The nucleation and initial stage of Pd2Si crystals on Si(111) surface is studied in situ using an Ultra-High Vacuum (UHV) Transmission Electron Microscope (TEM). A modified JEOL 200CX TEM is used for the study. The Si(111) sample is prepared by chemical thinning and is cleaned inside the UHV chamber with base pressure of 1x10−9 τ. A Pd film of 20 Å thick is deposited on to the Si(111) sample in situ using a built-in mini evaporator. This room temperature deposited Pd film is thermally annealed subsequently to form Pd2Si crystals. Surface sensitive dark field imaging is used for the study to reveal the effect of surface and interface steps.The initial growth of the Pd2Si has three stages: nucleation, growth of the nuclei and coalescence of the nuclei. Our experiments shows that the nucleation of the Pd2Si crystal occurs randomly and almost instantaneously on the terraces upon thermal annealing or electron irradiation.

SummaryA modification of the thromboplastin screening test of Hicks and Pitney is described, in which the effect of surface contact on the test plasma is controlled by the addition of a suspension of kaolin to the incubation mixture before recalcification.Comparative studies show the modified test to give more reproducible results than the standard method.

This article will examine the ethical and directorial challenges faced by the documentary filmmaker when collaborating with a central subject who lives with a potentially fatal genetic condition, whilst pursuing a career as a professional dominatrix. What modes of representation and collaboration are open to the director, when artificial boundaries and television genre categorisations such as ‘the science documentary’, ‘the biography’ and the fetish or ‘porno film’ seem limiting? Jabe Babe – A Heightened Life ( Merewether 2005 ) seeks to collapse and merge these conventionally distinct practices by developing a hybrid mode of representation, provoking questions about society's desire for sexual, visual, and genetic conformity.
