摘要:

The processcs occurring in electrolysis are described in an elementary way. The fundamental reasons for Faraday's laws are emphasized. Reversible e.m.f.'s and the conventions for writing them are summarized. The mechanism of ionic conduction and of electrode reactions is outlined.

摘要:

Electrical conduction in ultra-thin metal films is examined and the part played by an anomalous quantum mechanical tunnelling process is investigated. The process varies greatly with temperature, because the discrete metal particles forming the film are very small. The work required to remove a charge from such a particle being an inverse function of the particle size.

摘要:

A quantum fluid is one in which energy quantization has a marked effect on behaviour. Sometimes the effect can be dramatic, as with superfluid helium and with the electron gas in superconducting metals. In this article a simple criterion for distinguishing quantum fluids is obtained, and this is followed by a brief outline of the properties of perfect quantum gases. These ideas are then used as a unifying framework, within which some properties of real quantum fluids sre described and analysed. The approach to the subject is descriptive and physical, with very little dependence on mathematical argument.

摘要:

The changes which its own speed causes in the properties of air in the neighbourhood of a very high-speed aircraft can alter the aerodynamics of tho flow around the vehicle. This paper outlines the nature of these changes in air properties, mentions the techniques by which they can be studied in the laboratory, and also indicates their significance for flight at very high speeds.

摘要:

A novel method for doping semiconductors is ion implantation where impurities are injected in the form of high-energy ions. The range of these ions is well defined and is a function of ion energy and mass, the nature of the crystel and its orientation to the beam. In addition to its application to semiconductor device manufacture, ion implantation involves a good deal of interesting physics over a wide field, and in order to include the important aspect the article hes been divided into two parts.
