| 1 | Mechanism of chain propagation for the synthesis of polyoxymethylene dimethyl ethers显示文摘Polyoxymethylene dimethyl ethers(PODE)were synthesized from the reaction of paraformaldehyde with dimethoxymethane(DMM)over different acid catalysts at different conditions.Products were found to follow the Schulz-Flory distribution law.The chain propagation proceeds through the insertion of an individual segment of CH2O one by one,while the simultaneous insertion of a few CH2O segments or their assembly is unlikely.Due to the restriction of this law,it is difficult to increase the selectivity to the desired products(e.g.,PODE3 4). | Yupei Zhao Zheng Xu Hui Chen Yuchuan Fu Jianyi Shen | 2013 | Journal of Energy Chemistry2013，22，6： | 36 |
| 2 | Effects of swirler position on flame response and combustion instabilities显示文摘This study is concerned with the experimental and theoretical investigation of the combustion instabilities in a premixed swirl combustor.It is focused on the effects of the swirl mixing distance on the intrinsic thermoacoustic mode.The swirler as an origin of the swirling flow is also the source of the flow disturbance,which has effects on the flame response.The location of the swirler is varied in the experiment to study the effect on combustion instabilities and flame transfer functions.A low order model is built to analyze the thermoacoustic instabilities of the combustion system.The experimental results show that the ITA switches from an unstable state to a stable state as the swirl mixing distance changes with an increment of 15 mm;while the instability of the quarter-wave mode is not varied.The measured Flame Transfer Functions(FTFs)show that the gain curves of the frequency-dependent FTFs seem to be stretched or compressed with the modulation of the swirler position,which has effects on frequencies and instabilities of thermoacoustic modes.With the low order model,the effects of flame response on combustion instabilities are analyzed and the flame dominant nature of the ITA mode is confirmed. | Liangliang XU Jianyi ZHENG Guoqing WANG Lei LI Fei QI | 2022 | Chinese Journal of Aeronautics2022，35，3： | 2 |
| 3 | Study on Plasticity Modification for Measuring High Residual Stress by Hole-Drilling Method显示文摘Hole-drilling method is a commonly used method for measuring residual stress. The calibration coefficients in ASTM E837-13 a would cause large errors due to the plasticity deformation of materials. In the study, calibration coefficients were modified in the plasticity deformation stage based on the distortion energy theory. The calibration experiment of calibration coefficients was simulated by the finite element model, and the plasticity modification formulas of 7075 aluminum alloy were obtained. From the results of uniaxial tensile loading test, the measuring errors of high residual stress are significantly reduced from-4.071%~53.440% to-5.140% ~ 0.609% after the plasticity modification. This work provides an effective way to expand the application of hole-drilling method. | ZHENG Jianyi ZHOU Chuanyan ZHENG Gaofeng LIN Junhui | 2018 | Instrumentation2018，5，4： | 1 |
| 4 | Shape-induced phase transition of vortex domain structures in ferroelectric nanodots and their controllability by electrical and mechanical loads显示文摘Shape-induced phase transition of vortex domain structures(VDSs)in BaTiO_3(BT)nanodots under open circuit boundary condition have been investigated using an effective Hamiltonian method.Our calculation indicates the tetragonal VDS missing in cubic BT nanodots can be induced by varying the shape of a nanodot from cube to platelet.Interestingly,a novel VDS is found in BT nanoplatelets in our simulations.Further investigation shows that it is a result of compromise between the ground state and the symmetry of the shape of the nanodot.Furthermore,based on the novel VDS,routes of controlling VDSs governed by homogeneous electric field and uniform stress are discussed.In particular,our results show the possibility of designing multi-states devices based on a single VDS. | Jianyi Liu Weijin Chen Yue Zheng | 2017 | Theoretical & Applied Mechanics Letters2017，7，2： | 1 |

