2Disposable paper-based bipolar electrode array for multiplexed electrochemiluminescence detection of pathogenic DNAs显示文摘A novel disposable paper-based bipolar electrode(BPE) array is fabricated for multiplexed electrochemiluminescence(ECL) detection of pathogenic DNAs. This proposed BPE array device consists of 15 units, each consisting of six sensing cells and two reporting cells patterned using hydrophobic wax. A hairpin structure DNA assembled on the cathodes of BPEs hybridizes with Pt nanoparticles(NPs) labeled probe DNA in the presence of complementary target DNA. The introduction of Pt NPs catalyzes the reduction of dissolved O2 at cathodes and induces an enhanced ECL signal from Ru(bpy)32+/tripropylamine(TPr A) at the anodes of BPEs. The dissolved O2 lost in reduction reaction could be promptly replenished due to the relatively large contact area of the paper-based cells with air, which ensures the stability of ECL signal. This obtained paper-based BPE array sensor showed excellent performances for the multiplexed analysis of the syphilis(Treponema pallidum) gene, the immunodeficiency virus gene(HIV) and hepatitis B virus gene(HBV).Qiumei Feng Hongyuan Chen Jingjuan Xu 2015Science China Chemistry2015,58,5:2
3Assembly-promoted photocatalysis:Three-dimensional assembly of CdS_(x)Se_(1-x)(x=0-1) quantum dots into nanospheres with enhanced photocatalytic performance显示文摘In this paper,through an emulsion-based bottom-up self-assembly method,monodisperse CdS_(x)Se_(1-x)(x=0-1)quantum dots(QDs)with tailoring compositions have been three-dimensionally assembled into spherical architectures in sub-micrometer sizes.UVeVis absorption measurements revealed the enhanced light harvesting abilities of the assembled CdS_(x)Se_(1-x) spheres relative to their constituting QDs.HRTEM characterizations over the CdS_(x)Se_(1-x) assemblies suggested the existence of localized oriented adjoining of the CdS_(x)Se_(1-x) QDs and the resulting nano-twin structures that are favorable for photogenerated electron-hole separation.The quenching of photoluminescence and the improvement in IPCE after the assembly of CdS_(x)Se_(1-x) QDs provided a clue to the likely suppressed electron-hole recombination brought about by the unique architectures and interfaces derived from self-assembly.The above findings were coincided with the remarkably improved H2 evolution activities observed for the wellassembled CdS_(x)Se_(1-x) nanospheres in photocatalytic water splitting,underpinning the importance of the alternative strategy to design advanced semiconductor photocatalysts based on architectural engineering.Lina Wang Qiumei Di Mingming Sun Jia Liu Chuanbao Cao Jiajia Liu Meng Xu Jiatao Zhang 2017Journal of Materiomics2017,3,1:2

5Compressive surface strained atomic-layer Cu2O on Cu@Ag nanoparticles显示文摘Control of surface structure at the atomic level can effectively tune catalytic properties of nanomaterials.Tuning surface strain is an effective strategy for enhancing catalytic activity;however,the correlation studies between the surface strain with catalytic performance are scant because such mechanistic studies require the precise control of surface strain on catalysts.In this work,a simple strategy of precisely tuning compressive surface strain of atomic-layer Cu2O on Cu@Ag (AL-Cu2O/Cu@Ag) nanoparticles (NPs) is demonstrated.The AL-Cu2O is synthesized by structure evolution of Cu@Ag core-shell nanoparticles,and the precise thickness-control of AL-Cu2O is achieved by tuning the molar ratio of Cu/Ag of the starting material.Aberration-corrected high-resolution transmission electron microscopy (AC-HRTEM) and EELS elemental mapping characterization showed that the compressive surface strain of AL-Cu2O along the [111] and [200] directions can be precisely tuned from 6.5% to 1.6% and 6.6% to 4.7%,respectively,by changing the number of AL-Cu2O layer from 3 to 6.The as-prepared AL-Cu2O/Cu@Ag NPs exhibited excellent catalytic property in the synthesis of azobenzene from aniline,in which the strained 4-layers Cu2O (4.5% along the [111] direction,6.1% along the [200] direction) exhibits the best catalytic performance.This work may be beneficial for the design and surface engineering of catalysts toward specific applications.Xiyue Zhu Hongpan Rong Xiaobin Zhang Qiumei Di Huishan Shang Bing Bai Jiajia Liu Jia Liu Meng Xu Wenxing Chen Jiatao Zhang 2019Nano Research2019,12,5:1
64-14 Production of Projectile and Target K-vacancy in Near-symmetric Collisions by 60100 MeV Cu9+ Ions with Thin Zn Target显示文摘The study on ion-solid collisions has important significances not only for fundamental researches but also for technical applications, like ion-beam modification and analysis of surfaces[1]. So far, K-shell ionization has beenmost widely studied for large range of projectile number and incident energy[2;3]. However, even today, a complete theory that can predict K-shell vacancy production for all collision systems in different velocities is still lacking, especially at an intermediate energy.Guo Yipan Yang Zhihu Du Shubin Chang Hongwei Xia Qingliang Xu Qiumei 2015IMP & HIRFL Annual Report2015,,1:0
74-20 Light Emission from Sputtered Aluminum Atoms and Ions Produced by Kr13+ Ion Bombardment显示文摘When solid surface is bombarded by energetic projectile ions, a fraction of the sputtered particles leaves the surface in electronically excited states. The optical emission in front of the target surface is due to the radiative decay of these sputtered particles[1;2]. The optical emission identifies the target by measurement of wavelength.Xu Qiumei Guo Yipan 2015IMP & HIRFL Annual Report2015,,1:0

9Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.Angel Abusleme Thomas Adam Shakeel Ahmad Sebastiano Aiello Muhammad Akram Nawab Ali Fengpeng An Guangpeng An Qi An Giuseppe Andronico Nikolay Anfimov Vito Antonelli Tatiana Antoshkina Burin

10An accurate a posteriori error estimator for the Steklov eigenvalue problem and its applications显示文摘In this paper, a type of accurate a posteriori error estimator is proposed for the Steklov eigenvalue problem based on the complementary approach, which provides an asymptotic exact estimate for the approximate eigenpair. Besides, we design a type of cascadic adaptive finite element method for the Steklov eigenvalue problem based on the proposed a posteriori error estimator. In this new cascadic adaptive scheme, instead of solving the Steklov eigenvalue problem in each adaptive space directly, we only need to do some smoothing steps for linearized boundary value problems on a series of adaptive spaces and solve some Steklov eigenvalue problems on a low dimensional space. Furthermore, the proposed a posteriori error estimator provides the way to refine meshes and control the number of smoothing steps for the cascadic adaptive method. Some numerical examples are presented to validate the efficiency of the algorithm in this paper.Fei Xu Qiumei Huang 2021Science China Mathematics2021,64,3:0
11Site-directed mutagenesis of long QT syndrome KCNQ1 gene in vitro显示文摘To construct a polymerase chain reaction(PCR)site-directed mutagenesis of the long QT syndrome KCNQ1 gene in vitro,two sets of primers were designed according to the sequence of KCNQ1 cDNA and a mismatch was introduced into primers.Mutagenesis was performed in a two-step PCR.The amplified fragments from the third PCR which contained the mutation site were sub-cloned into the T-vector pCR2.1.Then,the fragments containing the mutation site was obtained from pCR2.1 using restriction enzymes digestion and inserted into the same restriction site of pIRES2-EGFP-KCNQ1.The sequencing analysis shows that the mutation site was correct.Mutation from A to G in site 983 of KCNQ1 cDNA was found.Using the Effectene transfection reagent,pIRES2-EGFP-KCNQ1(G983A)was transfected into HEK cells successfully.These results may shed light on further functional study of KCNQ1 gene.Wei LI Junguo YANG Rong DU Li TIAN Bin WANG Qiumei XU Qinmei KE Qing WANG 2008Frontiers of Medicine2008,2,1:0
12Luminescent Cu doped CdTe nanocrystals via cation exchange of Cu_(7)Te_(5)nanocubes:From undoped to doped emission显示文摘InⅡ-Ⅵgroup,the doping in CdTe nanocrystals(NCs)is more difficult than other chalcogenides.In this communication,CdTe nanocrystals containing Cu impurities were carefully synthesized based on controlled reverse cation exchange process between as-prepared Cu_(7)Te_(5)nanocubes and Cd^(2+)ions.By well-defined Cu_(7)Te_(5)nanocubes,the obtained CdTe NCs kept the original morphology.The concentration of Cu impurities in CdTe NCs was controlled by the regulation such reverse cation exchange.Additionally,the regulation from band gap(BG)photo luminescence(PL)to the coexistence of the bandgap emission,dopant emission,and surface-state emission was realized.This tailoring from undoped to doped emission in the case of Cu impurities is helpful to study the Cu related doping in telluride NCs.Jiaojiao Zheng Bing Bai Qiumei Di Zhuoli Jiang Meng Xu Jiatao Zhang 2021Progress in Natural Science:Materials International2021,31,3:0
