A formalism, thought to be a suitable basis for the theoretical treatment of photodesorption as the physical outcome of interaction between a photon and an adsorbed species, and a solid surface, has been outlined by Grimley [123] together with indications of the substantial obstacles to [Pg.333]

However, photoinduced change in the extent of ionisation of 0 (or 20 ) may occur, as in eqns. (17b) and (17c) without the accompaniment of photosorption, viz. [Pg.334]

Solonitsyn further envisaged that subsequent localisation of electrons set free in these photoinduced processes would tend to increase the extent of surface coverage by 02 through the process [Pg.335]

This reaction scheme was explicitly recognised [124] as differing basically from electronic models based on the photoinduced disturbance of collective-electron energy levels of the bulk adsorbent. [Pg.335]

Spectral dependence of the photoadsorption of oxygen on powdered samples of pure zinc oxide or sine oxide doped with lithium or aluminium has been studied by Zakharenko et al. [127] whose results provided [Pg.335]


The latest tw o-phase flow research and design studies have broadened the interpretation of some of the earlier flow patterns and refined some design accuracy for selected situations. The method presented here serves as a fundamental reference source for further studies. It is suggested that the designer compare several design concept results and interpret which best encompasses the design problem under consideration. Some of the latest references are included in the Reference Section. No one reference has a solution to all two-phase flow problems. [Pg.124]

A quantitative study of the azo coupling reactions of heterocyclic diazo compounds was made by Sawaguchi et al. (1971), who measured the coupling rates of seventeen heterocyclic diazonium ions with R-acid (2-naphthol-3,6-disulfonic acid) and compared them with those of the benzenediazonium ion with the same coupling component. All the heterocyclic diazonium ions investigated react faster with R-acid than does the benzenediazonium salt. More recently, Diener and Zollinger (1986) confirmed Sawaguchi s results and interpreted them in more detail. [Pg.309]

Equations) gives these equations in a common format because not all r-test procedures return tbe same number of degrees of freedom or the same r-value, the interpretations can slightly differ. For each of the four combinations of N] (=, 7 ) Nj and Vi (=, 7 ) V2 all equations that apply are used and the corresponding results and interpretations are displayed. [Pg.385]

This is important not only in field investigations. Even in laboratory experiments on the metabolism of xenobiotics, problems of association between the substrate and the microbial cells may occur. If this were not quantitatively evaluated or eliminated, the results and interpretation of such experiments would be seriously compromised. [Pg.210]

The most detailed NMR study of impurity band formation in a semiconductor in the intermediate regime involved 31P and 29 Si 7). line width and shift measurements at 8 T from 100-500 K for Si samples doped with P at levels between 4 x 1018 cm 3 and 8 x 1019 cm 3 [189], and an alternate simplified interpretation of these results in terms of an extended Korringa relation [185]. While the results and interpretation are too involved to discuss here, the important conclusion was that the conventional picture of P-doped Si at 300 K consisting of fully-ionized donors and carriers confined to extended conduction band states is inadequate. Instead, a complex of impurity bands survives in some form to doping levels as high as 1019 cm 3. A related example of an impurity NMR study of impurity bands is discussed in Sect. 3.8 for Ga-doped ZnO. [Pg.267]

It has since become increasingly clear that zwitterionic zirconates may be generated in many other reactions and may lead to unexpected and interesting chemical consequences, as suggested by the results and interpretations shown in Scheme 1.73. It should be noted that the empty orbital and electrophilicity of Zr must lead to zwitterionic species containing zirconates and carbocationic centers. Further systematic investigations in this area appear to be desirable. [Pg.44]

Let us take 1978 as the starting point. Massoth [51] then published an extensive review of what was known about the structure of HDS catalysts. Characterization was essentially based on techniques such as X-ray diffraction, electron microscopy, photoelectron spectroscopy, electron spin resonance and magnetic methods. Massoth was rather unhappy with the state of affairs in 1978. He was struck by the ...diversity and apparent contradictions of results and interpretations... It almost seems as though everyone is working with a different catalyst . [Pg.267]

