| 1 | Physics-informed neural network approach for heat generation rate estimation of lithium-ion battery under various driving conditions显示文摘Accurate insight into the heat generation rate(HGR) of lithium-ion batteries(LIBs) is one of key issues for battery management systems to formulate thermal safety warning strategies in advance.For this reason,this paper proposes a novel physics-informed neural network(PINN) approach for HGR estimation of LIBs under various driving conditions.Specifically,a single particle model with thermodynamics(SPMT) is first constructed for extracting the critical physical knowledge related with battery HGR.Subsequently,the surface concentrations of positive and negative electrodes in battery SPMT model are integrated into the bidirectional long short-term memory(BiLSTM) networks as physical information.And combined with other feature variables,a novel PINN approach to achieve HGR estimation of LIBs with higher accuracy is constituted.Additionally,some critical hyperparameters of BiLSTM used in PINN approach are determined through Bayesian optimization algorithm(BOA) and the results of BOA-based BiLSTM are compared with other traditional BiLSTM/LSTM networks.Eventually,combined with the HGR data generated from the validated virtual battery,it is proved that the proposed approach can well predict the battery HGR under the dynamic stress test(DST) and worldwide light vehicles test procedure(WLTP),the mean absolute error under DST is 0.542 kW/m^(3),and the root mean square error under WLTP is1.428 kW/m^(3)at 25℃.Lastly,the investigation results of this paper also show a new perspective in the application of the PINN approach in battery HGR estimation. | Hui Pang Longxing Wu Jiahao Liu Xiaofei Liu Kai Liu | 2023 | Journal of Energy Chemistry2023，，3： | 2 |
| 2 | Low-cost and low-density carbonized facial tissue supported uniform NiCo_(2)S_(4)nanotubes for high capacity flexible solid-state supercapacitors显示文摘Recently,rapid development of intelligent wearable electronic equipment has triggered great needs for flexible and lightweight portable energy storage systems.Here,we demonstrate a low-cost($0.5 m^(-2))and low density carbonized facial tissue paper(FCP)for high-conductive NiCo_(2)S_(4)nanotubes assisted novel ultra-flexible solid-state supercapacitors(SSCs).The hydrothermal synthesized FCP-900@NiCo_(2)S_(4)electrodes in this paper only have a density of 5 mg cm^(-2)and show large specific capacitance of 3115 mF cm^(-2)at 2 mA cm^(-2).Based on the high performance of FCP-900@NiCo_(2)S_(4)electrodes,the as assembled SSCs can deliver an energy density of 1.2 mWh cm^(-3),high power density of 58.16 mW cm-3.It also shows great bending-state capacitive performance with high capacitance retention after 5000 cycles,providing a new opportunity for developing high-performance flexible wearable energy storage devices. | Haiwei Wu Jingxuan Bi Yiyi Li Li Wang Xiaofei Pang Chuanyin Xiong Zhijian Li | 2021 | Journal of Materiomics2021，7，1： | 1 |

| 5 | Magnetocardiograph as a noninvasive and radiation-free diagnostic device for myocardial infarction:a systematic review and meta-analysis显示文摘Background:This study aimed to evaluate the diagnostic accuracy of magnetocardiograph,a relatively new noninvasive device,in patients with myocardial infarction(MI).Methods:To identify studies assessing the diagnostic accuracy of magnetocardiography for MI,we searched four databases on November 7,2022,the Cochrane Central Register of Controlled Trials,MEDLINE,EMBASE,and Web of Science,plus ClinicalTrials.gov.Three reviewers screened the studies independently and emailed the authors for more precise data when necessary.The Quality Assessment of Diagnostic Accuracy Studies 2 tool was used to evaluate the quality of the included studies.STATA(version 17;Stata Corporation,College Station,TX,USA)was used for meta-analysis of 22 contingency table data.Results:A total of 6 articles were included in this study.The diagnostic parameters of all included studies were summarized as follows:the pooled sensitivity was 0.91(95%confidence intervals[95%CIs]:0.81–0.96;I 2=88.54);specificity was 0.83(95%CI:0.75–0.89;I 2=83);positive likelihood ratio was 5.3(95%CI:3.5–8.2);negative likelihood ratio was 0.1(95%CI:0.04–0.24);and diagnostic odds ratio was 51(95%CI:16–161).The area under the curve for the receiver operating characteristic curve was 0.92(95%CI:0.89–0.94).After metaregression analysis,we found that the number of channels and the way of environmental magnetic noise elimination were heterogeneous sources.Conclusion:In summary,our meta-analysis shows that magnetocardiography holds a high accuracy in diagnosing MI and takes the advantages of noninvasive,radiation-free,and noncontact.However,further high-quality studies to confirm its usefulness in diagnosing MI are warranted. | Yansong Xu Xiaole Han Mingyue Guo Ruochuan Li Yiming Dong Jiaxin Fan Xiaofei Yin Fei Xie Jiaojiao Pang Yuguo Chen | 2023 | Emergency and Critical Care Medicine2023，3，2： | 0 |
