| 1 | Hybrids perfluorosulfonic acid ionomer and silicon oxide membrane for application in ion-exchange polymer-metal composite actuators显示文摘This paper reports a new technique to fabricate an ion-exchange polymer-metal composite (IPMC) actuator. This technique is based on a hybrid organic-inorganic composite membrane. In the fabrication course, silica oxide particles, prepared from hydrolysis of tetraethyl orthosilicate in situ with sol-gel reaction, co-crystallize with perfluorosulfonate acid (PFSA) ionomer. Attenuated total reflectance fourier transform infrared spectroscopy (ATR-FTIR) analyses demonstrate that a highly water-saving hybrid membrane is formed. Measurements of mechanical properties reveal that elastic modulus and hardness of the hybrid membrane are about 2 times compared to a commercial PFSA membrane. Scanning electron microscopy (SEM) results show that the hybrid membrane has a high porosity. Inside the membrane pores, there exists a great quantity of micro scale channels in the range of 100―300 nm. After fabrication of IPMC actuator, an electric current sensor, a force sensor, and a high speed camera are assembled and used to evaluate IPMC performance. It is shown that, compared to an IPMC actuator made from a commercial membrane, the electromechanical performance of the new actuator increases 6―8 times; when it is actuated in air, its stable non-water working time is prolonged for 6―7 times. | GUO DongJie DING HaiTao WEI HaiJu HE QingSong YU Min DAI ZhenDong | 2009 | Science China(Technological Sciences)2009，52，10： | 10 |

| 6 | Amorphous TiO_2-supported Keggin-type ionic liquid catalyst catalytic oxidation of dibenzothiophene in diesel显示文摘Supported ionic liquid(IL) catalysts [C_nmim]_3PMo_(12)O_(40)/Am TiO_2(amorphous TiO_2) were synthesized through a one-step method for extraction coupled catalytic oxidative desulfurization(ECODS) system. Characterizations such as FTIR, DRS,wide-angle XRD, N_2 adsorption–desorption and XPS were applied to analyze the morphology and Keggin structure of the catalysts. In ECODS with hydrogen peroxide as the oxidant, it was found that ILs with longer alkyl chains in the cationic moiety had a better effect on the removal of dibenzothiophene. The desulfurization could reach 100% under optimal conditions, and GC–MS analysis was employed to detect the oxidized product after the reaction. Factors affecting the desulfurization efficiencies were discussed, and a possible mechanism was proposed. In addition, cyclic experiments were also conducted to investigate the recyclability of the supported catalyst. The catalytic activity of [C_(16)mim]_3 PMo_(12)O_(40)/Am TiO_2 only dropped from 100% to 92.9% after ten cycles, demonstrating the good recycling performance of the catalyst and its potential industrial application. | Zhendong Yu Donghui Wang Suhang Xun Minqiang He Ruliang Ma Wei Jiang Hongping Li Wenshuai Zhu Huaming Li | 2018 | Petroleum Science2018，15，4： | 3 |
| 7 | Construction of Non-infectious SARS-CoV-2 Replicons and Their Application in Drug Evaluation显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has caused a devastating pandemic worldwide.Vaccines and antiviral drugs are the most promising candidates for combating this global epidemic,and scientists all over the world have made great efforts to this end.However,manipulation of the SARS-CoV-2 should be performed in the biosafety level3 laboratory.This makes experiments complicated and time-consuming.Therefore,a safer system for working with this virus is urgently needed.Here,we report the construction of plasmid-based,non-infectious SARS-CoV-2 replicons with turbo-green fluorescent protein and/or firefly luciferase reporters by reverse genetics using transformation-associated recombination cloning in Saccharomyces cerevisiae.Replication of these replicons was achieved simply by direct transfection of cells with the replicon plasmids as evident by the expression of reporter genes.Using SARS-CoV-2 replicons,the inhibitory effects of E64-D and remdesivir on SARS-CoV-2 replication were confirmed,and the halfmaximal effective concentration(EC50)value of remdesivir and E64-D was estimated by different quantification methods respectively,indicating that these SARS-CoV-2 replicons are useful tools for antiviral drug evaluation. | Bei Wang Chongyang Zhang Xiaobo Lei Lili Ren He Huang Jianwei Wang Zhendong Zhao | 2021 | Virologica Sinica2021，36，5： | 3 |
| 8 | Force optimization of ionic polymer metal composite actuators by an orthogonal array method显示文摘Ionic polymer metal composites (IPMCs), a new kind of electro-active polymer, can be used for micro robotic actuators, artificial muscles and dynamic sensors. However, IPMC actuators have the major drawbacks of a low generative blocking force and dependence on a humid environment, which limit their further application. Multiple process parameters for the fabrication of IPMCs were optimized to produce a maximum blocking force; the parameters included reducing agent concentration, platinum salt concentration in the initial compositing process, and tetraethyl orthosilicate (TEOS) content. An orthogonal array method was designed and a series of fabrication experiments were carried out to identify the optimum process parameters. The results show that the platinum salt concentration in the initial compositing process plays the most significant role in improving the blocking force of IPMCs, the TEOS content plays an important role, and the reducing agent concentration has no apparent effect on the blocking force. In the optimized conditions, the IPMC actuator exhibited maximum blocking force of 50 mN, and the corresponding displacement was 14 mm. Compared with normal conditions, the blocking force improved 2.4-fold without sacrificing the displacement, and the effective air-operating life was prolonged 5.8-fold for the blocking force and 5-fold for the displacement. This study lays a solid foundation for further applications of IPMCs. | YU Min HE QingSong DING Yan GUO DongJie LI JiaBo DAI ZhenDong | 2011 | Chinese Science Bulletin2011，56，19： | 3 |

