Search for charmonium and charmoniumlike states in gamma(2S) radiative decays

Olivier Schneider, Remi Léandre Albert Louvot, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Jun Yong Kim, Ji Hyun Kim, Xiao Wang, Jing Li

Using a sample of 158 x 10(6) gamma (2S) events collected with the Belle detector, charmonium and charmoniumlike states with even charge parity are searched for in gamma (2S) radiative decays. No significant chi(cJ) or eta(c) signal is observed, and the fo ...

Bounds on the width, mass difference and other properties of X(3872) -> pi(+)pi(-) J/psi decays

Olivier Schneider, Aurelio Bay, Yiming Li, Remi Léandre Albert Louvot, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Jun Yong Kim, Ji Hyun Kim

We present results from a study of X(3872) -> pi pi J/psi decays produced via exclusive B -> KX(3872) decays. We determine the mass to be M-X(3872) = (3871.85 +/- 0.27(stat) +/- 0.19(syst)) MeV, a 90% confidence level upper limit on the natural width of Ga ...

Passivation of nanocrystalline TiO2 junctions by surface adsorbed phosphinate amphiphiles enhances the photovoltaic performance of dye sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Mingkui Wang, Péter Kalman Péchy, Xuan Li

We report a new class of molecular insulators that electronically passivate the surface of nanocrystalline titania films for high performance dye sensitized solar cells (DSC). Using electrical impedance measurements we demonstrate that co-adsorption of din ...

Interface Modification of Dye-sensitized Solar Cells with Pivalic Acid to Enhance the Open-circuit Voltage

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jun Li, Xuan Li

Pivalic acid (PVA) was used as a new coadsorbent to dyesensitized solar cells (DSCs) to modify the interface between the TiO2 films and electrolyte. The addition of PVA improved the light-to-electricity conversion efficiency of devices by 8% by enhancing t ...

Applications of functionalized ionic liquids

Zhaofu Fei, Dongbin Zhao, Xuan Li

Recent developments of the synthesis and applications of functionalized ionic liqs. (including dual-functionalized ionic liqs.) have been highlighted in this review. Ionic liqs. are attracting attention as alternative solvents in green chem., but as more f ...
