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.

We measure the dispersed spectrum of the A2H-X2E＋ system of MgH using laser abla- tion/laser induced Fluorescence method and obtain the Frank-Condon factors and related transition frequencies of the A2H（v＇=0）-X2∑＋（v＂=0,1） system by analyzing the experimental spectrum. Also, we calculate the Franck-Condon factors and transition frequencies of the A2H-X2∑＋ system of MgH. A comparison of our theoretical calculation and experimental results with other reported theoretical results was carried out as well.

As the epitome of the modern regenerative medicine, stem cells were proposed in the basic sense no more than 200 years ago. However, the concept of "stem cells" existed long before the modern medical description. The hypothesis that all things, including our sentient body, were generated from a small origin was shared between Western and Chinese people. The ancient Chinese philosophers considered Jing(also known as essence) as the origin of life. In Chinese medicine(CM), Jing is mainly stored in Kidney(Shen) and the so-called Shen-Jing(Kidney essence). Here, we propose that Shen-Jing is the CM term used to express the meaning of "origin and regeneration". This theoretical discovery has at least two applications. First, the actions underlying causing Shen-Jing deficiency, such as excess sexual intercourse, chronic diseases, and aging, might damage the function of stem cells. Second, a large number of Chinese herbs with Shen-Jing-nourishing efficacy had been proven to affect stem cell proliferation and differentiation. Therefore, if Shen-Jing in CM is equivalent with stem cells in regenerative medicine, higher effective modulators for regulating stem-cell behaviors from Kidney-tonifying herbs would be expected.
