| 1 | Remotely excited Raman optical activity using chiral plasmon propagation in Ag nanowires显示文摘We experimentally investigated remotely excited Raman optical activity(ROA)using propagating surface plasmons in chiral Ag nanowires.Using chiral fmoc-glycyl-glycine-OH(FGGO)molecules,we first studied the local surface plasmon-enhanced ROA.We found that the Raman intensity can be excited by left-and right-circularly polarized lights and that the circular intensity difference(CID)can be significantly enhanced.Second,by selecting vibrational modes with large Raman and ROA intensities that are not influenced by chemical enhancements,we studied remotely excited ROA imaging and the CID of FGGO molecules by propagating a plasmonic waveguide using Ag chiral nanostructures.When laser light was radiated on one of the Ag terminals,the measured CID of the FGG at the other terminal showed little change compared to the local excited CID.Meanwhile,when the laser light was radiated on the Ag nanowires(not on the terminals)and was coupled to the nearby nanoantenna,the CID of the ROA could be manipulated by altering the coupling angle between the Ag nanowires.To directly demonstrate the propagation of ROA along the nanowire and its remote detection,we also measured the remotely excited ROA spectra.Our experimental method has the potential to remotely determine the chirality of molecular structures and the absolute configuration or conformation of a chiral live cell. | Mengtao Sun Zhenglong Zhang Peijie Wang Qiang Li Fengcai Ma Hongxing Xu | 2013 | Light(Science & Applications)2013，2，1： | 7 |
| 2 | BiVO_(4)/TiO_(2) heterojunction with rich oxygen vacancies for enhanced electrocatalytic nitrogen reduction reaction显示文摘The large-scale production of ammonia mainly depends on the Haber-Bosch process,which will lead to the problems of high energy consumption and carbon dioxide emission.Electrochemical nitrogen fixation is considered to be an environmental friendly and sustainable process,but its efficiency largely depends on the activity and stability of the catalyst.Therefore,it is imperative to develop high-efficient electrocatalysts in the field of nitrogen reduction reaction(NRR).In this paper,we developed a BiVO_(4)/TiO_(2) nanotube(BiVO_(4)/TNT)heterojunction composite with rich oxygen vacancies as an electrocatalytic NRR catalyst.The heterojunction interface and oxygen vacancy of BiVO_(4)/TNT can be the active site of N2 dynamic activation and proton transition.The synergistic effect of TiO_(2) and BiVO_(4) shortens the proton transport path and reduces the over potential of chemical reaction.BiVO_(4)/TNT has high ammonia yield of 8.54µg·h^(−1)·cm^(−2) and high Faraday efficiency of 7.70%in−0.8 V vs.RHE in 0.1 M Na_(2)SO_(4) solution. | Yunliang Liu Peiji Deng Ruqiang Wu Ramadan A.Geioushy Yaxi Li Yixian Liu Fengling Zhou Haitao Li Chenghua Sun | 2021 | Frontiers of physics2021，16，5： | 1 |
| 3 | COVID-19-associated gastrointestinal and liver injury:clinical features and potential mechanisms显示文摘Coronavirus disease-2019(COVID-19)is caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).The infection is spreading globally and poses a huge threat to human health.Besides common respiratory symptoms,some patients with COVID-19 experience gastrointestinal symptoms,such as diarrhea,nausea,vomiting,and loss of appetite.SARS-CoV-2 might infect the gastrointestinal tract through its viral receptor angiotensin-converting enzyme 2(ACE2)and there is increasing evidence of a possible fecal–oral transmission route.In addition,there exist multiple abnormalities in liver enzymes.COVID-19-related liver injury may be due to drug-induced liver injury,systemic inflammatory reaction,and hypoxia–ischemia reperfusion injury.The direct toxic attack of SARS-CoV-2 on the liver is still questionable.This review highlights the manifestations and potential mechanisms of gastrointestinal and hepatic injuries in COVID-19 to raise awareness of digestive system injury in COVID-19. | Peijie Zhong Jing Xu Dong Yang Yue Shen Lu Wang Yun Feng Chunling Du Yuanlin Song Chaomin Wu Xianglin Hu Yangbai Sun | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 1 |

| 5 | Generic Seebeck effect from spin entropy显示文摘How magnetism affects the Seebeck effect is an important issue of wide concern in the thermoelectric community but remains elusive.Based on a thermodynamic analysis of spin degrees of freedom on varied d-electron-based ferromagnets and antiferromagnets,we demonstrate that in itinerant or partially itinerant magnetic compounds there exists a generic spin contribution to the Seebeck effect over an extended temperature range from slightly below to well above the magnetic transition temperature.This contribution is interpreted as resulting from transport spin entropy of(partially)delocalized conducting d electrons with strong thermal spin fluctuations,even semiquantitatively in a single-band case,in addition to the conventional diffusion part arising from their kinetic degrees of freedom.As a highly generic effect,the spin-dependent Seebeck effect might pave a feasible way toward efficient“magnetic thermoelectrics.” | Peijie Sun K.Ramesh Kumar Meng Lyu Zhen Wang Junsen Xiang Wenqing Zhang | 2021 | The Innovation2021，2，2： | 1 |
