Both the spherical and the chromatic aberration of electron microscope objectives may, in principle, be corrected with the aid of a uniform retarding field acting as a mirror. Such an arrangement has the drawback of requiring a conducting film in the ray path and the insertion of the specimen in a region of high field…

Summary The theory of Molt ( 1940, 1947) for the oxidation of metals at low temperatures has been discussed and extended to oxides, such as Cu20, for which the metal diffuses through the oxide by the mechanism of vacant lattice points. It is also proved that the logarithmic law will be valid down to very low temperatu…
A phase equilibrium diagram of the system BaO-B20 3 has been constructed fr om data obtained essentiall y by the quenching method. Four congruently m elting compounds were identifi ed: BaOAB20 3, melting at 879 5 C; BaO.2B20 3, melting at 900 5 C; BaO.B20 3, melting at 1,095 5 C; and 3BaO.B20 3, melting at 1,383 5 C .…

Abstract An apparatus has been constructed which enables one to follow continuously the formation of monomer during degradation in vacuum. Experimental results are presented on the degradation of fractionated and unfractionated polystyrene over a range of temperatures from 340–400°C. in vacuum. A mechanism has been pr…
It is shown that in close packing of spheres, two types of interstice exist, bounded by six and by four convex spherical surfaces. These are termed ``square'' and ``triangular.'' They are connected by a continuous labyrinth through which a ball not exceeding (2/√3−1)r in radius can be threaded. In both cubic and hexag…
Formulas are derived for the calculation of stress in electrodeposits from the curvature developed in a plated strip. All the formulas are derived from the fundamentals of the theory of elasticity and the relationships among the various formulas are showll. Simplifi ed formulas are derived and their limits of applicab…
