| 1 | Nanozymes: created by learning from nature显示文摘Nanozymes,a type of nanomaterials with enzyme-like activity,have shown great potential to replace natural enzymes in many fields such as biochemical detection,environmental management and disease treatment.However,the catalytic efficiency and substrate specificity of nanozymes still need improvement.To further optimize the enzymatic properties of nanozymes,recent studies have introduced the structural characteristics of natural enzymes into the rational design of nanozymes,either by employing small molecules to mimic the cofactors of natural enzymes to boost nanozymes’catalytic potential,or by simulating the active center of natural enzymes to construct the nanostructure of nanozymes.This review introduces the commonly used bio-inspired strategies to create nanozymes,aiming at clarifying the current progress and bottlenecks.Advances and challenges focusing on the research of bio-inspired nanozymes are outlined to provide ideas for the de novo design of ideal nanozymes. | Ruofei Zhang Kelong Fan Xiyun Yan | 2020 | Science China(Life Sciences)2020，63，8： | 13 |
| 2 | Nanozymes Inspired by Natural Enzymes显示文摘CONSPECTUS:Nanozymes,nanomaterials with enzyme-like activities with high structural stability,adjustable catalytic activity,functional diversity,recyclability,and feasibility in large-scale preparation,have become a hot spot in the field of artificial enzymes in recent years and are expected to become potential surrogates and competitors for natural enzymes in practical applications.With the development of in-depth research and a wide range of application requirements,creating nanozymes with catalytic performance comparable to or even surpassing that of natural enzymes has been the key research topic in this field.Most of the nanozymes reported in the past were obtained based on random synthesis and screening,for which the catalytic efficiency is far inferior to that of natural enzymes.Natural enzymes that have evolved over hundreds of millions of years have developed a lot of high-efficiency catalysis know-how hidden in their structural features.To create highly active nanozymes,we assumed that there is a general structure−activity relationship between nanozymes and natural enzymes and proposed the nanozyme optimization strategy by grafting the catalytic principles of natural enzymes into the rational design of nanozymes.On the basis of this bioinspired strategy,a series of nanozymes that exhibit similar catalytic activities that are closer to or even beyond those of natural enzymes have been successfully synthesized.By now,rationally designed high-activity bioinspired nanozymes have become a hot topic in the current research on nanozymes.In this Account,we focus on recent representative research progress in the systemic design and construction of bioinspired nanozymes and are devoted to introducing strategic concepts in the bioinspired optimization of nanozymes.We show that the de novo design of nanozymes by simulating the amino acid microenvironment and using metal-free architecture and the coordination structure of metal active sites in natural enzymes is an effective strategy for significantly improving the catalytic performance of nanozymes.A future perspective of the challenges and countermeasures of bioinspired nanozymes is proposed on the basis of these achievements.We hope that the biologically inspired perception will arouse widespread interest in fundamental research and practical applications as well as provide inspiration for the rational design of nanozymes. | Ruofei Zhang Xiyun Yan Kelong Fan | 2021 | Accounts of Materials Research2021，2，7： | 8 |
