We report an in situ measurement of the interaction of an imidazolium-based room temperature ionic liquid with both pure silver and a graphene-over-silver electrode under an applied electrochemical potential. At a negative applied potential, overall

By creating nanoscale pores in a layer of graphene, it could be used as an effective separation membrane due to its chemical and mechanical stability, its flexibility and, most importantly, its one-atom thickness. Theoretical studies have indicated t

We report a mechanistic study of a DNA-mediated vapor phase HF etching of SiO2. The kinetics of SiO2 etching was studied as a function of the reaction temperature, time, and partial pressures of H2O, HF, and 2-propanol. Our results show that DNA loca

Rechargeable Li-ion batteries (LIBs) are currently the dominant power source for portable electronic devices and electric vehicles, and for small-scale stationary energy storage. However, one bottleneck of the anode materials for LIBs is the poor cyc

We report the effect of chemical and physical treatments on the structural stability of DNA origami nanostructures. Our result shows that DNA nanostructure maintains its shape under harsh processing conditions, including thermal annealing up to 200

This paper reports a high-throughput, label-free technique to visualize individual carbon nanotubes (CNTs) on a silicon wafer using a conventional optical microscope. We show that individual CNTs can locally enhance the rate of vapor-phase HF etching

We report a carbon-based, three-dimensional nanofluidic transport membrane that enables gated, or on/off, control of the transport of organic molecular species and metal ions using an applied electrical potential. In the absence of an applied potenti

In this paper we discuss the effect of background pressure and synthesis temperature on the graphene crystal sizes in chemical vapor deposition (CVD) on copper catalyst. For the first time, we quantitatively demonstrate a fundamental role of the back

We report the atmospheric thermal oxidation of chemical vapor deposition (CVD)-grown graphene and its effect on the wrinkles in graphene. Heating CVD-grown single-layer graphene in air at 550 °C leads to the disappearance of the wrinkles and the for
