Where Pg is the pressure of vapor in equilibrium with the adsorbed film. The characteristic curve is now just PF In Pq/P versus x (or against [c.627]

The first term on the right is the common inverse cube law, the second is taken to be the empirically more important form for moderate film thickness (and also conforms to the polarization model, Section XVII-7C), and the last term allows for structural perturbation in the adsorbed film relative to bulk liquid adsorbate. In effect, the vapor pressure of a thin multilayer film is taken to be P and to relax toward P as the film thickens. The equation has been useful in relating adsorption isotherms to contact angle behavior (see Section X-7). Roy and Halsey [73] have used a similar equation earlier, Halsey [74] allowed for surface heterogeneity by assuming a distribution of Uq values in Eq. XVII-79. Dubinin s equation (Eq. XVII-75) has been mentioned another variant has been used by Bonnetain and co-workers [7S].  [c.629]

In the endeavor to deepen understanding of chemistry, many an experiment has been performed, and many data have been accumulated. Chapter 6, on databases, gives a vivid picture of the enormous amount of data that have been determined and made accessible. The task is then to derive knowledge from these data by inductive learning. In this context we have to define the terms, data, information, and knowledge, and we do so in a generally accepted manner.  [c.7]

This insulation does, in fact, seem to occur. It was remarked on in connection with Fig. XVII-21 and was very explicitly shown in some results of Dubinin and coworkers [139]. Nitrogen adsorption isotherms at -185°C were determined for a carbon black having various amounts of preadsoibed benzene. After only about 1.5 statistical monolayers of benzene, no further change took place in the nitrogen isotherm. A similar behavior was reported by Halsey and co-workers [140] for Ar and N2 adsorption on Ti02 having increasing amounts of preadsorbed water. In this case, a limiting isotherm was reached with about four statistical layers of water, the approach to the limiting form being approximately exponential. Interestingly, the final isotherm, in the case of  [c.654]

Adsorption isotherms in the micropore region may start off looking like one of the high BET c-value curves of Fig. XVII-10, but will then level off much like a Langmuir isotherm (Fig. XVII-3) as the pores fill and the surface area available for further adsorption greatly diminishes. The BET-type equation for adsorption limited to n layers (Eq. XVII-65) will sometimes fit this type of behavior. Currently, however, more use is made of the Dubinin-Raduschkevich or DR equation. Tliis is Eq. XVII-75, but now put in the form  [c.669]

Figrn c 5-31 gives an cxccrpt from the search results for the daphnia toxicity of atrazinc in the large environmental portal German Environmental Information Network, called GEIN. GEIN functions as a uni<]iie web interface to data collections of 70 suppliers of environmental information, mostly governmental authorities and other German public institutions. It offers access to more than 140 000 individual web pages and nine databases, and even to hidden (dynamic) web pages such as environmental data catalogs of German federal states and the German Government. For this search example, performed on October 21, 2002, the number of hits was 100, Not only German but also English and French hits are obtained in this search. Links to publications and databases arc given.  [c.275]

This means that the methods developed for the calculation of physicochemical effects can also be used to deepen our understanding of biochemical rcaaions. Clearly, electronic effects within the substrate molecule arc not the only ones determining its reactivity, The binding of the substrate to the enzyme is also influenced  [c.561]
