Materials chemistry is now served by a whole range of journals, ranging from the venerable Journal of Solid-State Chemistry and Materials Researeh Bulletin (already mentioned) to Materials Chemistry and Physies (which, interestingly, now incorporates The International Journal of the Chinese Soeiety for Materials Seienee... which appears to be distinct from the Chinese MRS) and Journal of Materials Chemistry (published by the RSC in London) - also Chemistry of Materials, published by the ACS. In France, Annales de Chimie Seienee des Materiaux is an offshoot of a journal originally founded by Lavoisier in 1789 (shortly before he lost his head). Journal of Materials Synthesis and Proeessing is an interesting periodical with somewhat narrower focus. 

Electron interactions more complicated than those considered by London also result from the quantum mechanics, and in some cases provide explanations for previously anomalous molecular structures.

The final chapter, by Hounsell (London), also relates to an important aspect of glycoprotein structure, namely the structures and shapes, as determined by physicochemical methods, of oligosaccharide determinants of glycoproteins that are antigens and targets for binding of adhesion molecules.

Their results provided quantum-mechanical backing for the Lewis shared-electron-pair model for the chemical bond. As noted in two more landmark articles published by Pauling [60] and Slater [61] in 1931, the calculations of Heitler and London also suggested that the chemical bond will be strongest if the two atomic...

The charge on a droplet surface produces a repulsive barrier to coalescence into the London-van der Waals primary attractive minimum (see Section VI-4). If the droplet size is appropriate, a secondary minimum exists outside the repulsive barrier as illustrated by DLVO calculations shown in Fig. XIV-6 (see also Refs. 36-38). Here the influence of pH on the repulsive barrier between n-hexadecane drops is shown in Fig. XIV-6a, while the secondary minimum is enlarged in Fig. XIV-6b [39]. The inset to the figures contains t,. the coalescence time. Emulsion particles may flocculate into the secondary minimum without further coalescence. 

The appropriate quantum mechanical operator fomi of the phase has been the subject of numerous efforts. At present, one can only speak of the best approximate operator, and this also is the subject of debate. A personal historical account by Nieto of various operator definitions for the phase (and of its probability distribution) is in [27] and in companion articles, for example, [130-132] and others, that have appeared in Volume 48 of Physica Scripta T (1993), which is devoted to this subject. (For an introduction to the unitarity requirements placed on a phase operator, one can refer to [133]). In 1927, Dirac proposed a quantum mechanical operator tf), defined in terms of the creation and destruction operators [134], but London [135] showed that this is not Hermitean. (A further source is [136].) Another candidate, e is not unitary. 

A laboratory demonstration of this operation is far better than any written description. The tubes may be bought from many dealers e.g., A. Gallenkamp r Co. Ltd., Technico House, Christopher Street, London, EC2P 2ER, and Victoria House, Widnes, Lancs also The Scientific Glass- Blowing Co., 41 Upper Brook Street, Manchester 13), but students should learn to make their own c.apillary tubes.

I would like to credit especially the fundamental contributions of Ron Gillespie to strong acid (superacid) chemistry and also to recall his generous help while I was still working at the Dow Laboratories in Canada. 1 reestablished contact with him during this time.

Until surface contact, the force between molecules is always one of attraction, although this attraction has different origins in different systems. London forces, dipole-dipole attractions, acid-base interactions, and hydrogen bonds are some of the types of attraction we have in mind. In the foregoing list, London forces are universal and also the weakest of the attractions listed. The interactions increase in strength and also in specificity in the order listed.
