| 2 | Enhanced chemical trapping and catalytic conversion of polysulfides by diatomite/MXene hybrid interlayer for stable Li-S batteries显示文摘Lithium-Sulfur (Li-S) batteries with high theoretical energy density are promising energy storage systems in the next decades, while the lithium polysulfides (LiPSs) shuttling caused by the sluggish sulfur redox reaction severely lowers the practical performance. The use of interlayer between the cathode and separator has been widely investigated to physically or chemically block the LiPSs, while the introduction of catalytic materials is a more effective strategy to accelerate the conversion of LiPSs. MXene with rich surface chemistry has shown its potential for facilitating the catalytic conversion, however, the aggregation of MXene sheets usually leads to the loss of the catalytic active sites. Herein, we report a diatomite/MXene (DE/MX) hybrid material as the bifunctional interlayer for improving the adsorption/conversion of LiPSs in Li-S batteries. The diatomite with porous structure and rich silica-hydroxyl functional groups could trap LiPSs effectively, while prevent the aggregation of MXene. The DE/MX based interlayer showed bifunctions of enhancing the chemical adsorption and promoting the conversion of LiPSs. The Li-S batteries with the DE/MX interlayer delivered an improved cycling stability with a low capacity decay of 0.059% per cycle over 1000 cycles at 1.0 C. Moreover, stable 200 cycles can be realized with a high sulfur loading electrode up to 6.0 mg cm^(−2). This work provides an effective strategy to construct bifunctional interlayers for hindering the shuttling of LiPSs and boosting the practical application of Li-S batteries. | Zehui Fan Chen Zhang Wuxing Hua Huan Li Yan Jiao Jingyi Xia Chuan-Nan Geng Rongwei Meng Yingxin Liu Quanjun Tang Ziyang Lu Tongxin Shang Guowei Ling Quan-Hong Yang | 2021 | Journal of Energy Chemistry2021，30，11： | 1 |
| 3 | Improved empirical DC I-V model for 4H-SiC MESFETs显示文摘A novel empirical large signal direct current(DC) I-V model is presented consider-ing the high saturation voltage,high pinch-off voltage,and wide operational range of drain voltage for 4H-SiC MESFETs.A comparison of the presented model with Statz,Materka,Curtice-Cubic,and recently reported 4H-SiC MESFET large signal I-V models is made through the Levenberg-Marquardt method for fitting in nonlin-ear regression.The results show that the new model has the advantages of high accuracy,easily making initial value and robustness over other models.The more accurate results are obtained by the improved channel modulation and saturation voltage coefficient when the device is operated in the sub-threshold and near pinch-off region.In addition the new model can be implemented to CAD tools di-rectly,using for design of 4H-SiC MESFET based RF&MW circuit,particularly MMIC(microwave monolithic integrate circuit). | CAO QuanJun ZHANG YiMen ZHANG YuMing LV HongLiang WANG YueHu TANG XiaoYan GUO Hui | 2008 | Science in China(Series F)2008，51，8： | 1 |
| 4 | Generation of multi-gene knockout rabbits using the Cas9/gRNA system显示文摘The prokaryotic clustered regularly interspaced short palindromic repeat(CRISPR)-associated system(Cas)is a simple,robust and efficient technique for gene targeting in model organisms such as zebrafish,mice and rats.In this report,we applied CRISPR technology to rabbits by microinjection of Cas9 mRNA and guided RNA(gRNA)into the cytoplasm of pronuclear-stage embryos.We achieved biallelic gene knockout(KO)rabbits by injection of 1 gene(IL2rg)or 2 gene(IL2rg and RAG1)Cas9 mRNA and gRNA with an efficiency of 100%.We also tested the efficiency of multiple gene KOs in early rabbit embryos and found that the efficiency of simultaneous gene mutation on target sites is as high as 100%for 3 genes(IL2rg,RAG1 and RAG2)and 33.3%for 5 genes(IL2rg,RAG1,RAG2,TIKI1 and ALB).Our results demonstrate that the Cas9/gRNA system is a highly efficient and fast tool not only for single-gene editing but also for multi-gene editing in rabbits. | Quanmei Yan Quanjun Zhang Huaqiang Yang Qingjian Zou Chengcheng Tang Nana Fan Liangxue Lai | 2014 | Cell Regeneration2014，3，1： | 0 |
| 5 | Generation of pigs with humanized type Ⅱ collagen by precise human COL2A1 gene knock-in显示文摘Osteoarthritis(OA)is the most common chronic disease,characterized by progressive cartilage breakdown,subchondral bone sclerosis,and aberrant bone outgrowth(Yucesoy et al.,2015;Hussain et al.,2016).OA is one of the leading causes of cartilage damage.Patients with severe cartilage damage require transplantation of articular cartilage to improve their quality of life.Type Ⅱ collagen is a major component of articular cartilage and intervertebral discs and plays an important role in the structure and strength of connective tissues that support muscles and joints(Byers,1994). | Ting Lan Yuling Zheng Yangyang Suo Yuhui Wei Hui Shi Quanmei Yan Zhenpeng Zhuang Huangyao Chen Quanjun Zhang Nana Fan Yu Zhao Zhen Ouyang Chengdan Lai Zhaoming Liu Jizeng Zhou Chengcheng Tang Nam-Hyung Kim Qingjian Zou Xiaomin Wang | 2023 | Journal of Genetics and Genomics2023，50，3： | 0 |
| 6 | Solution-based Preparation of High Sulfur Content Sulfur/Graphene Cathode Material for Li-S Battery显示文摘Practical Li-sulfur batteries require the high sulfur loading cathode to meet the large-capacity power demand of electrical equipment.However,the sulfur content in cathode materials is usually unsatisfactory due to the excessive use of carbon for improving the conductivity.Traditional cathode fabrication strategies can hardly realize both high sulfur content and homogeneous sulfur distribution without aggregation.Herein,we designed a cathode material with ultrahigh sulfur content of 88%(mass fraction)by uniformly distributing the water dispersible sulfur nanoparticles on three-dimensionally conductive graphene framework.The water processable fabrication can maximize the homogeneous contact between sulfur nanoparticles and graphene,improving the utilization of the interconnected conductive surface.The obtained cathode material showed a capacity of 500 mA·h/g after 500 cycles at 2.0 A/g with an areal loading of 2 mg/cm2.This strategy provides possibility for the mass production of high-performance electrode materials for high-capacity Li-S battery. | ZHANG Chen LIU Donghai GENG Chuannan HUA Wuxing TANG Quanjun LING Guowei YANG Quan-Hong | 2021 | Chemical Research in Chinese Universities2021，37，2： | 0 |
