Recently, organic-inorganic halide perovskites with the composition ABX[A = CHNH(MA), NH = CHNH(FA) or cs;B = Pb or Sn;X = Cl, Br, I] have received increasing research attention as light absorbers in solid-state thin-film solar cells..The state-of-the-art high-performing PSC devices routinely incorporated hole-transporting materials(HTMs) as p-type contacts, which play a key role in extraction and collection of the photo-generated holes from the perovskites, and thus minimizing undesired recombination losses at the interfaces. Herein, we successfully applied a facile in-situ solid-state synthesis of conducting polymer poly(3,4-ethylenedioxythiophene)(PEDOT) as a HTM, directly on top of the perovskite layer, in conventional mesoscopic perovskite solar cells(PScs)(n-i-p structure).The fabrication of the PEDOT film only involved a very simple in-situ solid-state polymerisation step from a monomer 2,5-dibromo-3,4-ethylenedioxythiophene(DBEDOT) made from a commercially available and cheap starting *** excellent power conversion efficiency(PCE) is 17.0% measured at 100 mW cm illumination(AM 1.5G).The present finding highlights the potential application of PEDOT made from solid-state polymerisation as a HTM for cost-effective and highly efficient PScs.

虽然李提摩太对大乘佛教的诠释受到他自己的基督教信仰影响,甚至是受到传教使命驱使,但他的进路迥然不同于具殖民色彩的东方学,并且在动机和态度上颇为符合大乘佛教的精神。他在翻译佛典的过程中,没有强调东西方宗教观念之间的差异,反而突出它们的相通之处,希望以此作为基督教与佛教建立合作或友谊的共同基础,而不是使佛教徒皈依基督教。基于他的著述,可以发现他实际上实践了一种后殖民的批评,与殖民势力是对抗的。他的终极目的是全人类的解放,但进路与心态截然不同于那种解救东方人的殖民主义式思维,因为他从来不曾假设西方文明更为高等。就萨义德对东方学或东方主义的批判来说,李提摩太对大乘佛教的响应可以说是一个例外,甚至是反例。

Ethanol modulates sensory information processing in cerebell...

中国神经科学学会第十二届全国学术会议

作者： Mao-Cheng Wu Guang-Jian Zhang De-lai Qiu Key Laboratory of Cellular Function and Pharmacology of Jilin Province Yanbian University

Overdose intake of ethanol can impair cerebellar cortical neurons to integrate and transfer external information, resulting in a dysfunction of cerebellar motor regulation or cerebellar ataxia. We recently investigated the effects of ethanol on sensory stimulation-evoked responses in the cerebellar cortex of urethane-anesthetized mice, by electrophysiological and pharmacological methods. We found that ethanol dosedependently inhibited the facial stimulation evoked field potential responses in cerebellar granule cell layer, whereas ethanol bidirectional modulate the sensory stimulation-evoked responses in molecular layer via GABAA receptor. In vivo patch-clamp recordings showed that ethanol dose-dependently inhibited the facial stimulation-evoked outward currents of cerebellar Purkinje cells（Pcs）. The ethanol-induced inhibition of facial stimulation-evoked outward currents were significantly abrogated by cannabinoid receptor 1（CB1） antagonists and agonist. The ethanol-induced inhibition of facial stimulation-evoked outward currents was prevented by cerebellar surface perfusion of the PKA inhibitors H-89, but not by intracellular administration of the PKA inhibitor PKI. Our present results indicate that ethanol inhibits the facial stimulation-evoked outward currents by activating presynaptic CB1 receptors via the PKA signaling pathway, suggesting that ethanol overdose impairs sensory information processing, at least in part, by inhibiting GABA release from molecular layer interneurons onto Pcs. In addition, ethanol inhibited the spontaneous cs-evoked pause in simple spike firing and in the amplitude of the afterhyperpolarization via activation of CB1 receptors in vivo in mice, suggesting that excessive ethanol intake inhibits climbing fiber–PC synaptic transmission by modulating CB1 receptors in the cerebellar cortex.

