In this thesis, we investigated the surface composition and orientation of both pure room-temperature ionic liquids (Ils) and binary mixtures of the ILs of the type consisting of the 1-alkyl-3-methylimidazolium ([C[subscropt n]mim]⁺, n=4, 8, and 12) cation coupled with either [PF₆]⁻, [BF₄]⁻, [Cl]⁻, or [Br]⁻. The surfaces of the ILs...
The study of natural products (NPs) and their application has shaped humanity. Starting with the idea of using plants as medicine, it has now grown into the science of purifying and identifying organic molecules from nature to study their inherent biological activities. Understanding the molecular structures of NPs is the...
Little is known regarding the catabolic mechanisms involved
in the breakdown of glucose in mung bean (Phaseolus aureus)
seedlings. Studies in other laboratories have shown that the TCA
cycle pathway is operative in mung bean leaves, and have demonstrated
the presence of enzymes for the oxidation of glucose to
glucuronic...
The rate of interaction of carbon dioxide with eight detached organic films commonly used as coatings for metal surfaces was examined.
The films studied were lacquers of several different formulations
including oleoresinous, phenolic, vinyl, alkyd, epoxy, and
hydrocarbon types. The sorption was measured on a McBain type
gravimetric adsorption balance...
The velocity of sound in gases was measured, using an ultrasonic
wave train as a diffraction grating. The fundamental problems
involved in the optical technique are discussed. An apparatus utilizing
an objective lens of focal length 1.5 m and aperture f/20 was constructed
and used at an ultrasonic frequency close...
