Pellets. Pellets are mainly prepared by four different methods powder layering, rotating fluidized bed, extrusion/spheronization, and the agglomeration method. The oldest one is the so-called. 

These relative surface excess parameters can be determined experimentally using different methods /)(w) can be determined by radiotracer studies, o-measurements, electroanalytical techniques (twin-electrode thin-layer, flow-through thin layer, rotating ring-disk experiments) etc., whereas q can be determined by charging curves, capacitance measurements etc. Isotherm conversion q-Fiiyf) is obtained by the corresponding Maxwell relations ... 

Even given Europa s orbital eccentricity e, the rotation might be synchronous if a non-spherically symmetric, frozen-in density distribution (like that of the Earth s Moon) were locked to the direction of Jupiter. Given that Europa is substantially heated by tidal friction, it may not be able to support such a frozen-in asymmetry. It is also conceivable that the silicate interior is locked to the direction of Jupiter by a mass asymmetry, while the ice crust, uncoupled from the silicate by an intervening liquid water layer, rotates non-synchronously due to the tidal torque. 

In the Sl phase, the molecules are perpendicular to layers and are arranged in a hexatic lattice within layers. This symmetry is the same as that of the Sb phase. Both of the Sl and Sb phases are optically uniaxial, their molecules within smectic layers rotate more freely around their long axes or rotate in groups simultaneously. In some of the literature, the Sb phase is called the hexatic B phase while the Sl phase is named the Sb phase or crystal B phase. The molecules within the Sq and Si phases are tilted with respect to the layers while the molecules of the Sl phase are aligned more or less perpendicularly to the layers. The stacking of molecules within the layer of the Sl, Sq and Sj phases is similar to those shown in Figure 1.7 as well. The crystallography classifications of these three liquid crystal phases are the same as those of the Sb, Sp and Si phases.

Note that the unit cell consisting of two layers rotates as a whole forming two geared helices of the same handedness. This type of rotation is controlled by molecular chirality inherent in all phases shown in Fig. 13.21...

Section 2 covers the DHF mode with a helical structure. The bookshelf structure, the Cl-uniform (CIU) orientation, and the C2-uniform (C2U) orientation are described in Sections 3, 4, and 5, respectively. Section 6 covers the stability of the molecular orientations in FLC devices exposed to shock. Weakness in this respect is one of the intrinsic problems of FLC displays. The layer rotation behaviour, an intrinsic behaviour of FLC displays, is described in Section 7. 

The layer-rotation phenomenon is one of the unique behaviours of FLC and AFLC devices. It is caused by the presence of spontaneous polarization. 

This layer-rotation phenomenon is clearly visible in FLC cells in which only one substrate has been rubbed and in which the FLC material has an lAC phase sequence. This layer rotation is also observed when FLC materials show the nematic phase and a single substrate is rubbed. This layer rotation is attributed to the helical structure of a material in the nematic phase [38]. When, on the other hand, the same aligning film is used under both substrates and the substrates...
