| 1 | In situ plasmonic optical fiber detection of the state of charge of supercapacitors for renewable energy storage显示文摘In situ and continuous monitoring of electrochemical activity is key to understanding and evaluating the operation mechanism and efficiency of energy storage devices.However,this task remains challenging.For example,the present methods are not capable of providing the real-time information about the state of charge(SOC)of the energy storage devices while in operation.To address this,a novel approach based on an electrochemical surface plasmon resonance(SPR)optical fiber sensor is proposed here.This approach offers the capability of in situ comprehensive monitoring of the electrochemical activity(the electrode potential and the SOC)of supercapacitors(used as an example).The sensor adopted is a tilted fiber Bragg grating imprinted in a commercial single-mode fiber and coated with a nanoscale gold film for high-efficiency SPR excitation.Unlike conventional“bulk”detection methods for electrode activity,our approach targets the“localized”(sub-μm-scale)charge state of the ions adjacent to the electrode interface of supercapacitors by monitoring the properties of the SPR wave on the fiber sensor surface located adjacent to the electrode.A stable and reproducible correlation between the real-time charge–discharge cycles of the supercapacitors and the optical transmission of the optical fiber has been found.Moreover,the method proposed is inherently immune to temperature cross-talk because of the presence of environmentally insensitive reference features in the optical transmission spectrum of the devices.Finally,this particular application is ideally suited to the fundamental qualities of optical fiber sensors,such as their compact size,flexible shape,and remote operation capability,thereby opening the way for other opportunities for electrochemical monitoring in various hard-to-reach spaces and remote environments. | Jiajie Lao Peng Sun Fu Liu Xuejun Zhang Chuanxi Zhao Wenjie Mai Tuan Guo Gaozhi Xiao Jacques Albert | 2018 | Light(Science & Applications)2018，7，1： | 8 |
| 2 | Short-term propamocarb exposure induces hepatic metabolism disorder associated with gut microbiota dysbiosis in adult male zebrafish显示文摘Propamocarb (PM) is a pesticide that is widely used to protect cucumbers and other plants from downy mildew.Recently,some studies indicated that PM exposure had potential toxic effects in animals.In this study,adult male zebrafish were exposed to 100 and 1000 μg/l PM for 7 days to assess its effects on metabolism and the gut microbiota.We observed a significant decrease in triglyceride (TG) in the livers of zebrafish that were exposed to 1000 μg/l PM for 7 days.At the same time,some genes related to glycolysis and lipid metabolism in the livers of zebrafish,including hexokinase-1 (HK1),pyruvate kinase (PK),acyi-CoA oxidase (Aco),peroxisome proliferator activated receptor alpha (Ppar-α),apolipoprotein A-Ⅳ-like (Apo),Acetyl CoA carboxylase-1 (Acc1),diacylglycerol acyltransferase (Dgat),and fatty acid synthase (Fas),were also decreased significantly after PM exposure.Based on GC-MS metabolomics analysis,a total of 48 metabolites changed significantly in the 1000 μg/l PM treatment group in comparison with the control group.These altered metabolites were mainly associated with the glycolysis,amino acid metabolism,and lipid metabolism pathways.Interestingly,we further found that the 1000 μg/l PM treatment group also showed significant elevations in Proteobacteria,Bacteroidetes,and Firmicutes at the phylum level.Sequencing of the 16S rRNA gene in the V3-V4 region also showed a significant change in the abundance and diversity of the gut microbiota in the 1000 μg/l PM treatment group.Our results indicated that exposure to PM for a short time could induce hepatic metabolic disorders and gut microbiota dysbiosis in adult male zebrafish. | Rui Zhang Zihong Pan Xiaoyu Wang Manlu Shen Jiajie Zhou Zhengwei Fu Yuanxiang Jin | 2019 | Acta Biochimica et Biophysica Sinica2019，51，1： | 6 |
