The insoluble β-cyclodextrin/glutaraldehyde crosslinked polyvinylpyrrolidone nanofibrous membranes were prepared by electrospinning technique. The membranes were extensively characterized by various techniques including attenuated total reflectance Fourier transform infrared spectroscopy（ATR-FTIR）, X-ray diffraction（XRD）, scanning electron microscopy（SEM） and UV-visible absorption to correlate membrane characteristics with their performance. The adsorption ability of the nanofibrous membranes was tested by performing extraction of Methyl orange（MO） dye in water. It was observed that β-cyclodextrin incorporated in polyvinylpyrrolidone provided the characteristics of high adsorption capacity of polyvinylpyrrolidone. Results of sorption experiments show that the nanofibrous membranes exhibited an adsorption rate of more than 95% for MO and the MO absorbent was 39.82 mg to per gram of fl-cyclodextrin glutaraldehyde（β-CDXFM） crosslinked PVP under the optimized experimental conditions.

In this work, we propose a high-fidelity phonon-mediated entangling gate in a hybrid mechanical system based on two silicon-vacancy color centers in diamond. In order to suppress the influence of the spin decoherence on the entangling gate, we use a continuous dynamical decoupling approach to create new dressed spin states, which are less sensitive to environmental fluctuations and exhibit an extended T_(2)^(*) spin dephasing time. The effective spin-spin Hamiltonian modified by the mechanical driving field and the corresponding master equation are derived in the dispersive regime. We show that in the presence of the mechanical driving field, the effective spin-spin coupling can be highly controlled. By calculating the entangling gate fidelity in the dressed basis, we find that once the mechanical field is turned on, the gate fidelity can be significantly improved. In particular, under an optimized spin-phonon detuning and a stronger Rabi frequency of the mechanical driving field, the two-qubit gate is capable of reaching fidelity exceeding 0.99. Moreover, by employing appropriate driving modulation, we show that a highfidelity full quantum gate can be also realized, in which the initial and final spin states are on a bare basis. Our work provides a promising scheme for realizing high-fidelity quantum information processing.

Based on conserved regions among genomic RNA of tobamoviruses, a pair of primers spanning the sequence encoding the movement protein were synthesized. A cDNA fragment of 1700bp was thus amplified by RT-PCR(reverse transcription-polymerase chain reaction). The fragment was cloned into pGEM-T easy vector and sequenced. DNA sequence analysis showed that the fragment contained a region of 768 nucleotides encoding protein of 256 amino acid of frangipani mosaic virus (FMV) and also partial sequence corresponding to 180ku and 17. 5ku protein.

WHAT used to be known as a neighborhood is now called a "community"—a civic sub-administrative body below that of "district." The change applies not only to the name but to its role as well; economic progress and changes in people’s lifestyle have called for new uses for the community—the most fundamental administrative unit in a city.

研究了总剂量辐照效应对0.35μm n型金属-氧化物-半导体(NMOS)器件热载流子测试的影响.试验结果表明:经过100 krad(Si)总剂量辐照后进行5000 s的热载流子测试,NMOS器件阈值电压随着总剂量的增大而减小,然后随热载流子测试时间的增加而增大,且变化值远远超过未经过总剂量辐照的器件;总剂量辐照后经过200 h高温退火,再进行5000 s的热载流子测试,其热载流子退化值远小于未高温退火的样品,但比未辐照的样品更明显,即总剂量辐照与热载流子的协同效应要超过两种效应的简单叠加.根据两种效应的原理分析,认为总剂量辐照感生氧化层陷阱电荷中的空穴与热电子复合减少了正氧化层的陷阱电荷,但辐照感生界面态俘获热电子形成负的界面陷阱电荷,表现为两者的协同效应模拟方式比单机理模拟方式对器件的影响更严重.
