms per ${\mathrm{cm}}^{3}$ which seem to originate from the quartz crucible. The oxygen concentration in silicon crystals prepared by the flo…

Abstract An account is given of the deformation and fracture characteristics of single crystals of high-purity iron of various orientations when tested in tension at temperatures from 100 to ─253°C. At temperatures down to ─124°C, the crystals were fully ductile, giving chisel-edge fractures and 100% reduction in area…
