| 1 | AN UNFITTED hp-INTERFACE PENALTY FINITE ELEMENT METHOD FOR ELLIPTIC INTERFACE PROBLEMS显示文摘An hp version of interface penalty finite element method(hp-IPFEM)is proposed to solve the elliptic interface problems in two and three dimensions on unfitted meshes.Error estimates in broken H1 norm,which are optimal with respect to h and suboptimal with respect to p by half an order of p,are derived.Both symmetric and non-symmetric IPFEM are considered.Error estimates in L^2 norm are proved by the duality argument.All the estimates are independent of the location of the interface relative to the meshes.Numerical examples are provided to illustrate the performance of the method.This paper is adapted from the work originally post on arXiv.com by the same authors(arXiv:1007.2893v1). | Haijun Wu Yuanming Xiao | 2019 | Journal of Computational Mathematics2019，37，3： | 3 |
| 2 | Intercalating Ultrathin MoO_3 Nanobelts into MXene Film with Ultrahigh Volumetric Capacitance and Excellent Deformation for High-Energy-Density Devices显示文摘The restacking hindrance of MXene films restricts their development for high volumetric energy density of flexible supercapacitors toward applications in miniature,portable,wearable or implantable electronic devices.A valid solution is construction of rational heterojunction to achieve a synergistic property enhancement.The introduction of spacers such as graphene,CNTs,cellulose and the like demonstrates limited enhancement in rate capability.The combination of currently reported pseudocapacitive materials and MXene tends to express the potential capacitance of pseudocapacitive materials rather than MXene,leading to low volumetric capacitance.Therefore,it is necessary to exploit more ideal candidate materials to couple with MXene for fully expressing both potentials.Herein,for the first time,high electrochemically active materials of ultrathin MoO3 nanobelts are intercalated into MXene films.In the composites,MoO3 nanobelts not only act as pillaring components to prevent restacking of MXene nanosheets for fully expressing the MXene pseudocapacitance in acidic environment but also provide considerable pseudocapacitive contribution.As a result,the optimal M/MoO3 electrode not only achieves a breakthrough in volumetric capacitance(1817 F cm-3 and 545 F g-1),but also maintains good rate capability and excellent flexibility.Moreover,the corresponding symmetric supercapacitor likewise shows a remarkable energy density of 44.6 Wh L-1(13.4 Wh kg-1),rendering the flexible electrode a promising candidate for application in high-energy-density energy storage devices. | Yuanming Wang Xue Wang Xiaolong Li Rong Liu Yang Bai Huanhao Xiao Yang Liu Guohui Yuan | 2020 | Nano-Micro Letters2020，12，9： | 2 |

| 6 | An hp Adaptive Uniaxial Perfectly Matched Layer Method for Helmholtz Scattering Problems显示文摘We propose an adaptive strategy for solving high frequency Helmholtz scattering problems.The method is based on the uniaxial PML method to truncate the scattering problem which is defined in the unbounded domain into the bounded domain.The parameters in the uniaxial PML method are determined by sharp a posteriori error estimates developed by Chen and Wu[8].An hp-adaptive finite element strategy is proposed to solve the uniaxial PML equation.Numerical experiments are included which indicate the desirable exponential decay property of the error. | Zhiming Chen Benqi Guo Yuanming Xiao | 2009 | Communications in Computational Physics2009，5，2： | 1 |
| 7 | An unusual superhydrophilic/superoleophobic sponge for oil-water separation显示文摘Development of porous materials with anti-fouling and remote controllability is highly desired for oil-water separation application yet still challenging. Herein, to address this challenge, a sponge with unusual superhydrophilicity/superoleophobicity and magnetic property was fabricated through a dip-coating process. To exploit its superhydrophilic/superoleophobic property, the obtained sponge was used as a reusable water sorbent scaffold to collect water from bulk oils without absorbing any oil. Owing to its magnetic property, the sponge was manipulated remotely by a magnet without touching it directly during the whole water collection process, which could potentially lower the cost of the water collection process. Apart from acting as a water-absorbing material, the sponge can also be used as affiliation material to separate water from oil-water mixture and oil in water emulsion selectively, when fixed into a cone funnel. This research provides a key addition to the field of oil-water separation materials. | Jingwei Lu Xiaotao Zhu Xiao Miao Bo Wang Yuanming Song Guina Ren Xiangming Li | 2020 | Frontiers of Materials Science2020，14，3： | 1 |
