Fig. 6.1 The fundamental structural unit found in the Chevrel phases (cluster MoeXg full circles Mo atoms) displayed in three ways to emphasize different views of the connectivity. In (a) an octahedron of molybdenums (Mo-Mo = 2.7 A) is encased in a cube of chalcogens (Mo-S 2.45 or Mo-Se 2.6 A). Scheme (b) exhibits the same cluster as consisting of an octahedron with its triangular faces capped by chalcogenides. In (c), the cluster has been reoriented so that a threefold axis is vertical.

Figure 30. Two cases of the polygonal surface representation in a single triangular pyramid (tetrahedron). The black and white circles represent the point with higher and lower values in comparison with the threshold value. The gray area is sthe schematic representation of the surface inside the pyramid (see Fig. 29).

Figure 4. Triangular phase diagram, showing partitions of R2ar. / gc, and at fixed Q > ab + bc + ca- Physically allowed combinations lie inside the circle, with the conical intersection, corresponding to equilateral triangular ABC, at the center.

Fig. 17. STM image of thiophene on the triangular M0S2 nanoclusters at a sample temperature below 200 K. Thiophene molecules are evident in positions on top of the bright brim associated with an edge state (dark circles), and additionally thiophene decorates the perimeter of the cluster (gray striped circle). For clarity, the color scale in this image is circled twice to enhance contrast. At temperatures > 240 K, no indications of adsorbed thiophene were observed with STM.

Fig. 18. Atom-resolved STM image (F, = —8.5mV, 7, = 1.12nA) of a triangular single-layer M0S2 nanocluster after reduction with atomic hydrogen atoms at 673 K in 5 min. Image size 46 A x 47 A. The location of two sulfur vacancies is illustrated with circles. Reprinted with permission from Reference (US ). Copyright (2000) by the American Physical Society.

Figure V l 4. Kagome lattice in the triangular lattice of cobalt ions, (a) Solid circles indicate the cohalt ions in Fig. 1(b). Gray triangles form a Kagome lattice which is made by a trace of the travel of an electron starting from zx,l> (see text), (b) Layout of the four (gray, black, hatched and white) Kagome lattices...

Figure 10 Crystal structures of CA with acetic acid (a) 1 1 crossing structure and (b) 1 2 bilayer structure. Crystal structures of CAM with acetonitrile and water (c) 1 1 1 triangular structure and (d) 1 1 2 bilayer structure. Open, gray and filled circles represent carbon, nitrogen and oxygen atoms, respectively. Hydrogen atoms are omitted for clarity.

FIGURE 25 Projection of the La4NijPb4 structure onto theab plane. Lanthanum, nickel, and lead atoms are drawn as medium gray, black filled, and open circles, respectively. The lead chains and the triangular nickel units are emphasized. The bottom drawing shows the polyhedra of coordination number 12 for the La2 (gray shading) and Pb2 atoms. 

Each set of values /ajg for normal mode p forms a N x N matrix, where N is the number of nuclei. A diagonal term Jaa p represents the contribution which atom a makes to Jp, and the sum Ja/3 p + the contribution due to the coupled motion of the pair of nuclei a and / . The graphical representation as full and empty circles, depending on the sign, in a matrix, in upper triangular form, maps the way nuclear motion creates Raman and ROA intensity in the vibrating molecule [42],... 

Fig. 2. Effect of exogenous gelatin [46] and PVP [47] on the production and stability of a murine antibody heavy chain. Triangular symbols indicate PVP, diamonds indicate gelatin, and circles indicate no stabilizer (control). In the upper portion of the figure, the intracellular protein is unaffected by the addition of exogenous stabilizers. In the lower portion of the figure, added PVP and gelatin significantly increase the level of extracelluar protein product...

Fig. 4. Increased recovery of plant-produced GM-CSF and murine antibody in the affinity chromatography bioreactor (ACBR). Triangular symbols represent GM-CSF production and circles represent antibody production. Closed symbols indicate normal batch production and open symbols indicate ACBR production. For both products, protein recovery is increased several-fold using the ACBR [62]...

For the triangular geometry, we consider the adsorption space as being a prism, whose cross section is an equilateral triangle, formed by three semi-infinite walls, each wall consisting of 4 graphite planes. The size of the pore, d, is taken as the diameter of the inscribed circle The axis of the pore runs along the xe (0,/-) coordinate, with L =21 nm and periodic boundary conditions in x. 

Schulz and Asumnaa (48), based on their SEM observation, assumed that the selective layer of an asymmetric cellulose acetate membrane for reverse osmosis consists of closely packed spherical nodules with a diameter of 18.8 nm. Water flows through the void spaces between the nodules. Calculate the water flux by Eq. (30) assuming circular pores, the cross-sectional area of which is equal to the area of the triangular void surrounded by three circles with a diameter of 18.8 nm (as shown in Eig. 8). 

FIGURE 3.2 Proposed epitaxial relationship between an unreconstructed (1 x 1) diamond surface (thin triangular net), a buckled reconstructed (111)-(2 x 1) surface (open circles) and a 2-D hexagonal (00.1) surface of carbyne (solid circles, thick lines).
