Cinema Enhances Sociological Questions,l organelles in a natural state. For such investigations, the wavelength region between 2.3 nm and 4.4 nm is best suited because there is about an order of magnitude difference between the absorption coefficients for water and protein. This difference provides a natural contrast mechanism for the investigation of wet biological materials.

The physics required to describe the transport of charges and of phonons changes when the carriers are confined in a small structure — the very smallness of the structure affecting the dynamics of the carriers. In biology microelectronic techniques have been used to make microelectrodes.

High Resolution Electron Microscopy in Materials Science,henomena in crystals and to a much smaller extent on absorption effects; the reverse is true for the imaging of biological material. In both cases “phase contrast” effects play an important role as well.

Scattered Electrons in Biological Structure Determination,tion. Its cross-section of interaction with matter is sufficiently small to penetrate a specimen 100 nm thick with ease, but large enough to interact at least once in that thickness. In addition it can be focused by electrostatic and magnetic fields, permitting the construction of electron microscopes.

Synchrotron Radiation and the Submicron World: Selected Activities at the Daresbury Laboratory, UK,mers, and other materials in both crystalline and amorphous forms. This review outlines the principles of SR production and indicates how SR is being applied to a variety of x-ray imaging problems. This theme is illustrated by references to the SR source (SRS) at the Daresbury Laboratory.