| 9 | Controlling polar-toroidal multi-order states in twisted ferroelectric nanowires显示文摘The toroidal order of electric dipoles in ferroelectric materials has attracted attention in the past decade due to fascinating properties and great potential for enabling novel memory devices,and functional devices in general.However,facile manipulation of toroidal order in ferroelectrics remains challenging.Here,using first-principles derived simulations,we demonstrate an efficient scheme to control the polar-toroidal multi-order(PTMO)states in ferroelectric nanowires.Two feasible strategies of controlling PTMO states by a combination of homogeneous electric field and torque are carried out in ferroelectric/paraelectric composite nanowires.This is possible based on trilinear coupling between polarization,toroidization and the twist force.As a result,switching of the toroidization of the nanowire can be readily achieved by reversal of the axial polarization.The torque threshold needed to control PTMO states is also calculated and found to be relatively small,indicating the feasibility of this method.Our study demonstrates facile control of PTMO states,including ferroelectric skyrmions,in ferroelectrics and is a step towards designing ferroelectric devices based on multi-order states. | Jianyi Liu Ye Ji Shuai Yuan Lili Ding Weijin Chen Yue Zheng | 2018 | npj Computational Materials2018，，1： | 0 |
| 10 | Suggestions of management on emergency responses to epidemic outbreaks in outpatient or emergency departments of tertiary teaching hospitals显示文摘Background Patients infected with the alpha,beta,and delta strains of coronavirus disease 2019(COVID-19)usually exhibit fever,dry cough,nasal congestion,sore throat,loss of taste or smell,runny nose,conjunctivitis,fatigue,myalgia,diarrhea,and other symptoms,[1]while patients infected with the omicron strain present mild symptoms,including nasal discharge,sore throat,sneezing,headache,and cough.[2]Some patients deliberately conceal the relevant medical history,which makes it difficult to find in the pre-examination screening in outpatient or emer-gency departments.Outpatient and emergency buildings are usually linked to each other,and some older floors are poorly ventilated.Once patients with COVID-19 see a doctor in an out-patient or emergency building,especially patients infected with the omicron strain,an outbreak of the epidemic in a large area is easily possible. | Ming Wu Zhiye Fang Li Zeng Xiaohua Xie Jun Liao Lei Yang Wenping Zheng Lijie Ren Biqiang Zhou Jianyi Xiong Yong Xu Guohui Nie | 2022 | Journal of Intensive Medicine2022，2，3： | 0 |
| 11 | Bidirectional mechanical switching window in ferroelectric thin films predicted by first-principle-based simulations显示文摘Mechanical control of ferroelectric domain evolution has attracted much interest over the past decade.Nevertheless,bidirectional 180°mechanical switching,i.e.,a complete cycle of mechanical writing and then erasing of a ferroelectric nanodomain,has not yet been realized in tip-film architectures.Here,via first-principles-based molecular dynamics simulations,we demonstrate that bidirectional 180°mechanical switching is possible in tip-film architectures when screening condition of ferroelectric films and tip loading force are within an appropriate window.The switching utilizes a delicate competition between the flexoelectric field and an overlooked effective dipolar field.The effective dipolar field dominates at small tip force and trigger switching from a downward single-domain state to an upward poly-domain state,whereas the flexoelectric field dominates at relatively large tip force and enables a back-switching.Bidirectional mechanical switching is achieved by applying tip force pulses with alternatively varying strength.The dipole-dipole interaction dynamics play important roles in mechanical switching. | Jianyi Liu Weijin Chen Mengjun Wu Fei Sun Xiang Huang Yue Zheng | 2022 | npj Computational Materials2022，，1： | 0 |
| 12 | Investigation on the short-term outcome and prognostic impact of predisposition,and precipitants in inpatients with chronic liver disease from Chinese AcuTe on CHronic LIver FailurE(CATCH-LIFE)cohorts显示文摘Aim:The study aimed to investigate the short-term outcomes of hospitalized patients with chronic liver disease(CLDs)and assess the prognostic impact of predisposition and precipitants,which currently remains unclear.Methods:The study included 3970 hospitalized patients with CLDs from two prospective longitudinal multicenter studies(NCT02457637 and NCT03641872)conducted in highly endemic hepatitis B virus(HBV)areas.Competing risk analysis was used to evaluate the effect of predispositions,including the etiology and severity of CLDs and precipitants;on sequential 28,90,and 365-day liver transplantation(LT)-free mortality.Results:Among all enrolled patients,76.8%of adverse outcomes(including death and LT)within one year occurred within 90 days.Compared with alcoholic etiology,the association of HBV etiology with poorer outcomes was remarkably on the 28th day(hazard ratio[HR],1.81;95%confidence interval[CI],1.07-3.06;p=0.026);however,and