| 3 | Removal of nitric oxide from simulated flue gas via denitrification in a hollow-fiber membrane bioreactor显示文摘A hollow-fiber membrane bioreactor(HMBR) was studied for its ability to treat nitric oxide(NO) from simulated flue gas. The HMBR was operated for 9 months and showed a maximum elimination capacity of 702 mg NO/(m2·day) with a removal efciency of 86%(gas residence time of 30 sec, inlet NO concentration of 2680 mg/m3, pH 8). Varying operation parameters were tested to determine the stability and response of the HMBR. Both the inlet NO concentration and gas residence time influenced the removal of NO in the HMBR. NO elimination capacity increased with an increase in inlet NO concentration or a shortening of gas residence time. Higher removal efciency of NO was obtained at a longer gas residence time or a lower inlet NO concentration. Microbial communities of the HMBR were sensitive to the variation in pH value and alkalescence corresponding to an optimum pH value of 8. In addition, NO elimination capacity and removal efciency were inversely proportional to the inlet oxygen concentration. Sulfur dioxide had no great influence on elimination capacity and removal efciency of NO. Product analysis was performed to study N2O and N2 production and confirmed that the majority of the microorganisms were denitrifying bacteria in the HMBR. Compared to other bioreactors treating NO, this study showed that the denitrifying HMBR was a good option for the removal of NO. | Xinyu Zhang Ruofei Jin Guangfei Liu Xiyang Dong Jiti Zhou Aijie Wang | 2013 | Journal of Environmental Sciences2013，25，11： | 5 |
| 4 | External-force-driven solution epitaxy of large-area 2D organic single crystals for high-performance field-effect transistors显示文摘Growth of two-dimensional(2D)organic single crystals(2DOSCs)on water surface has attracted increasing attention,because it can serve as a molecularly flat and defect-free substrate.However,large-area growth of 2DOSCs with controllable crystal orientation on water surface remains a key challenge.Herein,we develop a simple method,i.e.external-force-driven solution epitaxy(EFDSE),for the large-area growth of 2DOSCs at air/water interface.Using 2,7-didecylbenzothienobenzothiophene(C1o-BTBT)as an example,high-quality 2D C10-BTBT crystals on centimeter scale are generated by directionally controlling the spreading of organic solution on water surface with external force.Benefiting from the controllable crystal orientation with optimal charge transport,the corresponding 2DOSC-based organic field-effect transistors(OFETs)exhibit a high carrier mobility of 13.5 cm^2·V^-1·s^-1(effective mobility=5.4 cm^2·V^-1·s^-1 according to a reliability factor of 40%),which represents the best result achieved for water-surface-assembled 2DOSC based OFETs.Furthermore,by transterring the C1o-BTBT 2DOSCs to flexible substrates,devices with excellent bending stability are achieved.It is anticipated that our method will provide new insight into the controllable growth of large-area 2DOSCs for high-performance organic devices. | Jinwen Wang Wei Deng Wei Wang Ruofei Jia Xiuzhen Xu Yanling Xiao Xiujuan Zhang Jiansheng Jie Xiaohong Zhang | 2019 | Nano Research2019，12，11： | 3 |
| 5 | Refined spatial temporal epigenomic profiling reveals intrinsic connection between PRDM9-mediated H3K4me3 and the fate of double-stranded breaks显示文摘Meiotic recombination is initiated by the formation of double-strand breaks(DSBs),which are repaired as either crossovers(COs)or noncrossovers(NCOs).In most mammals,PRDM9-mediated H3K4me3 controls the nonrandom distribution of DSBs;however,both the timing and mechanism of DSB fate control remain largely undetermined.Here,we generated comprehensive epigenomic profiles of synchronized mouse spermatogenic cells during meiotic prophase I,revealing spatiotemporal and functional relationships between epigenetic factors and meiotic recombination.We find that PRDM9-mediated H3K4me3 at DSB hotspots,coinciding with H3K27ac and H3K36me3,is intimately connected with the fate of the DSB.Our data suggest that the fate decision is likely made at the time of DSB formation:earlier formed DSBs occupy more open chromatins and are much more competent to proceed to a CO fate.Our work highlights an intrinsic connection between PRDM9-mediated H3K4me3 and the fate decision of DSBs,and provides new insight into the control of CO homeostasis. | Yao Chen Ruitu Lyu Bowen Rong Yuxuan Zheng Zhen Lin Ruofei Dai Xi Zhang Nannan Xie Siqing Wang Fuchou Tang Fei Lan Ming-Han Tong | 2020 | Cell Research2020，30，3： | 3 |

