| 1 | Analysis of genetic alterations identifies the frequent mutation of GNAS in colorectal laterally spreading tumors显示文摘Dear Editor,Colorectal cancer(CRC)is among the most commonly diagnosed cancer and the leading cause of cancer-related death worldwide[1].Most CRCs develop from adenomas.Laterally spreading tumors(LSTs)are non-polypoid superficial colorectal neoplasms(CRNs)that are larger than 1 cm and typically extend laterally along the luminal wall.Based on surface morphology,it can be classified into a granular or nongranular type.The pathological morphology of LST manifests only as adenoma or with cancer.Recent studies have characterized 45-79%of LSTs as high-grade intraepithelial neoplasia(HGIN)or submucosal invasion;and the risk of submucosal invasion increases with lesion size[2].Hence,LST is considered a precancerous CRC lesion.Patients with LSTs are usually asymptomatic and diagnosis typically occurs during physical examinations or screening colonoscopy. | Lei Pan Junsheng Chen Chaojun Zhu Lu Han Aimin Li Side Liu | 2020 | Cancer Communications2020，40，11： | 3 |
| 2 | The effect of electrolyte additives on the rate performance of hard carbon anode at low temperature for lithium-ion capacitor显示文摘Lithium-ion capacitor(LIC),which combines the advantages of lithium-ion battery(LIB)and electrical double layer capacitor(EDLC),has a rapid development during last decade,however,the poor low temperature performance still limits its application.In this paper,three electrolyte additives including vinylene carbonate(VC),fluoroethylene carbonate(FEC)and 1,3,2-dioxathiolane 2,2-dioxide(DTD)have been utilized and their effects on the rate performance of hard carbon(HC)anode of LIC at various temperatures ranging from 25℃ to-40℃ have been well evaluated.The cell containing FEC shows the best rate performance at various temperatures and has the charge and discharge capability even at-40℃.For HC anode,the charge transfer impedance(R_(CT))increases exponentially at low temperature,while the equivalent series resistance(Rs)and the impedance of solid electrolyte interface(SEI)increase relatively few.At low temperatures,the effect of FEC may be mainly reflected in its effect on the charge transfer process. | Jianmin Yuan Nan Qin Yanyan Lu Liming Jin Junsheng Zheng Jim P.Zheng | 2022 | Chinese Chemical Letters2022，33，8： | 2 |

| 6 | Higher Harmonics in Free Electron Laser with a Two-Wavenumber Plane Wiggler Magnetic Field显示文摘The higher harmonics of the free electron laser(FEL)with a two-wavenumber plane wiggler magnetic field,which may induce a lot of higher harmonics,are investigated.Using a two-wavenumber wiggler comprised of two separate periodicities,k_(ω)and k_(ω)+Δk,numerical simulations show that the higher harmonic may be amplified and the first harmonic may be suppressed in this kind of FEL with an optimized parameterΔk.The coupling coefficient and gain coefficient in low-gain regime of the harmonic are also obtained. | LU Bo YANG Zhonghai LIU Shenggang YU Junsheng | 1993 | Chinese Physics Letters1993，10，4： | 1 |
| 7 | Influence of Structural Parameters of Turbocharger Floating Bearing on Its Dynamic Characteristic Coefficients显示文摘The structure parameters in an actual industrial production have a great influence on the coefficient of supercharger floating bearing dynamic characteristics,but there has been little systematic study so far.In this paper,the influence of structural parameters of the turbocharger floating bearing on its dynamic characteristic coefficientsis systematically investigated based on the theories of hydrodynamic lubrication and tribology.The influence of clearance ratio on eccentricity and the influence of internal to external radius ratios,and Sommerfeld number were analyzed.A new formula of responding characteristics of the oil film force caused by the displacement or velocity disturbance was deduced near an equilibrium in the steady state.Applying the newly developed formula,the dynamic characteristic was studied for floating bearings.Regularity for change of oil film stiffness and damping was analyzed with the structural parameters