By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Amino Acids. According to news reporting originating from Andhra Pradesh, India, by NewsRx correspondents, research stated, "Understanding noncovalent interactions on the surfaces of carbon nanostructures (CNSs) is of fundamental importance and also has implications in nano-and biotechnology. The interactions of aromatic compounds such as benzene, naphthalene, and aromatic amino acids with CNSs of varying diameter, chirality, and curvature were systematically explored by using density functional theory."
Our news editors obtained a quote from the research from the Indian Institute of Chemical Technology, "Planar graphene exhibits stronger binding affinity than curved carbon nanotubes (CNTs), whereas zigzag CNTs appear to show stronger binding affinity than armchair CNTs. For hydrocarbons, there exist two competing modes, namely, pi-pi stacking interactions and CH center dot center dot center dot pi interactions, which bring the aromatic motifs into parallel and perpendicular dispositions with respect to the CNSs, respectively. Our results reveal that pi-pi stacking interactions override CH center dot center dot center dot pi interactions in such cases. However, in the case of aromatic amino acids, pi-pi interactions can exist simultaneously along with a range of other interactions, including CH center dot center dot center dot pi. The polarizability and HOMO energy of the CNSs were found to be the key factors that determine the binding energies."
According to the news editors, the research concluded: "The HOMO-LUMO energy gaps of the CNSs were found to be undisturbed by the noncovalent functionalization of the aromatic molecules."