| 8 | Facile controlled synthesis of hierarchically structured mesoporous Li_(4)Ti_(5)O_(12)/C/rGO composites as high-performance anode of lithium-ion batteries显示文摘t In this paper,a facile strategy is proposed to controllably synthesize mesoporous Li_(4)Ti_(5)O_(12)/C nanocomposite embedded in graphene matrix as lithium-ion battery anode via the co-assembly of Li_(4)Ti_(5)O_(12)(LTO)precursor,GO,and phenolic resin.The obtained composites,which consists of a LTO core,a phenolic-resin-based carbon shell,and a porous frame constructed by rGO,can be denoted as LTO/C/rGO and presents a hierarchical structure.Owing to the advantages of the hierarchical structure,including a high surface area and a high electric conductivity,the mesoporous LTO/C/rGO composite exhibits a greatly improved rate capability as the anode material in contrast to the conventional LTO electrode. | Cehuang FU Shuiyun SHEN Ruofei WU Xiaohui YAN Guofeng XIA Junliang ZHANG | 2022 | Frontiers in Energy2022，16，4： | 0 |
| 9 | Textured Asymmetric Membrane Electrode Assemblies of Piezoelectric Phosphorene and Ti_(3)C_(2)T_(x)MXene Heterostructures for Enhanced Electrochemical Stability and Kinetics in LIBs显示文摘Black phosphorus with a superior theoretical capacity(2596 mAh g^(-1))and high conductivity is regarded as one of the powerful candidates for lithium-ion battery(LIB)anode materials,whereas the severe volume expansion and sluggish kinetics still impede its applications in LIBs.By contrast,the exfoliated two-dimensional phosphorene owns negligible volume variation,and its intrinsic piezoelectricity is considered to be beneficial to the Li-ion transfer kinetics,while its positive influence has not been discussed yet.Herein,a phosphorene/MXene heterostructure-textured nanopiezocomposite is proposed with even phosphorene distribution and enhanced piezo-electrochemical coupling as an applicable free-standing asymmetric membrane electrode beyond the skin effect for enhanced Li-ion storage.The experimental and simulation analysis reveals that the embedded phosphorene nanosheets not only provide abundant active sites for Li-ions,but also endow the nanocomposite with favorable piezoelectricity,thus promoting the Li-ion transfer kinetics by generating the piezoelectric field serving as an extra accelerator.By waltzing with the MXene framework,the optimized electrode exhibits enhanced kinetics and stability,achieving stable cycling performances for 1,000 cycles at 2 A g^(-1),and delivering a high reversible capacity of 524 m Ah g^(-1)at-20℃,indicating the positive influence of the structural merits of self-assembled nanopiezocomposites on promoting stability and kinetics. | Yihui Li Juan Xie Ruofei Wang Shugang Min Zewen Xu Yangjian Ding Pengcheng Su Xingmin Zhang Liyu Wei Jing‑Feng Li Zhaoqiang Chu Jingyu Sun Cheng Huang | 2024 | Nano-Micro Letters2024，16，4： | 0 |
| 10 | SETDB1-mediated CD147-K71 di-methylation promotes cell apoptosis in non-small cell lung cancer显示文摘Protein post-translational modifications(PTMs)are at the heart status of cellular signaling events and broadly involved in tumor progression.CD147 is a tumor biomarker with various PTMs,promoting tumor metastasis and metabolism reprogramming.Nevertheless,the relationship between the PTMs of CD147 and apoptosis has not been reported.In our study,we produced a specific anti-CD147-K71 di-methylation(CD147-K71me2)antibody by immunizing with a di-methylated peptide and observed that the level of CD147-K71me2 in non-small cell lung cancer(NSCLC)tissues were lower than that in NSCLC adjacent tissues.SETDB1 was identified as the methyltransferase catalyzing CD147 to generate CD147-K71me2.RNA-seq showed that FOSB was the most significant differentially expressed gene(DEG)between wild-type CD147(CD147-WT)and K71-mutant CD147(CD147-K71R)groups.Subsequently,we found that CD147-K71me2 promoted the expression of FOSB by enhancing the phosphorylation of p38,leading to tumor cell apoptosis.In vivo experiments showed that CD147-K71me2 significantly inhibited tumor progression by promoting cell apoptosis.Taken together,our findings indicate the inhibitory role of CD147-K71me2 in tumor progression from the perspective of post-translational modification,which is distinct from the pro-cancer function of CD147 itself,broadening our perspective on tumor-associated antigen CD147. | Ming-Yan Shi Yarong Wang Ying Shi Ruofei Tian Xiaohong Chen Hai Zhang Ke Wang Zhinan Chen Ruo Chen | 2024 | Genes & Diseases2024，11，2： | 0 |
