| 1 | Resveratrol compares with melatonin in improving in vitro porcine oocyte maturation under heat stress显示文摘Background: Resveratrol, an important phyto-antioxidant commonly found in grapes, mulberry, and other plants,has a variety of functions including anti-aging, anti-cancer and anti-inflammatory activities. In the current study, we investigated the beneficial effects of resveratrol on in vitro porcine oocyte maturation under heat stress(HS). The effect of resveratrol, melatonin and their combination on alleviating HS was compared according to the maturation rate of oocytes and the development competence of embryos after parthenogenetic activation(PA).Results: Supplementation with resveratrol(2.0 μmol/L) not only improved the nuclear maturation but also raised the blastocyst rate of porcine embryos' PA from oocytes that underwent HS by increasing their glutathione(GSH)level, reducing reactive oxygen species(ROS) and up-regulating the expression of Sirtuin 1(SIRT1). It was also found that melatonin(10^(-7)mol/L) and the combination of resveratrol(2.0 μmol/L) plus melatonin(10^(-7)mol/L) exhibited more potent effects than resveratrol alone regarding their protective activities on oocyte maturation under HS.Conclusions: This study compared the efficiencies of resveratrol, melatonin and their combination for protecting porcine oocytes from heat stress. The mechanisms are attributed to the fact that each treatment may have different ability to regulate the synthesis of steroid hormones and the expression of mature related genes. | Yu Li Jing Wang Zhenzhen Zhang Jinyun Yi Changjiu He Feng Wang Xiuzhi Tian Minghui Yang Yukun Song Pingli He Guoshi Liu | 2017 | Journal of Animal Science and Biotechnology2017，8，1： | 7 |
| 2 | The Oxidation State of Sulfur Detected in Na_2O-CaO-SiO_2 Float Glass by X-ray Absorption Near Edge Structure Spectra显示文摘The oxidation state of sulfur is detected in Na2O-CaO-SiO2 float glass by synchrotron radiation X-ray absorption near edge structure (XANES) spectra at the sulfur K edge. The measured spectra show the only presence of S6+ in the Na2O-CaO-SiO2 float glass and the oxidation state of sulfur do not change with the increase of glass depth. It is also found that, after the melt has gone through the molten tin bath, the S6+ is the dominant species, but S2- is also present on both surfaces. It is not certain whether cation bonds to S2- or not, because there are many cations dissolved in the melted tin which makes the spectrum complicated. | 孟政 JIANG Hong HUANG Yourong LI Changjiu WANG Jinzhen CUI Zhu | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，1： | 6 |

| 4 | Micro-nano structured functional coatings deposited by liquid plasma spraying显示文摘Inspired by the micro-nano structure on the surface of biological materials or living organisms,micro-nano structure has been widely investigated in the field of functional coatings.Due to its large specific surface area,porosity,and dual-scale structure,it has recently attracted special attention.The typical fabrication processes of micro-nano structured coatings include sol-gel,hydrothermal synthesis,chemical vapor deposition,etc.This paper presents the main features of a recent deposition and synthesis technique,liquid plasma spraying(LPS).LPS is an important technical improvement of atmospheric plasma spraying.Compared with atmospheric plasma spraying,LPS is more suitable for preparing functional coatings with micro-nano structure.Micro-nano structured coatings are mainly classified into hierarchical-structure and binary-structure.The present study reviews the preparation technology,structural characteristics,functional properties,and potential applications of LPS coatings with a micro-nano structure.The micro-nano structured coatings obtained through tailoring the structure will present excellent performances. | Yuchun HUAN Kaidi WU Changjiu LI Hanlin LIAO Marc DEBLIQUY Chao ZHANG | 2020 | Journal of Advanced Ceramics2020，9，5： | 5 |
