Studies on the synthesis and structure of cordycepin monophosphate
(Elsevier, 1963)
Cordycepin monophosphate has been synthesized by two methods. One of these was chemical and involved treatment of cordycepin with cyanoethyl phosphate in the presence of N,N'-dicyclohexylcarbodiimide with subsequent alkaline ...
Determination of small amounts of zirconium--II : Analysis of refractory samples
(Elsevier, 1963-08)
In connection with the determination of small amounts of zirconium in complex samples, procedures have been developed for bringing various types of sample into solution and removing possible interferences, which procedures ...
The acid strength of the amino group as a factor in the transport of amino acids
(Elsevier, 1963)
1. 1. Halogen atoms have been introduced on the [beta]-carbons of amino acids in order to dissociate effects on pKa of the amino group on transport, from effects of the hydrophilic or hydrophobic character of the side ...
Inhibition of protein synthesis in cell-free systems by homocitrullylamino adenosine
(Elsevier, 1963)
Homocitrullylamino adenosine inhibits the incorporation of [14C]amino acids into a hot acid-insoluble form in cell-free systems derived from Escherichia coli and rat liver. The concentration necessary for one-half maximal ...
Infrared spectra and assignments for polyvinyl chloride and deuterated analogs
(John Wiley & Sons, Inc., 1963-08)
Deuterated analogs of polyvinyl chloride (PVC) have been prepared and their infrared spectra analyzed as an aid to the more detailed assignment of bands in the spectrum of PVC. The following deuterated polymers were studied: ...
Radiochemical separation of strontium by amalgam exchange
(Elsevier, 1963-07)
The radiochemical separation of strontium by an amalgam-exchange technique has been critically evaluated with a saturated aqueous solution of potassium chloride as an exchange medium. With an optimised procedure strontium ...

Thermal neutron-activation analysis of titanium using 5[middle dot]8-minute titanium-51 and rapid radiochemical separations
(Elsevier, 1963-01)
A nuclear reactor has been used to determine trace amounts of titanium by neutron-activation analysis in a variety of samples. A 10-min radiochemical separation procedure coupled with gamma-ray spectrometry permitted ...
