| 1 | Three-dimensional paper-like graphene framework with highly orientated laminar structure as binder-free supercapacitor electrode显示文摘A free-standing paper-like three-dimensional graphene framework(3DGF) with orientated laminar structure and interconnected macropores, was obtained by the hard template-directed ordered assembly. As the sacrificial templates, polystyrene(PS) latex spheres were assembled with graphene oxide(GO) to build up a sandwich type composite film, followed by heat removal of which with a simultaneous reduction of GO. The 3DGF exhibited high specific surface area of 402.5 m2/g, controllable pores and mechanical flexibility, which was employed as the binder-free supercapacitor electrode and shows high specific gravimetric capacitance of 95 F/g at 0.5 A/g, with enhanced rate capability in 3 electrode KOH system. | Yidan Gao Yaoyao Zhang Yong Zhang Lijing Xie Xiaoming Li Fangyuan Su Xianxian Wei Zhiwei Xu Chengmeng Chen Rong Cai | 2016 | Journal of Energy Chemistry2016,25,1: | 5 |
| 2 | Recent advances in carbon nanostructures prepared from carbon dioxide for high-performance supercapacitors显示文摘The burgeoning global economy during the past decades gives rise to the continuous increase in fossil fuels consumption and rapid growth of CO_(2) emission,which demands an urgent exploration into green and sustainable devices for energy storage and power management.Supercapacitors based on activated carbon electrodes are promising systems for highly efficient energy harvesting and power supply,but their promotion is hindered by the moderate energy density compared with batteries.Therefore,scalable conversion of CO_(2) into novel carbon nanostructures offers a powerful alternative to tackle both issues:mitigating the greenhouse effect caused by redundant atmospheric CO_(2) and providing carbon materials with enhanced electrochemical performances.In this tutorial review,the techniques,opportunities and barriers in the design and fabrication of advanced carbon materials using CO_(2) as feedstock as well as their impact on the energy-storage performances of supercapacitors are critically examined.In particular,the chemical aspects of various Cv2 conversion reactions are highlighted to establish a detailed understanding for the science and technology involved in the microstructural evolution,surface engineering and porosity control of CO_(2)-converted carbon nanostructures.Finally,the prospects and challenges associated with the industrialization of CO_(2) conversion and their practical application in supercapacitors are also discussed. | Chen Li Xiong Zhang Kai Wang Fangyuan Su Cheng-Meng Chen Fangyan Liu Zhong-Shuai Wu Yanwei Ma | 2021 | Journal of Energy Chemistry2021,30,3: | 4 |

| 4 | Bifunctional flexible electrochromic energy storage devices based on silver nanowire flexible transparent electrodes显示文摘Flexible electrochromic energy storage devices(FECESDs)for powering flexible electronics have attracted considerable attention.Silver nanowires(AgNWs)are one kind of the most promising flexible transparent electrodes(FTEs)materials for the emerging flexible devices.Currently,fabricating FECESD based on AgNWs FTEs is still hindered by their intrinsic poor electrochemical stability.To address this issue,a hybrid AgNWs/Co(OH)_(2)/PEDOT:PSS electrode is proposed.The PEDOT:PSS could not only improve the resistance against electrochemical corrosion of AgNWs,but also work as functional layer to realize the color-changing and energy storage properties.Moreover,the Co(OH)_(2)interlayer further improved the color-changing and energy storage performance.Based on the improvement,we assembled the symmetrical FECESDs.Under the same condition,the areal capacitance(0.8 mF cm^(−2))and coloration efficiency(269.80 cm^(2)C−1)of AgNWs/Co(OH)_(2)/PEDOT:PSS FECESDs were obviously higher than AgNWs/PEDOT:PSS FECESDs.Furthermore,the obtained FECESDs exhibited excellent stability against the mechanical deformation.The areal capacitance remained stable during 1000 times cyclic bending with a 25 mm curvature radius.These results demonstrated the broad application potential of the AgNWs/Co(OH)_(2)/PEDOT:PSS FECESD for the emerging portable and multifunctional electronics. | He Zhang Fangyuan Sun Ge Cao Dongyan Zhou Guofan Zhang Jiayun Feng Shang Wang Fengyu Su Yanqing Tian Yan Jun Liu Yanhong Tian | 2023 | International Journal of Extreme Manufacturing2023,5,1: | 1 |