对241Am1、4C和137cs 3种核素在PE公司3种磷屏上的放射自显影性能进行了研究,并提出了一种估算曝光时间上限值的方法。从曝光时间角度研究了磷屏对α、β、γ射线的线性特性和饱和特性,结果表明磷屏上无饱和点出现时,3种磷屏都具有良好的线性特性。研究了α、β、γ射线在磷屏上所成影像光强度随时间的衰减性能,表明磷屏的衰减现象是普遍存在的,开始阶段衰减较快,此后衰减速度逐渐变慢。在用磷屏进行放射自显影研究时,一般在曝光后应立即扫描。

巴丹吉林沙漠发育了世界上独一无二的沙漠丘间湖泊群,100多个永久性的丘间湖泊分布于沙漠的东南部。沙漠湖泊岩心是干旱地区重要的气候、环境档案,然而受沙漠湖泊发育极端环境的影响,岩心测年面临很大挑战。本文选择巴丹吉林的沙漠南缘的阿尔吉林和敦德吉林丘间湖泊进行钻探,获取无扰动岩心,利用核素(^(210)Pb_(uns)、^(137)cs)进行测年,并计算其沉积速率。结果表明:1核素(^(210)Pb_(uns)和^(137)cs)测年能够获取巴丹吉林沙漠现代丘间湖泊岩心的可靠年代。2巴丹吉林沙漠丘间湖泊岩心Ar-1的CRS模式测年结果为102±8a,沉积速率分布范围为0.13~0.33cm/a,岩心Dd-1的CRS模式测年结果为123±2a,沉积速率分布范围为0.18~0.70cm/a。3沙漠岩心沉积速率的空间分布具有自沙漠腹地向边缘递增的趋势,^(210)Pb_(uns)-CRS平均沉积速率分布范围为0.16~0.57cm/a,^(137)cs沉积速率分布范围为0.05~0.6cm/a。未来,对于沉积速率空间变化的可能影响因素,如高大沙山的围限、阻挡效应、^(137)cs的分子扩散效应以及古地震影响等应予以关注。

邻避设施兴建或运营可能产生的负外部效应常常引发周边居民的邻避行动。政府与专家倾向于强调公共利好与安全可控,以期对居民进行疏导与解释,但民众对不确定风险的发生与控制怀有一种实践或隐性知识,进而投射于态度或行为。本文聚焦风险经验对邻避认知的塑造机制,从“主体—对象—场域”维度对风险经验进行类分,揭示直接弱经验、间接弱经验与间接强经验的现实表征与归因路径。研究发现:所有经验类型都会推进风险议题的升温,并指向风险监控主体;直接弱经验作用于负面情感标记,间接强经验的独特功能是风险锚定。民众的议题关注、情绪积累、归因归责等要素的叠加,催化了认知解放与风险确定,并可能从认知转向行动。风险经验的分析视角,打破了邻避认知研究以专业知识为准则的知识权威主义,有利于重新审视依违两难和进退维谷的邻避治理困境。

研究了玉米对不同浓度cs+的富集差异,并探讨cs+对玉米幼苗抗氧化指标的影响。结果表明:玉米幼苗中cs+含量均与处理浓度和时间呈显著正相关,根是主要的富集器官,其次为茎;在20mmol/L处理28d后,根的cs+含量分别是茎和叶的1.6和5.1倍;根、茎、叶cs+含量分别是0.5mmol/L处理浓度的16.3、18.0和24.7倍。所有处理时期根、茎、叶转运系数和富集系数与处理时间呈显著正相关,均为茎的转运系数大于叶的转运系数,富集系数由高到低依次为根、茎、叶。对抗氧化生理指标的分析发现,随cs+浓度的增加和处理时间的延长,玉米幼苗POD和CAT活性均表现为先应激性上升后下降的动态变化,丙二醛和过氧化氢含量均呈上升趋势,且与处理时间均呈显著正相关,这表明POD和CAT清除有害过氧化物的能力有限,高浓度时均受到一定程度的抑制,抗氧化体系在一定程度上被破坏。
