| 1 | Stable wide-temperature and low volume expansion Al batteries:Integrating few-layer graphene with multifunctional cobalt boride nanocluster as positive electrode显示文摘To achieve stable positive electrode for promoting the overall electrochemical performance of Al batteries(ABs),here novel cobalt boride(CoB)nanoclusters are synthesized to construct composite electrodes with few-layer graphene(FLG).Due to the presence of amorphous channels in the employed CoB nanoclusters,the ABs with FLG/CoB composite positive electrodes exhibit high rate.capability and both mechanical and electrochemical stability in the ABs.With assistance of in situ scanning electron microscopy(SEM),the observation results suggest that the positive electrode of CoB nanoclusters holds almost ignorable volume variation upon electrochemical processes,which substantially alleviates the massive electrode expansion induced by the anion intercalation in the composite positive electrode.Interestingly,the composite positive electrodes provide stable reversible energy storage capability within a broadened temperature range(-30-60℃),promising a novel strategy to design advanced ABs positive electrodes with enhanced overall energy storage performance. | Li-Li Chen Na Li Huifeng Shi Yuefei Zhang Wei-Li Song Shuqiang Jiao Haosen Chen Daining Fang | 2020 | Nano Research2020，13，2： | 2 |
| 2 | Future Research Trend for Improving Large Reflector Antenna Service Performance显示文摘A large reflector antenna is one of the key components of a deep space telemetry track and command(TT&C)network,which is of great importance for human space activities,such as satellite communication,spaceflight,and deep space exploration[1].The main feature of this antenna type is its large aperture and often it requires strict surface accuracy to ensure high gain and high pointing performance[2,3].There are two kinds of reflector antennas:non-fully movable antenna and fully steerable antenna.The Fivehundred-meter Aperture Spherical Radio Telescope in China is one representative non-fully movable antenna with a super large aperture and low operation frequency.The fully steerable reflector antennas worldwide can be further divided into four categories according to their aperture diameters and highest operation frequencies,as shown in Fig.1.Most of the antennas in Fig.1 can be found in Ref.[4]and the details are not presented here.Category 1 includes the traditional reflectors with large apertures and low operation frequencies. | Peiyuan Lian Congsi Wang Song Xue Yan Wang Yuefei Yan Qian Xu Baoyan Duan Na Wang Yuhu Duan Yang Wu | 2021 | Engineering2021，7，8： | 2 |

| 4 | Hybrid-panel-based new design idea for large reflector antenna显示文摘Large reflector antennas are widely used as radio telescopes and active main reflectors are generally applied to improve the surface accuracy. Considering that the high cost has been one important problem in engineering, it is worth discussing whether it is necessary to install actuators on all the panels. Thus, in this paper, a hybrid-panel-based new design idea for large reflector antenna is proposed. Assuming that the actuators are installed only in the region of the reflector with large deformations and there are no actuators in other region to reduce the actuator number, the surface accuracies and the corresponding electromagnetic(EM) performances calculated by three different panel adjustment strategies are compared. The most effective method is that the deformed reflector should be first preadjusted to reduce the gravity deformation and then the panels equipped with actuators should be adjusted to the locations determined by the best fitting reflector(BFR) derived by the deformed reflector with no actuators. A 35 m reflector antenna is adopted as an example to calculate the surface accuracy and EM performance when parts of the panels are equipped with actuators. The simulation results show that there is no need to install actuators on all panels and the presented method can greatly reduce the number of actuators with guaranteed surface accuracy. Thus, during the antenna structural design phase, once the surface accuracy requirement is given, the number of actuators can be minimized to reduce the manufacturing and maintenance costs as much as possible. This paper can provide valuable guidance for the design of an active main reflector with hybrid panels. | LIAN PeiYuan YAN YueFei WANG CongSi QIN Long XUE Song WANG Na XU Qian ZHAO WuLin ZHENG YuanPeng | 2023 | Science China(Technological Sciences)2023，66，1： | 1 |