| 6 | Large transverse thermoelectric figure of merit in a topological Dirac semimetal显示文摘The Seebeck effect encounters a few fundamental constraints hindering its thermoelectric(TE)conversion efficiency.Most notably,there are the charge compensation of electrons and holes that diminishes this effect,and the Wiedemann-Franz(WF)law that makes independent optimization of the corresponding electrical and thermal conductivities impossible.Here,we demonstrate that in the topological Dirac semimetal Cd3As2 the Nernst effect,i.e.,the transverse counterpart of the Seebeck effect,can generate a large TE figure of merit zNT.At room temperature,zNT≈0.5 in a small field of 2 T and it significantly surmounts its longitudinal counterpart for any field.A large Nernst effect is generically expected in topological semimetals,benefiting from both the bipolar transport of compensated electrons and holes and their high mobilities.In this case,heat and charge transport are orthogonal,i.e.,not intertwined by the WF law anymore.More importantly,further optimization of zNT by tuning the Fermi level to the Dirac node can be anticipated due to not only the enhanced bipolar transport,but also the anomalous Nernst effect arising from a pronounced Berry curvature.A combination of the topologically trivial and nontrivial advantages promises to open a new avenue towards high-efficient transverse thermoelectricity. | JunSen Xiang SiLe Hu Meng Lyu WenLiang Zhu ChaoYang Ma ZiYu Chen Frank Steglich GenFu Chen PeiJie Sun | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，3： | 0 |
| 7 | Application of traditional Chinese therapy in sports medicine显示文摘Chinese herbs have been used as dietary supplements to improve exercise performance.However,evidence-based studies for the use of Chinese herbs in sports remain scarce.Traditional Chinese therapy(TCT),a form of traditional Chinese non-pharmacological intervention,has remained in use for thousands of years in sports medicine.TCT is beneficial for sports injuries and in enhancing skill development,and is becoming increasingly popular among athletes,fitness enthusiasts,and individuals who regularly exercise.The therapeutic effects of TCT have been demonstrated by clinical and experimental studies,but using these modalities still is associate with potentially adverse effects.Further well-designed studies are necessary to confirm the efficacy of TCT in sports medicine.This review aims to summarize the application of TCT,discuss the issues surrounding TCT clinical research,and provide suggestions for applying traditional Chinese methods in the field of sports medicine. | Liang Kang Peijie Liu Aishi Peng Bingxin Sun Yumei He Zenghao Huang Minjia Wang Yushi Hu Benxiang He | 2021 | Sports Medicine and Health Science2021，3，1： | 0 |
| 8 | Characteristics of the three-dimensional deep electrical structure in the Helan Mountains-Yinchuan Basin and its geodynamic implications显示文摘Located in the north segment of the North-South seismic belt where the Alxa block(AB)and the Ordos block(OB)contact,the Helan Mountains-Yinchuan Basin(HLM-YCB)constitutes a typical normal faulting basin-mountain structure on the Chinese mainland.The 1739 M8.0 Pingluo earthquake occurred in the Yinchuan fault depression basin with such a basinmountain structure.Data on five magnetotelluric profiles encompassing distinct segments of the HLM-YCB were utilized for three-dimensional(3D)joint inversion in order to collect fine 3D electrical structure information at a crustal and upper mantle scale across the entire region.The electrical structure between the main blocks in the HLM-YCB and adjacent areas is characterized by east-west horizontal blocks OB,YCB,and HLM,which are divided by the Yellow River fault(F5)with the HLM eastern piedmont fault(F2)as electrical boundary zones on the east and west sides.The two main block units,AB and OB,exhibit an obvious layered resistivity structure.Besides,the HLM-YCB is characterized by a typical basin-mountain structure with the mountains as a high-resistivity body and the basin as a low-resistivity body,and in the northern YCB a large-scale lowresistivity structure exists,extending to the upper mantle,probably derived from the upwelling of mantle-derived materials.It is speculated from a combination of recent 3D crustal movement field information and other data that the HLM-YCB is an active tectonic zone formed via regional tensile action.The formation of the HLM-YCB lies in the interaction of the Tibetan Plateau(TP),AB,and OB and abnormal mantle activities beneath the YCB.The HLM-YCB reflects the joint action of upwelling and diffluence caused by the underplating of hot materials from the deep mantle with gravity and the redistribution of regional tectonic stress on the earth’s surface,which may be the main dynamic reason for the 1739 M8.0 Pingluo earthquake. | Lingqiang ZHAO Xiangyu SUN Yan ZHAN Jing HAN Haibo YANG Peijie WANG Xuehua LIU | 2023 | Science China Earth Sciences2023，66，3： | 0 |
