| 1 | Photocatalytic energy storage ability of TiO_2-WO_3 composite prepared by wet-chemical technique显示文摘TiO2-WO3 hybrid photocatalysts were prepared using wet-chemical technique, and their energy storage performance was characterized by electrochemical galvanostatic method. TiO2 powder was coupled with WO3 powder, which was used as electron pool and the reductive energy could be stored in. As a result, the prepared TiO2-WO3 had good energy storage ability while pure TiO2 showed no capacity and pure WO3 showed quite low performance. The energy storage ability was affected by the crystal structure of WO3 and calcination temperature. The photocatalyst had better capacity when WO3 had low degree of crystallinity, since its loose structure made it easier for electrons and cations to pass through. The photocatalytic energy storage performance was also affected by the molar ratio of TiO2 to WO3. Energy storage capacity was significantly dependent on the composition, reaching the maximum value at TiO2/WO3 1:1 (mol/mol). | Linglin Cao, Jian Yuan, Mingxia Chen, Wenfeng Shangguan Research Center for Combustion and Environment Technology, Shanghai Jiao Tong University, Shanghai 200240, China. | 2010 | Journal of Environmental Sciences2010，22，3： | 5 |
| 2 | Performance and mechanism study for low-temperature SCR of NO with propylene in excess oxygen over Pt/TiO_2 catalyst显示文摘A 0.5 wt.% Pt/TiO2 catalyst was prepared and used for the low-temperature selective catalytic reduction(SCR) of NO with C3 H6 in the presence of excess oxygen.The effects of Pt loading and O2 concentration on Pt/TiO2 catalytic performance for low-temperature SCR were investigated.It was found that optimal Pt loading was 0.5 wt.% and excess O2 favored low-temperature SCR of NOx.The mechanism of low-temperature SCR of NO with C3 H6 was investigated with respect to the behavior of adsorbed species over Pt/TiO2 at 150°C using in situ DRIFTS.The results indicated that surface nitrosyl species(Pt δ+-NO and Ti 3+-NO) and Pt 2+-CO are main reaction intermediates during the interactions of NO,C3 H6 and O2.A simplified NO decomposition mechanism for the low-temperature SCR of NO with C3 H6 was proposed. | Zhixiang Zhang,Mingxia Chen,Zhi Jiang,Wenfeng Shangguan Research Center for Combustion and Environmental Technology,Shanghai Jiao Tong University,Shanghai 200240,China. | 2010 | Journal of Environmental Sciences2010，22，9： | 5 |
| 3 | Correlation of Ferroptosis and Other Types of Cell Death in Neurodegenerative Diseases显示文摘Ferroptosis is defined as an iron-dependent,non-apoptotic cell death pathway,with specific morphological phenotypes and biochemical changes.There is a growing realization that ferroptosis has significant implications for several neurodegenerative diseases.Even though ferroptosis is different from other forms of programmed death such as apoptosis and autophagic death,they involve a number of common protein molecules.This review focuses on current research on ferroptosis and summarizes the cross-talk among ferroptosis,apoptosis,and autophagy that are implicated in neurodegenerative diseases.We hope that this information provides new ideas for understanding the mechanisms and searching for potential therapeutic approaches and prevention of neurodegenerative diseases. | Xiaoting Dang Xuejie Huan Xixun Du Xi Chen Mingxia Bi Chunling Yan Qian Jiao Hong Jiang | 2022 | Neuroscience Bulletin2022，38，8： | 1 |

| 5 | Significantly enhanced superconductivity in monolayer FeSe films on SrTiO_(3)(001) via metallic δ-doping显示文摘Superconductivity transition temperature(T_(c))marks the inception of a macroscopic quantum phase-coherent paired state in fermionic systems.For 2D superconductivity,the paired electrons condense into a coherent superfluid state at Tc,which is usually lower than the pairing temperature,between which intrinsic physics including Berezinskii-Kosterlitz-Thouless transition and pseudogap state are hotly debated.In the case of monolayer FeSe superconducting films on SrTiO_(3)(001),although the pairing temperature(T_(p))is revealed to be 65-83 K by using spectroscopy characterization,the measured zero-resistance