ABSORPTION CHANGES IN BACTERIAL CHROMATOPHORES. II. A NEWCHLOROPHYLL-LIKE PIGMENT FROM THE OXIDATION OF CHROMATOPHORES FROMRHODOSPIRILLUM RUBRUM (open access)

ABSORPTION CHANGES IN BACTERIAL CHROMATOPHORES. II. A NEWCHLOROPHYLL-LIKE PIGMENT FROM THE OXIDATION OF CHROMATOPHORES FROMRHODOSPIRILLUM RUBRUM

Evidence is presented which points to (at least) two bound forms of bacteriochlorophyll present in chromatophores of Rhodospirillum rubrum, both of them readily converted to unbound bacteriochlorophyll (abs. max. 770 mu) when the chromatophores are extracted with acetone or ethanol. Controlled oxidation of the chromatophores with Ir(IV) or with Zn(II) and ferricyanide preferentially destroys the more strongly absorbing pigment (abs. max. 880 mu) but brings about only a slight decrease in the magnitude of the photoinduced absorption changes at 810 and 792 mu. Such oxidations yield a new pigment, absorbing at 715 mu in the aqueous preparation and, more strongly, at 680-684 mu when the pigment is extracted into organic solvents. This pigment is formed irreversibly and is therefore different from the material formed by photooxidation of chromatophores. Its visible spectrum and the spectrum of the material formed from it by acidification suggest that it is a chlorophyll-like substance, possibly derived from bacteriochlorophyll by (two-electron) oxidation of one of the dihydropyrrole rings to a pyrrole ring. Directions are given for separation of this pigment from other colored compounds present in the oxidation mixtures.

Accurate Nuclear Fuel Burnup Analyses; Ninth Quarterly Progress Report, (December 1963 - February 1964) (open access)

Accurate Nuclear Fuel Burnup Analyses; Ninth Quarterly Progress Report, (December 1963 - February 1964)

The objective of the Accurate Nuclear Fuel Burnup Analyses program is to develop more accurate methods for burnup analysis for general use than the current method of analysis of Ca-137 or Sr-90. The program will require from three to five years of effort.

Advanced reactivity measurement facilities. A description and performance evaluation (open access)

Advanced reactivity measurement facilities. A description and performance evaluation

The Advanced Reactivity Measurement Facilities, ARMF-I and ARMF-II, are nearly identical critical facilities and are used almost exclusively for measuring reactor physics parameters, such as reactor-spectrum cross sections and resonance integral cross sections. They are, therefore, designed to (a) have large statistical weights for fuels and poisons, (b) be mechanically stable enough to produce reproducible reactivity measurements, and (c) have sensitive instrumentation capable of measuring very small reactivities. These facilities are swimming-pool-type reactors having light-water moderated cores made up of platetype fuel elements containing fully enriched U-235. The facilities are located at the National Reactor Testing Station in Idaho near the Materials Testing Reactor (MTR). Being located near the MTR permits measurements on short- lived fission products and transmuted isotopes. By use of the capsule transfer tube connecting the MTR and ARMF canals, a capsule can be transferred from the MTR hydraulic rabbit to the ARMF and prepared for reactivity measurements in 15 minutes. Both ARMF reactors use a servo-controlled regulating rod for reactivity measurements rather than a pile oscillator. The reactivity effect of a capsule placed in the reactor is determined from the resultant regulating rod displacement. In order to make the regulating rod a precise measuring device, its …
