The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

Since the beginning of the nineteenth century, silicon (Si) has been found in significant
concentrations in plants. Despite the abundant literature which demonstrates its benefits in …

In a previous review of biological and bioinspired silica formation (SV Patwardhan et al.,
Chem. Commun., 2005, 1113 [ref. 1]), we have identified and discussed the roles that …

Relatively little is known about how phytoliths develop and form in the plant. We will
consider the development of phytoliths where silica is deposited in the cell wall and those …

The development of a rapid and non-destructive method to assess purity levels in samples
of biogenic silica prior to geochemical/isotope analysis remains a key objective in improving …

In contrast to many other stable isotopes of the elements discussed in this book, those of
silicon are not strictly speaking “Non-Traditional Stable Isotopes” because they have been …

This paper provides an overview of stable isotope analysis (H, C, N, O, Si) of the macro-and
microscopic remains from aquatic organisms found in lake sediment records and their …

Several techniques have been introduced in the last decades for the dehydration and
release of O2 from biogenic silica (opal-A) for oxygen-isotope analysis. However, only one …

Rain-fed cultivation in drylands—especially in arid and hyper-arid areas—is often
considered to play a minor role in human subsistence. Drawing upon the results of …

Seasonal variations in hydrology and Si cycling in the Nile Basin were investigated using
stable-isotope (H, O, and Si) compositions and dissolved Si (DSi) concentrations of surface …
