| 1 | Insight into tribological problems of green ship and corresponding research progresses显示文摘The so-called 'green ship' is being regarded as a potential solution to the problems that the shipping industry faces, such as energy conservation and environmental protection. Some new features, such as integrated renewable energy application, biomimetic materials, and antifriction and wear resistant coating have been accepted as the typical characteristics of a green ship, but the tribology problems involved in these domains have not been precisely redefined yet. Further, the related research work is generally focused on the technology or material itself, but not on the integration of the applicable object or green ship, marine environment, and tribological systematical analysis from the viewpoint of the energy efficiency design index(EEDI) and ship energy efficiency management plan(SEEMP) improvements. Aiming at the tribology problems of the green ship, this paper reviews the research status of this issue from three specific domains, which are the tribology problems of the renewable energy system, tribological research for hull resistance reduction, and energy efficiency enhancement. Some typical tribological problems in the sail-auxiliary system are discussed, along with the solar photovoltaic system and hull drag reduction in traditional marine mechanical equipment. Correspondingly, four domains that should be further considered for the future development target of the green ship are prospected. | Yuwei SUN Xinping YAN Chengqing YUAN Xiuqin BAI | 2018 | Friction2018，6，4： | 12 |

| 5 | Improvements of heat resistance and adhesive property of condensed poly-nuclear aromatic resin via epoxy resin modification显示文摘A bisphenol epoxy resin was used as modifier to increase the heat resistance of condensed poly-nuclear aromatic(COPNA) resin. The basic properties of COPNA resin and modified resin were characterized by Fourier transform infrared spectroscopy(FT-IR), nuclear magnetic resonance spectroscopy(1H-NMR), vapor pressure osmometry(VPO) and elemental analysis(EA). Average structural parameters of resins were calculated by the improved Brown-Ladner method, and heat resistance of resins was tested by thermogravimetric analysis(TGA). The chemical structure, mechanical properties and heat resistivity of the resin/graphite composites prepared with different resins were compared. The results show that the adhesive property and heat resistance of COPNA resin can be remarkably improved by addition of 5 wt.% epoxy resin. The reason is that the reactions between epoxy groups of epoxy resin and hydroxyl groups of COPNA resin improve the heat resistance and adhesive property of COPNA resin. Electric motor brushes with good mechanical properties and low electrical resistivity were successfully prepared by using the modified resin as binder. | Wu Mingbo Wang Yuwei Jiang Wei Li Shibin Sun Qiqian Zheng Jingtang Qiu Jieshan | 2014 | Petroleum Science2014，11，4： | 5 |
| 6 | Structural Insights into the CatalyticMechanism of a Plant Diterpene Glycosyltransferase SrUGT76G1显示文摘Diterpene glycosyltransferase UGT76G1 from Stevia rebaudiana (SrUGT76G1) is key to the generation ofeconomically important steviol glycosides (SGs), a group of natural sweeteners with high-intensity sweetness. SrUGT76G1 accommodates a wide range of steviol-derived substrates and many other small molecules. We report here the crystal structures of SrUGT76G1 in complex with multiple ligands to answer howthis enzyme recognizes diterpenoid aglycones and catalyzes the 1,3-sugar chain branching. A spaciouspocket for sugar-acceptor binding was observed from the determined SrUGT76G1 structures, which canexplain its broad substrate spectrum. Residues Gly87 and Leu204 lining the pocket play key roles in switching between diterpenoid and flavonoid glucosylation. An engineered mutant of SrUGT76G1, T284S, couldcatalyze a selectively increased production of next-generation sweetener rebaudioside M, with diminishedside product of rebaudioside I. Taken together, these resutls provide significant insights into molecularbasis of the substrate specificity of scarcely documented diterpenoid glycosyltransferases and wouldfacilitate the structure-guided glycoengineering to produce diversified diterpenoids with new activities. | Zhifeng Liu Jianxu Li Yuwei Sun Peng Zhang Yong Wang | 2020 | Plant Communications2020，1，1： | 3 |