| 3 | Simulation of Coupling Process of Flexible Needle Insertion into Soft Tissue Based on ABAQUS显示文摘In order to get to the desired target inside the body,it is essential to investigate the needle-tissue coupling process and calculate the tissue deformation.A cantilever beam model is presented to predicting the deflection and bending angle of flexible needle by analyzing the distribution of the force on needle shaft during the procedure of needle insertion into soft tissue.Furthermore,a finite element(FE)coupling model is proposed to simulate the needle-tissue interactive process.The plane and spatial models are created to relate the needle and tissue nodes.Combined with the cantilever beam model and the finite element needle-tissue coupling model,the simulation of needle-tissue interaction was carried out by the ABAQUS software.The comparing experiments are designed to understand the needle-tissue interactions,by which the same points in the experiments and simulation are compared and analyzed.The results show that the displacements in x and z directions in the simulation can accord with the experiments,and the deformation inside the tissue mainly occurs in the axial direction.The study is beneficial to the robot-assisted and virtual needle insertion procedure,and to help the physicians to predict the inside tissue deformation during the treatments. | Linze Wang Dedong Gao Jiajie Fu Yuzhou Luo Shijian Zhao | 2020 | Computers, Materials & Continua2020，，8： | 3 |
| 4 | Recent advances in crystalline carbon nitride for photocatalysis显示文摘Semiconductor photocatalytic technology has become one of the most important means to solve the current energy shortage and environmental pollution. Compared with the traditional photocatalysts, graphite carbon nitride has a wider range of light-harvesting and more stable physical and chemical properties. However, traditional thermally induced polymerization of nitrogen-containing precursors produces the melon-based carbon nitride solids with an amorphous or semi-crystalline structure, resulting in low conductivity and moderate photocatalytic activity. Recently, crystalline carbon nitride has attracted more and more attention in improving photocatalytic performance. Some significant progress regarding crystalline carbon nitride for the preparation of solar-fuel and environmental purification has also been made.This review describes the recent advances in the design and synthesis of crystalline carbon nitride photocatalysts. A brief description of the unique physical and chemical properties of crystalline carbon nitride was given. Later, the synthetic and modification strategies are being introduced. Then, the photocatalytic application of crystalline carbon nitride was discussed, mainly including photocatalytic H2 production,photocatalytic CO2 reduction, and photocatalytic degradation of pollutants. Finally, the challenges and future directions of crystalline carbon nitride photocatalysts are briefly introduced. | Jingjun Liu Wei Fu Yulong Liao Jiajie Fan Quanjun Xiang | 2021 | Journal of Materials Science & Technology2021，，32： | 2 |
| 5 | Abnormal anti-oxidation behavior of hexagonal boron nitride grown on copper显示文摘Atomic-layered hexagonal boron nitride(hBN)is expected to be the best two-dimensional(2D)anti-oxidation layer on metals for its incomparable impermeability,insulativity,and stability,as well as the progressive bottom-up growth techniques to ensure fast coating on metal surface in large area.However,its real anti-oxidation ability in practice is found to be unsatisfactory and nonuniform,and the main obstacle to achieving ideal anti-oxidation performance lies in unclear anti-oxidation behavior at special interface between 2D hBN and three-dimensional(3D)metals.Herein,system of monolayer hBN grown on copper(Cu)foils with various lattice orientations was grown to investigate the anti-oxidation behavior of different interlayer configurations.By using structural characterizations together with analysis of topography,we surprisingly found that stronger interlayer coupling led to worse anti-oxidation performance owing to fast diffusion of O2 through higher hBN corrugations generated at the commensurate hBN/Cu(111)configuration.In view of this,we developed the approach of cyclic reannealing that can effectively flatten corrugations and steps,and therefore improve the anti-oxidation performance to a great extent.This work provides a more indepth understanding of anti-oxidation behavior of 2D materials grown on 3D metals,and a practical method to pave the way for its large-scale applications in future. | Li Wang Jiajie Qi Shuai Zhang Mingchao Ding Wei Wei Jinhuan Wang Zhihong Zhang Ruixi Qiao Zhibin Zhang Zehui Li Kehai Liu Ying Fu Hao Hong Can Liu Muhong Wu Wenlong Wang Jun He Yi Cui Qunyang Li Xuedong Bai Kaihui Liu | 2022 | Nano Research2022，15，8： | 0 |
