Diffusion-driven Fractionation of Iron Isotopes in Oxidized and Reduced Silicate
Introduction: Chemical diffusion of cations and atoms in silicates and metals can promote large isotopic fractionation [1]. An empirical formula relates the diffusion coefficients of two isotopes of an element to their mass ratios through D 1 /D 2 =(m 2 /m 1)
متن کاملFractionation and Determination of Some Structural Properties of Persian Gum
ABSTRACT: In the present study, Persian gum, an exudate gum which secrets from the mountain almond tree (Amygdalus scoparia Spach) from two different regions is evaluated by means of chemical and instrumental analysis (fractionated by solving in water and alkaline solutions at 0.1, 0.5 and 1 M and also Smith degradation) using HPLC, 1H–NMR and 13C–NMR spectroscopy’s. The total sugar and uronic ...

متن کاملCharacterization of oxidized tannins: comparison of depolymerization methods, asymmetric flow field-flow fractionation and small-angle X-ray scattering.
Condensed tannins are a major class of plant polyphenols. They play an important part in the colour and taste of foods and beverages. Due to their chemical reactivity, tannins are not stable once extracted from plants. A number of chemical reactions can take place, leading to structural changes of the native structures to give so-called derived tannins and pigments. This paper compares results ...
متن کاملTumour radiobiology beyond fractionation
Historically it has been shown repeatedly that single high doses of radiation do not allow a therapeutic differential between tumor and critical normal tissues but dose fractionation does. The purpose of conventional dose fractionation is to increase dose to the tumor while preserving normal tissue function. Tumors are generally irradiated with 2Gy dose per fraction delivered daily to a more or...