| 7 | Bosonic quantum error correction codes in superconducting quantum circuits显示文摘Quantum information is vulnerable to environmental noise and experimental imperfections,hindering the reli-ability of practical quantum information processors.Therefore,quantum error correction(QEC)that can pro-tect quantum information against noise is vital for universal and scalable quantum computation.Among many different experimental platforms,superconducting quantum circuits and bosonic encodings in superconducting microwave modes are appealing for their unprecedented potential in QEC.During the last few years,bosonic QEC is demonstrated to reach the break-even point,i.e.the lifetime of a logical qubit is enhanced to exceed that of any individual components composing the experimental system.Beyond that,universal gate sets and fault-tolerant operations on the bosonic codes are also realized,pushing quantum information processing towards the QEC era.In this article,we review the recent progress of the bosonic codes,including the Gottesman-Kitaev-Preskill codes,cat codes,and binomial codes,and discuss the opportunities of bosonic codes in various quantum applications,ranging from fault-tolerant quantum computation to quantum metrology.We also summarize the challenges associated with the bosonic codes and provide an outlook for the potential research directions in the long terms. | Weizhou Cai Yuwei Ma Weiting Wang Chang-Ling Zou Luyan Sun | 2021 | Fundamental Research2021，1，1： | 3 |
| 8 | Structural Assessment of Printed Circuit Heat Exchangers in Supercritical CO_(2) Waste Heat Recovery Systems for Ship Applications显示文摘Printed circuit heat exchangers(PCHEs)are considered as the most promising heat exchangers for use of the supercritical carbon dioxide(S-CO_(2))Brayton cycle.As crucial components operating at high pressure and thermal load at the same time,PCHE structural integrity evaluations are essential.In this study,to assess the structural strength of PCHEs serving as recuperators and precoolers in the S-CO_(2) Brayton cycle as a waste heat recovery system for marine engines,the finite element method(FEM)is used and compared with a currently used method from ASME codes.The effects of temperature and pressure on the hot and cold sides are studied in terms of the temperature and pressure differences between the two sides and the main factors affecting its strength discussed.Then,detailed stress intensities of a PCHE under design conditions are investigated,and the results indicate that the highest stress appears at the middle of the semicircular arc of the channel,except for a concentration near the channel tip regions.Stresses of the PCHE are mainly caused by both pressure and temperature differences,with the minimum effect from temperature.The synthesis of the temperature and pressure fields exhibits a complicated action on the total stress under the design conditions.FEM was a more comprehensive means for structural assessment than the method from ASME codes.Further structural optimization of PCHE is conducted to ensure a maximum life span.This research work can provide theoretical guidance for structural integrity assessment of PCHE for the S-CO_(2) Brayton cycle. | WANG Jian YAN Xinping LU Mingjian SUN Yuwei WANG Jiawei | 2022 | Journal of Thermal Science2022，31，3： | 2 |
| 9 | Experimental repetitive quantum channel simulation显示文摘Universal control of quantum systems is a major goal to be achieved for quantum information processing,which demands thorough understanding of fundamental quantum mechanics and promises applications of quantum technologies. So far, most studies concentrate on ideally isolated quantum systems governed by unitary evolutions, while practical quantum systems are open and described by quantum channels due to their inevitable coupling to environment. Here, we experimentally simulate arbitrary quantum channels for an open quantum system, i.e. a single photonic qubit in a superconducting quantum circuit.The arbitrary channel simulation is achieved with minimum resource of only one ancilla qubit and measurement-based adaptive control. By repetitively implementing the quantum channel simulation,we realize an arbitrary Liouvillian for a continuous evolution of an open quantum system for the first time. Our experiment provides not only a testbed for understanding quantum noise and decoherence,but also a powerful tool for full control of practical open quantum systems. | Ling Hu Xianghao Mu Weizhou Cai Yuwei Ma Yuan Xu Haiyan Wang Yipu Song Chang-Ling Zou Luyan Sun | 2018 | Science Bulletin2018，63，23： | 2 |
