| 1 | Improving the activity and stability of Ni-based electrodes for solid oxide cells through surface engineering:Recent progress and future perspectives显示文摘Solid oxide cells(SOCs)have attracted great attention in the past decades because of their high conversion efficiency,low environmental pollution and diversified fuel options.Nickel-based catalysts are the most widely used fuel electrode materials for SOCs due to the low price and high activity.However,when hydrocarbon fuels are employed,nickel-based electrodes face serious carbon deposition challenges,leading to a rapid decline of cell performance.Great efforts have been devoted to understanding the occurrence of the coking reaction,and to improving the stability of the electrodes in hydrocarbon fuels.In this review,we summarize recent research progress of utilizing surface modification to improve the stability and activity of Ni-based electrodes for SOCs by preventing carbon coking.The review starts with a briefly introduction about the reaction mechanism of carbon deposition,followed by listing several surface modification technologies and their working principles.Then we introduce representative works using surface modification strategies to prevent carbon coking on Ni-based electrodes.Finally,we highlight future direction of improving electrode catalytic activity and anti-coking performance through surface engineering. | Junxian Pan Yongjian Ye Mengzhen Zhou Xiang Sun Yihan Ling Keiji Yashiro Yan Chen | 2021 | Materials Reports(Energy)2021，1，2： | 2 |
| 2 | Review of brain-computer interface based on steady-state visual evoked potential显示文摘The brain-computer interface(BCI)technology has received lots of attention in the field of scientific research because it can help disabled people improve their quality of life.Steady-state visual evoked potential(SSVEP)is the most researched BCI experimental paradigm,which offers the advantages of high signal-to-noise ratio and short training-time requirement by users.In a complete BCI system,the two most critical components are the experimental paradigm and decoding algorithm.However,a systematic combination of the SSVEP experimental paradigm and decoding algorithms is missing in existing studies.In the present study,the transient visual evoked potential,SSVEP,and various improved SSVEP paradigms are compared and analyzed,and the problems and development bottlenecks in the experimental paradigm are finally pointed out.Subsequently,the canonical correlation analysis and various improved decoding algorithms are introduced,and the opportunities and challenges of the SSVEP decoding algorithm are discussed. | Siyu Liu Deyu Zhang Ziyu Liu Mengzhen Liu Zhiyuan Ming Tiantian Liu Dingjie Suo Shintaro Funahashi Tianyi Yan | 2022 | Brain Science Advances2022，8，4： | 1 |

| 4 | Difference analysis of different parts of chicory based on HPLC fingerprint and multi-component content determination显示文摘Objective:To establish HPLC fingerprints of different parts of chicory stems,leaves,roots,flowers and seeds,and compare the similarities and differences of chemical components in different parts,so as to provide a scientific basis for the comprehensive utilization of chicory.Methods:To establish the HPLC fingerprint of chicory,the chromatographic column was chosen with Agilent ZORBAX Eclipse XDB-C_(18),the mobile phase was methanol(A)-0.2%formic acid(B),the flow rate was 1 mL/min,the column temperature was 30℃,and the detection wavelength was 254 nm.The Similarity Evaluation System of Chromatographic Fingerprint of Traditional Chinese Medicine(2012 Edition)was used to evaluate the similarity of different parts of decoction pieces,and the determination method of multi-component content was established based on fingerprint identification chromatographic peaks,and the determination results were analyzed.Results:The HPLC fingerprinting method of chicory was established.Sixteen chromatographic peaks were identified and 10 of them were identified as:caftaric acid(1),esculin(2),chlorogenic acid(3),esculetin(4),caffeic acid(5),cichoric acid(8),hyperoside(11),rutin(12),isochlorogenic acid C(14)and luteolin(16).The similarity of different parts was 0.084–0.701.At the same time,the total content of detected chemical components was ranked as flower>leaf>stem>root>seed.Roots did not contain caftaric acid,rutin,and luteolin,flowers did not contain luteolin,and seeds did not contain caftaric acid,cichoric acid,and luteolin.The content of cichoric acid in leaves was the most,and esculin in flowers was the most.Conclusion:The results of HPLC fingerprint and multi-component content determination revealed the similarity and difference of different parts of chicory from chemical composition,indicating that there were certain differences in different parts of chicory.The established HPLC fingerprinting method can provide a reference for quality control and evaluation of different parts of the chicory. | Mengzhen Yan Zhenling Zhang Yanze Liu | 2022 | Chinese Herbal Medicines2022，14，2： | 1 |
