| 1 | Honeycomb-patterned films of polystyrene/poly(ethylene glycol): Preparation, surface aggregation and protein adsorption显示文摘Highly ordered honeycomb-patterned polystyrene (PS)/poly(ethylene glycol) (PEG) films were prepared by a water-assisted method using an improved setup, which facilitated the formation of films with higher regularity, better reproducibility, and larger area of honeycomb structures. Surface aggregation of hydrophilic PEG and adsorption of bovine serum albumin (BSA) on the honeycomb-patterned films were investigated. Field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM) were used to observe the surface morphologies of the films before and after being rinsed with water. As confirmed by the FESEM images and the AFM phase images, PEG was enriched in the pores and could be gradually removed by water. The adsorption of fluorescence-labeled BSA on the films was studied in visual form using laser scanning confocal microscopy. Results clearly demonstrated that the protein-resistant PEG was selectively enriched in the pores. This water-assisted method may be a latent tool to prepare honeycomb-patterned biofunctional surfaces. | WAN LingShu KE BeiBei LI XiaoKai MENG XiangLin ZHANG LuYao XU ZhiKang | 2009 | Science China Chemistry2009，52，7： | 3 |
| 2 | Rapid and accurate detection of African swine fever virus by DNA endonuclease-targeted CRISPR trans reporter assay显示文摘The first case of African swine fever(ASF)outbreak in China was reported in a suburban pig farm in Shenyang in 2018.Since then,the rapid spread and extension of ASF has become the most serious threat fo r the swine industry.Therefore,rapid and accurate detection of African swine fever virus(ASFV)is essential to provide effective strategies to control the disease.In this study,we developed a rapid and accurate ASFV-detection method based on the DNA endonuclease-targeted CRISPR trans reporter(DETECTR)assay.By com bining recombinase polymerase am plification w ith CRISPR-Cas12a proteins,the DETECTR assay dem onstrated a m inim um detection lim it of eight copies with no cross reactivity with other swine viruses.Clinical blood samples were detected by DETECTR assay and showed 100%(30/30)agreement w ith real-tim e polymerase chain reaction assay.The rapid and accurate detection of ASFV may facilitate tim ely eradication measures and strict sanitary procedures to control and prevent the spread of ASF. | Zongjie Li Jianchao Wei Di Di Xin Wang Chenxi Li Beibei Li Yafeng Qiu Ke Liu Feng Gu Minglong Tong Shuiming Wang Xiaodong Wu Zhiyong Ma | 2020 | Acta Biochimica et Biophysica Sinica2020，52，12： | 2 |
| 3 | Tumor suppressor p53 functions as an essential antiviral molecule against Japanese encephalitis virus显示文摘Japanese encephalitis virus(JEV)is a mosquito-borne virus of the family Flaviviridae.It is the causative agent of Japanese encephalitis with approximately 50,000 infection cases and 10,000 fatal cases annually in Asia(Erlanger et al.,2009).Although liveattenuated JEV vaccine has been developed and used for human and pig vaccination,JE occurs epidemically or sporadically | Xufang Deng Jianchao Wei Zixue Shi Wenjun Yan Zhuanchang Wu Donghua Shao Beibei Li Ke Liu Xiaodu Wang Yafeng Qiu Zhiyong Ma | 2016 | Journal of Genetics and Genomics2016，43，12： | 1 |

| 6 | High-Performance D-A Copolymer Donor Based on Difluoroquinoxaline A-Unit with Alkyl-Chlorothiophene Substituents for Polymer Solar Cells显示文摘Side chain engineering with fluorine substitution is widely used to enhance photovoltaic performance of polymer donors in the research field of polymer solar cells(PSCs).However,fluorine substitution has disadvantages of complicated synthesis and high cost.Herein,we synthesized a novel D-A copolymer donor PBQ9 based on difluoroquinoxaline A-unit with chlorine substitution on its alkyl-thiophene side chains instead of fluorine substitution in the polymer donor PBQ6,which greatly shortens the synthetic route and reduces the cost.Interestingly,the optimized binary PSC with PBQ9 as polymer donor and m-TEH as acceptor demonstrated a high power conversion efficiency(PCE)of 18.81%(certified PCE of 18.33%by National Institute of Metrology,China)with a high fill factor of 80.59%,and the photovoltaic performance of the PSCs is insensitive to the different batches of the polymer donor.The results indicate that PBQ9 is a high-performance polymer donor and that chlorine substitution is an effective strategy to improve photovoltaic performance and reduce the cost of polymer donors. | Can Zhu Ke Hu Lei Meng Xiaolei Kong Wenbin Lai Shucheng Qin Beibei Qiu Jinyuan Zhang Zhanjun Zhang Yilei Wu Xiaojun Li Yongfang Li | 2023 | CCS Chemistry2023，5，10： | 0 |
| 7 | Photo-processing of perovskites:current research status and challenges显示文摘The past two decades have seen a drastic progress in the development of semiconducting metal-halide perovskites(MHPs)from both the fundamentally scientific and technological points of view.The excellent optoelectronic properties and device performance make perovskites very attractive to the researchers in materials,physics,chemistry and so on.To fully explore the potential of perovskites in the applications,various techniques have been demonstrated to synthesize perovskites,modify their structures,and create patterns and devices.Among them,photo-processing has been revealed to be a facile and general technique to achieve these aims.In this review,we discuss the mechanisms of photo-processing of perovskites and summarize the recent progress in the photo-processing of perovskites for synthesis,patterning,ion exchange,phase transition,assembly,and ion migration and redistribution.The applications of photo-processed perovskites in photovoltaic devices,lasers,photodetectors,light-emitting diodes(LEDs),and optical data storage and encryption are also discussed.Finally,we provide an outlook on photo-processing of perovskites and propose the promising directions for future researches.This review is of significance to the researches and applications of perovskites and also to uncover new views on the light-matter interactions. | Dezhi Tan Ke Sun Zengling Li Beibei Xu Jianrong Qiu | 2022 | Opto-Electronic Science2022，1，11： | 0 |
| 8 | Atomically Dispersed Manganese Lewis Acid Sites Catalyze Electrohydrogenation of Nitrogen to Ammonia显示文摘Ambient electrochemical nitrogen fixation is a promising and environmentally benign route for producing sustainable ammonia,but has been limited by the poor performance of existing catalysts that promote the balanced chemisorption of N2 and subsequent electrochemical activation and hydrogenation.Herein,we describe the highly selective and efficient electrohydrogenation of nitrogen to ammonia using a hollow nanorod-based hierarchically graphitic carbon electrocatalyst with abundant atomically dispersed Mn sites.We discovered that the electron interactions strengthen the interfacial binding between nitrogen and active Mn Lewis acidic hotspots.The Lewis acid-base interactions promote the chemisorption and lock up nitrogen on the active sites and suppress proton adsorption.The proton-coupled electron transfer cleavage of the nitrogen triple bond through an associative mechanism was confirmed under lower overpotential,which delivered high ammonia yield of 67.5μg h−1 mgcat.−1 and Faradaic efficiency of 13.7% at−0.25 V versus the reversible hydrogen electrode,along with∼100% selectivity and significantly enhanced electrochemical stability(about 88.8% current retention over 50 h potentiostatic test)under mild conditions.Our strategy is versatile to tailor the nitrogen fixation performance of single-atom catalysts with atomic accuracy. | Zhoutai Shang Bin Song Hongbao Li Hong Zhang Fan Feng Jacob Kaelin Wenli Zhang Beibei Xie Yingwen Cheng Ke Lu Qianwang Chen | 2022 | CCS Chemistry2022，4，6： | 0 |