| 6 | Construction of N,O co-doped carbon anchored with Co nanoparticles as efficient catalyst for furfural hydrodeoxygenation in ethanol显示文摘Hydrodeoxygenation of furfural(FF)into 2-methylfuran(MF)is a significant biomass utilization route.However,designing efficient and stable non-noble metal catalyst is still a huge challenge.Herein,we reported the N,O co-doped carbon anchored with Co nanoparticles(Co-SFB)synthesized by employing the organic ligands with the target heteroatoms.Raman,electron paramagnetic resonance(EPR),electrochemical impedance spectroscopy(EIS),and X-ray photoelectron spectroscopy(XPS)characterizations showed that the co-doping of N and O heteroatoms in the carbon support endows Co-SFB with enriched lone pair electrons,fast electron transfer ability,and strong metal-support interaction.These electronic properties resulted in strong FF adsorption as well as lower apparent reaction activation energy.At last,the obtained N,O co-doped Co/C catalyst showed excellent catalytic activity(nearly 100 mol%FF conversion and 94.6 mol%MF yield)and stability for in-situ dehydrogenation of FF into MF.This N,O co-doping strategy for the synthesis of highly efficient catalytic materials with controllable electronic state will provide an excellent opportunity to better understand the structure-function relationship. | Hui Yang Hao Chen Wenhua Zhou Haoan Fan Chao Chen Yixuan Sun Jiaji Zhang Sifan Wang Teng Guo Jie Fu | 2023 | Journal of Energy Chemistry2023，，3： | 0 |
| 7 | Mapping the glaucousness suppressor Iw1 from wild emmer wheat “PI 481521”显示文摘Many species of Triticeae display a glaucous phenotype. In wheat, glaucousness/waxiness on spikes, leaves and shoots is controlled by wax production genes(W loci) and epistatic inhibitors(Iw loci). In this study, a suppressor of glaucousness from wild emmer wheat(Triticum turgidum ssp. dicoccoides) accession 'PI 481521' was investigated in a pair of durum(T. turgidum ssp. durum cv. 'Langdon', LDN)—wild emmer wheat chromosome substitution lines, LDN and 'LDNDIC521-2B'. Genetic analysis revealed that the non-glaucous phenotype of LDNDIC521-2Bwas controlled by the dominant glaucous suppressor Iw1 on the short arm of chromosome 2B. In total, 371 2B-specific marker differences were identified between LDN and LDNDIC521-2B. The location of the Iw1 gene was mapped using an F2 population that stemmed from LDN and LDNDIC521-2B, generating a partial linkage map that included 19 simple sequence repeats(SSR) and ten gene-based markers. On the current map, the Iw1 gene was located within the Xgwm614–BE498111 interval, and cosegregated with BQ788707,CD893659, CD927782, CD938589, and Xbarc35. Mapping of Iw1 in LDNDIC521-2B, a publically accessible and widely distributed line, will provide valuable information for marker-assisted selection of the agronomically important trait of glaucousness. | Zongchang Xu Cuiling Yuan Jirui Wang Daolin Fu Jiajie Wu | 2015 | The Crop Journal2015，3，1： | 0 |
| 8 | Correlating the Interfacial Polar-Phase Structure to the Local Chemistry in Ferroelectric Polymer Nanocomposites by Combined Scanning Probe Microscopy显示文摘Ferroelectric polymer nanocomposites possess exceptional electric properties with respect to the two otherwise uniform phases,which is commonly attributed to the critical role of the matrix-particle interfacial region.However,the structure-property correlation of the interface remains unestablished,and thus,the design of ferroelectric polymer nanocompos-ite has largely relied on the trial-and-error method.Here,a strategy that combines multi-mode scanning probe microscopy-based electrical charac-terization and nano-infrared spectroscopy is developed to unveil the local structure-property correlation of the interface in ferroelectric polymer nano-composites.The results show that the type of surface modifiers decorated on the nanoparticles can significantly influence the local polar-phase content and the piezoelectric effect of the polymer matrix surrounding the nano-particles.The strongly coupled polar-phase content and piezoelectric effect measured directly in the interfacial region as well as the computed bonding energy suggest that the property enhancement originates from the formation of hydrogen bond between the surface modifiers and the ferroelectric polymer.It is also directly detected that the local domain size of the ferroelectric polymer can impact the energy level and distribution of charge traps in the interfacial region and eventually influence the local dielectric strength. | Jiajie Liang Shaojie Wang Zhen Luo Jing Fu Jun Hu Jinliang He Qi Li | 2023 | Nano-Micro Letters2023，15，1： | 0 |