| 7 | Accurate Data Match and Call Method for the Thermal Compensation Database of the Reflector Antenna显示文摘The influence of thermal deformation on the performance of reflector antennas has become increasingly significant with the increasing aperture and working frequency.The use of a thermal compensation database is an efficient method to compensate for the deformation caused by the non-uniform temperature distribution.However,how to efficiently and accurately match and call the database remains as one of the tough challenges for the antenna thermal compensation system to achieve real time compensation.Therefore,this study proposes a data match and call method for the thermal compensation database of the reflector antenna,matching the database from three aspects:the overall rms match of temperature data,the similarity area match of each data sample,and the key area match of key structural positions.The validation of this method is demonstrated in an example.The difference between the pointing adjustment amount calculated by the matched data and the collected data was found to be less than 1',which satisfied the requirements of practical engineering,thus achieving real-time thermal compensation of the antenna. | Yuefei Yan Song Xue Xinlan Hu Peiyuan Lian Yan Wang Lin Li Qian Xu Na Wang Wulin Zhao Yuanpeng Zheng Congsi Wang | 2022 | Research in Astronomy and Astrophysics2022，22，5： | 0 |
| 8 | Effects of Diesel Concentration on the Thermal Conductivity,Specific Heat Capacity and Thermal Diffusivity of Diesel-Contaminated Soil显示文摘High energy consumption is a serious issue associated with in situ thermal desorption(TD)remediation of sites contaminated by petroleum hydrocarbons(PHs).The knowledge on the thermophysical properties of contaminated soil can help predict accurately the transient temperature distribution in a remediation site,for the purpose of energy conservation.However,such data are rarely reported for PH-contaminated soil.In this study,by taking diesel as a representative example for PHs,soil samples with constant dry bulk density but different diesel mass concentrations ranging from 0% to 20% were prepared,and the variations of their thermal conductivity,specific heat capacity and thermal diffusivity were measured and analyzed over a wide temperature range between 0℃ and 120℃.It was found that the effect of diesel concentration on the thermal conductivity of soil is negligible when it is below 1%.When diesel concentration is below 10%,the thermal conductivity of soil increases with raising the temperature.However,when diesel concentration becomes above 10%,the change of the thermal conductivity of soil with temperature exhibits the opposite trend.This is mainly due to the competition between soil minerals and diesel,because the thermal conductivity of minerals increases with temperature,whereas the thermal conductivity of diesel decreases with temperature.The analysis results showed that,compared with temperature,the diesel concentration has more significant effects on soil thermal conductivity.Regardless of the diesel concentration,with the increase of temperature,the specific heat capacity of soil increases,while the thermal diffusivity of soil decreases.In addition,the results of a control experiment exhibited that the relative differences of the thermal conductivity of the soil samples containing the same concentration of both diesel and a pure alkane are all below 10%,indicating that the results obtained with diesel in this study can be extended to the family of PHs.A theoretical prediction model was proposed based on cubic fractal and thermal resistance analysis,which confirmed that diesel concentration does have a significant effect on soil thermal conductivity.For the sake of practical applications,a regression model with the diesel concentration as a primary parameter was also proposed. | WU Yuhao WU Yuefei LUO Gubai ZHANG Teng WANG Qing FAN Liwu SONG Xin YU Zitao | 2024 | Journal of Thermal Science2024，33，2： | 0 |
| 9 | Nanoplateletsomes for rapid hemostasis performance显示文摘Uncontrollable hemorrhage remains staple trouble in surgical procedures and a leading cause after major trauma.The bleeding issue may trigger various pathologic scenarios that can lead to tissue morbidities and mortalities,and currently available on-site hemostatic agents are confined to a narrow therapeutic index and may carry the risk of immunogenicity.Inspired by the crucial role of platelets in the process of thrombus,a platelet-mimetic plateletsome with wound targeting and blood coagulation properties is developed for hemorrhage control.Plateletsome is formulated by integrating platelet membranes with functionalized synthetic liposomes and exhibits superior wound targeting and effective hemostasis properties.It presents less blood loss and shorter hemostasis time than the platelet membrane vehicles or the conventional liposomes in the mouse tail transection model.The strong homing of the biomimetic plateletsome to the thrombus was also confirmed,demonstrating the potential of this engineered cell membrane vesicle as a biomimetic hemostat for bleeding treatment. | Honglan Wang Yuefei Zhu Longlong Zhang Huiwen Liu Chunying Liu Bo Zhang Yanan Song Yu Hu Zhiqing Pang | 2022 | Chinese Chemical Letters2022，33，6： | 0 |
