Biological disc

The cake baffle disc was patented more than 15 years ago by the then Pennwalt/Sharples company [7]. It has been variously known as the Lee disc (after the inventor), a BD disc, biological disc or a baffle disc. Together with a negative ring dam (pond level higher than the cake discharge) it was known...

Such an ordered organization of biological photoreceptor molecules appears to be a common feature (which, of course, is hardly detected in more opaque, highly scattering biological material). In the vertebrate rod maximum absorption lies in membranes (discs) perpendicular to the long axis of the rods, but anisotropically within these planes47).

Solvent-extracted delignified beech wood pulp was treated with potassium tertiary butoxide, then with quinone methides at 25 °C or 45 °C (Figure 4.13). Following reaction, extensive solvent extraction was then performed, and the modified flour was pressed to form a disc, which was then exposed to C. versicolor or G. trabeum. No indication of biological attack was found (Loubinoux etal., 1992).

In many cases, these polymer chains take on a rod-like (calamitic LCPs) or even disc-like (discotic LCPs) conformation, but this does not affect the overall structural classification scheme. There are many organic compounds, though not polymeric in nature, that exhibit liquid crystallinity and play important roles in biological processes. For example, arteriosclerosis is possibly caused by the formation of a cholesterol containing liquid crystal in the arteries of the heart. Similarly, cell wall membranes are generally considered to have liquid crystalline properties. As interesting as these examples of liquid crystallinity in small, organic compounds are, we must limit the current discussion to polymers only.
