These are preliminary reports that have not been peer-reviewed. They should not be regarded as conclusive, guide clinical practice/health-related behavior, or be reported in news media as established information. For more information, please see our FAQs.
Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.
To establish an approach for a bulk upscaling of a composit material consisting of calcium carbonate and tunable peptoids we
here combined three distinct approaches to thoroughly access the underlying
kinetic and thermodynamic driving forces for CaCO3 formation on peptoid polymers.
We derived the net interfacial free energy for calcite formation on the
nanosheets and self-assemblage monolayers of the sheets constituent functional
groups (carboxyl, amine and a 1:1 mix) using: nucleation experiments, dynamic
force spectroscopy and theoretical modeling (COSMO-RS). We applied nucleation theory to the results and obtain insight into conditions were we can obtain favorable nucleation conditions on the polymers in a highly controlled manner.
