Without any doubt, the zeolite framework porous characteristics (micropores sizes and topology) largely govern the zeolite properties and their industrial applications. Nevertheless for some zeolite uses, as for instance, host materials for confined phases, the zeolite inner surface characteristics should be precised to understand their influence on such low dimensionality sorbed systems. In that paper, we present illustrative examples of zeolite inner surface influence on confined methane phases. Our investigation extends from relatively complex zeolite inner surface types (as for MOR structural types) to the model inner surface ones (well illustrated by the AFI zeolite type). Sorption isotherm measurements associated with neutron diffraction experiments are used in the present study. 

Qads.(max) = 5.7 molecules by unit cell). Generally speaking, Qacis.(max) is closely related to the molecular size, as it is observed for the other molecular species. Secondly, as shown on Figure 5, sorption isotherm sub-step observation could be another signature of zeolite inner surface influence. Such isotherm sub-step reflects a phase transition existence between a fluid phase and a solid phase stabilized by the inner surface sorption sites.

A gas phase reaction, A = B, is carried out under conditions where both surface reaction and diffusion to the external surface influence the overall rate of conversion. The feed rate is 200 Ibmol/hr of pure A, the pressure is 2 atm and 50% conversion is required. 

The configuration of near sohd phase water can be altered in close proximity to the phyUosilicate. The siloxane surface influences the character of the water due to the nature of their charge distribution and the complexes formed between the cation and the surface functional groups. Both the type of charge and degree of charge localization, as well the valence and size of the complexed cations, confiol the characteristics of the water molecules near the surface.

Physical and numerical models are created describing the d3mamics of turbulent combustion in heterogeneous mixtures of gas with polydispersed particles. The models take into account the thermal destruction of particles, chemistry in the gas phase, and heterogeneous oxidation on the surface influenced by both diffusive and kinetic factors. The models are validated against independent experiments and enable the determination of peculiarities of turbulent combustion of polydispersed mixtures.

Spectroscopic evidence for the transient formation of the trans-stilbene radical cation could be obtained when colloidal TiOj suspended in an acetonitrile solution containing trans-stilbene (a species which should also be exothermically oxidized by a TiO valence band hole) was excited with a laser pulse The observed transient was identical in spectroscopic features and in lifetime with an authentic sample of the stilbene cation radical generated in the same medium via pulse radiolytic techniques. That the surface influences the subsequent chemistry of this species can be seen in the distribution of products observed under steady state illumination, Eq. (4) 2 . ... 

An aircraft has three obvious advantages over a surface site. First, the aircraft can measure vertical and horizontal profiles of concentrations such measurements are not possible at the surface. However, because the typical aircraft travels horizontally much faster than it ascends or descends, it may be difficult to deconvolute vertical from horizontal variations. Second, the aircraft allows the investigator to choose the general type of air parcels to study rather than simply allowing sampling of whatever parcels are brought to a site (as on the surface). Third, the aircraft can measure concentrations free from the surface influences discussed in the preceding sections.
