1Nanostructured SnO_2 photoanode-based dye-sensitized solar cells显示文摘This review focuses on recent developments in the nanostructured SnO2 photoanodes for dye-sensitized solar cells(DSSCs)applications.Carefully designed and fabricated nanostructured SnO2films are advantageous for effective improvement in performance of DSSCs.Nanocrystals can offer a large surface area for dye adsorption;nanowires are able to provide a direct transfer pathway for the rapid collection of photogenerated electrons;the mesoporous,monodisperse beads with a submicrometer-sized diameter ensure a large specific surface area for dye adsorption and simultaneously promote light scattering;the surface modification of SnO2by other oxides may improve the photovoltage and photocurrent,hence resulting in the higher power conversion efficiency of SnO2-based DSSCs.Zhengdao Li Yong Zhou Ruzhong Sun Yan Xiong Haiquan Xie Zhigang Zou 2014Chinese Science Bulletin2014,59,18:3
2THEORETICAL STUDIES ON MICROBUCKLING MODE OF ELASTIC MEMORY COMPOSITES显示文摘Elastic memory composites(EMCs) have great potential applications in future deployable space structures due to their high packaging strain and shape memory characteristics.Microbuckling of compressed fibers is the primary deformation mechanism of such structures to receive a higher packaging strain than that of traditional fiber-reinforced composites.In order to have a better understanding of such deformation mechanism,the microbuckling model of EMC laminates under bending is analyzed firstly.Then the theoretical critical microbuckling parameters are predicted,which are compared with experimental observations and other models.Zhengdao Wang Zhengfa Li Zhiyuan Xiong Linyun Wang(Department of Mechanics,School of Civil Engineering,Beijing Jiaotong University,Beijing 100044,China) 2010Acta Mechanica Solida Sinica2010,23,1:2
3Two birds with one stone:Amine-functionalized MSNs@Eu(OH)CO_(3) nanoprobe for efficient dissolution-enhanced afterglow bioassay显示文摘ABSTRACT The efficient detection of tumor markers is crucial to early cancer diagnosis and monitoring.Here,we propose a unique“two birds with one stone”dissolution-enhanced afterglow bioassay based on amino-functionalized mesoporous SiO2 nanoparticles(MSNs-NH2)encapsulated Eu(OH)CO_(3)nanoprobes.These nanoprobes(i)stably conjugate to the antibody and(ii)are highly soluble in the acidic enhancer solution,and provide a high Eu3+concentration.The released Eu3+ions further activate the photochemical afterglow system to determine the alpha-fetoprotein(AFP)levels in clinical serum samples.Without the use of a real-time excitation source,the interference of autofluorescence and scattering from blood can be avoided.The demonstrated limit of detection(LOD)for AFP was as low as 0.12 ng·mL^(−1).This covalently connected dissolution-enhanced luminescent bioassay(DELBA)and novel afterglow system shows tremendous potential for ultrasensitive and rapid clinical diagnosis.Fuying Zhang Donghao Hu Xianlong Su Zhengdao Hong Wei Feng Ming Xu Fuyou Li 2022Nano Research2022,15,9:1
4Effects of acute salinity stress on the survival and prophenoloxidase system of Exopalaemon carinicauda显示文摘The ridgetail white prawn Exopalaemon carinicauda is a euryhaline shrimp species in the estuarine and coastal areas of China.In this study,survival rates,transcription levels of two prophenoloxidase system-related genes(Ec LGBP and Ecpro PO)and PO activity were determined quantitatively in juvenile and adult E.carinicauda under different salinity levels.The results showed that E.carinicauda juveniles could survive in a wider range of salinity conditions than adults.For juvenile E.carinicauda,the expression levels of Ec LGBP and Ec Pro PO were upregulated in low salinities and showed no significant difference at 20–40,while PO activities in low salinities were higher compared to those in high salinities.For adult E.carinicauda,the expression profiles of Ec LGBP and Ecpro PO had a different trend of up-regulation in salinity stress treatments and no obvious difference was observed in the gene expression levels and PO activity between 30 and 40.The salinity tolerance range of immunity for juvenile and adult E.carinicauda is 20–40 and 30–40,respectively.Qianqian Ge Zhengdao Li Jitao Li Jiajia Wang Jian Li 2020Acta Oceanologica Sinica2020,39,4:0
