Paramagnetic Faraday rotation with spin-polarized ytterbium atoms

We report observation of the paramagnetic Faraday rotation of spin-polarized ytterbium (Yb) atoms. As the atomic samples, we used an atomic beam, released atoms from a magneto-optical trap (MOT), and trapped atoms in a far-off-resonant trap (FORT). Since Yb is diamagnetic and includes a spin-1/2 isotope, it is an ideal sample for the spin physics, such as quantum non-demolition measurement of spin (spin QND), for example. From the results of the rotation angle, we confirmed that the atoms were almost perfectly polarized.Comment: 8 pages, 20 figure

An Examination of the Oxygen Reduction Reaction on RuO2-based Oxide Coatings Formed on Titanium Substrates

The RuO2-based electrocatalysts were prepared by using a dip-coating method on Ti plate substrates at 400 degrees C. The catalytic activity of the oxide-coated electrodes for the oxygen reduction reaction (ORR) was evaluated by cyclic voltammetry in 0.5 M H2SO4 at 60 degrees C in a stationary state. The examination was focused on the enhancement of the catalytic activity in the reaction by the enlargement of the surface area of the RuO2 coating with the help of lanthunum. The onset potential for the ORR, EORR-0, of the RuO2/Ti electrode showed that the highest value was 0.84 V vs. RHE.ArticleCatalysis Today. 146(1-2):248-252. (2009)journal articl
