| 1 | Highly conductive dodecaborate/MXene composites for high performance supercapacitors显示文摘With the increasingly prominent energy and environmental issues,the supercapacitors,as a highly efficient and clean energy conversion and storage devices,meet the requirements well.However,it is still a challenge to enhance the capacitance and energy density of supercapacitors.A novel and highly conductive dodecaborate/MXene composites have been designed for high performance supercapacitors.The surface charge property of MXene was modified by a simple ultrasonic treatment with ammonium ion,and the dodecaborate ion can be inserted into the inner surface of MXene by electrostatic adsorption.Due to the unique icosahedral cage conjugate structure formed by the B-B bond and the highly delocalized three-dimensionalπbond structure of the electrons,the negative charge is delocalied on the whole dodecaborate ion,which reduces the ability to bind to cations.Therefore,the cations can move easily,and the dodecaborate can act as a“lubricant”for ion diffusion between the MXene layers,which significantly improves the ion transfer rate of supercapacitors.The dodecaborate/MXene composites can achieve an extremely high specific capacitance of 366 F.g^-1 at a scan rate of 2 mV.s^-1,which is more than eight times higher than that of MXene(43 F1-)at the same scan rate.Our finding provides a novel route on the fabrication of the high performance supercapacitors. | Zhenxing Li Chang Ma Yangyang Wen Zhiting Wei Xiaofei Xing Junmei Chu Chengcheng Yu Kaili Wang Zhao-Kui Wang | 2020 | Nano Research2020，13，1： | 7 |
| 2 | Chromosome-level genome of Himalayan yew provides insights into the origin and evolution of the paclitaxel biosynthetic pathway显示文摘Taxus,commonly known as yew,is a well-known gymnosperm with great ornamental and medicinal value.In this study,by assembling a chromosome-level genome of the Himalayan yew(Taxus wallichiana)with 10.9 Gb in 12 chromosomes,we revealed that tandem duplication acts as the driving force of gene family evolution in the yew genome,resulting in the main genes for paclitaxel biosynthesis,i.e.those encoding the taxadiene synthase,P450s,and transferases,being clustered on the same chromosome.The tandem duplication may also provide genetic resources for the nature to sculpt the core structure of taxoids at different positions and subsequently establish the complex pathway of paclitaxel by neofunctionalization.Furthermore,we confirmed that there are two genes in the cluster encoding isoenzymes of a known enzyme in the paclitaxel biosynthetic pathway.The reference genome of the Himalayan yew will serve as a platform for decoding the complete biosynthetic pathway of paclitaxel and understanding the chemodi-versity of taxoids in gymnosperms. | Jian Cheng Xiao Wang Xiaonan Liu Xiaoxi Zhu Zihe Li Huanyu Chu Qian Wang QianQian Lou Bijun Cai Yiqun Yang Xiaoyun Lu Kai Peng Dingyu Liu Yuwan Liu Lina Lu Huan Liu Ting Yang Qijin Ge Chengcheng Shi Guichun Liu Zhiwei Dong Xun Xu Wen Wang Huifeng Jiang Yanhe Ma | 2021 | Molecular Plant2021，14，7： | 6 |
| 3 | Numerical study on dynamic mechanism of brain volume and shear deformation under blast loading显示文摘Blast-induced traumatic brain injury(b-TBI)is a kind of significant injury to soldiers in the current military conflicts.However,the mechanism of b-TBI has not been well understood,and even there are some contradictory conclusions.It is crucial to reveal the dynamic mechanism of brain volume and shear deformations under blast loading for better understanding of b-TBI.In this paper,the numerical simulation method is adopted to carry out comprehensive and in-depth researches on this issue for the first time.Based on the coupled Eulerian-Lagrangian method,the fluid-structure coupling model of the blast wave and human head is developed to simulate two situations,namely the head subjected to the frontal and lateral impacts.The simulation results are analyzed to obtain the underlying dynamic mechanisms of brain deformation.The brain volume deformation is dominated by the local bending vibration of the skull,and the corresponding frequency for the forehead skull under the frontal impact and the lateral skull faced to the lateral impact is as high as 8 kHz and 5 kHz,respectively.This leads to the high-frequency fluctuation of brain pressure and the large pressure gradient along the skull,totally different from the dynamic response of brain under head collisions.While the brain shear deformation mainly