| 5 | Combined DFT and experiment:Stabilizing the electrochemical interfaces via boron Lewis acids显示文摘The incorporation of boron into carbon material can significantly enhance its capacity performances.However,the origin of the promotion effect of boron doping on electrochemical performances is still unclear,in part due to the inadequate exposure of boron configurations resulting from the complexity of traditional carbon materials.To overcome this issue,herein,a series of boron-doped graphene with highly-exposed boron configurations are prepared by tuning annealing temperature.Then the correlation between boron configurations and the electrochemical performances is investigated.The combination of density-functional theory(DFT)computation and NH3-TPD/Py-FTIR indicates that the BCO_(2)configuration formed on the surface of graphene is easier to accept lone-pair electrons than BC_(2)O and BC_(3)configurations due to the stronger Lewis acidity.Such an electronic structure can effectively reduce the number of unstable electron donors and stabilize the electrochemical interface,which is proved by NMR,and critical for improving the electrochemical performances.Further experiments confirm that the optimized BG800 with the largest amount of BCO_(2)configuration presents ultralow leak current,improved cyclic stability,and better rate performance in SBPBF4/PC.This work would provide an insight into the design of high-performance boron-doped carbon materials towards energy storage. | Zhe-Fan Wang Zonglin Yi Aziz Ahmad Lijing Xie Jing-Peng Chen Qingqiang Kong Fangyuan Su Da-Wei Wang Cheng-Meng Chen | 2021 | Journal of Energy Chemistry2021,30,8: | 1 |

| 8 | Molecular modification of Bacillus stearothermophilus NO_(2) cyclodextrin glucosyltransferase and preparation of α-cyclodextrin显示文摘Cyclodextrin(CD)is produced by the catalysis of starch or starch derivatives by cyclodextrin glucosyltransferase(CGTase),and its yield is mainly limited by the product and reaction specificity of CGTase.In this study,we use CGTase derived from Bacillus stearothermophilus NO_(2),exhibiting high expression levels and good stability for molecular modification.The N353A mutant effectively decreases the hydrolysis activity,and the ratio of the k_(cat) values(cyclization to hydrolysis activity)is 86.46,which is threefold that of the wild type.The E142P mutant effectively enhancesα-CD specificity,which increases the ratio of k_(cat) values(α-CD toβ-CD formation)from 2.18 of the wild-type to 2.42.The N353A/E142P mutant weakens the hydrolysis side reaction and enhancesα-CD specificity,and the proportion ofα-CD products is 53.67%,which is 15.62%higher than that of the wild-type.This research focuses on CGTase reaction and product specificities,which suggest a novel method for the industrial production ofα-CD. | Fangyuan Zuo Lingqia Su Demin Kong Lei Wang Jing Wu Sheng Chen | 2022 | Systems Microbiology and Biomanufacturing2022,2,4: | 1 |
| 9 | Supplementing Qi and activating blood circulation method to treat vertebrobasilar dolichoectasia with posterior circulatory watershed infarction:a case report of two patients显示文摘Vertebrobasilar dolichoectasia(VBD),a rare posterior circulation vascular variant disease,is an important risk factor for many acute cerebrovascular diseases.An insufficient understanding of VBD often leads to misdiagnose.Two cases of VBD that were initially diagnosed as posterior circulation watershed infarction are reported here.Absence of common causes of stroke including hypoperfusion,blood system diseases,carotid and aortic dissection,and eosinophil elevation,the symptoms of the 2 patients met the diagnostic criteria of VBD.Both patients displayed symptoms that were in line with the Traditional Chinese Medicine(TCM)syndrome pattern of'Qi deficiency and blood stasis'.Accordingly,they were comprehensively treated with Supplementing Qi and activating blood circulation method.The clinical manifestations of the 2 patients were remarkably improved and no recurrence of watershed infarction was found in a 1-year follow-up.A detailed medical history and laboratory examination are capable of improving diagnostic accuracy of VBD.TCM treatment based on syndrome identification might be a promising candidate for VBD management. | LI He SU Wenquan LI Shanshan JI Hanrui CHENG Jiangyan CUI Fangyuan TANG Lu ZHOU Li GAO Ying DONG Xinglu | 2023 | Journal of Traditional Chinese Medicine2023,43,4: | 0 |
