Controlling the Topological Sector of Magnetic Solitons in Exfoliated Cr1/3NbS2 Crystals

Frédéric Mila, Natalia Chepiga, Fengping Li

We investigate manifestations of topological order in monoaxial helimagnet Cr1/3NbS2 by performing transport measurements on ultrathin crystals. Upon sweeping the magnetic field perpendicularly to the helical axis, crystals thicker than one helix pitch (48 ...

Study of chi(cJ) decaying into phi K*(892)(K)over-bar

Qian Wang, Xin Chen, Jiannong Fang, Mingkui Wang, Zhirui Xu, Yi Zhang, Lei Zhang, Yixing Chen, Hua Zhang, Siyuan Wang

Using a data sample of 106 million psi(3686) events collected with the BESIII detector operated at the BEPCII storage ring, we study for the first time the decays chi(cJ) -> phi(KSK +/-)-K-0 pi(-/+) and chi(cJ) -> phi K+K-pi(0) in the E1 radiative transiti ...

Study of the ITER Stray Magnetic Field Effect on the EU 170-GHz2-MW Coaxial Cavity Gyrotron

Stefano Alberti, Jean-Philippe Hogge, Ioannis Pagonakis, Fengping Li

In this paper, the effect of the ITER stray magnetic field (SMF) on the operation of the European gyrotron has been studied. The SMFs include the magnetic field generated by neighboring gyrotrons, the ITER tokamak, and also the field perturbations caused b ...

Proton Pump for O2 Reduction Catalyzed by 5,10,15,20- Tetraphenylporphyrinatocobalt(II)

Hubert Girault, Bin Su, Fengping Li, Raheleh Partovi Nia, Zdenek Samec

The role of 5,10,15,20-tetraphenylporphyrinatocobalt(II) ([Co-(tpp)]) as a catalyst on molecular oxygen (O2) reduction by ferrocene (Fc) and its two derivatives, 1,1’-di-methylferrocene (DFc) and decamethylferrocene (DMFc) at a polarized water¦1,2-dichloro ...

Proton-Coupled Oxygen Reduction at Liquid-Liquid Interfaces Catalyzed by Cobalt Porphine

Hubert Girault, Manuel Alejandro Méndez Agudelo, Imren Hatay, Fengping Li, Zdenek Samec

Cobalt porphine (CoP) dissolved in the organic phase of a biphasic system is used to catalyze O2 reduction by an electron donor, ferrocene (Fc). Using voltammetry at the interface between two immiscible electrolyte solutions (ITIES), it is possible to driv ...

Emerging Web graphics standards and technologies

Daniel Thalmann, Fengping Li

Migrating computer graphics to the Web poses several problems, but with new standards and technology advances, graphics applications can balance latency and bandwidth constraints with image quality. The paper discusses Web graphics standards, distributed v ...
