Publication number: 20100255984Abstract: Graphene is a single atomic layer of sp2-bonded C atoms densely packed into a two-dimensional honeycomb crystal lattice. A method of forming structurally perfect and defect-free graphene films comprising individual mono crystalline domains with in-plane lateral dimensions of up to 200 ?m or more is presented. This is accomplished by controlling the temperature-dependent solubility of interstitial C of a transition metal substrate having a suitable surface structure. At elevated temperatures, C is incorporated into the bulk at higher concentrations. As the substrate is cooled, a lowering of the interstitial C solubility drives a significant amount of C atoms to the surface where graphene islands nucleate and gradually increase in size with continued cooling. Ru(0001) is selected as a model system and electron microscopy is used to observe graphene growth during cooling from elevated temperatures.Type: ApplicationFiled: April 2, 2010Publication date: October 7, 2010Applicant: Brookhaven Science Associates, LLCInventors: Peter Werner Sutter, Eli Anguelova Sutter

Publication number: 20090194424Abstract: In one embodiment, SWNTs are synthesized from an embedded catalyst in a modified porous anodic alumina (PAA) template. Pd is electrodeposited into the template to form nanowires that grow from an underlying conductive layer beneath the PAA and extend to the initiation sites of the SWNTs within each pore. Individual vertical channels of SWNTs are created, each with a vertical Pd nanowire back contact. Further Pd deposition results in annular Pd nanoparticles that form on portions of SWNTs extending onto the PAA surface. Two-terminal electrical characteristics produce linear I-V relationships, indicating ohmic contact in the devices.Type: ApplicationFiled: February 4, 2008Publication date: August 6, 2009Inventors: AARON D. FRANKLIN, MATTHEW R. MASCHMANN, TIMOTHY S. FISHER, TIMOTHY D. SANDS

Publication number: 20090179181Abstract: A composite material having utility as an anode for lithium ion batteries comprises silicon, a transition metal, a ceramic and an electrically conductive diluent such as carbon. In particular instances, the ceramic is electrically conductive, and may comprise vanadium carbide or tungsten carbide. The transition metal may, in some instances, comprise iron. The material may be fabricated by grinding together a starting mixture of the components, and grinding may be accomplished in a high impact ball milling process, and the grinding step may cause partial alloying of the silicon with the metal and/or carbon. Further disclosed is a method for making the material as well as electrodes which incorporate the material.Type: ApplicationFiled: January 8, 2009Publication date: July 16, 2009Applicant: A123 Systems, Inc.Inventors: Pu Zhang, Suresh Mani, Junqing Ma, Liya Wang, Jun Q.