| 10 | Apios americana Medik flower extract protects high-glucose-treated hepatocytes and Caenorhabditis elegans显示文摘Type 2 diabetes(T2D)is a chronic metabolic disease related to glucose metabolism disorders.Increasing evidences indicate that flavonoids obtained from plants have beneficial effects on T2D.Apios americana Medik,originally cultivated in North America,is rich in flavonoids.In this study,A.americana flower extract(AFE)was purified and flavonoids were identified.The beneficial effects of AFE on glucose metabolism disorders were investigated.Results showed that AFE protected hepatic cells from oxidative stress caused by hyperglycemia and increased glucose consumption and glucose uptake.The AKT pathway was involved in AFE-mediated hypoglycemic action in LO2 cells,accompanied by phosphorylation of FoxO1,Gsk-3βand AMPK.In vivo,AFE protected Caenorhabditis elegans(C.elegans)from oxidative stress under hyperglycemia and restored the expressions of PMK-1 and SKN-1.Furthermore,AFE decreased excessive glucose and lipid accumulation and extended the lifespans of high glucose(HG)treated C.elegans.AFE might be beneficial to decrease glucose metabolism disorders and T2D. | Su Zhou Jiafei Chen Fangyuan Fan Yani Pan Xinyu Feng Lushuang Yu Shuying Gong Xiaodong Zheng Yihong Jiang Qiang Chu | 2022 | Food Bioscience2022,45,1: | 0 |
| 11 | Nitrogen-doped holey graphene nanoscrolls for high-energy and high-power supercapacitors显示文摘Porous structure and heteroatom doping are two key parameters for significantly boosting the capacitive performance of graphene-based materials.Herein,we report a facile approach to prepare onedimensional(ID) nitrogen-doped holey graphene nanoscrolls(NHGNSs) through cold quenching treatment of two-dimensional graphene oxide sheets,followed by thermal annealing in the successive atmosphere of NH3 and air.Benefiting from the synergy of the unique 1D tubular morphology,abundant nanoholes and nitrogen doping,the NHGNSs exhibit a high specific capacitance of 126 F/g at 1 A/g in ionic liquid electrolyte and excellent rate capability with 81% of the capacitance retained at 20 A/g.Furthermore,the fabricated symmetric supercapacitors based on NHGNSs achieve both high energy density of 53.5 Wh/kg at 875 W/kg and high power density of 17.5 kW/kg at 43.4 Wh/kg.The simple synthetic process and superior electrochemical performance suggest the great potential of NHGNSs for supercapacitor application. | Feng Su Shuanghao Zheng Fangyan Liu Xiong Zhang Fangyuan Su Zhong-Shuai Wu | 2021 | Chinese Chemical Letters2021,32,2: | 0 |
| 12 | Utilizing the capacity below 0 V to maximize lithium storage of hard carbon anodes显示文摘Compared with conventional graphite anode,hard carbons have the potential to make reversible lithium storage below 0 V accessible due to the formation of dendrites is slow.However,under certain conditions of high currents and lithiation depths,the irreversible plated lithium occurs and then results in the capacity losses.Herein,we systematically explore the true reversibility of hard carbon anodes below 0 V.We identify the lithiation boundary parameters that control the reversible capacity of hard carbon anodes.When the boundary capacity is controlled below 400 mAh g−1 with current density below 50 mA g−1,no lithium dendrites are observed during the lithiation process.Compared with the discharge cut-off voltage to 0 V,this boundary provides a nearly twice reversible capacity with the capacity retention of 80%after 172 cycles.The results of characterization and finite element model reveal that the large reversible capacity below 0 V of hard carbon anodes is mainly benefited from the dual effect of lithium intercalation and reversible lithium film.After the lithium intercalation,the over-lithiation induces the quick growth of lithium dendrites,worsening the electrochemical irreversibility.This work enables insights of the potentially low-voltage performance of hard carbons in lithium-ion batteries. | Qianlei Liu Liqin Dai Lijing Xie Zonglin Yi Mingxin Song Yafeng Fan Guohua Sun Fangyuan Su Cheng-Meng Chen | 2023 | Particuology2023,,12: | 0 |

| 14 | Trees as hotspots:Using forests,trees,and agroforestry to foster diverse sustainable landscapes显示文摘Forests,trees,and agroforestry(FTA)are ecosystem hotspots.They exemplify the contributions of biodiversity to sustainable and resilient landscapes,green circular economy and to sustainable agriculture and food systems for healthy diets.However,most research on these topics have been performed separately and lack comparison.The International FTA-Kunming Conference'Forests,trees and agroforestry for diverse sustainable landscapes'22nd–24th June 2021,focused on these contributions,brought together scientists NGOs,and policy makers to further the understanding of tree diversity;provided a communication platform for scientists to share their research results;evaluated the role of tree diversity in agroecology and circular agriculture;assessed benefits of landscape restoration;and explored applied research in mountain ecosystems and food security.The goals were to gather evidence that ground the design of solutions that can contribute to the implementation of the post 2020 Global Biodiversity Framework and towards the UN Food Systems Summit,and the