| 8 | Grooved Fibers:Preparation Principles Through Electrospinning and Potential Applications显示文摘The surface morphology of micro-and nano-scale fber determines its application to a great extent.At present,a variety of secondary morphology of microfbers and nanofbers,such as porous,wrinkle,groove and so on,have been prepared.Among them,grooved micro-and nano-fbers are attracting more and more attention because of their unique morphology and properties.In this paper,we review the literature on grooved fbers due to void-based elongation,wrinkle-based elongation,collapsed jet-based elongation and selective dissolution.By contrast,the method of phase separation is simpler and more commonly used than selective dissolution.What is more interesting is that the number and depth of grooves on the fber surface can be well controlled by adjusting the experimental parameters,which greatly increases the research value and application felds of grooves micro-nano fbers.Grooved fbers can be made from a range of materials:polycaprolactone(PCL),polylactic acid(PLA),polystyrene(PS),cellulose acetate butyrate(CAB)and other polymers.The applications of grooved micro-nano fbers are discussed in detail,including peripheral nerve regeneration,water manipulation and energy conversion. | Lei Zhan Jixia Deng Qinfei Ke Xiao Li Yuanming Ouyang Chen Huang Xuqing Liu Yun Qian | 2022 | Advanced Fiber Materials2022，4，2： | 1 |
| 9 | A slippery hydrogel coating with durable oil-repellent property and self-regeneration capacity显示文摘Traditional lubricant impregnated surfaces usually required fluorinated lubricants to achieve slippery oil repellency, but the lubricants infused were expensive and toxic and also suffered from limited stability because of their migrating, evaporating, and leaking during use. Herein, to address this issue, we fabricated a durably fluorine-free slippery oil-repellent hydrogel coating using water as the lubricant. Due to its enhanced water-binding affinity, water could wet the hydrogel completely and form a hydrated-water layer on the surface. The hydrated water layer could act as a lubricant to repel foreign oils, which allowed the hydrogel to display slippery oil-repellency in air, exhibit superoleophobicity underwater, and resist oil fouling upon oil immersion.The hydrogel kept its oil-repellent properties after mechanical tests as well as thermal and freezing treatments,demonstrating its durability. Thanks to its moisture absorption, the water lubricant layer could self-regenerate upon the lubricated water layer depletion through exposure to a humid environment. Exploiting it is water-attracting and oil repellency, the hydrogel coating was demonstrated as a versatile platform for oil/water separation, polymer/water separation, drag-reduction, and antifogging. | XU Ting GAO ZhongShuai LI FangChao MIAO Gan JIA YuYu MIAO Xiao ZHU XiaoTao LU JingWei WANG Bo SONG YuanMing REN GuiNa LI XiangMing | 2022 | Science China(Technological Sciences)2022，65，8： | 0 |
| 10 | Concentrated hydrogel electrolyte for integrated supercapacitor with high capacitance at subzero temperature显示文摘Hydrogel electrolytes with anti-freezing properties are crucial for flexible quasi-solid-state supercapacitors operating at low temperatures.However,the electrolyte freezing and sluggish ion migration caused by the cold temperature inevitably damage the flexibility and electrochemical properties of supercapacitors.Herein,we introduce the concentrated electrolyte into a freezecasted poly(vinyl alcohol)hydrogel film not only reducing the freezing point of the electrolyte(−51.14℃)in gels for ensuring the flexibility,but also improving the ionic conductivity of the hydrogel electrolyte(5.92 mS cm^(−1)at−40℃)at low temperatures.As a proof,an all-in-one supercapacitor,synthesized by the one-step polymerization method,exhibits a good specific capacitance of 278.6 mF cm^(−2)at−40℃(accounting for 93.8%of the capacitance at room temperature),high rate performance(50%retention under the 100-fold increase in current densities),and long cycle life(88.9%retention after 8,000 cycles at−40℃),representing an excellent low-temperature performance.Our results provide a fresh insight into the hydrogel electrolyte design for flexible energy storage devices operating in the wide range of temperature and open up an exciting direction for improving all-in-one supercapacitors. | Yang Bai Rong Liu Yang Liu Yuanming Wang Xue Wang Huanhao Xiao Guohui Yuan | 2021 | Science China Chemistry2021，64，5： | 0 |