| 11 | Optimized Bio-inspired Micro-pillar Dry Adhesive and Its Application for an Unmanned Aerial Vehicle Adhering on and Detaching from a Ceiling显示文摘Various bio-inspired dry adhesive materials have been investigated.In this work,lithography and silicon deep etching method were used to fabricate bio-inspired micro-pillar dry adhesive materials of which the parameters,such as side length,Height to Side length Aspect Ratio(HSAR),and inter-pillar Distance to Side length Aspect Ratio(DSAR)were comprehensively studied to obtain a dry adhesive with high adhesion.An orthogonal array method was designed and a series of fabrication experiments were conducted to identify optimum parameters,which resulted in a high normal adhesion of 2.98 N·cm^-2 and a shear adhesion of 9.59 N·cm^-2.An adhesion and desorption device was further designed on basis of the optimum dry adhesive,which enables an Unmanned Aerial Vehicle(UAV)to successfully adhere on and detach from a ceiling.This would allow an UAV to stay aloft for prolonged time,which could be invaluable to many applications,such as energy conservation and aerial detection. | Qingsong He Xianrui Xu Zhiwei Yu Kai Huo Zhaoyang Wang Nuo Chen Xuean Sun Gui Yin Peile Du Yang Li Zhendong Dai | 2020 | Journal of Bionic Engineering2020，17，1： | 2 |

| 14 | Post-combustion slipstream CO_(2)-capture test facility at Jiangyou Power Plant,Sichuan,China:facility design and validation using 30% wt monoethanolamine(MEA)testing显示文摘Given the dominant share of coal in China’s energy-generation mix and the fact that>50% of the power plants in the country are currently<15 years old,efforts to significantly reduce China’s CO_(2) footprint will require the deployment of CO_(2) capture across at least part of its fleet of coal-fired power plants.CO_(2)-capture technology is reaching commercial maturity,but it is still necessary to adapt the technology to regional conditions,such as power-plant design and flexible operation in the China context.Slipstream facilities provide valuable field data to support the commercialization of CO_(2) capture.We have built a slipstream facility at Jiangyou power plant in Sichuan that will allow us to explore China-relevant issues,especially flexible operation,over the next few years.We plan to share our results with the broader CO_(2)-capture and CO_(2)-storage(CCS)community to accelerate the deployment of CCS in China.This paper describes the design of the slipstream facility and presents results from our steady-state qualification tests using a well-studied benchmark solvent:30% wt monoethanolamine(MEA).The results from our MEA tests compare favorably to results reported from other slipstream-test facilities around the world,allowing us to commission our system and establish a reference baseline for future studies. | Baodeng Wang Qian Cui Guoping Zhang Yinhua Long Yongwei Sun Xinglei Zhao Zhendong He Anthony Y.Ku | 2020 | Clean Energy2020，4，2： | 1 |