| 9 | Creating large EMS populations for functional genomics and breeding in wheat显示文摘Wheat germplasm is a fundamental resource for basic research,applied studies,and wheat breeding,which can be enriched normally by several paths,such as collecting natural lines,accumulating breeding lines,and introducing mutagenesis materials.Ethyl methane sulfonate(EMS)is an alkylating agent that can effectively introduce genetic variations in a wide variety of plant species.In this study,we created a million-scale EMS population(MEP)that started with the Chinese wheat cultivars‘Luyan 128’,‘Jimai 38’,‘Jimai 44’,and‘Shannong 30’.In the M1 generation,the MEP had numerous phenotypical variations,such as>3,000 chlorophyll-deficient mutants,2,519 compact spikes,and 1,692 male sterile spikes.There were also rare mutations,including 30 independent tillers each with double heads.Some M1 variations of chlorophyll-deficiency and compact spikes were inheritable,appearing in the M2 or M3 generations.To advance the entire MEP to higher generations,we adopted a single-seed descendent(SSD)approach.All other seed composites of M2 were used to screen other agronomically important traits,such as the tolerance to herbicide quizalofop-P-methyl.The MEP is available for collaborative projects,and provides a valuable toolbox for wheat genetics and breeding for sustainable agriculture. | Wenqiang Wang Xizhen Guan Yong Gan Guojun Liu Chunhao Zou Weikang Wang Jifa Zhang Huifei Zhang Qunqun Hao Fei Ni Jiajie Wu Lynn Epstein Daolin Fu | 2024 | Journal of Integrative Agriculture2024，23，2： | 0 |

| 11 | Percent body fat,but not body mass index,is associated with cardiometabolic risk factors in children and adolescents显示文摘Background:The epidemic of overweight and obesity has become a worldwide public health problem.Cardiometabolic diseases may originate in childhood.We investigated the association between percent body fat(PBF)measured by the bioelectrical impedance assay and cardiometabolic risk(CMR)in pediatrics.Methods:This cross-sectional study involved 3819 subjects(6-17 years old)in Shanghai.We assessed the association between PBF and body mass index(BMI)with multiple CMR factors.We examined the risk for cardiometabolic abnormalities attributable to overweight and obesity based on age-and sexspecific PBF Z-scores and BMI Z-scores,respectively.Results:PBF,but not BMI,was positively associated with multiple CMR factors in males and females except for total cholesterol in females(all p<0.05).Compared with the non-overweight group based on PBF,overweight and obese subjects had increasingly higher odds ratio of dyslipidemia(2.90(1.99-4.23),4.59(2.88-7.32)for males and 1.82(1.20-2.75),2.46(1.47-4.11)for females)and elevated blood pressure(BP)(3.26(2.35-4.51),4.55(2.92-7.09)for males and 1.59(1.07-2.34),3.98(2.27-6.17)for females).Obesity females showed a higher likelihood for hyperglycemia(2.19(1.24-3.84))than non-overweight females.In both sexes,the predictive effect of PBF on dyslipidemia and elevated BP in adolescents was better than that in children.For hyperglycemia,the predictive effect of PBF was better in male adolescents and female children.There was no risk difference for cardiometabolic abnormalities attributable to BMI-based obesity categories.Conclusions:PBF but not BMI was associated with CMR.Overweight and obesity categories based on PBF had an increased risk for cardiometabolic abnormalities in children and adolescents. | Xin He Zhenni Zhu Jiajie Zang Zhengyuan Wang Ping Liao Wenjing Wang Yan Shi Chen Fu | 2023 | Chronic Diseases and Translational Medicine2023，9，2： | 0 |
