Hess, Walter

The writer is greatly indebted to C. S. Smith, C. S. Barrett, and E. A. Gulbransen for many fruitful discussions pertinent to surface studies pursued over an extended period. Much helpful assistance in the preparation and characterization of sample surfaces from the viewpoint of surface structure was provided at one time or another by Joseph Cerny, Walter Bergmann, Donald Clifton, Kaye Ikeuye, and James Hess. Without their assistance the tedious assignment involved in the meticulous preparation of sample surfaces could not have been achieved. The useful collaboration with L. P. Schulz on the characterization of metal surfaces by electron microscopy and electron diffraction techniques was an essential part of the surface studies. Assistance in the design and construction of techniques for the controlled evaporation of metals was provided by H. E. Shaw.

In view of the long history of research efforts on filled rubbers, it is not surprising that the initial works on filled polymer blends appeared in publications authored by rubber compounders and carbon black vendors [17, 18]. For instance, Walters and Keyte [17] observed that the compound ingredients, such as CB and zinc oxide, were not homogenously dispersed in rubber blends. Hess et al. [18] also reported a series of fundamental observations. First, they observed that filler particles tend to remain in the lower viscosity phase, in the absence of significant filler-matrix interactions. However, in the presence of strong polar-polar interactions between the filler particles and one of the phases, the particles were found to be selectively dispersed in the more polar phase and the viscosity became less important. More recently. Portal et al. [19] also presented similar observations about selective localization of CB particles in the natural rubber (NR) phase in NR/ polybutadiene blends. 

The deficiency disease described as scurvy has been known for a very long time. There are even records which date back to the time of the Crusades (see the accounts by De Joinville, in 1250, of the disease which beset the crusading armies of Louis IX before Cairo, published in Menard s 1617 edition of De Joinville s writings see also Angelenus, 1604 Kra-mer,2i2 1720 Walter,1748 Lind, 1753 Linton i 1858 Smart, 1888). All these authors described macroscopic changes in tissues and failure of wounds and fractures to heal in scurvy. The first comprehensive account of tissue changes in scurvy were given by Hess in 1920. 

Considerable investigative effort has been directed to the role of metabolite ratios and multiple metabolites in enzymic control. The complex nature of such control is exemplified by studies of oscillatory responses in the glycolytic pathway in both intact yeast cells and bovine heart cytosol. This subject has been considered by Higgins (1967), Hess and Boiteux (1971), Walter (1972, 1974), and Goldbeter and Caplan (1976) and is discussed in Chapter 8 of this volume.
