Attraction of iodide ions by the free water surface, revealed by simulations with a polarizable force field based on drude oscillators
(2005)Recent theoretical and experimental studies have shown that polarizable anions, such as iodide and bromide, preferentially accumulate close to the surface of electrolyte solutions. This finding is in sharp contrast to the ...

A compact and low-profile metamaterial ring antenna with vertical polarization
(2005)A compact (λ 0/11 footprint) and low-profile (λ 0/28 height) metamaterial ring antenna is proposed using two metamaterial unit cells. Each constituent unit cell consists of negative-refractive-index (NRI) microstrip ...

Comparison of free surface polarization of NiMnSb and Co2 MnSi
(2006)We present a systematic study of the polarization of the transport current from a variety of NiMnSb and Co2 MnSi thin films and bulk material using point contact Andreev reflection spectroscopy. The simple analysis suggests ...

A Directivity-Band-Dependent Triple-Band and Wideband Dual-Polarized Monopole Antenna Loaded with a Via-Free CRLH Unit Cell
(2015)A printed triple-band and wideband dual-polarized meander-line monopole antenna with a single CRLH metamaterial loading is presented. The metamaterial loading improves the impedance matching and causes the proposed antenna ...

Dissecting the stabilization of iodide at the air-water interface into components: A free energy analysis
(2006)Recent experiments and simulations show that large chaotropic anions favor solvation at the water surface, mainly due to induction interactions dominated by ionic polarizabilities. We compare the solvation free-energy ...

Highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor structures
(2004)The highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor (SC) structures was discussed. It was found that the photocurrent was dependent on the relative alignment of the light helicity ...

Linear dynamic polarizability and the absorption spectrum of an exciton in a quantum ring in a magnetic field
(2011)The problem of an electron-hole system interacting through a contact potential and moving in a one-dimensional quantum ring threaded by an Aharonov-Bohm flux is considered, with respect to the system's energetics as well ...

Measurement of J / ψ and ψ (2S) polarization in pp̄ collisions at √s = 1.8 TeV
(2000)We have measured the polarization of J/ψ and ψ(2S) mesons produced in pp̄ collisions at √s = 1.8 TeV, using data collected at the Collider Detector at Fermilab during 1992-1995. The polarization of promptly produced J/ψ ...

Measurement of the lifetime difference between Bs mass eigenstates
(2005)We present measurements of the lifetimes and polarization amplitudes for Bs 0 → J/ψφ and Bd 0 → J/ψK*0 decays. Lifetimes of the heavy and light mass eigenstates in the Bs 0 system are separately measured for the first time ...

Photoinduced inverse spin-Hall effect: Conversion of light-polarization information into electric voltage
(2010)The photoinduced inverse spin-Hall effect was observed in a Pt/GaAs hybrid structure. In the GaAs layer, circularly polarized light generates spin-polarized carriers, inducing a pure spin current into the Pt layer through ...

Production of χc1 and χc2 in pp̄ collisions at √s = 1.8 TeV
(2001)The charmonium system was studied by measuring the relative cross sections of the Xc1 and Xc2 produced in pp collisions at √ s = 1.8 TeV. As a result, the ratio of production cross sections was established.

Spin polarisation and anomalous Hall effect in NiMnSb films
(2004)NiMnSb has attracted a great deal of interest as a spin injector/detector in spintronic devices because it has a Curie temperature of 728 K and is predicted to be half-metallic (100% spin polarized). NiMnSb has been reported ...