temperature(T_(c)^(0))is limited to 20 K.Here,we report significantly enhanced superconductivity in monolayer FeSe films by δ-doping of Eu or Al on SrTiO_(3)(001)surface,in which T_(c)^(0) is enhanced by 12 K with a narrowed transition width ΔT_(c)~8 K,compared with non-doped samples.Using scanning tunneling microscopy/spectroscopy measurements,we demonstrate lowered work function of the δ-doped SrTiO_(3)(001)surface and enlarged superconducting gaps in the monolayer FeSe with improved morphology/electronic homogeneity.Our work provides a practical route to enhance 2D superconductivity by using interface engineering. | Xiaotong Jiao Wenfeng Dong Mingxia Shi Heng Wang Cui Ding Zhongxu Wei Guanming Gong Yanan Li Yuanzhao Li Binjie Zuo Jian Wang Ding Zhang Minghu Pan Lili Wang Qi-Kun Xue | 2024 | National Science Review2024，11，3： | 0 |
| 6 | Aqueous synthesis of bright near-infrared-emitting Zn-Cu-In-Se quantum dots for multiplexed detection of tumor markers显示文摘Aqueous synthesis is a green but challenging pathway to produce cadmium-free,bright,and near-infrared(NIR)emitting quantum dots(QDs).Herein,we develop a straightforward aqueous phase approach to prepare Zn-Cu-In-Se QDs with tunable emission from 630 to 800 nm through varying the molar ratio of Zn and Cu.The ultrasmall nanoparticle size remains nearly fixed(~2.6 nm)when the QD composition is varied,allowing for the effects of composition on the optical properties of QDs to be decoupled from the impact of particle size.By leveraging the off-stoichiometric effect on photoluminescence(PL),Zn-Cu-In-Se QDs with a Zn:Cu molar ratio of 1.0 show a long PL decay lifetime of 211 ns and an absolute photoluminescence quantum yield(PLQY)of 14.2%.The PLQY is further enhanced by overcoating a ZnS shell,reaching up to 25.8%.Based on the bright,biocompatible,and emission-tunable QDs,nanoprobes with targeting capability for multiple tumor markers are further constructed and employed to simultaneously ascertain targets in the cytoplasm and cell membrane.This study provides a green and effective strategy for achieving bright and biocompatible NIR quantum dots for multiplexed biodetection applications. | Hui Liu Peng Cai Kevin J.McHugh Collin F.Perkinson Laishuo Li Shuna Wang Wei Wang Mingxia Jiao Xiliang Luo Lihong Jing | 2022 | Nano Research2022，15，9： | 0 |
| 7 | Generation and Developmental Characteristics of Porcine Tetraploid Embryos and Tetraploid/diploid Chimeric Embryos显示文摘The aim of this study was to optimize electrofusion conditions for generating porcine tetraploid(4n)embryos and produce tetraploid/diploid(4n/2n)chimeric embryos.Different electric feld intensities were tested and 2 direct current(DC)pulses of 0.9 kV/cm for 30 ls was selected as the optimum condition for electrofusion of 2-cell embryos to produce 4n embryos.The fusion rate of 2-cell embryos and the development rate to blastocyst of presumably 4n embryos,reached85.4%and 28.5%,respectively.68.18%of the fused embryos were found to be 4n as demonstrated by fluorescent in situ hybridization(FISH).Although the number of blastomeres in 4n blastocysts was signifcantly lower than in 2n blastocysts(P<0.05),there was no signifcant difference in developmental rates of blastocysts between 2n and 4n embryos(P>0.05),suggesting that the blastocyst forming capacity in 4n embryos is similar to those in 2n embryos.Moreover,4n/2n chimeric embryos were obtained by aggregation of 4n and 2n embryos.We found that the developmental rate and cell number of blastocysts of 4-cell(4n)/4-cell(2n)chimeric embryos were signifcantly higher than those of 2-cell(4n)/4-cell(2n),4-cell(4n)/8-cell(2n),4-cell(4n)/2-cell(2n)chimeric embryos(P<0.05).Consistent with mouse chimeras,the majority of 4n cells contribute to the trophectoderm(TE),while the 2n cells are mainly present in the inner cell mass(ICM)of porcine4n/2n chimeric embryos.Our study established a feasible and effcient approach to produce porcine4n embryos and 4n/2n chimeric embryos. | Wenteng He Qingran Kong Yongqian Shi Bingteng Xie Mingxia Jiao Tianqing Huang Shimeng Guo Kui Hu Zhonghua Liu | 2013 | Genomics, Proteomics & Bioinformatics2013，11，5： | 0 |