Model reaction tests focus on analyzing optimization value chain planning results and interpreting the impact of single model parameters on the overall results. [Pg.214]

The results and interpretations summarized in points 1-4 have been represented diagrammatically in Figure 13. This forms in a sense a concrete formulation of the speculations presented earlier (Havinga and Kronenberg, 1968). It makes clear that the quantum yields and the product composition are determined by a combination of... [Pg.262]

The order in which you present findings (in Results) and interpret findings (in Discussion) should be parallel. [Pg.167]

Let s begin with the excerpt on randomly methylated P-cyclodextrin (RAMEB)-enriched soils in chapter 4 (excerpt 4B). The authors use an iterative R D approach They state their first result (Rl), pertaining to clay-rich soils, and then immediately offer an interpretation (Dl) of that result. This is followed by a result and interpretation for clay-poor soils (R2D2) and a result and interpretation for medium-clay-content soils (R3D3). Thus, the result-discussion sequence is iterated three times. In each case, the discussion immediately follows the result hence, submove 1.1 (which reminds readers of the result) is not needed. [Pg.170]

R3D3 offers the results and interpretation for the water-sorption behavior of the medium-clay-content soil (S5). We include R3 below (slightly modified) ... [Pg.171]

Write a complete draft of your Discussion section. Begin with an outline of your results and interpretations, and then convert the outline to full sentences. Sketch out any schemes (or figures) you plan to include, and draft the text that will accompany those schemes. End your draft with a paragraph that concludes your paper and suggests the broader applications of your work. [Pg.186]

INR - INR is based on the determination of an International Normalized Ratio that provides a common basis for PT results and interpretations of therapeutic ranges. For a discussion of the relationship between PT and INR in clinical practice, refer to Administration and Dosage. [Pg.142]

Overview), but also information on how to set-up experiments so that they produce results that can be interpreted and extrapolated (Part B Ozone Applied). The experimenter is provided with tools to improve his or her results and interpret results found in the literature. The required theoretical foundation is laid at the beginning of each chapter in Part B, compact and tailored to ozone, followed by practical aspects. References are made to important literature sources to help direct the reader wishing for more in-depth information. A discussion of applications combining ozone with other processes illustrates how the oxidizing potential of ozone can be utilized. [Pg.2]

This volume of the Advances in Chemical Physics is the second to be devoted entirely to studies of the excited states of molecules. Since the publication of the first volume, there has been continued expansion of the subject. The contributions in this volume, which cover a variety of topics, supplement the earlier articles and report the results and interpretations based upon later technology. Just as for the earlier volume it is hoped that this and succeeding volumes will supplement the rather broadly scattered literature and provide an introduction both for the interested student and the working scientist. [Pg.626]

Anyone who has had occasion to peruse the literature on these catalysts will be struck by the diversity and apparent contradictions of results and interpretations reported by different authors. This dismaying state of affairs may account for the tendency of workers to quote other workers results which support theirs but to ignore other data which disagree. It almost seems as though everyone is working on a different catalyst—and this may not be as farfetched as it seems. Much of the disparity in results may be due to differences in catalyst preparation, which has generally not been fully appreciated. [Pg.268]

Several types of reaction are involved in these systems, and the kinetics is far from clear in most cases. It therefore seems better to present in one place a brief summary of results and interpretations rather than dissecting out each type reaction for discussion in its appropriate section of this chapter. The kinetics of these reactions has been reviewed157 251. [Pg.167]

The fuel source is methane and a reformer is necessary. For this study, the reformer is externally heated such that it is not a heat load on the system. This allows one less physical feedback mechanism on the dynamic system, which will simplify the result and interpretation of the results. (For real application studies, the coupling is needed for peak efficiency reasons.)... [Pg.265]