overall implementation of the SDGs.This paper summarizes the outcomes of the international FTA Conference in Kunming 2021 and points out the highlights of research involved in six major themes. | Vincent Gitz Jianchu Xu Yuanchang Lu Elaine Springgay Illias Animon Razan Khalifa Al Mubarak Robert Nasi Tony Simons Ranjit Barthakur Ren Wang Jianrong Su Fergus Sinclair Eduardo Somarriba Dossa G.O.Gbadamassi Ramni Jamnadass Christopher JKettle Dengpan Bu Anja Gassner Yves Laumonier Mi Zhou Himlal Baral Fangyuan Hua Peter AMinang Yufu Guo Michael Allen Brady Yanxia Li Peter Mortimer Bin Yang Heng Gui Fiona Worthy Deli Zhai Huafang Chen Huili Li Yufang Su Alexandre Meybeck Fabio Ricci | 2022 | Circular Agricultural Systems2022,2,1: | 0 |
| 15 | MicroRNA-20a-5p regulates the epithelial-mesenchymal transition of human hepatocellular carcinoma by targeting RUNX3显示文摘Background::MicroRNA-20a (miR-20a) is dysregulated in many types of malignancies, including human hepatocellular carcinoma (HCC), but its expression level and functional significance in HCC are still disputed. We aimed to study the role of miR-20a-5p in HCC and its downstream molecular mechanisms.Methods::We used real-time polymerase chain reaction to detect the expression of miR-20a-5p and runt-related transcription factor 3 ( RUNX3) in HCC and paraneoplastic tissue, transfected Huh7 and highly metastatic human hepatocellular carcinoma (MHCC97H) cells. A live cell workstation was used to observe the proliferation and migration of transfected cells. The invasiveness of transfected cells was verified by Transwell assay. Cell apoptosis was detected by flow cytometry. The expression levels of proteins after transfection were measured using simple western immunoblot measurements. Gene expression profiles between HCC and normal samples were obtained from The Cancer Genome Atlas. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment results were processed by the database for annotation, visualization and integrated discovery. Potential target genes of miR-20a-5p were predicted to further investigate how miR-20a-5p regulates epithelial-mesenchymal transition (EMT) in HCC. Results::MiR-20a-5p was significantly highly expressed in HCC tissues, and overexpression of miR-20a-5p significantly promoted HCC cell proliferation, migration, and invasion and inhibited apoptosis in vitro. The protein expression of E-cadherin was decreased and that of vimentin was increased after overexpression of miR-20a-5p in HCC cells. We discovered the intersection of genes from miRDB, miR TarBase, and TargetScan, obtained 397 target genes and finally focused on RUNX3. RUNX3 was not only reduced in HCC specimens but also drastically reduced in HCC cells overexpressing miR-20a-5p. RUNX3 expression decreased with elevated miR-20a-5p, which activated downstream EMT signaling and promoted cell proliferation, migration, and invasion. Conclusions::Since RUNX3 is involved in EMT in HCC, as proven by previous research, our findings provide further evidence for a novel regulatory pathway comprising the miR-20a/RUNX3/EMT axis that upregulates EMT signaling and enhances the migration of HCC cells. | Xianjue Wang Ping Wei Ling Yang Fangyuan Liu Xin Tong Xiaoyu Yang Liya Su | 2022 | Chinese Medical Journal2022,135,17: | 0 |

| 17 | Structural evolution of carbon aerogel microspheres by thermal treatment for high–power supercapacitors显示文摘In this work, a series of carbon aerogel microspheres(CAMs) with tailored pore structures were successfully prepared via a sol-gel method and subsequent heat-treatment at various temperatures from 600 to 1600 ℃. The effects of heat-treatment temperature(HTT) on the CAM microstructure were systematically investigated by physical and chemical characterization. The electrical conductivity increased by up to 250 S/cm and mesopores with high electrolyte accessibility developed in the CAM with increasing HTT. However, the specific surface area(SSA) decreased for HTTs from 1000 to 1600 ℃. The results show that these two factors should be finely balanced for further applications in high power supercapacitors.The CAMs carbonized at 1000 ℃ had the highest SSA(1454 m^2/g), large mesoporous content(20%) and favorable conductivity(71 S/cm). They delivered a high energy density of 38.4 Wh/kg at a power density of 0.17 kW/kg. They retained an energy density of 25.5 Wh/kg even at a high power density of 10.2 kW/kg,and a good rate capability of 84% after 10,000 cycles. This performance is superior to, or at least comparable to, those of most reported carbon materials. | Feng Li Lijing Xie Guohua Sun Fangyuan Su Qingqiang Kong Yufang Cao Xiangyun Guo Chengmeng Chen | 2018 | Journal of Energy Chemistry2018,27,2: | 0 |
