1Studies on electroless Ni-P-Cr_2O_3 and Ni-P-SiO_2 composite coatings显示文摘本文对化学镀镍及化学镀镍磷基质中SiO2与Cr2O3的共沉积进行了研究。微粒在不断生长的膜层中共沉积引起了新的化学复合镀层的出现,这些复合镀层许多都具有优异的耐磨及耐蚀性能。通过选取镀层合金/复合微粒/金属基体的组分可改进镀层,获得所需的性能,以满足特别的需求。在对这些复合镀层的应用需求正在迫近与增长的同时,其市场正在迅速扩张。本文开发出了一种合适的复合化学镀镍液,并通过维氏硬度法对化学复合镀镍层进行了表征。采用动电位极化及交流阻抗法测定了镀层的Taber耐磨性能及耐蚀性能。采用SEM及XRD对复合镀层的表面形貌进行了分析。KARTHIKEYAN S SRINIVASAN K N VASUDEVAN T JOHN S 2007电镀与涂饰2007,26,1:15

3Endothelial cell-derived GABA signaling modulates neuronal migration and postnatal behavior显示文摘服的外皮为集成是必要的并且为大多数行为被要求的信息处理。当神经原从室的地区连续地移居联合进特定的外皮的层时,服的外皮的精致地精确的 laminar 组织在胚胎的开发期间产生。当时指南为设计神经原移植责骂的光线的神经胶质行为, pre-formed 脉管的网络为 GABAergic interneuron 移植提供支持和指导暗示。这研究提供新奇概念、机械学的卓见进 vascular-neuronal 相互作用的这个范例,揭示伽马氨基丁酸并且它经由胚胎的前脑 endothelial 房间的调停受体的发信号的新机制。与二个新 endothelial 房间的使用,特定的有条件的老鼠 GABA 小径当模特儿(Gabrb3 Tie2-Cre 和 Vgat 我们显示出的 Tie2-Cre ), 从 endothelial 房间的伽马氨基丁酸版本的那部分或完全的损失在 embryogenesis 期间导致脉管的缺点并且损害长途的移植并且外皮的 interneurons 放。使不安的 endothelial 的下游的效果导出房间的伽马氨基丁酸发信号是批评的,导致上次修改到外皮的电路和坚持的行为的赤字。而且,我们说明在支持他们血大脑障碍性质的迁居, angiogenesis 和获得的前脑 endothelial 房间发信号的伽马氨基丁酸的激活的新机制。我们的调查结果揭开并且阐明在从表明小径的古典 neuronal 伽马氨基丁酸是不同的并且在 neuropsychiatric 疾病的病原学和 pathophysiology 上打开新灯的 CNS 表明小径的新奇 endothelial 伽马氨基丁酸例如孤独性光谱混乱,癫痫,焦虑,消沉和精神分裂症。Suyan Li Peeyush Kumar Sampada Joshee Timo Kirschstein Sivan Subburaju Jahan S Khalili Jonas Kloepper Chuang Du Abdallah Elkhal Gabor Szabo Rakesh K Jain Rudiger Kohling Anju Vasudevan 2018Cell Research2018,28,2:3
4Structural and luminescence enhancement properties of Eu^(3+)/Ag nanocrystallites doped SiO_2-TiO_2 matrices显示文摘We reported here the structural and optical characterisation of silver nanocrystallites/Eu3+ :SiO2-TiO2 matrices synthesised through sol-gel route. Structural characterisations were done by using energy dispersive spectroscopy (EDX), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), atomic force microscope (AFM) and transmission electron microscopy (TEM) measurements and optical characterisations were performed by absorption and emission spectroscopy. The TEM and XRD measurements confirmed the presence of nanocrystals. A broad absorption band was observed due to surface plasmon resonance of silver nanocrystals. The effect of silver nanocrystals on the emission spectrum of Eu3+ doped SiO2-TiO2 matrices was discussed. An attempt was made to explain this fluorescence enhancement by invoking phenomena such as energy transfer, asymmetry ratio, surface plasmon, surface roughness, crystallinity and grain boundary. Our analysis, based on the experimental results, suggested that all the phenomena except crystallinity and grain boundary had favourable effects on fluorescence enhancement. We also estimated the relevant parameters associated with the phenomena that affected the fluorescence emission from the Eu3+ ions in the matrix. It was seen that the theoretical estimate of fluorescence enhancement agreed well with the experimental estimate.Arun Kumar K V Revathy K P Prathibha Vasudevan Sunil Thomas Biju P R Unnikrishnan N V 2013Journal of Rare Earths2013,31,5:2