dimin-ished or became insignificant at 90 days and 365 days.Cirrhosis increased the adjusted risk for 365-day(HR,1.50;CI,1.13-1.99;p=0.004)LT-free mortality when compared with noncirrhosis.In patients with cirrhosis,prior decompensation(PD)independently increased the adjusted risk of 365-day LT-free mortality by 1.25-fold(p=0.021);however,it did not increase the risk for 90-day mortality.Neither the category nor the number of precipitants influenced the adjusted risk of 28 or 90-day LT-free mortality.Conclusions:The 90-day outcome should be considered a significant endpoint for evaluating the short-term prognosis of hospitalized patients with CLD.Predisposing factors,other than etiology,mainly affected the delayed(365-day)outcome.Timely effective therapy for CLD etiology,especially antiviral treatments for HBV,and post-discharge long-term surveillance monitoring in cirrhotic patients undergoing PD are suggested to enhance disease management and reduce mortality. | Yan Zhang Wenting Tan Xiaobo Wang Xin Zheng Yan Huang Beiling Li Zhongji Meng Yanhang Gao Zhiping Qian Feng Liu Xiaobo Lu Jia Shang Yubao Zheng Weituo Zhang Shan Yin Wenyi Gu Tongyu Wang Jianyi Wei Zixuan Shen Guohong Deng Yi Zhou Yixin Hou Qun Zhang Shue Xiong Jing Liu Liyuan Long Ruochan Chen Jinjun Chen Xiuhua Jiang Sen Luo Yuanyuan Chen Chang Jiang Jinming Zhao Liujuan Ji Xue Mei Jing Li Tao Li Rongjiong Zheng Xinyi Zhou Haotang Ren Yu Shi Hai Li for the CATCH‐LIFE Study Investigators of Chinese(Acute‐on)Chronic Liver Failure(CLIF)Consortium(Ch‐CLIFC) | 2023 | Portal Hypertension & Cirrhosis2023，2，3： | 0 |

| 15 | Surface Functionalization of PEO Nanofibers Using a TiO_(2) Suspension as Sheath Fluid in a Modified Coaxial Electrospinning Process显示文摘Convenient and integration fabrication process is a key issue for the application of functional nanofibers.A surface functionalization method was developed based on coaxial electrospinning to produce ultraviolet(UV)protection nanofibers.The titanium dioxide(TiO_(2))nanoparticles suspension was delivered through the shell channel of the coaxial spinneret,by which the aggregation of TiO_(2) nanoparticles was overcome and the distribution uniformity on the surface of polyethylene oxide(PEO)nanofiber was obtained.With the content of TiO_(2) increasing from 0 to 3%(mass fraction),the average diameter of nanofibers increased from(380±30)nm to(480±100)nm.The surface functionalization can be realized during the electrospinning process to gain PEO/TiO_(2) composite nanofibers directly.The uniform distribution of TiO_(2) nanoparticles on the surface of nanofibers enhanced the UV absorption and resistance performance.The maximum UV protection factor(UPF)value of composite nanofibers reaches 2751.This work presented a novel surface-functionalized way for the preparation of composite nanofiber,which has great application potential in the field of micro/nano system integration fabrication. | ZHENG Gaofeng PENG Hao JIANG Jiaxin KANG Guoyi LIU Juan ZHENG Jianyi LIU Yifang | 2021 | Chemical Research in Chinese Universities2021，37，3： | 0 |

| 17 | Fiber-junction design for directional bending sensors显示文摘Flexible sensors in wearable electronics have become increasingly multifunctional due to the development of materials synthesis and structure design.In particular,structural design can not only add capabilities to sensors fabricated from existing available and normal materials,but also offer opportunities for the fabrication of sensors with certain desired functions.Here,we designed a series of fiber-junction structure models,in which two fibers were simply hooked to each other to form a junction on a flexible printed circuit,for fabrication of directional bending sensors.The value and direction of bending angle are related to the change in electronic signal by a theoretical expression,allowing us to employ a simple and practicable method to use available conductive fiber materials to fabricate high-sensitivity,high-resolution and directional bending sensors.In addition,these models are generally applicable,which have broad combination with different conductive fiber,and corresponding bending sensors all possess capability of directional identification.Furthermore,the capability of identifying directional bending was demonstrated by human motion monitoring such as joint bending and muscle contraction. | Zhundong Li Fengming Hu Zhiming Chen Jingcheng Huang Guoning Chen Runbo Chen Minmin Wei Kete Lao Jiajia Hu Jintao Zheng Lvfei Wang Yuan Yao Xiaoyan Hu Baowen Liang Min Yang Xihong Lu Jinxiu Wen Jianyi Luo | 2021 | npj Flexible Electronics2021，5，1： | 0 |
