The Boron-Carbon System: Quarterly Report Number 2, August - October 1960

Description: Abstract: A definitive investigation of the boron-carbon equilibrium system is being made by X-ray diffraction, metallographic, and thermal analytical techniques. Additional baron-carbon alloys have been prepared by sintering and arc-melting compacts prepared from boron and high-purity graphite. Metallographic examinations of these alloys are in agreement with alloys previously preapred from lampblack. X-ray investigation of sintered compacts indicates that the solubility range of boron carbide… more

Preparaion of a Substance for the Prevention of Vascular Damage Due to Radiation

Description: "In our original proposal it was pointed out that we had obtained, b the successive treatment of adrenochrome with mineral acid and thiosemicarbazide, a black material which proved to be effective in preventing vascular damage cause by snake venom, radiation and thermal burns. Since the effectiveness of this preparation varied widely with different samples it was suspected that the product did not have a uniform composition. As a results of the inability of effect a separation or purification o… more

Seebeck Effect in Magnesium Silicide

Description: From abstract: "The Seebeck coefficient (thermoelectric power) has been measured from 7°K to 1000°K for both n-type and p-type single crystals of Mg2Si...The phonon contribution, Sp, was obtained from the measured Seebeck coefficient by subtracting off the electron diffusion term, Se, which was calculated with the aid of the measured Hall coefficient. The magnitude of Sp was observed to be proportional to T-3 and to show the dependence on sample size and on carrier concentration predicted by th… more

Mass Transfer Coefficients and Interfacial Area in a One Stage Pulse Column

Description: From abstract: "Over-all mass transfer coefficients were determined by considering the operation of the pulse column to be a stage-wise process. The area for mass transfer was obtained by direct photographic measurements...The mass transfer coefficient was found to increase when the interfacial tension was reduced..."

Microwave Measurements of Hall Mobilities in Semiconductors

Description: From abstract: "The Hall mobilities of germanium single crystals were measured with a microwave frequence of 9000 Mc/sec over the temperature range 30°K to 300°K. A rectangular sample occupied the central part of the wall of a rectangular cavity, which was doubly generate in the TE101 mode and in the TE011 mode at a single resonance microwave frequency. The external magnetic field and microwave field associated with one of the two modes gave rise to the other mode of oscillation, owing to excit… more

Data Processing For Bubble Chambers

Description: The computer program which performs spatial reconstruction of events photographed in a bubble chamber is required to eliminate human and digitizer errors. It recognizes and corrects for single nuclear scatterings in the presence of multiple Coulomb scatterings. Momentum components are determined and kinematic constraints are applied. Measured parameters are performed into special reference frames and quantities of physical interest are calculated. Results are stored in a tape file containing al… more

Photoproduction Of Neutral Pions As A Function Of Mass Number

Description: The relative yield of neutral photopions from various elements was determined as a function of the quantum limit energy of the Berkeley synchrotron. Single decay photons from neutral pions were observed at 45, 90, and 135 deg to the incident bremsstrahlung in the laboratory system. Mean free paths for neutral pions in nuclear matter were obtained, an optical model prediction of the photopion yields based upon pion-nucleus scattering data was confirmed, and the presence of coherent pion producti… more

A Study of the Mechanism of Radiation Induced Gelation in Monomer-Polymer Mixtures

Description: "Additional mixtures of polymers and multi-unsaturated monomers have been prepared, irradiated and the gel content determined. The gel content determination of crosslinked polyolefins has been investigated in detail. The multi-unsaturated monomers used and radiation conditions applied up to this time have not given significant gel contents for polypropylene. the polypropylene resin used has been characterized by differential extraction."

Molecular Association and Electronic Structures of Nickel (II)

Description: "A new phenomenon which can, under certain circumstances, account for anomalous magnetic and spectral behavior of planar nickel(II) complexes has been discovered. This is a molecular association of the solute molecules in solvents of low coordinating power. It is shown that the magnetic moment and spectrum of bis(2.6-dimethyl1-3,5-heptanediono)nickel(II), Ni(DIBM)z, dissolved in toluene, are dependent upon both temperature and concentration.

Utilization of Radiactive Isotpoes in Coal Process Research

Description: "With careful attention to details, tritium assays of satisfactory accuracy have been achieved on low activity standard samples by dry combustion and liquid scintillations counting of the product water.This method is faster, more accurate and dependable than the zinc fusion-ion chamber method fro low level tritium assays. At 380 degrees C, tritium loses from hydrocarbon tracers by isotopic exchange is significant and must be corrected for in tracer measurements at this elevated temperature."
