Journal ArticleDOI
Ultrafast Relaxation of Excited Dirac Fermions in Epitaxial Graphene Using Optical Differential Transmission Spectroscopy
Dong Sun,Zong-Kwei Wu,Charles J. Divin,Xuebin Li,Claire Berger,Walt A. de Heer,Phillip N. First,Theodore B. Norris +7 more
TL;DR: In this paper, the authors investigated the ultrafast relaxation dynamics of hot Dirac fermionic quasiparticles in multilayer epitaxial graphene using ultrafast optical differential transmission spectroscopy.
Journal ArticleDOI
Ultrafast hot-carrier-dominated photocurrent in graphene
TL;DR: Time-resolved scanning photocurrent microscopy is used to demonstrate that hot carriers, rather than phonons, dominate energy transport across a tunable graphene p-n junction excited by ultrafast laser pulses.
Journal ArticleDOI
Enhanced cell sorting and manipulation with combined optical tweezer and microfluidic chip technologies
Xiaolin Wang,Shuxun Chen,Marco Kong,Zuankai Wang,Kevin D. Costa,Ronald A. Li,Ronald A. Li,Dong Sun +7 more
TL;DR: A generic single cell manipulation tool that integrates optical tweezers and microfluidic chip technologies for handling small cell population sorting with high accuracy and high recovery rate and purity is reported on.
Journal ArticleDOI
Traumatic brain injury induced cell proliferation in the adult mammalian central nervous system.
TL;DR: The studies showed that the total number of proliferating cells was significantly increased in the injury group for both the SVZ and the hippocampus, and should lead to a new generation of studies aimed at enhancing the neuronal proliferative response.
Journal ArticleDOI
Leader-Follower Formation Control of Multiple Non-holonomic Mobile Robots Incorporating a Receding-horizon Scheme
TL;DR: The receding-horizon scheme is proposed to incorporate into the leader-follower controller to yield a fast convergence rate of the formation tracking errors and to solve the formation problem of multiple non-holonomic mobile robots with a rapid error convergence rate.
