Elements microscopic study

Electron-microscopical studies indicated that mGluR5 was mainly localized in somatic and dendritic profiles expression of mGluR5 immunoreactivity was observed in the postsynaptic elements in the hippocampus (Lujan et al., 1996, 1997 Hanson and Smith, 1999), basal ganglia (Shigemoto et al., 1993 Hanson and Smith, 1999), thalamus (Godwin et al., 1996 Liu et al., 1998), hypothalamus (Romano et al., 1995 Van den Pol et al., 1995), cerebellar cortex (Negyessy et al., 1997), dorsal cochlear nucleus (Petralia et al., 1996b), and dorsal horn of the spinal cord (Vidnyanszky et al., 1994 Jia et al., 1999).

Support for the project under EMSP Contract DE-FG07-97ER62522 is gratefully acknowledged. Dr. Edith Robbins, New York University School of Medicine, Department of Cell Biology, performed the scanning electron microscope studies of the screen filter elements, dius providing the necessary data for Ae screen collection efficiency. 

An electron microscopic study of fine-pored silica gel by Sugar and Guba (119) revealed that the structure indeed was made up of a threadlike or fiberlike network, but the fibers were made up of chains of spheres. The pore volume determined by adsorption could be correlated with the observed size and spacing of the chains of particles on the assumption that these were on the average cylindrical and that the pore space was the complementary space of a skeleton built up of the network of cylindrical elements.

Microchemical or ultramicrochemical techniques are used extensively ia chemical studies of actinide elements (16). If extremely small volumes are used, microgram or lesser quantities of material can give relatively high concentrations in solution. Balances of sufficient sensitivity have been developed for quantitative measurements with these minute quantities of material. Since the amounts of material involved are too small to be seen with the unaided eye, the actual chemical work is usually done on the mechanical stage of a microscope, where all of the essential apparatus is in view. Compounds prepared on such a small scale are often identified by x-ray crystallographic methods.

The twenty-first century demands novel materials of the scientist. New instruments have made possible the field of nanotechnology, in which chemists study particles between 1 and 100 nm in diameter, intermediate between the atomic and the bulk levels of matter. Nanotechnology has the promise to provide new materials such as biosensors that monitor and even repair bodily processes, microscopic computers, artificial bone, and lightweight, remarkably strong materials. To conceive and develop such materials, scientists need a thorough knowledge of the elements and their compounds.