of floating bearing such as radius ratios and eccentricity.It has been found that the clearance ratio increases with eccentricity when the radius ratio is unchanged.The eccentricity decreases with the internal to external radius ratio of floating rings when the clearance ratio is constant.The absolute value of total principal stiffness and total main damping decrease with the clearance ratio and radius ratio of floating rings when the total cross damping is stable.The results and findings in this paper can contribute to nonlinear dynamics designs of turbocharger rotor-bearing systems. | Junsheng Zhao Yuantong Gu Shengxian Yi Xuelong Lu | 2017 | Journal of Beijing Institute of Technology2017，26，2： | 1 |
| 8 | Comparative Study on Wire-Arc Additive Manufacturing and Conventional Casting of Al–Si Alloys:Porosity,Microstructure and Mechanical Property显示文摘Here,we compare the porosity,microstructure and mechanical property of 4047 Al–Si alloys prepared by wire-arc additive manufacturing(WAAM)and conventional casting.X-ray microscopy reveals that WAAM causes a higher volume fraction of gas pores in comparison with conventional casting.Effective refi nements ofα-Al dendrites,eutectic Si particles and Ferich intermetallic compounds are achieved by WAAM,resulting from its rapid solidifi cation process.Both ultimate tensile strength(UTS,up to 205.6 MPa)and yield stress(YS,up to 98.0 MPa)are improved by WAAM at the expense of elongation after fracture.The mechanical property anisotropy between scanning direction and build direction is minimal for alloys via WAAM.Additional microstructure refi nement and strength enhancement are enabled by increasing the travel speed of welding torch from 300 to 420 mm/min. | Yueling Guo Qifei Han Jinlong Hu Xinghai Yang Pengcheng Mao Junsheng Wang Shaobo Sun Zhi He Jiping Lu Changmeng Liu | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，3： | 1 |

| 12 | A lateral super-resolution imaging method using structured illumination without phase shift显示文摘Structured illumination microscopy has been a useful method for achieving lateral super-resolution,but it typically requires at least three precise phase shifts per orientation.In this paper,we propose a super-resolution method that utilizes structured illumination without phase shift.The reconstruction process requires only a conventionally illuminated image and an image with structured illumination.This method achieves the same effect as the traditional phase shift method,and more than doubles the resolution by synthesizing a few reconstructions at different illumination frequencies.We verify the resolution improvement process using a combination of theoretical derivations and diagrams,and demonstrate its effectiveness with numerical simulations. | Yuan Jia Junsheng Lu Xinyu Chang Xiaodong Hu | 2019 | Nanotechnology and Precision Engineering2019，2，3： | 0 |
| 13 | Effect of Tempered Martensite on Magnetomechanical Damping of Ferritic Matrix Dual Phase Alloys显示文摘The influence of the volume fraction of tempered martensite on magnetomechanical damping of theferritic matrix in dual-phase alloys was studied.The experimental results showed that(1)dual-phase damping alloy is of good combination of strength and toughness: (2)good damping ca-pacity(Q-1≥5.0×10-3)can be obtained in dual-phase alloys only when the volume fraction oftempered martensite was controlled properly.The effect of martensite on magnetomechanical damp-ing of the ferritic matrix was analysed.The damping capacity of dual-phase alloys was related to thevolume fraction Vm of tempered martensite by Q<sup>-1=Q<sup>-1 (1-Vm/1+BVm)at small vibration strainamplitudes εA≤5.0×10-6. | Junsheng LU Xiaodong LIU Wenjie ZHENG Baorong WU Hui BI Central Iron and Steel Research Institute,Beijing,100081,ChinaGuijin WANG Dept.of Materials Science and Engineering,University of Pennsylvania,Philadelphia,PA 19104,USA | 1993 | Journal of Materials Science & Technology1993，9，4： | 0 |
