Alignment of layers

HOPG cylinders showed that intercalation starts close to the basal planes and proceeds thence to the central layers. Cylinders capped at both ends with glass caps and grease are not intercalated. The layer system is split into a number of discs at a rate that increases with the degree of alignment of layer planes. For non-heat-treated PG, the threshold pressure increases with the number of layer planes in the sample. Similar results confirming this mechanism have been obtained with metal halides (H13). A mechanism of intercalation based on these results has been discussed by Hooley (H22).

Figure 1 Non-local layer dependent conductivity for majority electrons for parallel alignment of the cobalt moments. The scattering rate is assumed to be high so that the electron lifetime is relatively short (4.8X10 sec).

Figure 3 Non-local layer dependent conductivity for one spin channel for antiparallel alignment of the cobalt moments. This spin channel is locally the majority in the cobalt on the left side of the sample.

Note that majority electrons that are accelerated by the electric field in one of the cobalt layers contribute to the current, not only in that layer (I = J) but in other layers as well, including the copper layers and the cobalt layers on the other side of the copper. On the other hand, minority electrons that are accelerated by a field in one of the cobalt layers contribute very little to the conductivity in the copper or in the cobalt on the other side of the copper. For anti-parallel alignment of the moments, electrons that are accelerated by the field in one cobalt layer contribute to the current in that layer and in the cobalt, but not in the other cobalt layer. The difference in the lolal current due to both channels between parallel and anti-parallel alignment is almost entirely non-local. It comes from those electrons that are accelerated by the applied electric field in one cobalt layer and propagate across the copper to the other cobalt layer where they contribute to the current. It is clear from Figures 1-4 that this process occurs primarily for majority electrons and for the case of parallel alignment. 

Figure 4 Giant Magnetoconductance. The change in the non-local layer dependent conductivity between parallel and anti-parallel alignment of the cobalt moments. For this case of strong scattering in both the cobalt and copper, contributions to the GMR come from electrons that are accelerated in one cobalt layer and contribute to the current in the other.

The third category, shown in Fig. 2d, results when all of the long molecules or microcrystallites are aligned along the fiber axis, but they aggregate with little lateral ordering. This assembly, called an oriented fiber, diffracts to produce a series of layer lines that are perpendicular to the fiber axis. The intensity is nonuni-... 

Next, we coated the heating plates with graphite from a number two pencil and smoothed it out with a Q-tip to make a release and contamination shield layer. The three layers (catalyst-PEM-catalyst) of the sandwich were then set on top of the lower heating plate. After carefully aligning the layers, so that the smaller catalyst disks were centered above and below the larger PEM disk, the upper heating plate was placed on top of the sandwich. At this time the heaters were off and the plates were at room temperature. 

The shift factor b, shows a large deviation from a simple density effect, it would be expected that the values would not vary far from unity [44], One possible explanation is an internal structure development occurring in PLANCs during measurement (shear process). The alignment of the silicate layers probably enables the PLFNC melts to withstand the shear force, thus leading to the increase in the absolute values of G (co) and G"(co). 

The crystal lattices of a series of ternary alkali metal-silver acetylenediide [M Ag(C=C)] (M1 = Li 161, Na, K 162, Rb, Cs 163) have been analyzed by Ruschewitz and co-workers using X-ray powder diffraction.209 Neutron powder diffraction experiments have also been performed on 161-163 for obtaining precise bond lengths. It has been found that for 161 and 162, the [Ag(C C)] chains were packed parallel to each other, whereas for 163, they were aligned in layers that were rotated by 90° with respect to each other (see Figure 51).
