In this study, a nonchemical means of encoding the identity of each compound was used. The original polymer-bound reagent was placed in a porous microreactor equipped with a radio-frequency device that can be used for identification.168 The porous micro-... [Pg.907]

In the numerical model calibration phase, the unknown parameters are those contained in Fick s law and in the Butler-Volmer equation, i.e. the diffusion coefficients representing the porous micro-structural characteristics (e and r), and the electrochemical kinetics parameter (A and Ea). It should be noted that the calibration pro-... [Pg.103]

The general Theory of Porous Media (TPM) is a macroscopic continuum theory which is based on the theory of mixtures extended by the concept of volume fractions. In this theory neither the local porous micro structure nor the actual geometrical distributions of all the constituents have to be known. The TPM is a homogenized model, i.e. all geometrical and physical quantities can be seen as statistical averages of the real quantities (Bowen 1980 Ehlers 2002). [Pg.146]

The interactions between the processes and the environment can be particularly complex and have a marked influence on the characteristics of the limestone [2.3, 2.4]. Some limestones (e.g soft chalk) have not been fully compacted, are highly porous, micro-crystalline and contain well-defined fossils. Others (e.g. marble) have been completely metamorphosed, have very low porosities, are highly crystalline and contain no discernable fossils. [Pg.12]

We have summarised methods for the synthesis of ordered porous (micro, meso and macro) crystalline transition metal oxides. Crystalline transition metal oxides have unique redox, magnetic and electronic properties due to an incomplete d subshell. Properties such as size selectivity, facile and homogeneous access of reactants to the surface and photonic properties are added by introduction of ordered pores. The design and syntheses of ordered porous crystalline transition metal oxides remain areas of intensive research. [Pg.209]

MOX is a technique that was developed in the Madiran region of southern France in the 1980s and was commercially released in 19% (Cano-Lopez et al., 2006). Its principle is the continuous delivery of a small metered amount of oxygen into a wine by means of micro-bubbling using a porous micro-diffuser. [Pg.186]

No convincing conclusion has been reached as to the biodegradation mechanisms of bioactive ceramics. Many researchers have reported different results, as described above. These discrepancies are considered to be caused by the fact that materials used for the experiments were different, and that experimental methods and analytical methods were also different. Therefore, when these reported results are compared, it is important to consider the characteristics of the material used (chemical compositions, impurity, crystallinity, dense or porous, micro- or macro-porous, porosity), experimental methods used in vivo or in vitro, animal species, implanted duration, implanted sites, load bearing or not), and analytical methods used (radiographic, optical microscopic, electron microscopic). Futhermore, a good understanding of the characteristics of the materials to be used becomes important when bioactive ceramics are used clinically. [Pg.417]

In order to achieve appreciable macroscopic current densities while maintaining low local microscopic charge and particle flux densities, many battery electrodes that are used in conjunction with liquid electrolytes are produced with porous micro-structures containing very flne particles of the solid reactant materials. This porous structure of high reactant surface area is permeated with the electrolyte. [Pg.423]