| 14 | Muscle-inspired soft robots based on bilateral dielectric elastomer actuators显示文摘Muscle groups perform their functions in the human body via bilateral muscle actuation,which brings bionic inspiration to artificial robot design.Building soft robotic systems with artificial muscles and multiple control dimensions could be an effective means to develop highly controllable soft robots.Here,we report a bilateral actuator with a bilateral deformation function similar to that of a muscle group that can be used for soft robots.To construct this bilateral actuator,a low-cost VHB 4910 dielectric elastomer was selected as the artificial muscle,and polymer films manufactured with specific shapes served as the actuator frame.By end-to-end connecting these bilateral actuators,a gear-shaped 3D soft robot with diverse motion capabilities could be developed,benefiting from adjustable actuation combinations.Lying on the ground with all feet on the ground,a crawling soft robot with dexterous movement along multiple directions was realized.Moreover,the directional steering was instantaneous and efficient.With two feet standing on the ground,it also acted as a rolling soft robot that can achieve bidirectional rolling motion and climbing motion on a 2°slope.Finally,inspired by the orbicularis oris muscle in the mouth,a mouthlike soft robot that could bite and grab objects 5.3 times of its body weight was demonstrated.The bidirectional function of a single actuator and the various combination modes among multiple actuators together allow the soft robots to exhibit diverse functionalities and flexibility,which provides a very valuable reference for the design of highly controllable soft robots. | Yale Yang Dengfeng Li Yanhua Sun Mengge Wu Jingyou Su Ying Li Xinge Yu Lu Li Junsheng Yu | 2023 | Microsystems & Nanoengineering2023，9，5： | 0 |

| 16 | Chelation of lithium ion with crown ether for eliminating adverse effects caused by Li-TFSI/tBP doping system in Spiro-OMeTAD显示文摘Lithium bis(trifluoromethanesulfonyl)imide(Li-TFSI)/4-tert-butylpyridine(tBP)is a classic doping system for the hole transport material Spiro-OMeTAD in typical n-i-p structure perovskite solar cells(PSCs),but this system will cause many problems such as high hygroscopicity,Li+migration,pinholes and so on,which hinder PSC from maintaining high efficiency and stability for long-term.In this work,an effective strategy is demonstrated to improve the performance and stability of PSC by replacing t BP with 12-crown-4.The chelation of 12-crown-4 with Li+not only improves the doping effect of Li-TFSI,but also perfectly solves the problems caused by the Li-TFSI/tBP system.The PSC based on this strategy achieved a champion power conversion efficiency(PCE)over 21%,which is significantly better than the pristine device(19.37%).More importantly,the without encapsulated device based on Li-TFSI/12-crown-4 still maintains 87%of the initial PCE even after 60 days exposure in air,while the pristine device only maintains 22%of the initial PCE under the same aging conditions.This strategy paves a novel way for constructing efficient and stable PSCs. | Zhongquan Wan Hui Lu Jinyu Yang Yunpeng Zhang Fangyan Lin Jianxing Xia Xiaojun Yao Junsheng Luo Chunyang Jia | 2022 | Journal of Energy Chemistry2022，31，11： | 0 |
| 17 | Monte Carlo simulation based thinning and calculating method for noninvasive blood glucose sensing by near-infrared spectroscopy显示文摘Previous results show that the floating reference theory(FRT)is an effective tool to reduce the infuence of interference factors on noninvasive blood glucose sensing by near infrared spectros-copy(NIRS).It is the key to measure the floating reference point(FRP)precisely for the application of FRT.Monte Carlo(MC)simulation has been introduced to quantitatively in-vestigate the effects of positioning errors and light source drifts on measuring FRP.In this article,thinning and calculating method(TCM)is proposed to quantify the positioning error.Mean-while,the normalization process(NP)is developed to significantly reduce the error induced by light source drift.The results according to TCM show that 7 purm deviations in positioning can generate about 10.63%relative error in FRP.It is more noticeable that 1%fluctuation in light source intensity may lead to 12.21%relative errors.Gratifyingly,the proposed NP model can effectively reduce the error caused by light source drift.Therefore,the measurement system for FRPs must meet that the positioning error is less than 7 purm,and the light source drift is kept within 1%.Furthermore,an improvement for measurement system is proposed in order to take advantage of the NP model. | Congcong Ma Jia Qin Qi Zhang Junsheng Lu Kexin Xu Jingying Jiang | 2017 | Journal of Innovative Optical Health Sciences2017，，2： | 0 |
