Recent Advances in Chemical Bath Deposition of Electron and Hole Transport Layers for Perovskite Solar Cells and Modules

open access: yesRare Metals, EarlyView.
ABSTRACT The development of high‐efficiency, stable, and scalable perovskite solar cells/perovskite solar modules (PSCs/PSMs) highly depends on the performance and cost‐effectiveness of functional layers such as electron transport layers (ETLs) and hole transport layers (HTLs).

Exploration for effects of acoustic stimulus on movement behavior and HSP70 expression of two kinds of marine crustaceans [PDF]

open access: yes, 2016
水下噪声会潜在的引起海洋生物紧张,分散和掩蔽这些海洋生物重要的声信号,进而对海洋生物的行为和生存造成影响。近几十年来,随着人类社会的不断发展,人们将发展目光投向了占有全球71%面积的海洋。伴随海洋事业的快速发展,海洋工程噪声对海洋生物的影响引起了人们的极大关注。虽然目前已有不少研究成果评估了水下工程噪声对海洋生物的影响,这些噪声包括轮船、打桩、地震勘探以及风电场等水下噪声,表明海洋工程等人为噪声对鱼类以及海洋哺乳动物都将造成了不同程度的影响和伤害。但是 ...

Excellent Comprehensive Electromechanical Properties in PZT‐Based Hard High‐Temperature Piezoceramics

open access: yesRare Metals, EarlyView.
ABSTRACT High‐power piezoelectric ceramics which have a wide operating temperature range are essential for sensor and actuator applications in extreme conditions. However, their development is fundamentally hindered by the inherent trade‐off among key parameters (TC, d33, Qm).

GIS母线温度在线监测技术研究进展

open access: yesGaoya dianqi, 2012
温度在线监测作为电力设备故障诊断的一个重要手段,如果能够用于GIS的状态监测中,将为GIS的正常运行提供进一步的保障。目前,国内外对GIS母线温度在线监测已经做了一些研究,但尚不能达到实用化程度。笔者对当前GIS母线温度在线监测的研究进展进行介绍,主要包括红外辐射探测技术以及红外热诊断技术两种测温手段,同时,对其需进一步探讨的问题进行了分析。由于GIS母线温度在线监测技术还处于研究阶段,为实现其实用化,相关技术还需要进一步完善。笔者对其今后的研究工作进行了总结和展望。

Distribution of 210Po and 210Pb in the Prydz Bay and its adjacent sea areas and their estimate of particulate organic matter export [PDF]

open access: yes, 2016
本研究依托中国第29次南极科学考察航次获得的210Po、210Pb数据,研究了普里兹湾及其邻近海域210Po、210Pb的生物地球化学行为,计算出颗粒有机物的输出通量,揭示了普里兹湾及其邻近海域的颗粒动力学特征。 普里兹湾及其邻近海域D210Po和D210Pb的比活度分别占到T210Po和T210Pb的90%以上,P210Po和P210Pb的份额不足10%。D210Po和D210Pb比活度在陆架区表现为低值,且由陆架向深海逐渐升高,反映了陆架区210Po、210Pb的清除作用强于陆坡及深海区 ...

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China

open access: yesWildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Study on Gene Cloning, Expression and Characterization of Stylicin and Invertebrate Lysozyme in Marsupenaeus japonicus [PDF]

open access: yes, 2014
日本囊对虾(Musupenaeusjaponicus)是我国沿海重要养殖对虾品种,具有非常高的经济价值。近年来日本囊对虾养殖规模受病害影响停滞不前,尤其是白斑综合症病毒(WSSV)等病毒性对虾病对日本囊对虾养殖产业造成严重的经济损失。目前,对虾病毒病的预防和治疗的方法效果均十分有限,而滥用乱用药物易诱发水质污染和药物残留等严重问题。因此,尽快找到环保高效的治疗方法与策略,成为当前海水对虾养殖产业迫切需要解决的重要科学问题。抗菌肽(AMPs)是对虾抵御病原入侵的一类重要的非特异性免疫成分,其抗细菌、真菌 ...