| 9 | Flavor changes in Lentinus Edodes enzymatic hydrolysate maillard reaction products with different sugars by gas chromatography‐ion mobility spectrometry显示文摘The characteristic flavor of the enzymatic hydrolysate of Lentinus edodes,which was involved in the Maillard reaction by xylose,fructose,glucose,sucrose,mannose,maltose,vitamin C(VC)and L-arabinose,was determined and analyzed by gas chromatography-ion mobility spectroscopy(GC-IMS).The characteristic flavor fingerprints of Maillard reaction products(MRPs)of L.edodes enzymatic hydrolysate were constructed.The differences in the characteristic flavors of Maillard reaction with different reducing sugars and VC were compared.The main characteristic flavor,characteristic peak,characteristic marker substance and content were determined,a principal component analysis(PCA)of volatile organic compounds(VOCs)was carried out.The results showed that there were 42 kinds of monomers and some dimers of volatile compounds in the samples including 17 aldehydes,5 alcohols,7 ketones,2 esters,2 acids,7 other compounds and 2 ethers.The volatile VOCs of the sample with added sucrose,VC and L-arabinose were significantly higher than those of the enzymatic hydrolysate of L.edodes.After the Maillard reaction,the flavor of the hydrolysate was significantly improved,and the main components changed significantly. | Wenjia Cui Peiji Liu Houli Liu Yifei Sun Wenliang Wang | 2023 | Journal of Future Foods2023，3，1： | 0 |
| 10 | 固体颗粒对喷流流场及底部热环境影响规律研究显示文摘Compared with using liquid rocket engines,there are a lot of high-temperature solid particles in the solid-liquid bundled rocket,which make the rocket base thermal environment worse.In order to study the influence of high-temperature solid particles on the base thermal environment,firstly,the effect of particle diameter on the jet distribution and the thermal environment in a single solid motor jet was analyzed using a numerical simulation method,and the results were compared with those of a ground test.Further,the effects of high-temperature solid particles on the jet and the thermal environment of the solid-liquid bundled rocket were analyzed and compared with flight data.The results show that high-temperature solid particles can increase the jet temperature and reduce the jet velocity.The larger the particle diameter,the greater the impact on the jet core temperature.The role of high-temperature solid particles cannot be ignored in the study of the base thermal environment. | ZHANG Liang YAN Li SUN Peijie YANG Fan WANG Heping REN Jie | 2022 | Aerospace China2022，23，2： | 0 |
| 11 | Quantum phase transition and destruction of Kondo effect in pressurized SmB6显示文摘SmB_6 has been a well-known Kondo insulator for decades, but recently attracts extensive new attention as a candidate topological system. Studying SmB_6 under pressure provides an opportunity to acquire the much-needed understanding about the effect of electron correlations on both the metallic surface state and bulk insulating state. Here we do so by studying the evolution of two transport gaps(low temperature gap E_l and high temperature gap E_h) associated with the Kondo effect by measuring the electrical resistivity under high pressure and low temperature(0.3 K) conditions. We associate the gaps with the bulk Kondo hybridization, and from their evolution with pressure we demonstrate an insulator-tometal transition at ~4 GPa. At the transition pressure, a large change in the Hall number and a divergence tendency of the electron-electron scattering coefficient provide evidence for a destruction of the Kondo entanglement in the ground state. Our results raise the new prospect for studying topological electronic states in quantum critical materials settings. | yazhou zhou qi wu priscila f.s.rosa rong yu jing guo wei yi shan zhang zhe wang honghong wang shu cai ke yang aiguo li zheng jiang shuo zhang xiangjun wei yuying huang peijie sun yi-feng yang zachary fisk qimiao si zhongxian zhao liling sun | 2017 | Science Bulletin2017，62，21： | 0 |
| 12 | Performance analysis of cogeneration systems based on micro gas turbine(MGT),organic Rankine cycle and ejector refrigeration cycle显示文摘In this paper,the operation perfonnance of three novel kinds of cogeneration systems under design and off-design condition was investigated.The systems are MGT(micro gas turbine)+ORC(organic Rankine cycle)for electricity demand,MGT+ERC(ejector refrigeration cycle)for electricity and cooling demand,and MGT+ORC+ERC for electricity and cooling demand.The effect of 5 different working fluids on cogeneration systems was studied.The results show that under the design condition,when using R600 in the bottoming cycle,the MGT+ORC system has the lowest total output of 117.1 kW with a thermal efficiency of 0.334,and the MGT+ERC system has the largest total output of 142.6 kW with a thermal efficiency of 0.408.For the MGT+ORC+ERC system,the total output is between the other two systems,which is 129.3 kW with a thermal efficiency of 0.370.For the effect of different working fluids,R123 is the most suitable working fluid for MGT+ORC with the maximum electricity output power and R600 is the most suitable working fluid for MGT+ERC with the maximum cooling capacity,while both R600 and R123 can make MGT+ORC+ERC achieve a good comprehensive performance of refrigeration and electricity.The thermal efficiency of three cogeneration systems can be effectively improved under oredesign condition because the bottoming cycle can compensate for the power decrease of MGT.The results obtained in this paper can provide a reference for the design and operation of the cogeneration system for distributed energy systems(DES). | Zemin BO Kai ZHANG Peijie SUN Xiaojing LV Yiwu WENG | 2019 | Frontiers in Energy2019，13，1： | 0 |