| 18 | Origami-inspired folding assembly of dielectric elastomers for programmable soft robots显示文摘Origami has become an optimal methodological choice for creating complex three-dimensional(3D)structures and soft robots.The simple and low-cost origami-inspired folding assembly provides a new method for developing 3D soft robots,which is ideal for future intelligent robotic systems.Here,we present a series of materials,structural designs,and fabrication methods for developing independent,electrically controlled origami 3D soft robots for walking and soft manipulators.The 3D soft robots are based on soft actuators,which are multilayer structures with a dielectric elastomer(DE)film as the deformation layer and a laser-cut PET film as the supporting flexible frame.The triangular and rectangular design of the soft actuators allows them to be easily assembled into crawling soft robots and pyramidal-and square-shaped 3D structures.The crawling robot exhibits very stable crawling behaviors and can carry loads while walking.Inspired by origami folding,the pyramidal and square-shaped 3D soft robots exhibit programmable out-of-plane deformations and easy switching between two-dimensional(2D)and 3D structures.The electrically controllable origami deformation allows the 3D soft robots to be used as soft manipulators for grasping and precisely locking 3D objects.This work proves that origami-inspired fold-based assembly of DE actuators is a good reference for the development of soft actuators and future intelligent multifunctional soft robots. | Yanhua Sun Dengfeng Li Mengge Wu Yale Yang Jingyou Su Tszhung Wong Kangming Xu Ying Li Lu Li Xinge Yu Junsheng Yu | 2022 | Microsystems & Nanoengineering2022，8，2： | 0 |

| 20 | High-performance flexible organic field effect transistors with print-based nanowires显示文摘Polymer nanowire(NW)organic field-effect transistors(OFETs)integrated on highly aligned large-area flexible substrates are candidate structures for the development of high-performance flexible electronics.This work presents a universal technique,coaxial focused electrohydrodynamic jet(CFEJ)printing technology,to fabricate highly aligned 90-nm-diameter polymer arrays.This method allows for the preparation of uniformly shaped and precisely positioned nanowires directly on flexible substrates without transfer,thus ensuring their electrical properties.Using indacenodithiophene-co-benzothiadiazole(IDT-BT)and poly(9,9-dioctylfluorene-co-benzothiadiazole)(F8-BT)as example materials,5 cm^(2) arrays were prepared with only minute size variations,which is extremely difficult to do using previously reported methods.According to 2D-GIXRD analysis,the molecules inside the nanowires mainly adopted face-onπ-stacking crystallite arrangements.This is quite different from the mixed arrangement of thin films.Nanowire-based OFETs exhibited a high average hole mobility of 1.1 cm^(2) V^(−1) s^(−1) and good device uniformity,indicating the applicability of CFEJ printing as a potential batch manufacturing and integration process for high-performance,scalable polymer nanowire-based OFET circuits.This technique can be used to fabricate various polymer arrays,enabling the use of organic polymer semiconductors in large-area,high-performance electronic devices and providing a new path for the fabrication of flexible displays and wearable electronics in the future. | Liangkun Lu Dazhi Wang Changchang Pu Yanyan Cao Yikang Li Pengfei Xu Xiangji Chen Chang Liu Shiwen Liang Liujia Suo Yan Cui Zhiyuan Zhao Yunlong Guo Junsheng Liang Yunqi Liu | 2023 | Microsystems & Nanoengineering2023，9，3： | 0 |
