  • Fardin, Marc-Antoine; Lopez, D.; Croso, J.; Gregoire, G.; Cardoso, O.; McKinley, Gareth H.; Lerouge, S. (American Physical Society, 2010-04)
    We study the dynamics of the Taylor-Couette flow of shear banding wormlike micelles. We focus on the high shear rate branch of the flow curve and show that for sufficiently high Weissenberg numbers, this branch becomes ...
  • Chen, C.-Y.; Wu, Yufei; del Alamo, Jesus A. (American Institute of Physics (AIP), 2015-01)
    We have stressed AlGaN/GaN HEMTs (High Electron Mobility Transistors) under high-power and high-temperature DC conditions that resulted in various levels of device degradation. Following electrical stress, we conducted a ...
  • Yang, Qing; Wang, Rui; Sima, Wenxia; Jiang, Chilong; Lan, Xing; Zahn, Markus (MDPI AG, 2012-03)
    In order to study the flashover mechanism of polluted insulators under AC voltage, a new arc propagation criterion which is based on an arc root voltage gradient is proposed. This criterion can explain the variation of the ...

    Submicrometer fibers of polyaniline (PAni) doped with (+)-camphor-10-sulfonic acid (HCSA) and blended with poly(methyl methacrylate) (PMMA) or poly(ethylene oxide) were electrospun over a range of compositions. Continuous, ...

J. (Nature Publishing Group, 2015-01)
    Controlling the energy flow processes and the associated energy relaxation rates of a light emitter is of fundamental interest and has many applications in the fields of quantum optics, photovoltaics, photodetection, ...
  • Christiano, Paul F.; Kelner, Jonathan Adam; Madry, Aleksander; Spielman, Daniel A.; Teng, Shang-Hua (Association for Computing Machinery, 2011-06)
    We introduce a new approach to computing an approximately maximum s-t flow in a capacitated, undirected graph. This flow is computed by solving a sequence of electrical flow problems. Each electrical flow is given by the ...
  • Tsuk, Michael; Dvorscak, Daniel; Ong, Chin Siong; White, Jacob K. (Institute of Electrical and Electronics Engineers (IEEE), 2009-12)
    rute-force simulation approaches to estimating serial-link bit-error rates (BERs) become computationally intractable for the case when BERs are low and the interconnect electrical response is slow enough to generate ...
  • Desai, Salil P.; Vahey, Michael D.; Voldman, Joel (American Chemical Society (ACS), 2009-02)
    Dielectrophoresis (DEP) has emerged as an important tool for the manipulation of bioparticles ranging from the submicron to the tens of microns in size. Here we show the use of phospholipid vesicle electroformation techniques ...
  • Cai, Yan; Bessette, Jonathan T.; Romagnoli, Marco; Kimerling, Lionel C.; Michel, Jurgen; Camacho-Aguilera, Rodolfo Ernesto; Patel, Neil Sunil (Optical Society of America, 2012-05)
    Electrically pumped lasing from Germanium-on-Silicon pnn heterojunction diode structures is demonstrated. Room temperature multimode laser with 1mW output power is measured. Phosphorous doping in Germanium at a concentration ...
  • Schmidt, Daniel J.; Moskowitz, Joshua Seth; Hammond, Paula T. (American Chemical Society, 2010-11)
    Electrically triggered drug delivery represents an attractive option for actively and remotely controlling the release of a therapeutic from an implantable device (e.g., a “pharmacy-on-a-chip”). Here we report the fabrication ...
  • Huang, Yi; Boriskina, Svetlana V.; Chen, Gang (American Institute of Physics (AIP), 2014-12)
    We explore ways to actively control near-field radiative heat transfer between two surfaces that relies on electrical tuning of phonon modes of ferroelectric materials. Ferroelectrics are widely used for tunable electrical ...
  • Liu, Junwei; Fu, Liang (American Physical Society, 2015-02)
    Based on electronic structure calculations and theoretical analysis, we predict the (111) thin films of the SnTe class of three-dimensional (3D) topological crystalline insulators (TCIs) realize the quantum spin Hall phase ...
  • Steinberg, Hadar; Laloe, Jean-Baptiste; Fatemi, Valla; Moodera, Jagadeesh; Jarillo-Herrero, Pablo (American Physical Society (APS), 2011-12)
    We study coherent electronic transport in charge-density-tunable microdevices patterned from thin films of the topological insulator (TI) Bi[subscript 2]Se[subscript 3]. The devices exhibit pronounced electric field effect, ...
  • Taychatanapat, Thiti; Watanabe, Kenji; Taniguchi, Takashi; Jarillo-Herrero, Pablo (Nature Publishing Group, 2013-02)
    Electrons in a periodic lattice can propagate without scattering for macroscopic distances despite the presence of the non-uniform Coulomb potential due to the nuclei. Such ballistic motion of electrons allows the use of ...
  • Solt, Ken; Van Dort, Christa J.; Chemali, Jessica J.; Taylor, Norman E.; Kenny, Jonathan D.; Brown, Emery N. (Ovid Technologies (Wolters Kluwer) - Lippincott Williams & Wilkins, 2014-08)
    Background:: Methylphenidate or a D1 dopamine receptor agonist induces reanimation (active emergence) from general anesthesia. The authors tested whether electrical stimulation of dopaminergic nuclei also induces reanimation ...
