While most of the work summarized and analyzed in these references point toward the mechanics of biological macromolecules and biogenic filaments as found in animal tissue, the arguments are helpful in the design of synthetic macromolecules as well.
Biogenic single crystals have been widely demonstrated to incorporate macromolecules to achieve extra damage tolerance, spurring investigations on their synthetic analogs with enhanced mechanical properties as well as the enhancement mechanism(s) behind.
Whereas storage of information in biological systems generally relies on large macromolecules, e.g. DNA and RNA, signaling, that is transduction of information, proceeds to a large extent via biogenic small molecules, metabolites of diverse chemical make-up and biosynthetic history.
The findings were published online by the journal Macromolecules yesterday.
Biogenic ooze, also called biogenic sediment, any pelagic sediment that contains more than 30 percent skeletal material.
"A biogenic origin seems at least as plausible," the scientists added.
In fact, dams are among the largest biogenic landforms produced.
By definition, clays have less than 30 percent biogenic components.
Biogenic sedimentation also increased and fluctuated with the glacial episodes.
Ocean sediments were suddenly less biogenic, and clays became widespread.