| 12 | 2-4 First Isochronous Mass Measurement in Neutron-rich Region at CSRe显示文摘Mass is one of the fundamental properties of atomic nuclei. Isochronous mass spectrometry (IMS), using astorage ring combined with an in-flight separator, has been shown to be a powerful tool for mass measurementof exotic nuclei[1]. Recently, masses of many proton-rich nuclides were accurately determined at the HIRFL-CSRfacility[2]. In this paper, we described the first isochronous mass measurement of neutron-rich nuclides at CSRe.This experiment was performed at the end of 2011. In the experiment, the primary beam of 86Kr28+ ions wasaccumulated and accelerated to an energy of 460.65 MeV/u in the synchrotron CSRm. The 86Kr28+ ions were fastextracted and focused on a 15 mm thick beryllium target which was placed at the entrance of the RIBLL2 (anin-flight fragment separator). | Xu Xing Wang Meng Zhang Yuhu Xu Hushan Tu Xiaolin Yu.A.Litvinov Zhou Xiaohong Sun Baohua Yuan Youjin Xia Jiawen Yang Jiancheng K.Blaum Chen Ruijiu Chen Xiangchen Fu Chaoyi Ge Zhuang Hu Zhengguo Huang Wenjia Liu Dawei Y.H.Lam Ma Xinwen Mao Ruishi T.Uesaka Xiao Guoqing Xing Yuanming T.Yamaguchi Y.Yamaguchi Zeng Qi Yan Xinliang Zhao Hongwei Zhao Tiecheng Zhang Wei Zhan Wenlong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 13 | 2-6 First Isochronous Mass Measurements with Two Time-of-Flight Detectors at CSRe显示文摘In conventional isochronous mass spectrometry (IMS), single time-of-flight (TOF) method is adopted to measurethe ions' revolution times in a storage ring which can then be used to calculate the ions' masses. However, themass-to-charge ratio (m=q) is only related to the revolution time (T) under the condition that is equal to taccording to the following equation: | Xing Yuanming Zhang Yuhu Wang Meng Xu Hushan Shuai Peng Xu Xing Chen Ruijiu Yan Xinliang Tu Xiaolin Zhang Wei Fu Chaoyi Zeng Qi Yu.A.Litvinov K.Blaum Chen Xiangcheng Ge Zhuang Gao Bingshui Huang Wenjia S.A.Litvinov Liu Dawei Ma Xinwen Mao Ruishi Xiao Guoqing Yang Jiancheng Yuan Youjin Zhou Xiaohong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 14 | 2-9 Half-life Measurement of 94mRu44+ at CSRe显示文摘A radioactive nucleus is characterized with an intrinsic half-life. However, for a nuclear species, the half-lives inneutral atoms could be very different from that in highly charged ions. The half-lives of some highly charged ionshave been directly measured at GSI for multiple motivations[1]. In the same case, the nuclear state(i:e the isomer)may be in the range of several tens of microseconds and their half-live can be measured using isochronous massspectrometry. The J = 8+ isomeric state in 94Ru was chosen to test this method. The half-life of this isomer is71 s [2] in neutral atoms, and the excitation energy is 2.64 MeV. The internal conversion coefficient of this decayin neutral atom is 0.335. So its half-life in the bare nucleus would be modified to be 94.78 s when the internalconversion channel is blocked. | Zeng Qi Zhang Yuhu Wang Meng Xu Hushan Tu Xiaolin Zhou Xiaohong Yan Xinliang Chen Ruijiu Huang Wenjia Ge Zhuang Liu Dawei Fu Chaoyi Sun Mingze Mei Bo Xu Xing Xing Yuanming Shuai Peng Zang Yongdong Zhang Wei Xiao Guoqing Yu.A.Litvinov Isao.Tanihata | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |

| 16 | Cell metabolism pathways involved in the pathophysiological changes of diabetic peripheral neuropathy显示文摘Diabetic peripheral neuropathy is a common complication of diabetes mellitus.Elucidating the pathophysiological metabolic mechanism impels the generation of ideal therapies.However,existing limited treatments for diabetic peripheral neuropathy expose the urgent need for cell metabolism research.Given the lack of comprehensive understanding of energy metabolism changes and related signaling pathways in diabetic peripheral neuropathy,it is essential to explore energy changes and metabolic changes in diabetic peripheral neuropathy to develop suitable treatment methods.This review summarizes the pathophysiological mechanism of diabetic peripheral neuropathy from the perspective of cellular metabolism and the specific interventions for different metabolic pathways to develop effective treatment methods.Various metabolic mechanisms(e.g.,polyol,hexosamine,protein kinase C pathway)are associated with diabetic peripheral neuropathy,and researchers are looking for more effective treatments through these pathways. | Yaowei Lv Xiangyun Yao Xiao Li Yuanming Ouyang Cunyi Fan Yun Qian | 2024 | Neural Regeneration Research2024，19，3： | 0 |
