Few discoveries of any importance have been the result of a moment's happy coincidence; rather have they been the fruit of many hours of tedious thought and experiment. This is especially true in the realm of organic chemistry. Here, where progress is made only by the most painstaking experimentation, extensive...
We report the use of MIL-120 as a water-stable and cost-effective metal-organic framework (MOF) for selectively capturing CO₂ from wet flue gas. Synthesized using inexpensive and environmentally benign reagents in water, MIL-120 possesses one-dimensional pores decorated with hydroxyl-bridged Al(III) ions and benzene rings with an interstitial spacing of 4.78 Å....
Aqueous complexation of Th(IV), U(IV), Np(IV), Pu(III/IV), and Ce(III/IV) with DTPA was studied by potentiometry, absorption spectrophotometry, and cyclic voltammetry at 1 M ionic strength and 25 °C. The stability constants for the 1:1 complex of each trivalent and tetravalent metal were calculated. From the potentiometric data, we report stability...
The electrochemistry of cadmium at a Reticulated Vitreous
Carbon (RVC) electrode has been studied to determine the suitability of
RVC as a working electrode for the electrochemical preconcentration of
cadmium in the corrosive environment of zirconium dissolved in
hydrofluoric acid.
The electrochemistry in this investigation deals with deposition
of solid...
A variety of laser spectroscopic methods are employed in this
thesis research for studies of CF₃NO, an interesting model
photodissociative system, and for investigation of low energy rotations
and vibrations of small molecules and low molecular weight clusters in
free jet expansions.
Nonradiative energy decay for electronically excited CF₃NO is...
The development of a least squares model for the
determination of compliance constants from various combinations
of vibration frequency, mean square amplitudes
of vibration and centrifugal distortion data is discussed.
The resultant model is applied to frequency and mean square
amplitude data for NO₂ and N₂O₄ and to frequency and...
The recent quest for improved functional materials like high permittivity dielectrics and/or
multiferroics has triggered an intense wave of research. Many materials have been checked for their
dielectric permittivity or their polarization state. In this report, we call for caution when samples are
simultaneously displaying an insulating behavior and a...
Isomerically pure cis,cis,trans-1-pheny1-1,3,5-
heptatriene was prepared and cyclized. Ring closure
was followed by a 1,5 hydrogen shift, and the only product
observed was 1-phenyl -6-methyl -1,3-cyclohexadiene.
Rough first order rate constants for thermolysis and
the hydrogen shift were determined. Kinetic estimates
indicate that the report of disallowed product in a...
