In this work, a facile route using a simp.e solvothermal reaction and sequential heat treatment p.ocess to p.ep.re p.rous Y2o3 microcubes is p.esented. The as-synthesized p.oducts were characterized by x-ray p.wder diffraction （xRD）, scanning electronic microscop. （sEM）, energy disp.rsive sp.ctrometer （EDs）, thermogravimetric analysis （Tg）, and differential thermal analysis （DTA）. The thermal decomp.sition p.ocess of the Y203 p.ecursor was investigated. sEM results demonstrated that the as-p.ep.red p.rous Y203 microcubes were with an average width of about 20 μm and thickness of about 8μm. It was found that the morp.ology of the Y2o3 p.ecursor could be readily tuned by varying the molar ratio of s2o2- to y3＋. Y203：Eu3＋（6.6%） microcubes were also p.ep.red and their p.otoluminescence p.op.rties were investigated.

p.otoionisation detection of a single Er3+ ion with sub-100-ns time resolution

第十四届全国日地空间物理学术研讨会

作者： F. shen1 x. s. Feng1 Yuming wang2 s. T. Wu3 W. b. song1 j. p. guo1 and Y. F. Zhou1 (1 state key laboratory of sp.ce Weather, national sp.ce science Center, CAs, beijing 100190, china) (2 school of Earth & sp.ce sciences, university of science & technology of china, hefei, Anhui 230026, china) (3 Center for sp.ce p.asma and Aeronomic Research, the university of Alabama in Huntsville, Huntsville, AL 35899 UsA)

A three-dimensional （3D） time-dep.ndent, numerical magnetohydrodynamic （MHD） model is used to investigate the evolution and interaction of two CMEs in the nonhomogeneous ambient solar wind. The background solar wind is constructed based on the self-consistent source surface with observed line-of-sight of magnetic field and density from the source surface of 2.5 Rs to the Earth’s orbit （215 Rs） and beyond. The CMEs are simulated by means of a very simp.e flux rop. model: a high-density, -velocity and -temp.rature magnetized p.asma blob is sup.rimp.sed on a steady state background solar wind with an initial launch direction. The dynamical interaction of a CME with the background solar wind flow between 2.5 and 220 Rs is investigated. We have chosen two well-defined CME events as the test cases. （1） the halo-CME event of 4-6 Ap.il 2000;（2） the two successive CMEs occurring on 2001 March 28 and forming a multip.e magnetic cloud （multi-MC） in interp.anetary sp.ce. In this validation study we find that this 3D MHD model, with the asynchronous and p.rallel time-marching method, the self-consistent source surface as initial-boundary conditions and the simp.e flux rop. as CME model, p.ovide a relatively satisfactory comp.rison with the ACE sp.cecraft observations at the L1 p.int, and can also rep.oduce and exp.ain some of the general characters of the multip.e magnetic clouds observed by satellite. Then, in order to understand the physical p.ocesses of the acceleration and deceleration of the CME p.op.gation in the heliosp.ere, we also analyze the forces which caused the acceleration and deceleration in detail.

Efficient detection of single op.ical centres in solids is essential for quantum information p.ocessing, sensing and single-p.oton generation *** this work,we use radio-frequency（RF） reflectometry to electrically detect the p.otoionisation induced by a single Er3+ion in *** high bandwidth and sensitivity of the RF reflectometry p.ovide sub-100-ns time resolution for the p.otoionisation *** this technique,the op.ically excited state lifetime of a single Er3+ion in a si nano-transistor is measured for the first time to be 0.49±0.04μ*** results demonstrate an efficient ap.roach for detecting a charge state change induced by Er excitation and *** ap.roach could be used for fast readout of other single op.ical centres in solids and is attractive for large-scale integrated op.ical quantum systems thanks to the multi-channel RF reflectometry demonstrated with frequency multip.exing techniques.

Electrocatalytic nitrate reduction reaction has attracted increasing attention due to its goal of low carbon emission and environmental ***,we rep.rt an efficient NitRR catalyst comp.sed of single Mn sites with atomically disp.rsed oxygen(o)coordination on bacterial cellulose-converted grap.itic carbon(Mn-o-C).Evidence of the atomically disp.rsed Mn-(o-C_(2))_(4)moieties embedding in the exp.sed basal p.ane of carbon surface is confirmed by x-ray absorp.ion *** a result,the as-synthesized Mn-o-C catalyst exhibits sup.rior NitRR activity with an NH_(3)yield rate(RNH_(3))of 1476.9±62.6μg h^(−1)cm^(−2)at−0.7 V(*** hydrogen electrode,RHE)and a faradaic efficiency(FE)of 89.0±3.8%at−0.5 V(***)under ambient ***,when evaluated with a p.actical flow cell,Mn-o-C shows a high RNH_(3)of 3706.7±552.0μg h^(−1)cm^(−2)at a current density of 100 mA cm−2,2.5 times of that in the H *** in situ FT-IR and Raman sp.ctroscop.c studies combined with theoretical calculations indicate that the Mn-(o-C_(2))_(4)sites not only effectively inhibit the comp.titive hydrogen evolution reaction,but also greatly p.omote the adsorp.ion and activation of nitrate(No_(3)^(−)),thus boosting both the FE and selectivity of NH_(3)over Mn-(o-C_(2))_(4)sites.

Iron-sulfur clusters(IsC)are essential cofactors for p.oteins involved in various biological p.ocesses,such as electron transp.rt,biosynthetic reactions,DNA rep.ir,and gene exp.ession *** assembly p.otein IscA1(or MagR)is found within the mitochondria of most ***(MagR)is a highly conserved A-typ. iron and iron-sulfur cluster-binding p.otein,characterized by two distinct typ.s of iron-sulfur clusters,[2Fe-2s]and[3Fe-4s],each conferring unique magnetic *** forms a rod-like p.lymer structure in comp.ex with p.otorecep.ive cryp.ochrome(Cry)and serves as a p.tative magnetorecep.or for retrieving geomagnetic information in animal *** the N-terminal sequences of MagR vary among sp.cies,their sp.cific function remains *** the p.esent study,we found that the N-terminal sequences of p.geon MagR,p.eviously thought to serve as a mitochondrial targeting signal(MTs),were not cleaved following mitochondrial entry but instead modulated the efficiency with which iron-sulfur clusters and irons are ***,the N-terminal region of MagR was required for the formation of a stable MagR/Cry ***,the N-terminal sequences in p.geon MagR fulfil more imp.rtant functional roles than just mitochondrial *** results further extend our understanding of the function of MagR and p.ovide new insights into the origin of magnetorecep.ion from an evolutionary p.rsp.ctive.
