    On the e-process - Its components and their neutron excesses (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: The pattern of abundances within the iron-abundance peak of the solar system is analyzed for various Cr, Fe, and Ni abundances, and a method is developed for finding the best fit to a given set of abundances with a chosen number of zones, i.e., mass contributions characterized by differing values of eta. This material can be synthesized by a superposition of e-process compositions in a low-eta region (eta = 0.003) and a high-eta region (eta = 0.065 -0.080) with at least 85% coming from the low-eta region. Addition of a third eta zone is unproductive. The applicability of the particle-poor freeze out is discussed in the light of these abundances, and the results of employing different numbers and types of zones are interpreted as an indication of the relative abundances themselves. Ejection of the low-eta zones is of great interest in gamma-ray astronomy and for empirical testing of theories of nucleosynthesis. The distribution of high zones should give important information about the formation of collapsed remnants.

    Effect of phase-volume ratio and phase-inversion on viscosity of microemulsions and liquid crystals (1974)

    Notes: Microemulsions, which are optically transparent oil-water dispersions, were spontaneously produced upon mixing hexadecane, hexanol, potassium oleate, and water in specific proportions. The viscosity of the microemulsions was measured for several water/oil ratios including the phase-inversion region. The striking optical and viscosity changes observed at specific water/oil ratios were in agreement with the proposed mechanism of phase-inversion, namely, water spheres → water cylinders → water lammellae → continuous water phase, for this system. In the phase-inversion region, the dispersion exhibited birefringence and rheopectic properties. An extremely high viscosity (〉 100,000 cps) exhibited by the dispersions between water/oil ratios of 2.0 and 3.5 were explained in terms of ion-dipole association between oleate and hexanol molecules on adjacent droplets.

    Lithography and radiation chemistry of epoxy containing negative electron resists (1974)

    Notes: A class of negative electron-beam resists is described which have excellent lithographic characteristics. The resists are copolymers of glycidyl methacrylate and ethyl acrylate. Their molecular weights, epoxy contents, and polydispersivities can be controlled to give an adjustable range of electron sensitivity and contrast. The copolymers are compared to other epoxy containing, negative electron-beam resists.Micrography of resist profiles generated from a single line scan of the electron beam have been used to illustrate the complex interaction of accelerating voltage of the electron beam and resist contrast on resolution. Optical gratings made from single line scans of the beam have feature sizes less than 300 nm in the resist, etched metals, and dielectrics.

    Nature of fatigue behavior and effect of flaw size in polystyrene (1974)

    Notes: Fatigue tests under reversed tension-compression have been made on polystyrene specimens in both the unnotched and notched condition. For the notched specimens subject to a stress amplitude of 2500 psi, the log of the fatigue life was found to be a linear function of the log of the notch size. From the data, it was possible to determine an inherent flaw size for polystyrene subject to alternating loading and this value is compared to corresponding values obtained from static tests. Fracture surfaces were examined by scanning electron microscopy and the changes produced by notching are discussed.

    The C-12/C-13 ratio in stellar atmospheres. II - CN and CO in alpha Orionis (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: The isotopic abundance ratio C-12/C-13 for the M supergiant alpha Orionis is derived from photoelectric high-resolution scans of the CN 2-0 red system and high-resolution interferometric spectra of the CO second-overtone bands. The two molecules yield consistent results and the final value for the C-12/C-13 ratio is 7.0 plus or minus 1.5. Rationale is offered for the causes contributing to an earlier suggestion that C-12/C-13 ratios from CO and CN were in disagreement.

    Near-earth cosmic dust results from S-149 (1974)
    In:  Other Sources
    Details
    Publication Date: 2019-07-27
    Description: Three space exposures (34, 46 and 33 days) of thin films and polished metal plates with a total area of 0.12 sq m per exposure were carried out during Skylab via the S-149 experiment. Study of the materials recovered indicates that the S-149 experiment contains important information concerning cosmic dust in the near-earth vicinity. Craters and penetration holes have been found ranging from 135 micron diameter to less than 0.5 micron. A cosmic dust flux curve in the mass range from 10 to the minus 16th to 10 to the minus 7th grams is presented. Evidence is given concerning the directional characteristics of the particles and their breakup in near-earth space is presented.

    Coagulation of lead chloride aerosol in the presence of water vapor (1974)

    Notes: Polydisperse submicronic lead chloride aerosols were generated from melt phase under dry and humid conditions. The particle size and concentration increased with increasing generation temperature. The aerosol particles generated in a dry atmosphere were pherical while the aerosol particles generated in humid atmosphere showed development of crystallinity at the surface.Coagulation rates of the aerosol generated in a dry atmosphere were measured at room temperature under different humidities. The coagulation rates were in goodagreement with Smoluchowski's theory, modified to include the effect of polydisperisity and were unaffected by humidity. The interaction of lead chloride particles with the water vapor was characterized by a process of adsorption a the interfce. The coagulated aerosol exhibited a chain structure for humidities lower than 70% and, at higher humidities, compact agglomeration was observed.
