Herein,we report on surface plasmon(SP)-sensitive semitransparent inverted polymer photovoltaic(PV)devices that are based on multilayered material systems consisting of poly(3-hexylthiophene):fullerene-derivative bulk-heterojunction PV layers and thin gold or silver *** demonstrate that these PV devices allow the simultaneous generation of both electrical power and SPs on their anodes for photoexcitation just above the optical absorption edge of the PV layers,resulting not only in attenuated total reflection,but also in attenuated photocurrent generation(APG)under the SP resonance(SPR)***,we also confirm that the biomolecular interaction of biotin–streptavidin on the PV devices can be precisely detected via apparent SPR angle shifts in the APG spectra,even without the need for complex attenuated total reflection *** highlight our view that APG measurements made using these PV devices show great potential for the development of future generations of compact and highly sensitive SPR-based optical sensors.

＜正＞ In this study, the nano-sized layered plates and the hexagonal arrays of one-dimensional channels will be presented for the development of catalyst layers and polyelectrolyte membranes in direct methanol fuel cell （DMFC） applications. The positively-charged layered double hydroxides （LDH） systems were incorporated into the negatively-charged polyelectrolyte polymer in order to change the proton conductivity and diffusion coefficient of DMFC membrane. For different ion exchange capacities and its compositions of LDH, the maximum power density of a single-cell DMFC was measured and correlated with the transport properties of the proton and the methanol through the LDH/Nafion composite membrane systems. In addition, a mesoporous carbon structure based on SBA-15 silica template was used as a cathode catalyst support of platinum in the direct methanol fuel cell. The inverse carbon replica of the template was synthesized by carbonization of sucrose exhibiting a large surface area. Introducing platinum clusters on the carbon support, a large surface area was maintained and the catalytic activation was confirmed by a DMFC single-cell test The mesoporous carbon structure could be an ideal catalyst support for electrode support materials in DMFC providing favorable hosting morphology for the metallic catalyst clusters and interconnected pore network for a facile transport of feeds and products.

HANBIT is a magnetic mirror confinement device. Recent physics experimentshave been mainly focused on identifying discharge characteristics and on getting stable plasmaproduction and operation modes, by using a 500 kW slot antenna system at a fixed RF frequency of 3.5MHz and varying discharge conditions such as fueling rate, RF power, and B-field intensity incentral cell. Two distinct operation modes are found to be very sensitive to the RF power as well asthe ratio of the RF frequency to the ion cyclotron frequency. A MHD interchange mode of m = - 1 isclearly observed and the stabilizing mechanism can be explained by the sideband coupling theory.

在各种化学蒸气沉积生长排列整齐的纳米材料的合成方法中,阳极三氧化二铝(AAO)模板被广泛采用主要由于容易通过电压和阳极氧化时间来控制其孔径.这里,我们表征存在/不存在催化剂时生长在AAO模板上的碳纳米管和氧化物材料的生长机理.我们还研究了在合成密集整齐排列的纳米结构生长过程中氢气的还原效应.实验结果显示AAO模板本身促进Ga2O3VS生长机理,氧化物催化剂氢化还原提高了碳纳米管的生长速率和结晶度.氢化还原中使用AAO模板可以很好地控制排列整齐的纳米材料的直径和密度.

辣椒(Capsicum annuum)是美洲最古老的驯化作物之一,在全世界被广泛种植。本研究对CM334(墨西哥地方品种)进行了全基因组测序和组装(覆盖度为186.6×),同时还对另外两个栽培种和一个野生种分别进行了重测序和从头(de novo)测序。结果表明辣椒基因组大小约为番茄的4倍,辣椒基因组上存在大量gypsy转座子和花椰菜病毒家族元件的积累。结合转录组综合分析认为,辣椒素合成酶基因表达模式的改变及新功能化是导致辣椒素生物合成的原因,研究还发现辣椒与番茄在乙烯合成及果实成熟调控方面存在明显不同的分子模式。辣椒参考基因组的发布为辣椒营养品质和药用价值的改善提供了重要平台。
