Quantum Transport in Graphene Nanonetworks
Andrés Rafael Botello Mendez,Eduardo Cruz-Silva,José M. Romo-Herrera,Florentino López-Urías,Mauricio Terrones,Bobby G. Sumpter,Jean-Christophe Charlier,Vincent Meunier +7 more
TL;DR: In this article, both in-plane conductance of inter-connected graphene nanoribbons and tunneling conductance in out-of-plane intersections are investigated using first-principles calculations based on the density functional theory formalism.
Journal ArticleDOI
Selective tuning of the electronic properties of coaxial nanocables through exohedral doping.
Antonio G. Souza Filho,Vincent Meunier,Mauricio Terrones,Bobby G. Sumpter,Eduardo B. Barros,Federico Villalpando-Paez,Josué Mendes Filho,Yoong Ahm Kim,Hiroyuki Muramatsu,Takuya Hayashi,Morinobu Endo,Mildred S. Dresselhaus +11 more
TL;DR: First-principles calculations elucidate the effects of exohedral doping on the M@S and S@M systems, where a metallic (M) tube is either inside or outside a semiconducting (S) one, and demonstrate that metallic nanotubes are extremely sensitive to doping even when they are inner tubes.
Journal ArticleDOI
Orally Bioavailable Androgen Receptor Degrader, Potential Next-Generation Therapeutic for Enzalutamide-Resistant Prostate Cancer
Suriyan Ponnusamy,Yali He,Dong Jin Hwang,Thirumagal Thiyagarajan,René Houtman,Vera Bocharova,Bobby G. Sumpter,Elias J. Fernandez,Daniel L. Johnson,Ziyun Du,Lawrence M. Pfeffer,Robert H. Getzenberg,Iain J. McEwan,Miller Duane D,Ramesh Narayanan +14 more
TL;DR: Second-generation AR pan antagonist UT-34 exhibits the properties necessary for a next-generation prostate cancer drug and promotes a conformation that is distinct from the LBD-binding competitive antagonist enzalutamide and degrades the AR through the ubiquitin proteasome mechanism.
Journal ArticleDOI
Non-Transition-Metal Catalytic System for N2 Reduction to NH3: A Density Functional Theory Study of Al-Doped Graphene
Yong-Hui Tian,Shuangli Hu,Xiaolan Sheng,Yixiang Duan,Jacek Jakowski,Bobby G. Sumpter,Jingsong Huang +6 more
TL;DR: It is demonstrated by density functional theory that Al-doped graphene is a potential non-TM catalyst to convert N2 to NH3 in the presence of relatively mild proton/electron sources.
Journal ArticleDOI
In Situ Formation of Pyridyl-Functionalized Poly(3-hexylthiophene)s via Quenching of the Grignard Metathesis Polymerization: Toward Ligands for Semiconductor Quantum Dots
W. Michael Kochemba,Deanna L. Pickel,Bobby G. Sumpter,Jihua Chen,S. Michael Kilbey,S. Michael Kilbey +5 more
TL;DR: In this article, a facile one-pot method for preparing 2-pyridyl and 3-polythiophene (P3HTs) with high abundance of monofunctional products is established via an examination of the kinetics of the end-functionalization quenching reaction with lithium chloride complexes of 2- and 3pyridine Grignard reagents.