| 12 | Si-based InGaAs photodetectors on heterogeneous integrated substrate显示文摘In this paper,InGaAs p-i-n photodetectors(PDs)on an InP/SiO2/Si(InPOI)substrate fabricated by ion-slicing technology are demonstrated and compared with the identical device on a commercial InP substrate.The quality of epitaxial layers on the InPOI substrate is similar to that on the InP substrate.The photo responsivities of both devices measured at 1.55μm are comparable,which are about 0.808-0.828 A W^(-1).Although the dark current of PD on the InPOI substrate is twice as high as that of PD on the InP substrate at 300 K,the peak detectivities of both PDs are comparable.In general,the overall performance of the InPOI-based PD is comparable to the InP-based PD,demonstrating that the ion-slicing technology is a promising route to enable the highquality Si-based InP platform for the full photonic integration on a Si substrate. | Chaodan Chi Jiajie Lin Xingyou Chen Chengli Wang Ziping Li Liping Zhang Zhanglong Fu Xiaomeng Zhao Hua Li Tiangui You Li Yue Jiaxiang Zhang Niefeng Sun Peng Gao Robert Kudrawiec Shumin Wang Xin Ou | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，6： | 0 |
| 13 | Ag_(2)S Quantum Dots Decorated on Porous Cubic-CdS Nanosheets-assembled Flowers for Photocatalytic CO_(2)Reduction显示文摘The production of renewable fossil fuels such as CH_(4) and CO by photocatalytic CO_(2)reduction has attracted more and more attention.However,single photocatalyst is less efficient for photocatalytic reduction of CO_(2)due to the fast recombination of photogenerated electron pairs.Herein,we successfully prepare CdS-Ag_(2)S composite by assembling the Ag_(2)S QDs cocatalyst on the surface of CdS nanosheet-assembled flower through oil-bath solvothermal method.This composite is prepared through a simple self-assembly strategy using cadmium chloride,ammonia and thiourea as precursors of the CdS nanosheet-assembled flower and silver nitrate and 3-mercaptopropionic acid as the precursors of Ag_(2)S QDs.The average diameter of Ag_(2)S QDs is apparently 6.0 nm.The light absorption edge of the composite is at around 560 nm,with the corresponding band gap at 2.14 eV.The CdS-Ag_(2)S QDs composite with 5 wt%Ag_(2)S QDs loaded achieves CO evolution rate of 16.6μmol·g^(-1)·h^(-1)without noble-metal cocatalysts.This strengthened photocatalytic performance and photocatalytic stability were attributed to the energy band broadening of Ag_(2)S QDs caused by quantum size effect and the large specific surface area due to the assembled flower.The mechanism underlying the enhanced photocatalytic CO_(2)reduction activity is further proposed.This study demonstrates that semiconductor-based quantum dots are strong candidates for excellent cocatalysts in photocatalysis. | Wei Fu Jiajie Fan Quanjun Xiang | 2022 | Chinese Journal of Structural Chemistry2022，41，6： | 0 |
| 14 | Highly Stretchable Shape Memory Self-Soldering Conductive Tape with Reversible Adhesion Switched by Temperature显示文摘With practical interest in the future applications of next-generation electronic devices,it is imperative to develop new conductive interconnecting materials appropriate for modern electronic devices to replace traditional rigid solder tin and silver paste of high melting temperature or corrosive solvent requirements.Herein,we design highly stretchable shape memory self-soldering conductive(SMSC)tape with reversible adhesion switched by temperature,which is composed of silver particles encapsulated by shape memory polymer.SMSC tape has perfect shape and conductivity memory property and anti-fatigue ability even under the strain of 90%.It also exhibits an initial conductivity of 2772 S cm^(−1) and a maximum tensile strain of~100%.The maximum conductivity could be increased to 5446 S cm^(−1) by decreasing the strain to 17%.Meanwhile,SMSC tape can easily realize a heating induced reversible strong-to-weak adhe-sion transition for self-soldering circuit.The combination of stable conductivity,excellent shape memory performance,and temperature-switching reversible adhesion enables SMSC tape to serve two functions of electrode and solder simultaneously.This provides a new way for conductive interconnecting materials to meet requirements of modern electronic devices in the future. | Mengyan Wang Quan Zhang Yiwen Bo Chunyang Zhang Yiwen Lv Xiang Fu Wen He Xiangqian Fan Jiajie Liang Yi Huang Rujun Ma Yongsheng Chen | 2021 | Nano-Micro Letters2021，13，8： | 0 |
