Excellent reference to gain an enhanced understanding of the fundamentals of the dynamics of adsorption phenomena at liquid interfaces. An in-depth theoretical description of methods to determine dynamic interfacial tensions is included in the book. 

The approach to time resolution of very fast processes described above has been used to study a variety of gas phase chemical reactions stimulated by pulses of either photons or electrons (37) While similar studies have not yet been performed for processes occurring at solid surfaces, it should be feasible to do so. Thus, for example, the dynamics of adsorption and reaction at a single crystal surface, could be studied using a chopped molecular beam as the source of reactants. Alternatively, a pulsed photon beam could be used to repeatedly stimulate a reaction between adsorbed species. 

The particle size of many synthetic zeolites is too small for most applications and therefore they must be formed into polycrystalline aggregates (e.g. by pelletization). Binders are often added to improve the aggregate strength and durability. It must be kept in mind that these or other changes in the particle or aggregate morphology may significantly affect the equilibria or dynamics of adsorption.

An important goal of investigations of the fundamental nature of catalysis is to provide a detailed analysis and characterization of the active surface sites and their role in the dynamics of adsorption and catalysis at the molecular level, whether induced by thermal energy (catalysis) and/or by photonic energy (photocatalysis). ...

Some key adsorbates and reaction intermediates relevant to fuel-cell anodes are H2 as the fuel, CO and CO2 as poisons in hydrogen reformate feeds, and water as a co-adsorbate and potential oxidant. In the case of the cathode, oxygen is clearly the most important reactant. In the case of a number of these molecules, such as H2, O2, and H2O, not only is the molecular adsorption important on platinum (or promoted platinum catalysts), but the dissociative adsorption of the molecules is important as well. With this in mind, some details concerning the dynamics of adsorption of these molecules, the associated dissociation barriers, molecular degrees of freedom, and energy partition are important to the overall catalytic processes. In addition to the... 

Theoretical studies of the properties of the individual components of nanocat-alytic systems (including metal nanoclusters, finite or extended supporting substrates, and molecular reactants and products), and of their assemblies (that is, a metal cluster anchored to the surface of a solid support material with molecular reactants adsorbed on either the cluster, the support surface, or both), employ an arsenal of diverse theoretical methodologies and techniques for a recent perspective article about computations in materials science and condensed matter studies [254], These theoretical tools include quantum mechanical electronic structure calculations coupled with structural optimizations (that is, determination of equilibrium, ground state nuclear configurations), searches for reaction pathways and microscopic reaction mechanisms, ab initio investigations of the dynamics of adsorption and reactive processes, statistical mechanical techniques (quantum, semiclassical, and classical) for determination of reaction rates, and evaluation of probabilities for reactive encounters between adsorbed reactants using kinetic equation for multiparticle adsorption, surface diffusion, and collisions between mobile adsorbed species, as well as explorations of spatiotemporal distributions of reactants and products. 

The results revealed a significant effect of surface-active and nonsurface active polysaccharides on the properties of adsorbed protein films at the air-water interface. To explain the observed effects on the dynamics of adsorption, the rates of diffusion and rearrangement and the surface dilatational modulus were taken into accoimt (i) the competitive adsorption, (ii) the complexation, and (iii) the existence of a limited thermodynamic compatibility between protein and polysaccharide at the air-water interface and in the aqueous bulk phase. 

The ability of polymeric materials to act at interfaces depends on the manner in which they respond to mechanical stress through their surface viscoelasticity (Gau et al., 1993). In addition, the dynamics of adsorption provides information concerning the processes that occur during surface adsorption.
