Although solar steam generation strategy is efficient in desalinating seawater,it is still challenging to achieve continuous solar-thermal desalination of seawater and catalytic degradation of organic ***,dynamic regulations of hydrogen bonding networks and solvation structures are realized by designing an asymmetric bilayer membrane consisting of a bacterial cellulose/carbon nanotube/Co_(2)(OH)_(2)CO_(3)nanorod top layer and a bacterial cellulose/Co_(2)(OH)_(2)CO_(3)nanorod(BCH)bottom ***,the hydrogen bonding networks inside the membrane can be tuned by the rich surface–OH groups of the bacterial cellulose and Co_(2)(OH)_(2)CO_(3)as well as the ions and radicals in situ generated during the catalysis ***,both SO_(4)^(2−)and HSO_(5)−can regulate the solvation structure of Na^(+)and be adsorbed more preferentially on the evaporation surface than Cl^(−),thus hindering the de-solvation of the solvated Na^(+)and subsequent nucleation/growth of ***,the heat generated by the solar-thermal energy conversion can accelerate the reaction kinetics and enhance the catalytic degradation *** work provides a flow-bed water purification system with an asymmetric solar-thermal and catalytic membrane for synergistic solar thermal desalination of seawater/brine and catalytic degradation of organic pollutants.

The effect of salt concentration on layer-by-layer deposition of poly（sodium 4-styrene sulfonate）（PSSS）/poly（vinylbenzyl trimethylammonium chloride）（PVTC） was investigated by use of quartz crystal microbalance with dissipation （QCM-D）. The changes in frequency and dissipation demonstrate that the addition of NaC1 leads the thickness of PSSS/PVTC multilayer to increase. The deposition of PSSS/PVTC is dominated by surface charge overcompensation level at lower salt concentrations. However, it is mainly determined by the interpenetration of polyelectrolytes at a higher salt concentration, as reflected in the oscillation of dissipation change.

Millimeter-wave(mm Wave)technique(from around 24 GHz to 300 GHz)becomes a key enabler of high date rates for future mobile communications[1].In spite of many appealing benefits,mm Wave communications also encounter several critical challenges,i.e.,very weak capability in penetration,diffraction and high-order reflections,due to the short wavelength[2].That indicates,the transmission in mm Wave bands can be blocked easily if any obstacle,e.g.,human body or vehicle in motion,occurs on the propagation path.

宇称-时间(PARITY-TIME PT)对称光学波导系统中有关PT对称性的调控主要通过周期性变化的复折射率材料来实现.本文中我们给出了一种对于已耦合的双通道波导体系中额外引入周期调制的中性波导操纵PT对称性的构型,通过高频近似将系统转换为重整化参数后的等效未调制系统后,发现可以通过额外引入单频周期调制的光波导去调控体系的PT对称性,并且讨论了周期调制的非厄米三通道波导体系的能谱特性.最后通过解析和数值的方法给出了光在非厄米三通道光学波导中的动力学演化.
