The diffusion coefficient of propane in helium

Creator:: Tang, Fa-tai
Abstract:: A specially designed gas chromatograph with both TCD and FID has been tested for the measurement of the diffusion coefficients of methane and propane in helium. Knox's arrested elution technique(⁴) was used and yielded a value of 0.6431 cm²/sec averaged with the value obtained by Yang and Hawkes(⁷). Values of...

Gold Nanostars: Spectroscopic and Physical Properties

Creator:: Zhou, Lixia
Abstract:: Tethering fluorophores on metal nanoparticles for metal enhanced fluorescence (MEF) has attracted a lot of attention from scientists interested in fluorescence based approaches. MEF has many benefits in fluorescence related techniques, because the analytical signal increases and enables potentially lower detection limits or better sensitivity. Many types of nanoparticles have...

Total synthesis of indole alkaloids: pt. 1. Asymmetric synthesis of (-)-ibogamine. pt. 2. An approach toward the synthesis of koumine

Creator:: Choi, Younggi
Abstract:: PART I. The preparation of (-)-ibogamine (1) in fourteen steps from benzoquinone and in 10% overall yield is a powerful illustration of the value of the asymmetric Diels-Alder reaction as a starting point in a multistep synthesis. All four cycloadducts, 70, 77, 84 and 96, obtained with the (S)-BINOL-TiCl₂ complex...

Total Synthesis of Aspidosperma Alkaloids Leuconoxine, Melodinine E and Mersicarpine and Synthetic Studies directed toward the Iboga Alkaloid Ibogaine: Progress directed toward the dimeric Cephalotaxus Alkaloid Cephalancetine C

Creator:: Kim, GilSoo
Abstract:: The first part of this manuscript is about the total synthesis of the aspidosperma alkaloids leuconoxine, melodinine E and mersicarpine. Our synthetic strategy used a radical translocation-conjugate addition cascade to construct the core of the natural product. Specifically, a vinyl radical was generated from the homolysis of the C–I bond...

Some biochemical studies of phenylmercuric acetate and mercuric acetate toxicity in rats

Creator:: Ellis, Robert William
Abstract:: Biochemical studies of phenylmercuric acetate (PMA) and mercuric acetate toxicity in rats carried out during this investigation were (1) the metabolism of ²⁰³Hg(Ac)₂ and ²⁰³Hg-PMA within kidney and liver tissues following oral ingestion, (2) the effect on some soluble enzyme activities and determinations of ²⁰³Hg binding in the enzyme fractions,...

Analytical methods for the study of migration of chloride ions in reinforced concrete under cathodic protection

Creator:: Orlova, Nadejda V.
Abstract:: The migration of chloride ions in concrete with steel reinforcement under cathodic protection was investigated. Mortar blocks (15 cm x 15 cm x 17 cm) of various composition (water to cement ratio, chloride ion content) were cast with an iron mesh cathode embedded along one face and a thermally sprayed...

A chemical and petrological study of igneous lithic clasts from the kapoeta howardite

Creator:: Smith, Monty Ray
Abstract:: Instrumental and radiochemical neutron activation analyses supported by electron microprobe mineral analyses (Paul Warren, University of New Mexico) and petrographic observations are presented for approximately forty individual clasts separated from the Kapoeta howardite. These clasts are classified into eucritic, cumulate-like, mafic (plagioclase ± olivine-bearing pyroxenites), pyroxenite, polymict and/or metal-rich and...
