Rice University Research Repository


The Rice Research Repository (R-3) provides access to research produced at Rice University, including theses and dissertations, journal articles, research center publications, datasets, and academic journals. Managed by Fondren Library, R-3 is indexed by Google and Google Scholar, follows best practices for preservation, and provides DOIs to facilitate citation. Woodson Research Center collections, including Rice Images and Documents and the Task Force on Slavery, Segregation, and Racial Injustice, have moved here.

Assembly of planar chiral superlattices from achiral building blocks
(2024-08-27) Jones, Matthew R.; Cheng, Zhihua; Xing, Yuchen; Rice University; United States Patent and Trademark Office
The spontaneous assembly of chiral structures from building blocks that lack chirality is fundamentally important for colloidal chemistry and has implications for the formation of advanced optical materials. Here, we find that purified achiral gold tetrahedron-shaped nanoparticles assemble into two-dimensional superlattices that exhibit planar chirality under a balance of repulsive electrostatic and attractive van der Waals and depletion forces. A model accounting for these interactions shows that the growth of planar structures is kinetically preferred over similar three-dimensional products, explaining their selective formation.

Flash joule heating synthesis method and compositions thereof
(2024-08-06) Tour, James Mitchell; Luong X, Duy; Kittrell, Wilbur Carter; Chen, Weiyin; Rice University; United States Patent and Trademark Office
Methods for the synthesis of graphene, and more particularly the method of synthesizing graphene by flash Joule heating (FJH). Such methods can be used to synthesize turbostratic graphene (including low-defect turbostratic graphene) in bulk quantities. Such methods can further be used to synthesize composite materials and 2D materials.

Facile preparation of carbon nanotube hybrid materials by catalyst solutions
(2024-08-13) Tour, James M.; Salvatierra, Rodrigo Villegas; Zakhidov, Dante; Sha, Junwei; Rice University; United States Patent and Trademark Office
Embodiments of the present disclosure pertain to methods of making a carbon nanotube hybrid material by depositing a catalyst solution onto a carbon-based material, and growing carbon nanotubes on the carbon-based material such that the grown carbon nanotubes become covalently linked to the carbon-based material through carbon-carbon bonds. The catalyst solution includes a metal component (e.g., iron) and a buffer component (e.g., aluminum) that may be in the form of particles. The metal component of the particle may be in the form of a metallic core or metallic oxide core while the buffer component may be on a surface of the metal component in the form of metal or metal oxides. Further embodiments of the present disclosure pertain to the catalytic particles and carbon nanotube hybrid materials. The carbon nanotube hybrid materials of the present disclosure may be incorporated as electrodes (e.g., anodes or cathodes) in energy storage devices.