| 10 | Modulation of Beta Oscillations for Implicit Motor Timing in Primate Sensorimotor Cortex during Movement Preparation显示文摘Motor timing is an important part of sensorimotor control. Previous studies have shown that beta oscillations embody the process of temporal perception in explicit timing tasks. In contrast, studies focusing on beta oscillations in implicit timing tasks are lacking. In this study, we set up an implicit motor timing task and found a modulation pattern of beta oscillations with temporal perception during movement preparation. We trained two macaques in a repetitive visually-guided reach-to-grasp task with different holding intervals. Spikes and local field potentials were recorded from microelectrode arrays in the primary motor cortex, primary somatosensory cortex, and posterior parietal cortex. We analyzed the association between beta oscillations and temporal interval in fixedduration experiments(500 ms as the Short Group and1500 ms as the Long Group) and random-duration experiments(500 ms to 1500 ms). The results showed that the peak beta frequencies in both experiments ranged from15 Hz to 25 Hz. The beta power was higher during the hold period than the movement(reach and grasp) period.Further, in the fixed-duration experiments, the mean poweras well as the maximum rate of change of beta power in the first 300 ms were higher in the Short Group than in the Long Group when aligned with the Center Hit event. In contrast, in the random-duration experiments, the corresponding values showed no statistical differences among groups. The peak latency of beta power was shorter in the Short Group than in the Long Group in the fixed-duration experiments, while no consistent modulation pattern was found in the random-duration experiments. These results indicate that beta oscillations can modulate with temporal interval in their power mode. The synchronization period of beta power could reflect the cognitive set maintaining working memory of the temporal structure and attention. | Hongji Sun Xuan Ma Liya Tang Jiuqi Han Yuwei Zhao Xuejiao Xu Lubin Wang Peng Zhang Luyao Chen Jin Zhou Changyong Wang | 2019 | Neuroscience Bulletin2019，35，5： | 2 |
| 11 | Rapidly developable therapeutic-grade equine immunoglobulin against the SARS-CoV-2 infection in rhesus macaques显示文摘Dear Editor,The unprecedented COVID-19 pandemic caused by SARS-CoV-2 remains ongoing,but there is a lack of fully effective treatments.Convalescent plasma-derived hyperimmune globulins have been a safe and effective treatment but restricted by the difficulties in obtaining sufficient plasma with high antibody titers from a large number of recovered patients.Heterologous antibodies,particularly equine antibodies,have been widely used for decades as the therapeutics against some viral infections or as antivenoms.1 Equine antibodies could be rapidly developed and manufactured into therapeutic antibodies in large quantities under WHO standardized guidelines.Here we explored the development of equine antibody-derived F(ab′)2 as an option to treat COVID-19 by targeting the receptor-binding domain(RBD)of the viral spike protein that is essential for the viral entry into the host cells.2 We observed excellent neutralization titers of the F(ab′)2 in vitro and high potency against SARS-CoV-2 infection in the nonhuman primate rhesus macaques. | Xiaolei Liu Yi Liu Xuemin Jin Zhanlong He Zhen Huang Shumin Sun Yuwei Gao Jingyu Li Qin Ning Zhongping Xie Ningyi Jin Mingyuan Liu | 2022 | Signal Transduction and Targeted Therapy2022，7，8： | 2 |
