作者： Benjamin F Katz Doron S Stember Harris M Nagler Beth Israel Medical Center and the albert Einstein College of Medicine of Yeshiva University 1300 Morris Park Avenue Bronx NY 10461 USA

In a recently published article in Asian Journal of Andrology, Ho et al.1 examine prevalence, attitudes, and treatment patterns related to sexual dysfunction in Asia and contrast them with those of Western society. They highlight the relative paucity of data with respect to erectile dysfunction （ED）, premature ejaculation, and hypogonadism in the Asian population.

Remarkable recent demonstrations of ultra-low-loss inhibited-coupling(1C)hollow-core photonic-crystal fibres(HCPCFs)established them as serious candidates for next-generation long-haul fibre optics systems.A hindrance to this prospect and also to short-haul applications such as micromachining,where stable and high-quality beam delivery is needed,is the difficulty in designing and fabricating an IC-guiding fibre that combines ultra-low loss,truly robust single-modeness,and polarisation-maintaining *** design solutions proposed to date require a trade-off between low loss and truly ***,we propose a novel IC-HCPCF for achieving low-loss and effective single-mode *** fibre is endowed with a hybrid cladding composed of a Kagome-tubular lattice(HKT).This new concept of a microstructured cladding allows us to significantly reduce the confinement loss and,at the same time,preserve truly robust single-mode *** results show an HKT-IC-HCPCF with a minimum loss of 1.6dB/km at 1050 nm and a higher-order mode extinction ratio as high as 47.0 dB for a 10 m long *** robustness of the fibre single-modeness is tested by moving the fibre and varying the coupling *** design proposed herein opens a new route for the development of HCPCFs that combine robust ultra-low-loss transmission and single-mode beam delivery and provides new insight into IC guidance.

An optical device to homogenize a laser beam

Chinese Optics Letters 2005年第12期3卷 698-700页

作者：李重光李俊昌 Agèns Delmas Institute of Applied Laser Kunming University of Science and TechnologyKunming 650093 CETHIL UMR 5008 INSA de Lyon Batiment S.Carnot 20 Avenue Albert Einstein 69621 Villeurbanne CedexFrance

Based on segmentation-recombination principle, a specific optical device is designed to homogenize a highpower CO2 laser beam which is used as a heating source. A model is developed to simulate the intensity distribution of converted laser beam. The results show that the theoretical simulation is consistent with experimental record. The uniformity of converted beam spot is discussed. After modifying the optical parameters of current device, a new optical system is given, through which the uniformity of shaped beam spot is improved remarkably.

(La0.8A0.2)MnO3(A=Sr,K) perovskite catalysts for NO and C10H22 oxidation and selective reduction of NO by C(10)H(22)

引用

催化学报 2014年第8期35卷 1299-1304页

作者： Anne Giroir-Fendler Sonia Gil Alexandre Baylet Lyon University Lyon F-69003 Lyon 1 University CNRS UMR 5256 IRCEL YON Albert Einstein Avenue 2 Villeurbanne F-69622 France

In this work, we studied the catalytic activity of LaMnO3 and(La0.8A0.2)MnO3(A = Sr, K) perovskite catalysts for oxidation of NO and C10H22 and selective reduction of NO by C10H22. The catalytic per‐formances of these perovskites were compared with that of a 2 wt% Pt/SiO2 catalyst. The La site substitution increased the catalytic properties for NO or C10H22 oxidation compared with the non‐substituted LaMnO3 sample. For the most efficient perovskite catalyst,(La0.8Sr0.2)MnO3, the results showed the presence of two temperature domains for NO adsorption:(1) a domain corre‐sponding to weakly adsorbed NO, desorbing at temperatures lower than 270 °C and(2) a second domain corresponding to NO adsorbed on the surface as nitrate species, desorbing at temperatures higher than 330 °C. For the Sr‐substituted perovskite, the maximum NO2 yield of 80% was observed in the intermediate temperature domain (around 285 °C). In the reactant mixture of NO/C10H22/O2/H2O/He,(La0.8Sr0.2)MnO3 perovskite showed better performance than the 2 wt% Pt/SiO2 catalyst: NO2 yields reaching 50% and 36% at 290 and 370 °C, respectively. This activity improvement was found to be because of atomic scale interactions between the A and B active sites, Sr2+ cation and Mn4+/Mn3+ redox couple. Thus,(La0.8Sr0.2)MnO3 perovskite could be an alternative free noble metal catalyst for exhaust gas after treatment.
