The work described herein details the synthesis and application of
biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents
on the aryl ring of the terminal acetylenic carbon. From this work, we
successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps
from inexpensive commercially...
A quadratic programming method was developed for the statistical
analysis of gas chromatographic data. The method was applied to
three types of flavor extracts, peppermint, hops and brewed tea. The
brewed tea data had to be abandoned because of the singularity of its
coveriance matrix. In all cases tried the...

The concentration of seventeen elements in two species of fungus
which cause wheat bunt disease, Tilletia caries (DC.)Tul. (TS) and
Tilletia controversa Kiihn (DS), were determined by instrumental neutron
activation analysis in 37 TS spore samples, and 31 DS spore samples.
Aluminum was chosen as a soil contamination...
Acetylbenzoyl reacted with dimethylamine hydrochloride
and benzaldehyde in primary isoamyl alcohol under
reflux conditions to form 1,4-diphenvl-3-butene-1,2-dione,
compound I, which melted at 56-57°C.
Compound I formed a quinoxaline derivative, compound
II, which melted at 152.5-153°C.
Compound I was cleaved by hydrogen peroxide to form
cinnamic acid, compound III, which melted...
New methods, sensors, and devices based on redox indicators were developed to
monitor redox conditions in anoxic and anaerobic laboratory systems and the subsurface
environment. The primary application was monitoring redox conditions
during the dechlorination of tetrachioroethene (PCE) to ethene (ETH) in packed
columns and microcosm bottles containing an enriched...
The nuclear reaction ¹⁰⁰Mo(¹²⁴Sn,xn)[superscript 224-x]U has been carried out at E[subscript cot] of 578 MeV and 634 MeV using the facilities and equipment at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL) in order to initiate the search for the inverse fission of uranium. Reference...
The development and optimization of a fluorometric reaction
rate method for the determination of aluminum is described.
Modifications to existing instrumentation permit automatic
monitoring and reporting of measurement conditions. Automatic
correction of measured analytical signals is provided if monitored
parameters deviate from optimum values. A computer controlled
standard addition procedure...