| 12 | Chronic electrical stimulation induces functional network changes in cortical neuron cultures显示文摘Recent studies demonstrated that a functional brain network could be regarded as a complex network.With the help of network theory,neuroscientists can identify common organizational principles of the functional brain networks.As a consequence,some non-random organizational features,such as'small world'(most of the nodes are not connected directly but can communicate with few intermediate relay steps)and'rich club'(nodes that are rich in connections tend to form strongly interconnected clubs),have been found in functional brain network.Recently,the'small world'organizational feature of neuronal functional networks in vitro was found to be influenced by external applications.However,little is known about the influence of chronic electrical stimulation on functional networks of dissociated cortical cultures during network development.In the present study,cortical cultures were electrically stimulated at a frequency of 0,0.02,and 0.2 Hz,between 7 and 26 days in vitro(DIV).The spontaneous activity of the cortical cultures was recorded using MEAs.Next,a cross-covariance method and graph theory were applied to investigate organizational feature of functional networks.Our results showed that over 3 weeks of stimulation,the network density significantly increased with maturation in the control and 0.02 Hz stimulation groups,but not in 0.2 Hz stimulation groups.Moreover,all the cultures had a small-world topology at 14,18,22,and 26 DIV,free from the effect of chronic electrical stimulation.Besides,we found an asymmetry effect that partial electrical stimulation inhibited the formation of node connections in stimulated areas.This effect was more pronounced at 0.2 Hz than at 0.02 Hz stimulation.Our results suggest that electrical stimulation does not affect the small-world properties of neural cultures.Instead,electrical stimulation modulates connectivity patterns,and neurons within the stimulated area are less connected than neurons outside the stimulated area. | WU SongFang WANG LuBin ZHAO YuWei SUN HongJi LANG YiRan WANG ChangYong HAN JiuQi WANG Yan HAN Yao | 2020 | Science China(Technological Sciences)2020，63，4： | 2 |
| 13 | integrated structure for recognition of different joint motion states with the assistance of a deep learning algorithm显示文摘Accurate motion feature extraction and recognition provide critical information for many scientific problems.Herein,a new paradigm for a wearable seamless multimode sensor with the ability to decouple pressure and strain stimuli and recognize the different joint motion states is reported.This wearable sensor is integrated into a unique seamless structure consisting of two main parts(a resistive component and a capacitive component)to decouple the different stimuli by an independent resistance-capacitance sensing mechanism.The sensor exhibits both high strain sensitivity(GF=7.62,0-140%strain)under the resistance mechanism and high linear pressure sensitivity(S=3.4 kPa^(-1),0-14 kPa)under the capacitive mechanism.The sensor can differentiate the motion characteristics of the positions and states of different joints with precise recognition(97.13%)with the assistance of machine learning algorithms.The unique integrated seamless structure is achieved by developing a layer-bylayer casting process that is suitable for large-scale manufacturing.The proposed wearable seamless multimode sensor and the convenient process are expected to contribute significantly to developing essential components in various emerging research fields,including soft robotics,electronic skin,health care,and innovative sports systems applications. | Lei Wen Meng Nie Pengfan Chen Yu-na Zhao Jingcheng Shen Chongqing Wang Yuwei Xiong Kuibo Yin Litao Sun | 2022 | Microsystems & Nanoengineering2022，8，1： | 1 |
| 14 | Research on oil film characteristics of piston pair in swash plate axial piston pump显示文摘The research on the oil film characteristic of piston pair is beneficial to the design and optimization of friction pair,which can improve the performance of piston pump.The fluid pressure of piston cavity is accurately obtained by AMEsim simulation.Oil film thickness field model of piston pair under the slanting state of piston is established,and the distribution law is numerically analyzed under different speed and pressure by Matlab.The experiment model pump for oil film characteristic of piston pair is designed to measure oil film thickness under the pressure of 18 MPa.The experiment results show that oil film thickness varies greatly under high pressure,and oil film thickness fluctuates sharply under low speed.The minimum oil film thickness increases with spindle speed increasing and oil film characteristic of piston pair based on the numerical analysis method is verified.This method lays a foundation for studying the friction performance of piston pair in the axial piston pump. | 王晓晶 Sun Yuwei Shen Zhiqi | 2020 | High Technology Letters2020，26，3： | 1 |
