1Photoanode Activity of ZnO Nanotube Based Dye-Sensitized Solar Cells显示文摘Vertical ZnO nanotube (ZNT) arrays were synthesized onto an indium doped tin oxide (ITO) glass substrate by a simple electrochemical deposition technique followed by a selective etching process. Scanning electron microscopy (SEM) showed formation of well-faceted hexagonal ZNT arrays spreading uniformly over a largearea. X-ray diffraction (XRD) of ZNT layer showed substantially higher intensity for the (0002) diffractionpeak, indicating that the ZnO crystallites were well aligned with their c-axis. Profilometer measurements ofthe ZNT layer showed an average thickness of ~7 μm. Diameter size distribution (DSD) analysis showedthat ZNTs exhibited a narrow diameter size distribution in the range of 65–120 nm and centered at ~75nm. The photoluminescence (PL) spectrum measurement showed violet and blue luminescence peaks thatwere centered at 410 and 480 nm, respectively, indicating the presence of internal defects. Ultra-violet (UV)spectroscopy showed major absorbance peak at ~348 nm, exhibiting an increase in energy gap value of 3.4 eV.By employing the formed ZNTs as the photo-anode for a dye-sensitized solar cell (DSSC), a full-sun conversion efficiency of 1.01% was achieved with a fill factor of 54%. Quantum efficiency studies showed the maximumof incident photon-to-electron conversion efficiency in a visible region located at 520–550 nm range.R. Ranjusha P. Lekha K.R.V. Subramanian V.

2A late Neolithic expansion of Y chromosomal haplogroup O2a1-M95 from east to west显示文摘Y-Chromosomal haplogroup O2a1-M95 的起源和疏开,越过 Austro 分布式东方和南亚的亚洲说带,充分还有待于被理解。各种各样的研究也建议了一个东方印第安人或 O2a1-M95 的东南亚洲起源。我们从印度,老挝,和中国由采样 8748 人处理了古代的问题和 O2a1-M95 的疏开并且从从文学拿的另外的干涉区域把他们比作 3307 件样品。一个总数上的 haplogroup 频率和 Y-STR 数据的分析 2413 个 O2a1-M95 染色体表明老挝样品拥有了 O2a1-M95 的最高的频率(74%与> 0.5 )并且它的祖先的 haplogroups ( O2 *-P31, O *象有 14STR-median haplotype 的样品的一个更高的比例一样的-M175)( 17 取样在里面 14 张人口),深结合时间( 5.7  ± 0.3 Kya )和 consorted O2a1-M95 扩大从 STR 证实了进化。所有这些建议老挝将在学习区域之中带 O2a1-M95 的深古代。在西方的从东方的扩大时间的连续减少:在老挝,在东北印度的 5.2  ± 0.6,和在东方印度的 4.3  ± 0.2 的 5.7  ± 0.3 Kya,建议到西方的晚过时的东方从老挝系 O2a1-M95 传播了。GaneshPrasad Arunkumar Lan-Hai Wei Valampuri John Kavitha Adhikarla Syama Varatharajan Santhakumari Arun Surendra Sathua Raghunath Sahoo R.
