SPECTROSCOPY

Spectroscopy covers resources concerned with the production, measurement, and interpretation of electromagnetic spectra arising from either emission or absorption of radiant energy by various sources. This category includes resources that report on any of several techniques for analyzing the spectra of beams of particles or for determining mass spectra.

CHEMISTRY, ANALYTICAL

Chemistry, Analytical covers resources on the techniques that yield any type of information about chemical systems. Topics include chromatography, thermal analysis, chemometrics, separation techniques, pyrolysis, and electroanalytical and radioanalytical chemistry. Some spectroscopy resources may be included in this category when focusing on analytical techniques and applications in chemistry.

MATERIALS SCIENCE, COMPOSITES

Materials Science, Composites covers resources that focus on mixtures or mechanical combinations of two or more materials that are solid in the finished state, are mutually insoluble, and differ in chemical nature. The major types of composites are 1) laminates of paper, fabric, or wood and a thermosetting material; 2) reinforced plastics; 3) cermets (ceramic and metal powders); 4) fabrics of natural and synthetic fibers; and 5) filled composites, in which a bonding material is loaded with filler in the form of flakes or small particles.
