Zn0.95Co0.05O and Zn0.91Co0.05Cu0.04O thin films were fabricated on Si（111） substrate by the reactive magnetron sputtering method at different O-Ar *** characterizations by X-ray diffractometry（XrD）,X-ray photo-electronic spectrum（XpS）, and electron paramagnetic resonance（Epr） indicate that the doped Cu ions substitute the Zn2+ions in the ZnO *** doped Cu ions are in Cu+and Cu2+mixture valence *** ferromagnetism of the Zn0.91Co0.05Cu0.04O film increases gradually the increasing Cu+ions *** results indicate that the increase of ferromagnetism is not owing to the magnetic contribution of Cu+ions themselves,but owing to the enhancement of magnetic interaction between Co ions,which suggests that p-type doping of Cu+ions plays an important role in mediating the ferromagnetic coupling between Co ions.

将微纳米气泡发生装置与膜性能检测设备联合,设计了一种微纳米气泡(MNBs)抑制膜污染的测试方法,系统研究了通入MNBs前后,MNBs对聚偏氟乙烯(pVDF)膜渗透、过滤和抗污染性的影响效果.研究结果表明,MNBs的通入使得pVDF膜的通量衰减速率降低约63.4%,截留率也提升了约21.3%.通过分析污染前后的膜表面微观形貌的扫描电子显微镜(SEM)图片可得,MNBs能有效抑制污染物滤饼层的形成和对膜孔的堵塞,有效抑制了污染物对膜的直接粘附.纳米颗粒追踪(NTA)的结果显示,通入MNBs后污染物颗粒粒径增大,这可能是MNBs对污染物的吸附作用使得污染物在MNBs表面聚集所导致.因此,MNBs抑制膜污染的机理在于,MNBs表面吸附聚集污染物,导致粒径增大,并以“汽桥”(gas-bridge)形式隔绝污染物与膜表面相互作用.

The evolution of ablative rayleigh–Taylor instability(ArTI)induced by single-mode stationary and time-varying perturbations in heat flux is studied numerically in two *** with the stationary case,time-varying heat-flux perturbation mitigates ArTI growth because of the enhanced thermal smoothing induced by the wave-like traveling heat flux.A resonance is found to form when the phase velocity of the heat-flux perturbation matches the average sound speed in the ablation *** the resonant regime,the coherent density and temperature fluctuations enhance the electron thermal conduction in the ablation region and lead to larger ablation pressure and effective acceleration,which consequently yield higher linear growth rate and saturated bubble *** enhanced effective acceleration offers increased implosion velocity but can also compromise the integrity of inertial confinement fusion shells by causing faster ArTI growth.

The characteristics of plasmas play an important role in femtosecond laser filament-based *** analysis is used to experimentally investigate the plasma density and its temperature of the air filament under different pulse repetition *** our experiments,the measured average plasma density of the filament is 1.54×10^(17)cm^(-3)and the temperature of the plasma is about 5100 K under 100 Hz pulse repetition *** plasma density decreases to1.43×10^(17)cm^(-3)and the temperature increases to 6230 K as the pulse repetition rate increases to 1000 *** experimental observation agrees with the numerical simulation by solving the nonlinear Schr?dinger equations with repetition rate related“low density hole”correction.