| 5 | High-performance quasi-2D perovskite light-emitting diodes: from materials to devices显示文摘Quasi-two-dimensional(quasi-2D)perovskites have attracted extraordinary attention due to their superior semiconducting properties and have emerged as one of the most promising materials for next-generation lightemitting diodes(LEDs).The outstanding optical properties originate from their structural characteristics.In particular,the inherent quantum-well structure endows them with a large exciton binding energy due to the strong dielectricand quantum-confinement effects;the corresponding energy transfer among different n-value species thus results in high photoluminescence quantum yields(PLQYs),particularly at low excitation intensities.The review herein presents an overview of the inherent properties of quasi-2D perovskite materials,the corresponding energy transfer and spectral tunability methodologies for thin films,as well as their application in high-performance LEDs.We then summarize the challenges and potential research directions towards developing high-performance and stable quasi-2D PeLEDs.The review thus provides a systematic and timely summary for the community to deepen the understanding of quasi-2D perovskite materials and resulting LED devices. | Li Zhang Changjiu Sun Tingwei He Yuanzhi Jiang Junli Wei Yanmin Huang Mingjian Yuan | 2021 | Light(Science & Applications)2021，10，4： | 5 |
| 6 | Influence of TiCl_4 treatment on performance of dye-sensitized solar cell assembled with nano-TiO_2 coating deposited by vacuum cold spraying显示文摘Titanium tetrachloride (TiCl4) treatment was employed to TiO2 coating deposited on fluoride-doped tin oxide (FTO) conducting glass and indium oxide doped tin oxide (ITO) conducting glass, respectively. The nano-crystalline TiO2 coating was deposited using a composite powder composed of polyethylene glycol (PEG) and 25 nm TiO2 particles by vacuum cold spraying (VCS) process. A commercial N-719 dye was used to adsorb on the surface of TiO2 coating to prepare TiO2 electrode, which was applied to assemble dye-sensitized solar cell (DSC). The cell performance was measured under simulated solar light at an intensity of 100 mW·cm-2. Results show that with an FTO substrate the DSC composed of a VCS TiO2 electrode untreated by TiCl4 gives a short-circuit current density of 13.1 mA·cm-2 and an open circuit voltage of 0.60 V corresponding to an overall conversion efficiency of 4.4%. It is found that after TiCl4 treatment to the VCS TiO2 electrode with an FTO substrate, the short circuit current density of the cell increases by 31%, the open-circuit voltage increases by 60 mV and a higher conversion yield of 6.5% was obtained. However, when an ITO substrate is used to deposit TiO2 coating by VCS, after TiCl4 treatment, the conversion efficiency of the assembled cell reduces slightly due to corrosion of the conducting layer on the ITO glass by TiCl4. | FAN Shengqiang LI Changjiu YANG Guanjun ZHANG Lingzi | 2006 | Rare Metals2006，25，z1： | 3 |
| 7 | Influence of Deposition Temperature on the Splat Bonding and Mechanical Properties of Plasma-Sprayed Tungsten Coatings显示文摘The mechanical properties of thermally sprayed metallic coatings are limited by the bonding between splats.In this study,tungsten coatings were deposited at different deposition temperatures by controlling the substrate temperature through shrouded plasma spraying.The dependence of the splat bonding and mechanical properties of W coatings on deposition temperature was investigated.The results showed that the apparent porosity of the coatings decreased from 3.2%to 0.3%with the increase of the deposition temperature.The Young's modulus of W coating was significantly increased from 128 to 307 GPa as the deposition temperature increased from room temperature to 800°C.The microhardness of the coatings was less influenced by the deposition temperature.It was found that splat bonding across lamellae was formed when the deposition temperature was higher than 600°C compared to the obvious lamellae interface in the coatings deposited at temperatures lower than 600°C.The results evidently revealed that the mechanical properties of plasma-sprayed W coatings could be controlled through the splat bonding by altering deposition temperature. | Yang Guanjun Kang Xiaohu Li Chengxin Li Changjiu | 2012 | 稀有金属材料与工程2012，41，S1： | 3 |
