[36] Carotenoid photobleaching
1999Publisher Summary This chapter discusses carotenoid photobleaching. Carotenoids are strongly colored naturally occurring pigments found in plants and animals. In addition to imparting color, carotenoids serve two purposes in food: (1) as photo protecting agents, and (2) as primary antioxidants by quenching free radicals, including free radicals ...

Photobleaching Flow Visualization
1991The present paper describes an experimental flow visualization technique that is suitable for thermal convection studies. The method non-intrusively generates neutrally buoyant time line and time streak markers. A microcomputer-based video data acquisition system is used to process the images.

Fluorescence Photobleaching Techniques
1991In the early 1970s fluidity became a central topic of membrane biology. The classical paper by Singer and Nicolson (1972) on The fluid mosaic model of the structure of cell membranes’ integrated current speculations and results by visualizing the plasma membrane as a fluid lipid bilayer decorated and intercalated with proteins.

Photobleaching—a Common Phenomenon
Nature, 1968YELLOWING or darkening in sunlight is a common occurrence. Ultraviolet light with photon energies in excess of bond energies disrupts molecules and produces coloured and/or reactive groups. Wool yellowing increases below 365 mµ; at 254 mµ greening and free radicals occur1,2. Other materials form free radicals3. Skin reddens only below 320 mµ (ref.

Kinetic models of photobleaching
1992The photochemical bleaching of dye by light is a long-standing problem for the textile and graphics industries. However, the effects of photochemical bleaching can also be employed usefully to alter the index of refraction of a material to fabricate an optical waveguide in polymeric materials.
