Theoretical studies of a hydrogen abstraction tool for nanotechnology [PDF]

open access: yes, 1991
In the design of a nanoscale, site-specific hydrogen abstraction tool, the authors suggest the use of an alkynyl radical tip. Using ab initio quantum-chemistry techniques including electron correlation they model the abstraction of hydrogen from ...

A peptide topological template for the dispersion of [60]fullerene in water [PDF]

open access: yes, 2015
Solubilization of [60]fullerene in water is a major challenge for biological and medical applications. To this purpose in this communication we describe for the first time a new dispersing system based on a peptide topological template.