| 6 | Enhanced monopole transition strength from the cluster decay of ^(13)C显示文摘The inelastic excitations and cluster decay of ^(13)C have been measured using the reaction,9Be(^(13)C, ^(13)C* →~9Be + α)~9Be. We observe strong excitation to the 14.3-MeV(1/2-) resonant state from the cluster-decay channel, leading to an enhanced monopole matrix element of(6.3 ± 0.6) fm^2. This large cluster-related monopole strength is a clear indication of the cluster-structure domination of this state and is consistent with the recent prediction of the orthogonality condition model(OCM). It would be interesting to further explore the three-center molecular rotational band that is initiated from the observed band-head. | Jun Feng YanLin Ye Biao Yang ChengJian Lin HuiMin Jia DanYang Pang ZhiHuan Li JianLing Lou QiTe Li XiaoFei Yang Jing Li HongLiang Zang Qiang Liu Wei Jiang ChenGuang Li Yang Liu ZhiQiang Chen HongYi Wu ChunGuang Wang Wei Liu Xiang Wang JingJing Li DiWen Luo Ying Jiang ShiWei Bai JinYan Xu NanRu Ma LiJie Sun DongXi Wang | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，1： | 0 |
| 7 | Magnetic property recovery in Nd-Fe-B bonded magnet wastes with chemical reaction and physical dissolution显示文摘The main difficulty for the recovery of Nd-Fe-B bonded magnet wastes is how to completely remove the epoxy resins.In this study,chemical reaction and physical dissolution were combined to remove the epoxy resins by adding ammonia-water and mixed organic solvents.Ammonia-water can react with the epoxy functional group of epoxy resin to generate polyols.Mixed organic solvents of alcohol,dimethyl formamide(DMF),and tetrahydrofuran(THF) can dissolve the generated polyols and residual epoxy resins.Under the optimum processing conditions,the epoxy resins in the waste magnetic powders are substantially removed.The oxygen and carbon contents in the recycled magnetic powder are reduced from 13500 × 10^(-6) to 1600 × 10^(-6) and from 19500 × 10^(-6) to 2100 × 10^(-6) with the reduction ratio of88.1% and 89.2%,respectively.The recycled magnetic powder presents improved magnetic properties with MS of 1.306 × 10^(-1) A·m^(2)/g,Mr of 0.926 × 10^(-1) A·m^(2)/g,Hcj of 1.170 T,and(BH)max of 125.732 kJ/m^(3),which reach 99.8%,99.4%,95.9%,and 96.9% of the original magnetic powders,respectively. | Min Liu Haiyuan Cui Qingyan Li Peihong Zhu Weiqiang Liu Qingmei Lu Dongtao Zhang Zaisheng Pang Xi Yu Chunhui Yu Shanshun Zha Youhao Liu Xiaofei Yi Ming Yue | 2021 | Journal of Rare Earths2021，39，11： | 0 |
| 8 | Geochronology and Geochemistry of Early Cretaceous A-type Granites in Central-Eastern Inner Mongolia,China:Implications for Late Mesozoic Tectonic Evolution of the Southern Great Xing'an Range显示文摘The southern Great Xing'an Range is the most critical Sn-polymetallic metallogenic belt in northeast China.However,the tectonic setting of the Early Cretaceous magmatic-metallogenic”flare-up“event remains uncertain.This paper presents an integrated study on the occurrence,petrology,zircon U-Pb ages,whole-rock geochemistry,and in situ zircon Hf isotopes for Wenduerchagan granites of Xi Ujimqin Banner,central-eastern Inner Mongolia.These granites consist primarily of granite porphyry(with ages of 137±1 Ma and 138±1 Ma)and(porphyritic)alkali feldspar granite(with an age of 141±2 Ma),corresponding to the early Early Cretaceous.They are A-type granites characterized by high silicon,alkali,and TFeO/MgO contents while being depleted of Ba,Nb,Ta,Sr,P,and Ti.They show right-dipping trend rare-earth element distribution characteristics with negative Eu anomalies(Eu/Eu^(*)=0.01-0.20)and weak heavy rare-earth element fractionation((Gd/Yb)_(N)=0.77-2.30).They demonstrate homogeneous zircon Hf isotopic compositions(positiveε_(Hf)(t)values from+5.3 to+7.1 and young two-stage Hf model ages of 851-742 Ma)and high zircon saturation temperatures(av.810℃).These geochemical characteristics indicate that Wenduerchagan granites originated from the partial melting of juvenile crust under high-temperature and low-pressure conditions.Wenduerchagan granites most likely formed in a post-collisional compression-extension transition regime caused by the closure of the Mongol-Okhotsk Ocean,when combined with regional geology.Such a transition regime can probably be attributed to the upwelling of the asthenospheric mantle caused by the break-off of a subducted Mongol-Okhotsk oceanic slab.Upwelling asthenospheric mantle provided sufficient energy and favorable tectonic conditions for magmatism and mineralization of the Early Cretaceous. | ZHANG Yanwen ZHANG Xiaofei CHEN Lixin PANG Zhenshan CHEN Hui XUE Jianling ZHOU Yi TENG Chao CHEN Guochao | 2023 | Acta Geologica Sinica(English Edition)2023，97，4： | 0 |
