  • Patent number: 9061912
    Abstract: Methods of fabricating graphene nanoribbons include depositing a catalyst layer on a substrate. A masking layer is deposited on the catalyst layer. The masking layer and the catalyst layer are etched to form a structure on the substrate, the structure comprising a portion of the catalyst layer and a portion of the masking layer disposed on the catalyst layer, with sidewalls of the catalyst layer being exposed. A graphene layer is formed on a sidewall of the catalyst layer with a carbon-containing gas.

  • Publication number: 20150125965
    Abstract: Systems and methods for detecting the presence of biomolecules in a sample using biosensors that incorporate resonators which have functionalized surfaces for reacting with target biomolecules. In one embodiment, a device includes a piezoelectric resonator having a functionalized surface configured to react with target molecules, thereby changing the mass and/or charge of the resonator which consequently changes the frequency response of the resonator. The resonator's frequency response after exposure to a sample is compared to a reference, such as the frequency response before exposure to the sample, a stored baseline frequency response or a control resonator's frequency response.

  • Publication number: 20140234702
    Abstract: The loss of sulfur cathode material as a result of polysulfide dissolution causes significant capacity fading in rechargeable lithium/sulfur cells. Embodiments of the invention use a chemical approach to immobilize sulfur and lithium polysulfides via the reactive functional groups on graphene oxide. This approach obtains a uniform and thin (˜tens of nanometers) sulfur coating on graphene oxide sheets by a chemical reaction-deposition strategy and a subsequent low temperature thermal treatment process. Strong interaction between graphene oxide and sulfur or polysulfides demonstrate lithium/sulfur cells with a high reversible capacity of 950-1400 mAh g?1, and stable cycling for more than 50 deep cycles at 0.1 C.

  • Publication number: 20140170483
    Abstract: Multilayer structures with alternating graphene and Si thin films were constructed by a repeated process of filtering liquid-phase exfoliated grapheme film and subsequent coating of amorphous Si film using plasma-enhanced chemical vapor deposition (PECVD) method. The multilayer-structure composite films, fabricated on copper current collectors, can be directly used as anodes for rechargeable lithium-ion batteries (LIBs) without the addition of polymer binders or conductive additives. Fabricated coin-type half cells based on the new anode materials easily achieved a capacity almost four times higher than the theoretical value of graphite even after 30 cycles. These cells also demonstrated improved capacity retention and enhanced rate capability during charge/discharge processes compared to those of pure Si film-based anodes.