| 15 | Chlorophyll-based organic solar cells with improved power conversion efficiency显示文摘Chlorophylls(Chls), and associated chlorophyll derivatives, are one of the oldest, most versatile organic semiconductors found in nature. Herein, we present two easily semi-synthesized chlorophyll derivatives, namely, chlorin e6 trimethyl ester(Ce6Me3) and its copper complex(Cu–Ce6 Me3), as the p-type dopants for organic semiconductors and their impact in organic solar cells(OSCs). In our study, both Chls showed intense Soret and Q y bands in the UV-visible spectra, leading to an effect means for capturing solar light and energy. Chls also exhibited high carrier mobility owing to the partial formation of aggregates through the spin-coating process. Using Chls, we fabricated OSCs in both planar-heterojunction(PHJ) and bulkheterojunction(BHJ) solar cell configurations, together with C70/PC70 BM as electron acceptors. In PHJ solar cells, we received solar power conversion efficiencies(PCEs) of only 0.85% and 0.93% for Cu–Ce6 Me 3-and Ce6Me3-based devices, respectively, with the thickness of the donor layer at 5 nm. In BHJ cells, we achieved much higher PCEs of 1.53% and 2.05% for Cu–Ce6Me3 :PC 70 BM and Ce6Me3 :PC 70 BM respectively, where both blending ratios were set to 1:8. The improvement on PCE in BHJ cells may be attributed to the better charge separation increase at the donor–acceptor interface. | Shenghan Wang Shengnan Duan Yuwei Wang Chenglin Sun Xiao-Feng Wang Shin-ichi Sasaki | 2019 | Journal of Energy Chemistry2019，28，11： | 1 |

| 17 | Curing Mechanism of Condensed Polynuclear Aromatic Resin and Thermal Stability of Cured Resin显示文摘In order to improve the thermal stability of condensed polynuclear aromatic(COPNA) resin synthesized from vacuum residue, 1,4-benzenedimethanol was added to cure COPNA resin. The curing mechanism was investigated by proton nuclear magnetic resonance spectrometry, solid carbon-13 nuclear magnetic resonance spectrometry and Fourier transform infrared spectroscopy. Microstructures of the uncured and the cured COPNA resins were studied by scanning electron microscopy and X-ray diffractometry. The thermal stability of COPNA resins before and after curing was tested by thermogravimetric analysis. The element composition of the cured COPNA resin heated at different temperatures was analyzed by an element analyzer. The results showed that the uncured COPNA resin reacted with the cross-linking agent during the curing process, and the curing mechanism was confirmed to be the electrophilic substitution reaction. Compared with the uncured COPNA resin, the cured COPNA resin had a smooth surface, well-ordered and streamlined sheet structure with more crystalline solids, better molecular arrangement and orientation. The weight loss process of the uncured and cured COPNA resins was divided into three stages. Carbon residue of the cured COPNA resin was 41.65% at 600 ℃, which was much higher than 25.02% of the uncured COPNA resin, which indicated that the cured COPNA resin had higher thermal stability. | Li Shibin Sun Qiqian Wang Yuwei Wu Mingbo Zhang Zailong | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，2： | 1 |

| 20 | Development and transdifferentiation into inner hair cells require Tbx2显示文摘Atohl is essential for the development of both outer hair cells(OHCs)and inner hair cells(IHCs)in the mammalian co chlea.Whereas Ikzf2 is necessary for OHC development,the key gene re quired for IHC development remains unknown.We found that deletion of Tbx2 in neonatal IHCs led to their transdifferentiation into OHCs by repressing 26.7%of IHC genes and inducing 56.3%of OHC genes,including Ikzf2.More importantly,persistent expression of Tbx2 coupled with transient Atohl expression effe ctively reprogrammed non-sensory supporting cells into new IHCs expressing the functional IHC marker vGlut3.The differentiation status of these new IHCs was considerably more advanced than that previously reported.Thus,Tbx2 is essential for IHC development and co-upregulation of Tbx2 with Atohl in supporting cells represents a new approach for treating deafness related to IHC degeneration. | Zhenghong Bi Xiang Li Minhui Ren Yunpeng Gu Tong Zhu Shuting Li Guangqin Wang Suhong Sun Yuwei Sun Zhiyong Liu | 2022 | National Science Review2022，9，12： | 1 |
