Linear rows

Recently, it has become clear to the author that cyclodextrin is one of the promising hosts for macromolecular recognition, with the finding that the cylindrical channel formed when it is stacked in a linear row is able to accommodate one or more long-chain guests. Thus, he and his coworkers launched a series of experiments to explore the formation of inclusion complexes between... 

The identification of terminal complexes in the Gram-negative bacterium Acetobacter xylinum now appears to be in doubt. Previously, a single linear row of particles observed on the outer lipopolysaccharide membrane... 

Fig. 28 Simplified representation of N TCNQ- ions within a linear row A, undistorted structure B, distorted structure. (After Vegter and Kommandeur, 1975)...

Fig. 2.11. Linear row of grains of identical length L, doping A, and with grain barriers of height b caused by a continuous distribution of electron trap states of density At [142]. Two different transport paths for electrons are indicated TE, thermionic emission across the barrier T, tunneling through the barrier...

When the agarose is set, punch out from the gel a linear row of 2.5-mm diameter wells (5- or 7-mm distant from each other) and 0.5 cm in from the separadon between agarose and antibodycontaining agarose (Fig. la). 

The location of the cation in these canal compounds is not clear, but the cation definitely influences the nature of the crystal which is formed. With sodium and lithium iodides, a form II type of complex crystallizes as hexagonal plates. In the sodium iodide-iodine complex, the inclusion compound is not stoichiometric but rather the iodine atoms are packed into the canals in linear rows, with a spacing not related to the spacing of the dextrin molecules. 

Ref. (6).f The most important consequence of weak localization on alumina is a resulting preference for the adsorption of linear Of near-line sample molecules. A linear molecule such as anthracene is better able to align with a linear row of adsorbent sites than is an angular molecule such as phenanthrene. As a result anthracene is adsorbed ort alumina more-strongly than is its isomer phenanthrene. ... 

Other automatic staining instruments place individual slides in a horizontal position with the reagents and buffers dispensed onto the tissue from above, using a dispenser, Teflon-coated pipettes or disposable pipette tips. The physical layout or format of such instruments determines their size and shape as well as their slide and reagent capacities. The instruments either arrange slides in linear rows (rectangular shape or array-format Stainer) or in a circular pattern (carousel-format stainer). In both of these layouts, reagents and buffers are dispensed from above the slides. ... 

The two electron pairs on beryllium require a linear arrangement. Because both pairs are shared by fluorine atoms, the molecular stmcture is also linear (row 1 in Table 12.4). 

Multi-tube or Needle Nozzles Multi-tube nozzles, often called needle nozzles, are attached to a common manifold (Fig. 4). Nozzles for flat wheels consist of a linear row of needles with a small gap between each one. The manifolds can be ganged together for wide grinding wheels, such as used for centerless grinding. For more aggressive processes, such as creep-feed grinding, needles can be arranged... 

The crystallisation from strained melt as for instance in a blown film or in the jet during fibre spinning produces a row nucleated structure. " Linear nuclei are formed parallel to the strain direction. They contain more or less extended polymer chains. Secondary epitaxial nucleation on the surface of such linear row nuclei produces folded chain lamellae which are oriented perpendicular to the strain (Fig. 6). In such a case the sample exhibits a high uniaxial orientation of chain axes in the strain direction with random orientation of the a- and b-axes perpendicular to it. If the growing lamellae exhibit a helical twist the chain orientation in the strain direction is very soon replaced by the orientation of the axis of maximum growth rate (b-axis in the case of polyethylene) perpendicular to the strain direction and a more random orientation of the remaining two axes (a- and c-axes in the case of polyethylene) with a maximum in the strain direction. Such a row nucleated structure has parallel cylindrical spherulites (cylindrites) as its basic supercrystalline element. 

The situation changes when adsorbates form polar or ionic bonds with the surface. For example, oxygen atoms on a silver (110) surface form linear rows...
