Simultaneous Nitrogen-Doping and Reduction of Graphene Oxide
Xiaolin Li, Hailiang Wang, Joshua T. Robinson +3
We develop a simple chemical method to obtain bulk quantities of N-doped, reduced graphene oxide (GO) sheets through thermal annealing of GO in ammonia. X-ray photoelectron spectro…
Preparation of Carbon Nanotube Bioconjugates for Biomedical Applications
Zhuang Liu, Scott Tabakman, Zhuo Chen +1
Biomedical applications of carbon nanotubes have attracted much attention in recent years. Here, we summarize our previously developed protocols for functionalization and bioconjug…
Solvothermal Reduction of Chemically Exfoliated Graphene Sheets
Hailiang Wang, Joshua Tucker Robinson, Xiaolin Li +1
Graphene has attracted much attention due to its interesting properties and potential applications. Chemical exfoliation methods have been developed to make graphene recently, aime…
Emergence of the persistent spin helix in semiconductor quantum wells
Jake D. Koralek, Chris Weber, Joe Orenstein +4
According to Noethers theorem, for every symmetry in nature there is a corresponding conservation law. For example, invariance with respect to spatial translation corresponds to co…
Chemical Self Assembly of Graphene Sheets
Hailiang Wang, Xinran Wang, Xiaolin Li +1
Chemically derived graphene sheets were found to self-assemble onto patterned gold structures via electrostatic interactions between noncovalent functional groups on GS and gold. T…
Phospholipid-Dextran with a Single Coupling Point: a Useful Amphiphile for Functionalization of Nanomaterials
Andrew P. Goodwin, Scott M. Tabakman, Kevin Welsher +3
Nanomaterials hold much promise for biological applications, but they require appropriate functionalization to provide biocompatibility in biological environments. For non-covalent…
