The silicate phases of 11 pallasites were analyzed instrumentally
to determine the concentrations of some major, minor, and
trace elements. The silicate phases were found to contain about
98% olivine with 1 to 2% accessory minerals such as lawrencite,
schreibersite, troilite, chromite, and farringtonite present. The
trace element concentrations, except...
Basalts of both Eocene and Miocene age from several groups
along the Oregon and Washington coasts have been analyzed for some
major, minor, and trace elements using instrumental neutron activation analysis (INAA). The rare earth element (REE) patterns observed
in these samples are used for comparisons within the groups studied...
The spectrophone method for the study of vibrational relaxation
has been claimed to possess a distinct advantage over the more commonly
used ultrasonic techniques in that it permits the relaxation of
the various infrared-active vibrational modes in a polyatomic molecule
to be studied separately. A discussion of the rate equations...
Steroid carbenes have been investigated as synthetic intermediates.
Basic decomposition of 4-en-3-one tosylhydrazones (and
other A-ring systems) gives varying amounts of 2, 4-dienes, and
solvent derived products with diglyme, heptane, tetrachloroethylene,
carbon tetrachloride, benzene and cyclohexene. A method for
separating complex product mixtures was developed and a study of
the...
The 3-cyclohexenyl carbinyl carbene species was formed by the
thermal decomposition of the p-toluenesulfonylhydrazone sodium
salt and by oxidation of the hydrazone. Several oxidizing agents
were studied. The products were investigated under aprotic and
protic conditions and at various temperatures. The diazocompound
was formed as an intermediate and found to...
Graphite oxides which had been prepared from three different
size graphite particles by the modified Brodie method were observed
with the electron microscope. The thermal decomposition products
of the oxides, obtained by heating them at 240° and 300°,
were observed using the electron microscope and x-ray diffraction.
Graphite oxide was...
