3Real-time vehicle-to-grid control for frequency regulation with high frequency regulating signal显示文摘The large-scale popularization of electric vehicles(EVs)brings the potential for grid frequency regulation.Considering the characteristics of fast response and adjustment of EVs,two control strategies of automatic generation control(AGC)with EVs are proposed responding to two high frequency regulating signals extracted from area control error(ACE)and area regulation requirement(ARR)by a digital filter,respectively.In order to dispatch regulation task to EVs,the capacity of regulation is calculated based on maximum V2G power and the present V2G power of EVs.Finally,simulations based on a two-area interconnected power system show that the proposed approaches can significantly suppress frequency deviation and reduce the active power output of traditional generation units.H.Liu K.Huang Y.Yang H.Wei S.Ma 2018Protection and Control of Modern Power Systems2018,3,1:0
4Structure and topological transport in Pb-doping topological crystalline insulator SnTe(001)film显示文摘Topological crystalline insulator(TCI)as a new type of topological materials has attracted extensive research interests for its tunable topological properties.Due its symmetry topological protection essence,the structure investigation provides a solid basement for tuning its topological transport properties.On SrTiO3(111)substrate,the SnTe film was found to be epitaxial growth only along[001]while not[111]direction.The detailed structural study was performed and a structural model was proposed to elucidate epitaxial growth of the SnTe(001)film.The transport properties of SnTe(001)film were further investigated and a typical weak anti-localization effect was observed.By Pb-doping into SnTe,the bulk carriers were inhibited and its topological surface states were strengthened to induce the enhanced surface transport contribution.With tunable multiple transport channels from the even Dirac cones,the TCI SnTe film systems will have the potential application in future spintronics devices.C.H.Yan F.Wei Y.Bai F.Wang A.Q.Zhang S.Ma W.Liu Z.D.Zhang 2020Journal of Materials Science & Technology2020,44,9:0
5Study of Dynamics of the Cross-linkinc Process of Hyperbranched Polymers显示文摘1 Results The description of the relaxation properties of polymers is the way to characterizate the influence of the polymer structure on its useful properties: stability and persistence. Synthesis and investigation of model compounds are needed to perform the physico-chemical characteristics of polymers. Instrumental methods as NMR and dielectric spectroscopy, thermogravimetric analysis and mechanical spectroscopy are used to this goal[1,2]. Dynamic mechanical thermal analysis (DMTA) is one of the most...W.W.Sulkowski S.MALanka A.Sulkowska 2007复旦学报(自然科学版)2007,46,5:0
6A new scale for optimized cryogenic magnetocaloric effect in ErAl_2@Al_2O_3 nanocapsules显示文摘The Er Al_2@Al_2O_3nanocapsules with Er Al_2core and Al_2O_3shell were synthesized by modified arc-charge technique.The typical core-shell structure of the nanocapsules was confirmed by high resolution transmission electron microscopy and X-ray photoelectron spectroscopy.Transmission electron microscopy analysis shows the irregular sphere of the nanocapules with an average diameter of 26 nm.Magnetic investigation revealed the Curie temperature of Er Al_2@Al_2O_3nanocapsules at 20 K and the typical superparamagnetic behavior between blocking temperature and Curie temperature.Based on the blocking temperature and average diameter,the magnetocrystalline anisotropy constant of Er Al_2@Al_2O_3nanocapsules was estimated to illustrate the magnetic contribution to the-S_M.The large-S_Mof 14.25 J/(kg K)was obtained under 50 k Oe at 5 K.A vital parameterˇwas introduced in the present work to scale the optimized magnetic characteristics and the optimized mechanism was discussed in detail according to classical superparamagnetic theory.The results demonstrate that the optimal-S_Mwill be obtained when the magnetic parameterˇis close to the theoretical coefficient.F.Wei S.Ma L.Yang Y.Feng J.Z.Wang A.Hua X.G.Zhao D.Y.Geng Z.D.Zhang 2018Journal of Materials Science & Technology2018,34,5:0
7白介素-21趋化因子受体CCR9辅助T细胞亚群选择性影响消化系统的附属器官显示文摘澳大利亚科学家的最新研究描述了一种CD4+辅助T细胞亚群,其特征是同时表达白介素-21和内脏寻的趋化因子受体CCR9。CCR9+辅助T细胞虽然在健康的老鼠和人身上也有发现,但在糖尿病老鼠模型发炎的胰腺和唾液腺,以及Sjgren's综合症患者中特别多。CCR9+辅助T细胞表达大量的白介素-21、可诱导的T细胞共刺激分子以及转录因子Bcl6和Maf,同时也支持B细胞的抗体生产,因此类似Tfh细胞。不过,相比于Tfh细胞,CCR9+辅助T细胞只表达有限的CXCR5,而且CCR9+辅助T细胞的目标是CD8+T细胞,后者对白介素-21的响应是糖尿病发展必须的。因此,CCR9+辅助T细胞是一类生产白介素-21的辅助T细胞,影响针对消化系统附属器官的自身免疫疾病的区域特异性。该类细胞因此可能在糖尿病发病中起关键作用。该发现对研究糖尿病的发病机理提供了新的线索。Helen M.McGuire Alexis Vogelzang Cindy S.Ma 2011中国烧伤创疡杂志2011,23,4:0
