The very D-rich IOM compositions, relative to the bulk compositions, cannot be explained by a fully exchangeable IOM with a reasonable value for εorganics-H2O (i.e., <0 ‰). Instead, a two-component IOM model is invoked in which the initial bulk and non-exchangeable IOM have δD = ...

In order to optimize the conditions for the isolation of fibroin from natural silk, two methods for obtaining fibroin solutions were chosen: In an aqueous solution of LiBr and a water–alcohol solution of calcium chloride CaCl2:H2O:C2H5OH (1:8:2). When using the 10% CaCl2 solution in an...
