Journal ArticleDOI
The influence of curvature on domain distribution in binary mixture membranes
Wei Li,Jan-Michael Y. Carrillo,John Katsaras,John Katsaras,Bobby G. Sumpter,Rana Ashkar,Rajeev Kumar +6 more
TL;DR: It is demonstrated that domain distribution strongly depends on local topography and further highlights the collective effects that thermodynamic forces have on the morphological behavior of membranes.
Journal ArticleDOI
On the morphological behavior of ABC miktoarm stars containing poly(cis 1,4‐isoprene), poly(styrene), and poly(2‐vinylpyridine)
Sergey Chernyy,Jyoti P. Mahalik,Rajeev Kumar,Jacob J. K. Kirkensgaard,Matthias M. L. Arras,Hyeyoung Kim,Lars Schulte,Sokol Ndoni,Gregory S. Smith,Kell Mortensen,Bobby G. Sumpter,Thomas P. Russell,Kristoffer Almdal +12 more
TL;DR: In this article, the effects of the microstructure of the I arm on the Flory-Huggins parameter between I and V arms were taken into account in a qualitative manner.
Journal ArticleDOI
Polymer-blend microparticles: Anew approach to nanoscale composites with tunable properties
TL;DR: In this paper, the problem of phase separation from bulk immiscible componen t s in solut ion often poses a significant barr ier to producing many commercial and scientifically relevant homogeneous polymer blends.
Journal ArticleDOI
Quantum theory of electronic excitation and sputtering by transmission electron microscopy.
Anthony Yoshimura,Michael Lamparski,Joel Giedt,David B. Lingerfelt,Jacek Jakowski,Panchapakesan Ganesh,Bobby G. Sumpter,Vincent Meunier +7 more
TL;DR: In this paper , the probability of beam-induced electronic excitations by coupling quantum electrodynamics (QED) scattering amplitudes to density functional theory (DFT) single-particle orbitals is calculated.
Journal ArticleDOI
A Novel Dynamic Polymer Synthesis via Chlorinated Solvent Quenched Depolymerization
Jiadeng Zhu,Sheng Zhao,Jiancheng Luo,Wei Niu,Joshua Damron,Zhen Hui Zhang,Md. Anisur Rahman,Mark A. Arnould,Tomonori Saito,Rigoberto C. Advincula,Alexei P. Sokolov,Bobby G. Sumpter,Peng Cao +12 more
TL;DR: Zhang et al. as discussed by the authors reported a novel organic solvent quenched polymer synthesis using the natural molecule thioctic acid (TA), which has both a dynamic disulfide bond and carboxylic acid.