| 5 | Construction of interfacial dynamic bonds for high performance lignin/polymer biocomposites显示文摘Lignin is the largest natural aromatic biopolymer,but usually treated as industrial biomass waste.The development of lignin/polymer biocomposites can promote the high value utilization of lignin and the greening of polymers.However,the weak interfacial interaction between industrial lignin and polymer induces poor compatibility and serious agglomeration in polymer owing to the strong intermolecular force of lignin.As such,it is extremely difficult to prepare high performance lignin/polymer biocomposites.Recently,we proposed the strategy of in situ construction of interfacial dynamic bonds in lignin/polymer composites.By taking advantage of the abundant oxygen-containing polar groups of lignin,we inserted dynamic bonding connection such as hydrogen bonds and coordination bonds into the interphase between lignin and the polymer matrix to improve the interfacial interactions.Meanwhile,the natural amphiphilic structure characteristics of lignin were utilized to construct the hierarchical nanophase separation structure in lignin/polymer composites.The persistent problems of poor dispersity and interfacial compatibility of lignin in the polymer matrix were effectively solved.The lignin-modified polymer composites achieved simultaneously enhanced strength and toughness.This concise review systematically summarized the recent research progress of our group toward building high-performance lignin/polymer biocomposites through the design of interfacial dynamic bonds(hydrogen bonds,coordination bonds,and dynamic covalent bonds)between lignin and different polymer systems(polar plastics,rubber,polyurethane,hydrogels,and other polymers).Finally,the future development direction,main challenges,and potential solutions of lignin application in polymers were presented. | Jianbin Mo Haixu Wang Mengzhen Yan Jianhua Huang Rui Li Danting Sun Junjie Lei Xueqing Qiu Weifeng Liu | 2023 | Frontiers of Chemical Science and Engineering2023，17，10： | 0 |
| 6 | LncRNA KCNQ1OT1:Molecular mechanisms and pathogenic roles in human diseases显示文摘Long non-coding RNAs(lncRNAs)exhibit a length more than 200 nucleotides and they are characterized by non-coding RNAs(ncRNA)not encoded into proteins.Over the past few years,the role and development of lncRNAs have aroused the rising attention of researchers.To be specific,KCNQ1OT1,the KCNQ1 opposite strand/antisense transcript 1,is clearly classified as a regulatory ncRNA.KCNQ1OT1 is capable of interacting with miRNAs,RNAs and proteins,thereby affecting gene expression and various cell functions(e.g.,cell proliferation,migration,epithelialemesenchymal transition(EMT),apoptosis,viability,autophagy and inflammation).KCNQ1OT1 is dysregulated in a wide range of human diseases(e.g.,cardiovascular disease,cancer,diabetes,osteoarthritis,osteoporosis and cataract),and it is speculated to act as a therapeutic target for treating various human diseases.On the whole,this review aims to explore the biological functions,underlying mechanisms and pathogenic roles of KCNQ1OT1 in human diseases. | Fangqi Xia Yaqi Wang Mengzhen Xue Leiqi Zhu Dengke Jia Yue Shi Yan Gao Luoying Li Yuanyang Li Silong Chen Guangfu Xu Ding Yuan Chengfu Yuan | 2022 | Genes & Diseases2022，9，6： | 0 |
| 7 | Lrrc34 Is Highly Expressed in SSCs and Is Necessary for SSC Expansi on In Vitro显示文摘Objective To discover critical genes contributing to the sternness and maintenance of spermatogonial stem cells(SSCs)and provide new insights into the function of the leucine-rich repeat(LRR)family member Lrrc34(leudne-rich repeat-containing 34)in SSCs from mice.Methods Bioinformatic methods,including differentially expressed gene(DEG),gene ontology(GO)enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses,were used to uncover latent pluripotency-related genes.Reverse transcription-polymerase chain reaction(RT-PCR)and immunofluorescence analyses were utilized to verify the mRNA and protein expression levels,respectively.RNA interference of Lrrc34 using siRNA was performed to detect its transient impact on SSCs.Results Eight DEGs between ID4-EGFP+(G)and ID4-EGFP+/TSPAN8Hig11(TH),eight DEGs between G and ID4-EGFP+/TSPAN8Uw(TL)and eleven DEGs between TH and TL were discovered,and eleven proteinprotein interaction(PPI)modules were found to be significant in the PPI network of DEGs.One of the DEGs,Lrrc34,was selected as a potential pluripotency?related gene due to its differential expression among ID4-EGFP+spermatogonia subsets and its interaction with fibroblast growth factor 2 in the fifth module.Immunofluorescence experiments exhibited specific expression of Lrrc34 in a subpopulation of undifferentiated spermatogonia marked by LIN28A,and RT-PCR experiments confirmed the high expression of Lrrc34 in SSCs from P7 and adult mice.The transient knockdown of Lrrc34 in SSCs resulted in reduced colony sizes and significant changes in the transcriptome and apoptotic pathways.Conclusion Lrrc34 is highly expressed in mouse SSCs and is required for SSC proliferation in vitro through effects on transcriptome and signaling transduction pathways. | Jinhuan Ou Yiran Li Zhipeng Wang Cheng Jin Kai Li Yan Lu Dingfeng Zou Pengyu Li Mengzhen Li Shiying Miao Linfang Wang Wei Song | 2020 | Chinese Medical Sciences Journal2020，35，1： | 0 |
| 8 | A novel strategy for treating oncogene-mutated tumors by targeting tumor microenvironment and synergistically enhancing anti-PD-1 immunotherapy显示文摘Oncogenes are critical factors in tumorigenesis of diverse cancer types and play essential roles in tumor immune escape.Mutations in Kirsten rat sarcoma viral oncogene homolog(KRAS)and epidermal growth factor receptor(EGFR)are among the most frequent gain-of-function alterations[1].After many years of in-depth research,inhibitors targeting EGFR or KRAS mutations have been successfully developed,however,their clinical benefit is relatively limited,and they will inevitably encounter the challenge of drug resistance.The emergence of resistance is attributed to secondary mutations in driver genes and other complicated factors. | Yingqiang Liu Linjiang Tong Mengge Zhang Qi Zhang Qiupei Liu Fang Feng Yan Li Mengzhen Lai Haotian Tang Yi Chen Meiyu Geng Wenhu Duan Jian Ding Hua Xie | 2024 | Cancer Communications2024，44，3： | 0 |
