    • Designed Synthesis of coaxial SnO₂@carbon hollow nanospheres for highly reversible lithium storage 

      Lou, X.W.; Li, C.M.; Archer, L.A. (WILEY-V C H VERLAG GMBH, 2009-03-25)
      A proof-of-concept structural design is demonstrated for high-capacity lithium-ion batteries anode materials by multistep synthesis of coaxial SnO2@coarbon hollow nanospheres. This material integrates two beneficial features: ...
    • High Resolution Shear Profile Measurements in Entangled Polymers 

      Hayes, K.A.; Buckley, M.R.; Cohen, I.; Archer, L.A. (Physical Review Letters, 2008-11-17)
      We use confocal microscopy and particle image velocimetry to visualize motion of 250-300 nm. fluorescent tracer particles in entangled polymers subject to a rectilinear shear flow. Our results show linear velocity profiles ...
    • An In Situ Method of Creating Metal Oxide-Carbon Composites and Their Application as Anode Material for Lithium-Ion Batteries 

      Yang, Z.; Shen, J.; Archer, L.A. (Royal Society of Chemistry, 2011-06-13)
      Transition metal oxides are actively investigated as anode materials for lithium-ion batteries (LIBs), and their nanocomposites with carbon frequently show better performance in galvanostatic cycling studies, compared to ...
    • Ionic liquid-nanoparticle hybrid electrolytes 

      Lu, Y.; Moganty, S.S.; Schaefer, J.L.; Archer, L.A. (The Royal Society of Chemistry, 2012-01-25)
      e investigate physical and electrochemical properties of a family of organic-inorganic hybrid electrolytes based on the ionic liquid 1-methyl-3-propylimidazolium bis(trifluoromethanesulfone) imide covalently tethered to ...