| 16 | The Ubiquitin E3 Ligase PUB17 Positively Regulates Immunity by Targeting a Negative Regulator, KH17, for Degradation显示文摘Ubiquitination is a post-translational modification that regulates many processes in plants.Several ubiquitin E3 ligases act as either positive or negative regulators of immunity by promoting the degradation of different substrates.StPUB17 is an E3 ligase that has previously been shown to positively regulate immunity to bacteria,fungi and oomycetes,including the late blight pathogen Phytophthora infestans.Silencing of StPUB17 promotes pathogen colonization and attenuates Cf4/avr4 cell death.Using yeast-2-hybrid and co-immunoprecipitation we identified the putative K-homology(KH)RNA-binding protein(RBP),StKH17,as a candidate substrate for degradation by StPUB17.StKH17 acts as a negative regulator of immunity that promotes P.infestans infection and suppresses specific immune pathways.A KH RBP domain mutant of StKH17(StKH17GDDG)is no longer able to negatively regulate immunity,indicating that RNA binding is likely required for StKH17 function.As StPUB17 is a known target of the ubiquitin E3 ligase,StPOB1,we reveal an additional step in an E3 ligase regulatory cascade that controls plant defense. | Hazel McLellan Kai Chen Qin He Xintong Wu Petra C.Boevink Zhendong Tian Paul R.J.Birch | 2020 | Plant Communications2020，1，4： | 1 |
| 17 | A Novel DT40 Antibody Library for the Generation of Monoclonal Antibodies显示文摘Early etiological diagnosis is very important for the control of sudden viral infections,and requires antibodies with both high sensitivity and high specificity.Traditional antibody preparation methods have limitations,such as a long and arduous cycle,complicated operation,and high expenses.A chicken lymphoma cell line,DT40,is known to produce IgM-type antibodies and undergo gene conversion and somatic mutation in the variable region of the immunoglobulin gene during culture.Here,the DT40 cell line was developed to produce antibody libraries and prepare antibody rapidly in vitro.Since hypermutation in DT40 cells was regulated by the activation-induced cytidine deaminase(AID)gene,AID expression needs to be controlled to either fix the Ig sequence by stopping mutation or improve affinity by resuming mutation after the antibodies have been selected.In this study,we generated a novel AID-inducible DT40 cell line(DT40-H7),in which the endogenous AID gene was knocked out using the CRISPR/Cas9 genome editing system,and an inducible AID gene,based on the Tet-Off expression system,was stably transfected.AID expression was controlled in DT40-H7 cells in a simple and efficient manner;gene conversion and point mutations were observed only when AID was expressed.Using the antibody library generated from this cell line,we successfully obtained monoclonal antibodies against the NS1 protein of Zika virus.The DT40-H7 cell line represents a useful tool for the selection and evolution of antibodies and may also be a powerful tool for the rapid selection and generation of diagnostic antibodies for emerging infectious diseases. | Bei Wang Fei Wang He Huang Zhendong Zhao | 2019 | Virologica Sinica2019，34，6： | 1 |

| 19 | Post-combustion slipstream CO_(2)-capture test facility at Jiangyou Power Plant, Sichuan, China: performance of a membrane separation module under dynamic power-plant operations显示文摘Membrane-based separation technologies have the potential to lower the cost of post-combustion CO_(2) capture from power-plant flue gases through reduced energy and capital costs relative to conventional solvent approaches.Studies have shown promise under controlled conditions,but there is a need for data on performance and reliability under field conditions.Coal-fired power plants in China operate in a dynamic manner,with increases and decreases in output causing changes in flue-gas composition.In this paper,we describe the first field test of a membrane-based post-combustion CO_(2)-capture system connected to a dynamically operating power plant in China.We report the performance of a Membrane Technology Research,Inc.(MTR)Polaris^(TM) membrane-based capture system over a range of plant operating loads ranging from 54%to 84%and conducted an operational stability test over a 168-h period during which the power plant was operating at an average load of 55%,but ramped as high as 79%and as low as 55%.Our results confirm the ability of a membrane capture system to operate effectively over a wide range of host-plant operating conditions,but also identity several issues related to plant integration,system control and resilience in the face of host-plant upsets that require attention as membrane separation systems move towards commercial use. | Qian Cui Baodeng Wang Xinglei Zhao Guoping Zhang Zhendong He Yinhua Long Yongwei Sun Anthony Y.Ku | 2021 | Clean Energy2021，5，4： | 1 |
