The extraction of niobium (V), tantalum (V), mercury (II), silver (I), cobalt (II), iron (III) and cadmium (II) by di(n-octyl) arsinic acid (HDOAA) in chloroform
(1975)
The extraction of Nb(V) and Ta(V) from HCl, H₂SO₄ and H₂C₂O₄ solutions, Hg(II) from HCl solutions, Ag(I) from HNO₃ solutions, Co (II) from HCl solutions, Fe(III) from HCl, HNO₃, H₂SO₄, and HCIO₄ solutions ...
The characterization and affinity labeling of the L-tryrosineL-phenylalanine transport system of Bacillus subtilis
(1975)
This dissertation describes the kinetics, specificity, mechanisms, and affinity labeling of the L-tyrosine/L-phenylalanine transport system in whole cells of Bacillus subtilis. The L-tyrosine/L-phenylalanine transport ...
The effect of fluorine as a substituent on bond dissociation energies
(1975)
The kinetics of the thermal and chemically activated elimination of HF from 1,1,1-trifluoroethane was analyzed resulting in DH₂₉₈₋ (CH₃-CF₃) = 101.2±1.1 kcal mol�¹ and ΔH°[subscript f](CH₃-CF₃,g,298) ...
Inner shell ionization of intermediate- and high-z elements produced by collisions with fast heavy charged particles
(1975)
A review of the theoretical approaches to inner-shell ionization in fast ion-atom collisions has been presented. K x-ray yields have been measured for ten elements ranging from Fe (Z = 26) to Au (Z = 79) using 30-100 MeV ...
Bond dissociation energies of selected fluorocarbons
(1976)
The gas phase reaction of 1,1-difluoroethylene with bromine was studied over the temperature range 550 to 620°K. The experimental data, derived from the early stages of reaction, were found to be consistent with the following ...
Trace analysis with protons [i.e. proton] and heavy ion activation
(1977)
The capabilities of 12 MeV proton activation were compared with those of reactor neutron and 35 MeV photon activation. A series of biological specimens (plant and animal tissues) were chosen for this study limited to ...
The dissipation of angular momentum in nuclei formed in the reactions of carbon ions with aluminum and nickel and of neon ions with aluminum
(1977)
The amount of angular momentum dissipated during the particle emission and photon emission stages of the deexcitation of the compound nuclei formed in the reactions of 107, 155, and 197 MeV ¹²C ions with ²⁷A1 and with ...
An experimental study of the energy-structure relationships among pentose sugars and some of their derivatives
(1978)
This study seeks to determine, and perhaps explain in terms of structure, some of the thermodynamic properties of a closely related set of carbohydrate compounds. The data sought in this connection are as follows: 1. Heats ...
A mechanistic study of heteroatom di-pi-methane systems containing silicon and nitrogen
(1976)
A series of substituted divinylsilanes: dimethyl-distyryl-(11). Triphenyl-stryrl-(12), diphenyl-distyryl(13), have been prepared for photochemical study. The results of low conversion photolyses of the di-methyl-di-styrylsilane ...
Photochemical studies of a-chymotrypsin and bovine serum albumin containing triplet photosensitizers
(1976)
A new and unusual photochemical method for achieving asymmetric synthesis which uses modified proteins as triplet photosensitizers and prochiral photolabile molecules as substrates is proposed. The modified protein, phenacyl ...
