| 1 | Electrochemical Lithium Storage Performance of Molten Salt Derived V_(2)SnC MAX Phase显示文摘MAX phases are gaining attention as precursors of two-dimensional MXenes that are intensively pursued in applications for electrochemical energy storage.Here,we report the preparation of V_(2)SnC MAX phase by the molten salt method.V_(2)SnC is investigated as a lithium storage anode,showing a high gravimetric capacity of 490 mAh g−1 and volumetric capacity of 570 mAh cm^(−3) as well as superior rate performance of 95 mAh g^(−1)(110 mAh cm^(−3))at 50 C,surpassing the ever-reported performance of MAX phase anodes.Sup-ported by operando X-ray diffraction and density functional theory,a charge storage mechanism with dual redox reaction is proposed with a Sn-Li(de)alloying reaction that occurs at the edge sites of V_(2)SnC particles where Sn atoms are exposed to the electrolyte followed by a redox reaction that occurs at V_(2)C layers with Li.This study offers promise of using MAX phases with M-site and A-site elements that are redox active as high-rate lithium storage materials. | Youbing Li Guoliang Ma Hui Shao Peng Xiao Jun Lu Jin Xu Jinrong Hou Ke Chen Xiao Zhang Mian Li Per OÅPersson Lars Hultman Per Eklund Shiyu Du Zhifang Chai Zhengren Huang Na Jin Jiwei Ma Ying Liu Zifeng Lin Qing Huang | 2021 | Nano-Micro Letters2021，13，10： | 2 |
| 2 | Ginger-indirect moxibustion plus acupuncture versus acupuncture alone for chronic fatigue syndrome:a randomized controlled trial显示文摘OBJECTIVE:To assess the efficacy and safety of gingerindirect moxibustion for chronic fatigue syndrome(CFS).METHODS:In this central randomized,controlled trial,290 CFS participants were recruited and randomly allocated to group A(ginger-indirect moxibustion plus acupuncture)or group B(acupuncture alone).The study consisted of a treatment period of 8 weeks with a total of 24 treatments(3 sessions per week,every other day),and a follow-up period of 12 weeks.The outcome was measured by Fatigue Severity Scale(FSS),Psychological Health Report(SPHERE),the Self-rating depression scale(SDS)and the Hamilton anxiety scale(HAMA)at baseline,2,4,6,8,12 and 20 weeks.RESULTS:With the treatment undergoing,the changes of FSS,SPHERE,SDS and HAMA scores in both groups increased gradually,and the effect maintained at the 12th week.Between groups,significantly higher score changes were seen in group A in FSS after 4 weeks treatment(11.94 vs 9.12,95%CI:0.94,4.7)and in SPHERE after 2 weeks treatment(3.7 vs 2.27,95%CI:0.56,2.31).But for SDS and HAMA,the improvement did not differ significantly between groups.No severe adverse events were reported.CONCLUSION:Ginger-indirect moxibustion is a safe and effective intervention to relieve fatigue and accompanying physical symptoms of CFS. | MA Tingting WU Jie YANG Lijie FENG Fen YANG Huilin ZHANG Jinhua ZHONG Yanjin NING Qing HUANG Lirong LIN Youbing YAN Jue CHEN Guiquan HOU Tianshu WANG Li REN Yuanfang TAN Jing | 2022 | Journal of Traditional Chinese Medicine2022，42，2： | 2 |
| 3 | A Fault Risk Warning Method of Integrated Energy Systems Based on RelieF-Softmax Algorithm显示文摘The integrated energy systems,usually including electric energy,natural gas and thermal energy,play a pivotal role in the energy Internet project,which could improve the accommodation of renewable energy through multienergy complementary ways.Focusing on the regional integrated energy system composed of electrical microgrid and natural gas network,a fault risk warning method based on the improved RelieF-softmax method is proposed in this paper.The raw data-set was first clustered by the K-maxmin method to improve the preference of the random sampling process in the RelieF algorithm,and thereby achieved a hierarchical and non-repeated sampling.Then,the improved RelieF algorithm is used to identify the feature vectors,calculate the feature weights,and select the preferred feature subset according to the initially set threshold.In addition,a correlation coefficient method is applied to reduce the feature subset,and further eliminate the redundant feature vectors to obtain the optimal feature subset.Finally,the softmax classifier is used to obtain the early warnings of the integrated energy system.Case studies are conducted on an integrated energy system in the south of China to demonstrate the accuracy of fault risk warning method proposed in this paper. | Qidai Lin Ying Gong Yizhi Shi Changsen Feng Youbing Zhang | 2022 | Computer Modeling in Engineering & Sciences2022，，9： | 0 |
| 4 | Molten Salt-Shielded Synthesis(MS^(3))of MXenes in Air显示文摘MXenes are two-dimensional transition metal carbides and/or nitrides with unique physiochemical properties and have attracted extensive interest in numerous fields.However,current MXene synthesis methods are limited by hazardous synthesis conditions,high production costs,or difficulty in largescale production.Therefore,a general,safe,cost-effective,and scalable synthesis method for MXenes is crucial.Here,we report the fast synthesis of MXenes in the open air using a molten salt-shielded synthesis(MS^(3))method,which uses Lewis-acid salts as etchants and a low-melting-point eutectic salt mixture as the reaction medium and shield to prevent MXene oxidation at high temperatures.Carbide and nitride MXenes,including Ti_(3)C_(2)T_(x),Ti_(2)CT_(x),Ti_(3)CNT_(x),and Ti_(4)N_(3)T_(x),were successfully synthesized using the MS^(3) method.We also present the flexibility of the MS^(3) method by scaling the etching process to large batches of 20 and 60 g of Ti_(3)AlC_(2) MAX precursor in one pot.When used as negative electrodes,the prepared MS^(3)-MXenes delivered excellent electrochemical properties for high-rate Li-ion storage. | Jinjin Chen Qianqian Jin Youbing Li Hui Shao Pengcheng Liu Ying Liu Pierre-Louis Taberna Qing Huang Zifeng Lin Patrice Simon | 2023 | Energy & Environmental Materials2023，6，2： | 0 |