depends on the relative tangential displacement between the skull and brain and the anatomical structure of inner skull,being not related to the brain pressure and its gradient.By further comparing the medical statistics,it is inferred that diffuse axonal injury and brain contusion,the two most common types of b-TBI,are mainly attributed to brain shear deformations.And the von Mises stress can be adopted as the indicator for these two brain injuries.This study can provide theoretical guidance for the diagnosis of b-TBI and the development of protective equipment. | Zhijie Li Zhibo Du Xiaochuan You Zhanli Liu Jian Cheng Chengcheng Luo Dongyang Chu Shaowu Ning Yue Kang Ce Yang Zhuo Zhuang | 2019 | Acta Mechanica Sinica2019，35，5： | 3 |
| 4 | A Three-Dimensional Silicon-Diacetylene Porous Organic Radical Polymer显示文摘Radical-containing porous organic polymers(POPs)have drawn great interest in various applications.However,the synthesis of radical POPs remains challenging due to the unstable nature of organic radicals.Here,a persistent and stable three-dimensional silicon-diacetylene porous organic radical polymer was synthesized via a classic Eglinton homocoupling reaction of tetraethynylsilane.The presence of carbon radicals in this material was confirmed by electron paramagnetic resonance,and its paramagnetic behavior was analyzed by a superconducting quantum interference device.This unique material has a low-lying lowest unoccupied molecular orbital(LUMO)energy level(−5.47 eV)and a small energy gap(ca.1.46 eV),which shows long-term cycling stability and excellent rate capability as an anode material for lithium-ion batteries,demonstrating potential application in energy fields. | Chengcheng Dong Juan Chu Linzhu Cao Fengchao Cui Shuang Liang Xintong Zhang Xin Tao Heng-guo Wang Guangshan Zhu | 2023 | CCS Chemistry2023，5，3： | 0 |
| 5 | Integrated Photothermal Nanoreactors for Effi cient Hydrogenation of CO_(2)显示文摘To alleviate the energy crisis and global warming,photothermal catalysis is an attractive way to effi ciently convert CO_(2)and renewable H_(2) into value-added fuels and chemicals.However,the catalytic performance is usually restricted by the trade-off between the dispersity and light absorption property of metal catalysts.Here we demonstrate a simple SiO 2-protected metal-organic framework pyrolysis strategy to fabricate a new type of integrated photothermal nanoreactor with a comparatively high metal loading,dispersity,and stability.The core-satellite structured Co@SiO_(2)exhibits strong sunlight-absorptive abil-ity and excellent catalytic activity in CO_(2)hydrogenation,which is ascribed to the functional separation of diff erent sizes of Co nanoparticles.Large-sized plasmonic Co nanoparticles are mainly responsible for the light absorption and conversion to heat(nanoheaters),whereas small-sized Co nanoparticles with high intrinsic activities are responsible for the catalysis(nanoreactors).This study provides a new concept for designing effi cient photothermal catalytic materials. | Jiahui Shen Rui Tang Zhiyi Wu Xiao Wang Mingyu Chu Mujin Cai Chengcheng Zhang Liang Zhang Kui Yin Le He Chaoran Li | 2022 | Transactions of Tianjin University2022，28，4： | 0 |

| 7 | Modification strategies on 2D Ni-Fe MOF-based catalysts in peroxydisulfate activation for efficient organic pollutant removal显示文摘This study reports several modification strategies to optimize and enhance the performance of twodimensional(2D) metal organic frameworks(MOFs)-derived catalysts in peroxydisulfate(PDS) activation.The raw 2D Ni-MOF and 2D Ni-Fe-MOF without modification show poor catalytic activities for PDS activation and high metal ion leaching. The carbonization of 2D MOF can increase the activity of the catalyst but cannot solve the metal leaching problem. The further acid treatment of carbonization products can further improve the catalytic activity and decrease the metal ion leaching. The in-situ growth of2D MOF on graphene oxide(GO) support with subsequent carbonization and acid treatment offers the best performance in PDS activation for organic pollutant removal with low metal ion leaching. Compared with other PDS systems, the Ni-Fe-C-acid/GO system displays much lower catalyst and PDS dosages for p-chloroaniline degradation. This study presents new insights in the modification strategies of 2D MOFbased catalysts in PDS activation. | Minjun Liu Ying Liu Xinru Liu Chengcheng Chu Ducheng Yao Shun Mao | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
