    Conventional functional electrical stimulation aims to restore functional motor activity of patients with disabilities resulting from spinal cord injury or neurological disorders. However, intervention with functional ...
  • Hamill, Michael J.; Jost, Marco; Wong, Cintyu; Bene, Nicholas C.; Drennan, Catherine L.; Elliott, Sean J. (MDPI AG, 2012-12)
    When exposed to known DNA-damaging alkylating agents, Escherichia coli cells increase production of four DNA repair enzymes: Ada, AlkA, AlkB, and AidB. The role of three enzymes (Ada, AlkA, and AlkB) in repairing DNA lesions ...
  • Kane, Margareet M.; Newhouse, Jocelyn M.; Sadoway, Donald Robert; Kane, Margaret M. (Electrochemical Society, 2014-12)
    The variation in the high temperature thermodynamic properties of the Li-Sb system with temperature (425–775ºC) and composition (x[subscript Li] = 0.01–0.75) was determined by electromotive force (emf) measurements in a ...
  • Strobel, Sebastian; Harry, Katherine J.; Duan, Huigao; Yang, Joel K. W.; Manfrinato, Vitor Riseti; Berggren, Karl K. (IOP Publishing, 2011-08)
    We present a new method for developing hydrogen silsesquioxane (HSQ) by using electrical potentials and deionized water. Nested-L test structures with a pitch as small as 9 nm were developed using this electrochemical ...
  • Schindall, Joel E.; Ku, Daniel C.; Signorelli, Riccardo; Kassakian, John G. (Institute of Electrical and Electronics Engineers, 2009-10)
    The structure and behavior of the electrical double-layer capacitor (EDLC) are described. The use of activated carbon electrodes is discussed and the limitations on voltage and accessible surface area are presented. Metrics ...
  • Allanore, Antoine (Elsevier, 2013-05)
    Molten oxide electrolysis (MOE) is a metal extraction process that exhibits an exceptionally high productivity in comparison with other electrowinning techniques. Furthermore, MOE has the ability to generate oxygen as an ...