| 17 | 2-5 Mass Measurements of Neutron-defcient Nuclides 79Y,81,82Zr,83,84Nb显示文摘The masses of neutron-defcient nuclides play a critical role in the calculation of astrophysical rapid proton-capture processes[1].Neutron-defcient nuclides with mass number∧around 80 are the last set of nuclides with unknown masses on the pathway of vp-process[2].The mass measurement of nuclides would be very useful.In 2016,masses of neutron-defcient nuclides 79Y,81Zr,82Zr,83Nb and 84Nb nuclei were precisely measured directly by the experimental storage-ring CSRe at Lanzhou. | Xing Yuanming Zhang Yuhu Wang Meng Xu Hushan Chen Ruijiu Shuai Peng Yan Xinliang Fu Chaoyi Xu Xing Tu Xiaolin Zhang Wei Zeng Qi Yu.A.Litvinov K.Blaum Chen Xiangcheng Ge Zhuang Gao Bingshui Huang Wenjia S.A.Litvinov Ma Xinwen Mao Ruishi Xiao Guoqing Yang Jiancheng Yuan Youjin Zhou Xiaohong | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 18 | 2-6 Mass Prediction of Neutron-defcient N=Z Nuclides 78Y,80Zr,82Nb and 84Mo显示文摘We have reported the mass measurements of neutron-deficient nuclides 79Y,81;82Zr,83;84Nb in this year’s Annual Report.However,for the N=Z nuclides close to A=80,the yield is much lower and even if they can be produced,there is still great difficult to identify them because of their quite similar mass-to-charge ratio and revolution times.However,their mass are extremely important for rapid proton capture process,for example,80Zr and 84Mo are waiting points of rp-process.Their masses can greatly effect the reaction flow of proton capture on them and then the abundance of the heavier nuclides.In addition,the separation energy of 84Mo(determined by the mass of 80Zr and 84Mo)has a strong impact on the 83Nb(p,α)reaction rate and plays a key role in the formation of Zr-Nb Fig. | Xing Yuanming Zhang Yuhu Wang Meng Xu Hushan Chen Ruijiu Chen Xiangcheng Fu Chaoyi Ge Zhuang Gao Bingshui Huang Wenjia Ma Xinwen Mao Ruishi S.A.Litvinov Shuai Peng Tu Xiaolin Xiao Guoqing Xu Xing Yan Xinliang Yu.A.Litvinov Yang Jiancheng Yuan Youjin Zhang Wei Zeng Qi Zhou Xiaohong | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 19 | 2-7 Study of Zr-Nb Cycle in Astrophysical rp-process显示文摘At a certain high temperature,this cycle will be dominant and end the rp-process to heavier region[2].It provides an upper temperature limit for rp-process along the proton drip line to produce nuclides beyond A=84,including the light p nuclides of 92;94Mo,96;94Ru.The existence of Zr-Nb cycle is an important question in rp-process[2].α-separation energy(Sα)of 84Mo plays an important role in the formation of this cycle.A strong enhancement of 83Nb(p,α)reaction rate is due to a very low Sαof 84Mo[1]. | Xing Yuanming Zhang Yuhu Wang Meng Li Kuoang Tang Xiaodong Xu Hushan Chen Ruijiu Chen Xiangcheng Fu Chaoyi Ge Zhuang Gao Bingshui Huang Wenjia Ma Xinwen Mao Ruishi S.A.Litvinov Shuai Peng Tu Xiaolin Xiao Guoqing Xu Xing Yan Xinliang Yu.A.Litvinov Yang Jiancheng Yuan Youjin Zhang Wei Zeng Qi Zhou Xiaohong | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 20 | Non-electric bioelectrical analog strategy by a biophysical-driven nano-micro spatial anisotropic scaffold for regulating stem cell niche and tissue regeneration in a neuronal therapy显示文摘The slow regenerating rate and misdirected axonal growth are primary concerns that disturb the curative outcome of peripheral nerve repair.Biophysical intervention through nerve scaffolds can provide efficient,tunable and sustainable guidance for nerve regrowth.Herein,we fabricate the reduced graphene oxide(rGO)/polycaprolactone(PCL)scaffold characterized with anisotropic microfibers and oriented nanogrooves by electrospinning technique.Adipose-derived stem cells(ADSCs)are seeded on the scaffolds in vitro and the viability,neural differentiation efficiency and neurotrophic potential are investigated.RGO/PCL conduits reprogram the phenotype of seeded cells and efficiently repair 15 mm sciatic nerve defect in rats.In summary,biophysical cues on nerve scaffolds are key determinants to stem cell phenotype,and ADSC-seeded rGO/PCL oriented scaffolds are promising,controllable and sustainable approaches to enable peripheral nerve regeneration. | Xiangyun Yao Lei Zhan Zhiwen Yan Juehong Li Lingchi Kong Xu Wang Huimin Xiao Huiquan Jiang Chen Huang Yuanming Ouyang Yun Qian Cunyi Fan | 2023 | Bioactive Materials2023，，2： | 0 |
