Connectivity effects

Usually, a hysteresis loop appears because of different adsorption and desorption mechanisms and network or connectivity effects. 

To our knowledge no (semi-)metal adducts of stable carbenes are known for groups 15 and 16 except 41-43. However, the oxidation of a 2-telluroimida-zoline with iodine provides an interesting point of connection, effectively providing aTel2adductofaNHC. ... 

Many porous adsorbents give Type H2 hysteresis loop, but in such systems PSD or pore shape is not well-defined. Indeed, the H2 loop is especially difficult to interpret. In the past it was considered to be a result of the presence of the pores with narrow necks and wide bodies (ink-bottle pores), but it is now recognized that this provides an over-simplified picture and the pore connectivity effects must be taken into account.79... 

Thus, the total resistance of NCM is represented as the sum of the series-connected effective resistances, which corresponds to different phases in NCM ... 

All the studies presented here omit connectivity effects due to the micropore network. 

In another study,BorsaU and Benmouna discussed the static and dynamic scattering properties of ring diblock copolymers in solution [289]. They focused their attention on the semi-dilute region and the case of compositionally symmetric ring diblock copolymers. Differences in the scattering profiles were predicted, the main reason being the presence of connection between the two ends of the chain in the case of ring copolymers. Due to this connectivity effect, different con-... 

Fig. 11. Classification of adsorption-desorption hysteresis loops. HI are typical for materials containing agglomerates and for materials with cylindrical pore geometry and a high degree of pore size uniformity. The type H2 is characteristic of materials with relatively uniform channel-like pores with the pore connectivity effects. H3 type is attributed to aggregates (loose assemblages) of platelike particles forming slitlike pores. The type H4 loop is proposed to be attributed to large mesopores embedded in a matrix with pores of much smaller size. Reprinted with permission from [76].

Some applications nonrelated to the properties of the nanoporous materials but to their porous structures are their use as filtration membranes, battery separators (hindering the diffusion of ions in the narrow channels), and catalyst supports (due to their high surface area) as well as gas capture and storage or light harvesting [72]. However, the common factor of all of these applications is the requirement of an open nanoporous structure not only inside the sample but also connected to the exterior of the sample. However, the CO2 foaming process from nanostructured polymers still has not allowed obtaining nanoporous samples with all of these features. Pinto et al. [102] proposed that 25/75 PMMA/MAM nanoporous foams present appropriate inner porous structures for these kinds of applications (bicontinuous nanoporous structures with tunable pore size), but further studies are required to connect effectively this inner porous structure with the exterior of the sample. 

The hysteresis loop can be identified with an H2 type behavior [79], characteristic of pore connectivity effects. In this case the desorption branch occiu-s at low relative pressure, which is related to the uniform channel-like structure. 

The exponential part in Eq. (59) arises from the sped chain conformational energetics whereas the front term reflects the diain connectivity effect and frictional drag due to environment. The role of the latter becomes predominantly important in intermediate regime dynamics. 

We have reviewed here the simplest, isothermal version of CDLG models for two-phase fluid dynamics on the microscopic scale. Applications of these models for studying interfacial dynamics in liquid-vapor and liquid-liquid systems in microcapillaries were discussed. The main advantage of our approach is that it models the exphcit dependence of the interfadal structure and dynamics on molecular interactions, including surfactant effects. However, an off-lattice model of microscopic MF dynamics may be required for incorporating viscoelastic and chain-connectivity effects in complex fluids. Isothermal CDLG MF dynamics is based on the same local conservation laws for species and momenta that serve as a foundation for mechanics, hydrodynamics and irreversible thermodynamics. As in hydrodynamics and irreversible thermodynamics, the isothermal version of CDLG model ean be... 

Along with the mathematical models for the structures, neuro based training algorithms should be supplemented to consider the uncertainty in modeling arising out of the flexibility at connections, effect of nonlinearity (material and geometric), etc. Thereafter the controller should be designed on these hybrid models. 

In the early days, IP was directed mostly on ore mineral exploration. Later, pore space properties and connected effects became more interesting. Today, frequency-dependent complex resistivity measurements are generally directed on problems of pore space characterization and description of fluid-mineral interactions. Measurements are sensitive to physico-chemical mineral-water-interaction at the grain surfaces. In comparison to conventional geoelectrics, a complex electrical measurement can also provide - besides conductivity -information on the electrical capacity and the relaxation process in the frequency range below some kHz (Bomer, 2006).
