Journal ArticleDOI

Douglas A. Davis,Andrew Hamilton,Jinglei Yang,Jinglei Yang,Lee D. Cremar,Dara Van. Gough,Stephanie L. Potisek,Mitchell T. Ong,Paul V. Braun,Todd J. Martínez,Todd J. Martínez,Scott R. White,Jeffrey S. Moore,Nancy R. Sottos +13 more
TL;DR: It is found that pronounced changes in colour and fluorescence emerge with the accumulation of plastic deformation, indicating that in these polymeric materials the transduction of mechanical force into the ring-opening reaction is an activated process.
Journal ArticleDOI
Intrinsic Piezoelectricity in Two-Dimensional Materials
TL;DR: In this article, it was shown that many of the commonly studied two-dimensional monolayer transition metal dichalcogenide (TMDC) nanoscale materials are piezoelectric, unlike their bulk parent crystals.
Journal ArticleDOI
Engineered Piezoelectricity in Graphene
Mitchell T. Ong,Evan J. Reed +1 more
TL;DR: The calculations show that doping a single sheet of graphene with atoms on one side results in the generation of piezoelectricity by breaking inversion symmetry, elucidate a designer piezOElectric phenomenon that has potential to bring dynamical control to nanoscale electromechanical devices.
Journal ArticleDOI
Trapping a Diradical Transition State by Mechanochemical Polymer Extension
Jeremy M. Lenhardt,Mitchell T. Ong,Robert Choe,Christian R. Evenhuis,Todd J. Martínez,Stephen L. Craig +5 more
TL;DR: Mechanochemical activation of the polymer under tension opens the gem-difluorocyclopropanes and traps a 1,3-diradical that is formally a transition state in their stress-free electrocyclic isomerization, leading to the counterintuitive result that the gDFC contracts in response to a transient force of extension.
Journal ArticleDOI
First principles dynamics and minimum energy pathways for mechanochemical ring opening of cyclobutene.
TL;DR: This work uses ab initio steered molecular dynamics to investigate the mechanically induced ring opening of cyclobutene and shows that the dynamical results can be considered in terms of a force-modified potential energy surface (FMPES).
