The use of infrared kinetic spectroscopy to study small free radicals
The technique of infrared kinetic spectroscopy has been used to study the reaction of the propargyl radical (C3H3) with nitric oxide (NO). The overall rate constant at the high pressure limit for the reaction was determined ...
Diode laser kinetic spectroscopy of formyl
A tunable diode laser infrared high-resolution spectrometer was constructed to study the spectroscopy and kinetics of free radicals. A method for producing diode laser frequency scans which are several wavelengths long, ...
Synthetic studies toward the total synthesis of (+)-anthramycin total syntheses of (+)-neothramycins A and B
Through the serendipitous discovery of a palladium catalyzed conversion of ethylthiol esters to their corresponding aldehydes, the pyrrolo (1,4) benzodiazepine systems found in (+)-anthramycin 1a* and (+)-neothramycins A ...
Synthesis, characterization and magnetic property studies of copper-based phosphate and silicate compounds containing nanosize transition metal oxide frameworks
The search for novel compounds with nanosize transition metal oxide frameworks is important for the study and understanding of materials with interesting and important magnetic and electronic properties. These low-dimensional ...
Asymptotics under self-intersection for minimizers of self-avoiding energies
A knot energy is a real-valued function on a space of curves which in some sense assigns higher energy values to more complicated curves. The key property of any knot energy is self-repulsiveness: for a sequence of curves ...
Density matrix calculation of surface enhanced Raman scattering for silver nanoshells coated with p-mercaptoaniline
The tremendous increase in Raman-scattered photons seen in Surface-Enhanced Raman Scattering (SERS) has led to its adoption as a common analytical laboratory tool in spite of lingering questions about the phenomenon. One ...
Synthetic studies towards the total synthesis of discorhabdin C
Two synthetic approaches towards the total synthesis of discorhabdin C (3) are described. The general strategy for construction of azacarbocyclic spiro dienone system is to employ an intramolecular para-phenolic alkylation ...
Environmental Response, Mechanisms, and Orientation of Diffusing Molecular Ions in Polyelectrolyte Thin Films
New electrochemical storage and conversion materials hold promise as important additions to the world's energy supply, and the growing ability to control both sequestration and transfer of charge and matter via functionally ...
