A primary characterization of perovskite-type oxides must include textural analysis and X-ray identification of the phase(s) present. For a more detailed characterization, structural analysis for establishing the lattice position of cations and surface analysis (by means of techniques such as XPS) for defining the surface concentration and oxidation states of cations are desirable. Consequently, information provided by these techniques will furnish the essential criteria for comparing the different preparation methods. For convenience, we will classify the methods used to date for the preparation of pure perovskite phases according to the scheme proposed by Courty and Marcilly (29) for the whole field of mixed oxides. Table I gives a survey of methods used as a function of the phenomena on which they are based.

Measurement of Film Thickness. An accurate definition of film thickness can only be given if the coating has even upper and lower surfaces and a defined density. In practice, neither the surface of the coating nor that of the substrate is even. Surface irregularities and density variations influence the results of each test method in a specific way. Results of different tests performed on the same sample may therefore differ substantially. Results of film thickness measurements therefore always have to be quoted together with details of the measurement method and instrument used [9.10], [9.11]. A survey of methods used to measure paint thickness is given in ISO 2808. 

The interfacial tension between the various polymer phases in the composite latex particles is of paramount importance in determining their final morphology. Other factors, such as the mode of monomer addition, the surface polarity of the polymer particles, initiator type, surfactant type, the presence or absence of crosslinking of one or more of the polymer phases, and the presence of chain transfer agents will also strongly influence the final particle structure. In addition, a survey of methods used to characterize the composite latex particles has been given.

Being recent research arrivals to the field ourselves, we wrote this chapter in a style that we hope will entice others to enter it as well. We begin with a brief overview of methods used to make capsules, making sure to reference other, more comprehensive sources in each case. We also survey the catalytic capsule field and capsules as drug-delivery vehicles, highlighting recent innovations in both areas. We hope this chapter will convince you that polymeric capsules are exciting materials with equally exciting applications. 

This survey of methods for obtaining configuration state functions has necessarily been brief, since the topic could easily occupy a course of its own. However, we have treated the methods in common use, and much additional material on second quantization techniques and matrix element evaluation will be covered elsewhere. 

Another system for measuring total cross sections, which has also been used for both positrons and electrons, is that developed by the Detroit group (see e.g. Stein, Kauppila and Roellig, 1974). Their apparatus and method embody many features not present in the widely used TOF technique. In addition, this group has made the most comprehensive survey of targets using both projectiles.

The proximate composition of peanut shells and seeds has already been compiled in the earlier review by J. C. Arthur, Jr. The proteins of peanuts were first investigated by Ritthausen in 1880. He extracted the proteins from oil-free peanut cake with sodium chloride and weakly basic solutions and precipitated them by acidification. He considered that the protein thus precipitated was homogeneous but later, Johns and Jones (1916) separated two proteins, arachin and conarachin, by ammonium sulfate fractionation. Afterward, several workers isolated peanut proteins, using different methods, and a survey of methods for separating individual globulins was published by Vanitraub and Shutov (1968). 

A broad overview of traditional methods and recent developments in experimental positron spectroscopy is presented. A discussion of the generation and detection of positrons and their annihilation radiation is followed by a survey of techniques used for positron lifetime measurement, Doppler broadening spectroscopy and angular correlation of annihilation radiation, and the opportunities presented by combining these methods (e.g. in age-momentum correlation) and/or extending their capabilities by the use of monoenergetic positron beams. Novel spectroscopic and microscopic techniques using positron beams are also described. 

Applications of photophysics in biology and medicine are very extensive and only a few topics can be mentioned in this review. A survey of the use of lanthanide ions as luminescent probes of biomolecular structure and a general account of long distance electron transfer in proteins and model systems are very helpful. The methods applicable to the synthesis and activation of a number of photoactivable fluoroprobes have been described and photoactivation yields measured . 

Because carbon black is the preferred support material for electrocatalysts, the methods of preparation of (bi)metallic nanoparticles are somewhat more restricted than with the oxide supports widely used in gas-phase heterogeneous catalysis. A further requirement imposed by the reduced mass-transport rates of the reactant molecules in the liquid phase versus the gas phase is that the metal loadings on the carbon support must be very high, e.g., at least lOwt.% versus 0.1-1 wt.% typically used in gas-phase catalysts. The relatively inert character of the carbon black surface plus the high metal loading means that widely practiced methods such as ion exchange [9] are not effective. The preferred methods are based on preparation of colloidal precursors, which are adsorbed onto the carbon black surface and then thermally decomposed or hydrogen-reduced to the (bi)metallic state. This method was pioneered by Petrow and Allen [10], and in the period from about 1970-1995 various colloidal methods are described essentially only in the patent literature. A useful survey of methods described in this literature can be found in the review by Stonehart [11]. Since about 1995, there has been more disclosure of colloidal methods in research journals, such as the papers by Boennemann and co-workers [12]. 

The scope of this chapter will be on these recent developments of the last three years, 1971 to 1973. We restrict ourselves to the interaction of neutral partners, with no restriction to the energy or state of the species. The article starts with a brief review of basic scattering laws and experimental techniques used in the experiments (Section II). Then the theory of elastic scattering is reviewed, the different cross section features are summarized and their sensitivity to the potential is discussed. Perturbations of these results caused from anisotropic potentials, inelasticities or potential crossings are described (Section 111). The next Section IV contains a survey of methods of how to determine the potential from the data. The emphasis will be on the inversion procedures. Finally, the results are summarized in Section V where, besides the atom-atom interactions in the ground states, new results for metastable species and molecules are included. 

This small survey of the uses of fluorination in selected substrates illustrates clearly the potential selective fluorination has as a tool to modify the reactivity and biological activity of those substances. Better and more effective understanding of chemistry of selectively fluorinated materials must necessarily await further evolution of not only synthetic methods but also of the underpinning chemical theory. Some latest advances in theory, synthetic methods and applications are chronicled in this volume on the subsequent pages. 

Until recently, N-sulfonyl imines had found only limited and sporadic use in organic synthesis. During the past decade, however, it has become increasingly clear that these species are valuable synthons and are capable of undergoing many unique transformations. A comprehensive review of the chemistry of these compounds is presented here with particular emphasis on their applications in stereoselective processes. Methods for preparing N -sulfonyl imines are outlined, along with a survey of their uses in a wide range of addition, pericyclic and cycloaddition reactions. 

The next step in the calculation is to determine the actual quality in the region beyond the bubble detachment. There have been a number of attempts to predict this from mechanistic models in which the rates of evaporation near the wall and condensation in the core of the flow are estimated and the quality is evaluated surveys of early versions of such models are given by Mayinger [240] and Lahey and Moody [241]. A more recent example of such an approach is that of Zeitoun and Shoukri [242], A simpler class of methods uses a profile fit these methods are exemplified by that of Levy [243], who relates the actual quality xa to the local equilibrium quality x (calculated from Eq. 15.208) and x(Zd) (calculated from Eq. 15.213 or 15.214) as follows ...
