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, ...
Internal conversion spectra from heavy and medium weight nuclei
Abstract Not Available.
Lifetime of helium metastable spin-states in a helium discharge
The lifetime of a helium 23s1 metastable atom electronic spin-state is measured in helium gas using optical pumping techniques. The metastable atoms are created by an RF electrical discharge. The spin-state lifetime is ...
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 ...
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 ...
The HOG MAPK pathway and yeast stress responses: Roles in oxidative stress and heat shock
The HOG MAP kinase pathway in the budding yeast Saccharomyces cerevisiae senses and responds to high osmolarity. Here we demonstrated that HOG pathway mutants are hypersensitive to K1 killer toxin, which implies certain ...
A study of the urban heat island of Houston, Texas
The magnitude, spatial extent, growth, and seasonal and diurnal behaviors of the urban heat island of Houston, Texas are characterized using both in situ air temperature and remotely sensed surface temperature data. Between ...
Novel permanent-magnet Penning trap for studies of dipole-bound negative ions
Low-energy electron transfer between a Rydberg atom and a target molecule can result in formation of long-lived metastable negative ions. Here we describe a novel permanent-magnet Penning trap designed to examine the ...
Centrifugally Driven Radial Convection of Plasma in Saturn's Inner Magnetosphere
Theoretical studies have pointed out that in the inner part of a rapidly rotating magnetosphere such as that of Jupiter and Saturn, the dominant driving factor of radial plasma transport is the centrifugal interchange ...
