Fig. 4 Representation of the various types of internal organisation that may occur in micelles formed through co-assembly of charged block copolymers. Depicted are micelles with a corona consisting of two different neutral monomers (shown in blue and green) that are (a) mixed, (b) laterally segregated, (c) radially segregated, and (d) laterally and radially segregated. Both cen-trosymmetric micelles (a, c) and non-centrosymmetiic micelles (b, d) are depicted. The micelle with a laterally segregated corona is generally referred to as a Janus micelle (b). The micelle depicted in (c) is most commonly known as onion-like or core-shell-corona micelle. The micelle with a laterally and radially segregated corona (d) is usually called a patched micelle. Note that in the case of (c) and (d) the blue and the red/black chains may also switch position...

The issue of appearance is central to Allen s work. Allen s trademark hair is imruly, badly cut, frizzy, and red. Here is another vestige of the wildman. Allen s shlubbiness is as deliberately contrived and as carefully tailored as Bond s tuxedos. For exanple, fashion designer Ralph Lauren created the clothes in Annie Hall. However, when Woody Allen wears a tuxedo, he is not the elegant desirable bachelor around town, he is a manservant/waiter robot in Sleeper. Instead of Janies Bond 007, he is Janus 414 in whiteface. 

Fig. 30 Schematic phase morphologies of binary cylindrical bottle brushes Janus cylinder (left), Janus dumbbell (middle) and lamellar-like (right) morphologies. The red and blue domains are filled by the A and B monomers interfacial regions are green. From [99]...

Fig. 54 TEM micrographs of nanobjects made of PS83g-b-PMMA945 and hexadecane (ratio 1 1) with increasing amount of SDS. Their morphology changes from (a) nanocapsule (low coverage of SDS, 0.67 wt%) to (b) a Janus-like structure (high coverage of SDS 3.33 wt%). The insets represent the morphology in aqueous phase with the copolymer (black) and hexadecane (red) the latter is evaporated in the electron microscope and therefore not visible on the TEM micrograph [221].

Cationic dyes acridine orange, crystal violet, Janus green B, methyl violet, neutral red, Pyronin B, Pyronin Y (G), Safranin, Victoria blue B, and Victoria blue 4R, commonly used in histology, were studied by TLC on the Marshall and Lewis system (115). Marshall also separated some Sudan dyes, used for the histological staining of fats, on silica gel TLC sheets using benzene-CHCl3 (10 1) as the mobile phase (115).
