Describes an experimental approach for controlling fusion that involves a toroidal device that holds and heats reactive isotopes of hydrogen with a magnetic field. (GS)

Describes an experiment in which Fresnel diffraction patterns were observed with a beam of slow neutrons of wavelength 4.33 Angstroms. (MLH)

Describes how the use of tunable lasers in coherent Raman techniques allows spectra to be taken for samples in which spontaneous Raman scattering is intrinsically weak. (MLH)

Discusses the graphite to diamond transformation and a phase diagram for carbon. Describes high temperature-higher pressure experimental apparatus and growth of diamonds from seed crystals. Reviews properties of the diamond which suggest uses for the synthetic product. Illustrations with text. (GH)

Discusses dichlorodiammineplatinum's ability to inhibit bacterial cell divisions and its use as an antitumor agent. (SL)

Discusses the renewed interest in superconductivity research and describes the differences between the two basic types of superconductivity. (MLH)

Discusses a new branch of optical spectroscopy that deals with the optical analogs of spin transients and provides ways to explore dynamic interactions in optically excited materials. (MLH)

Lists activities of the February 2-5, 1976, joint meeting of The American Physical Society (APS) and the American Association of Physics Teachers (AAPT) in New York city. (CP)

Describes liquid surface holograms including their application to medicine. Discusses interference and diffraction phenomena using sound wave scanning techniques. Compares focussing by zone plate to holographic image development. (GH)

Reviews the Hafele-Keating experiment on relativistic changes in eastward and westward moving cesium atomic clocks. Recommends the use of the Sagnac effect to remove the east-west time asymmetry and of the general-relativistic effect to elucidate the clock-rate changes. (CC)

Discussed is the use and worth of any studies on animals in research. Topics included are human benefit, anthropomorphism, ecology, and the psychology of the use of animals in research. (DS)

Outlines general principles in observing sharp electron spin resonance (ESR) lines in the solid state by incorporating the transition metal ion of interest into an isostructural diamagnetic host material in small concentration. Examples of some recent studies are described. (CS)

Considers a few areas of oxide/sulfide and intercalation-type chemistry. Discusses synthesis of the disulfides of the metals of group IVB, VB, and VIB; the intercalation reaction between lithium and titanium disulfide; other intercalates; and sulfide catalysts. (CS)

Presents an exact solution to the nonlinear Faraday's law problem of a rod sliding on frictionless rails with resistance. Compares the results with perturbation calculations based on the methods of Poisson and Pincare and of Kryloff and Bogoliuboff. (Author/GA)

Discusses new techniques for studying reactions that occur in the picosecond range and how the results of this research provide new insights into biochemical events and the chemical processes that take place in liquid systems. (MLH)
