Search For Neutral Higgs Bosons In Multi-B-Jet Events In Pp Collisions At √S = 1.96 Tev, V. M. Abazov, Kenneth A. Bloom, Gregory Snow, D0 Collaboration Nov 2008

Search For Neutral Higgs Bosons In Multi-B-Jet Events In Pp Collisions At √S = 1.96 Tev, V. M. Abazov, Kenneth A. Bloom, Gregory Snow, D0 Collaboration

Kenneth Bloom Publications

Data recorded by the D0 experiment at the Fermilab Tevatron Collider are analyzed to search for neutral Higgs bosons produced in association with b quarks. This production mode can be enhanced in the minimal supersymmetric standard model (MSSM). The search is performed in the three b quark channel using multijet triggered events corresponding to an integrated luminosity of 1 fb-1. No statistically significant excess of events with respect to the predicted background is observed and limits are set in the MSSM parameter space.

Primary Study Of Tiron As Active Materials For The Redox Flow Battery, Yan Xu, Yue-Hua Wen, Jie Cheng, Yu-Sheng Yang, Zi-Li Xie

Journal of Electrochemistry

Effects of solution pH on the electrochemical behavior of tiron(sodium 4,5-dihydroxy-1,3-benzendisulfonic) couple(on a graphite electrode) were studied by cyclic voltammetry in aqueous solutions.It is shown that at pH<4,tiron exhibited a redox process at a relatively high potential with a good reversibility.A redox flow battery was formed employing tiron as the positive active species and V(III)/V(II) as the negative redox couple.In sulfuric acid medium,the coulombic efficiency of the tiron-V redox flow cell was more than 90% with a good cycle life.The decay in the cycle performance was minimal.Therefore,the feasibility of tiron as active materials for redox flow battery application is demonstrated.

Combustion Product Characterization Of The Iron-Heated Powders In Thermal Batteries, Jin Chong, Xue-Ping Gao, Ji-Qiang Wang

Journal of Electrochemistry

The combustion products of thermal battery used iron-heated powders have been studied.It is identified by X-ray diffraction (XRD) analysis that the main compositions of the combustion products are Fe, FeO and KCl. The transmission electron microscopy(TEM) shows a typical core-shell structure with un-reacted Fe particle core coated by FeO shell with a shell thickness of around 200 nm. The combusted iron-heated powders exhibit no metal property, which is contrast to previous assumption. Further measurement indicates that at the ambient temperature the combustion products show semiconductor property of the p-type with conductivity in the order of 103 S·cm-1, which …

Studies Of Surface Diffusion In Pemfc Electrodes, Jiang-Shui Luo, Jian Chen, Bao-Lian Yi, Chuan-Sin Cha, Hua-Min Zhang

Journal of Electrochemistry

A PEMFC electrode consisting of dual-layer catalyst layer(CL) was fabricated in this work. The outer CL was Nafion-free,while the inner CL was Nafion-bonded. The effects of Pt/C catalyst in the outer CL that did not contact with Nafion on the current generation in PEMFC electrodes were investigated. Cyclic voltammetric studies indicated that the Pt/C catalyst in the outer CL without direct contact with Nafion was still electrochemically active in taking part in the adsorption/desorption of hydrogen and the electrochemical oxidation/reduction of the oxygen-containing species occurring at the interface of "Pt/Nafion" in the inner CL. The polarization curves showed that the …

Effect Of Ch2Cl2 On The Redox Behavior Of Ferrocene In Ionic Liquid Bmimpf6, Wei-Wei Ji, Li-Qun Xu, Dong-Mei Li, Rong Wang, Xia-Qin Wu, Zong-Rang Zhang

Journal of Electrochemistry

The effects of CH2Cl2 on the room temperature redox behaviors of ferrocene in ionic liquid,BmimPF6,were studied by cyclic voltammetry and AC Impedance.The results suggested that the presence of CH2Cl2,accelerated the dissociation of ionic liquid,leading to lower viscosity and larger ionic conductovity,hence,the diffusions of ferrocence in BmimPF6 were enhanced and the peak currents of redox reactions were increased.The changes in the double-layer structure at the electrode interface resulted in larger capacitance,which reduced the electrode recution resistances,accordirgly,the reaction kinetics of ferrocene were enhanced.

Solutions In Folded Geometries, And Associated Cloaking Due To Anomalous Resonance, Graeme W. Milton, Nicolae-Alexandru P. Nicorovici, Ross C. Mcphedran, Kirill Cherednichenko, Zubin Jacob

Birck and NCN Publications

Solutions for the fields in a coated cylinder where the core radius is bigger than the shell radius are seemingly unphysical, but can be given a physical meaning if one transforms to an equivalent problem by unfolding the geometry. In particular, the unfolded material can act as an impedance matched hyperlens, and as the loss in the lens goes to zero finite collections of polarizable line dipoles lying within a critical region surrounding the hyperlens are shown to be cloaked having vanishingly small dipole moments. This cloaking, which occurs both in the folded geometry and the equivalent unfolded one, is …

Transformation Optics: Approaching Broadband Electromagnetic Cloaking, Alexander V. Kildishev, W Cai, U K. Chettiar, V. M. Shalaev

Birck and NCN Publications

An approach to broadband cloaking of light waves is analysed for a simplified case of a scaling transformation for a general cylindrical coordinate system. The proposed approach requires metamaterials with specifically engineered dispersion. The restriction on the signs of gradients in the dispersion dependencies of the dielectric permittivity and the magnetic permeability for different operational wavelengths is revealed and is shown to cause difficulties unless additional gain-assisted compensation for losses or electromagnetically induced transparency is introduced in the cloaking system.
