Achieving Solar-Thermal-Electro Integration Evaporator Nine-Grid Array with Asymmetric Strategy for Simultaneous Harvesting Clean Water and Electricity.

Water evaporation is a ubiquitous and spontaneous phase transition process. The utilization of solar-driven interface water evaporation that simultaneously obtains clean water and power generation can effectively alleviate people's concerns about fresh water and energy shortages. However, it remains a great challenge to efficiently integrate the required functions into the same device to reduce the complexity of the system and alleviate its dependence on solar energy to achieve full-time operation.

A new caffeic acid tetramer from the Dracocephalum moldavica L.

A new caffeic acid tetramer compound, named (+) methyl rabdosiin (4), together with seven known caffeic acid multimers (1-3, 5-8) and one caffeic acid monomer (9), were isolated from the aerial parts of Dracocephalum moldavica L. The structures of these compounds were assigned on the basis of 1D and 2D NMR spectroscopic and mass spectrometry analyses. The protective effects of compounds 2-4 against hydrogen peroxide (HO)-induced apoptosis were evaluated in primary cardiomyocytes of SD neonatal rats in vitro by the MTT method.

8.4mJ, 10kHz, 3.6ns, Nd:YVO slab amplifier.

A diode-pumped nanosecond eight-pass amplifier with Nd:YVO crystal was developed. Combined with the advantages of direct pumped and Innoslab structure, a high energy pulse was obtained by using the wedged multi-folded configuration with two plane mirrors. The 0.

Study of the inflammatory response of immunocytes to polymerized porcine hemoglobin (pPolyHb).

Polymerized porcine hemoglobin (pPolyHb), which was synthesized from chemically modified porcine hemoglobin, can carry and deliver oxygen to tissues in addition to restoring intravascular volume. Assessment of the inflammatory response generated in the host is a part of the overall safety evaluation of pPolyHb. In this study, we measured the levels of IL-1β, IL-10, and CD11b/CD18 in response to pPolyHb stimulation, both in vivo (in rats) and in vitro.

The application of polymerized porcine hemoglobin (pPolyHb) in the rat small bowel preservation.

Small bowel transplantation (SBTx) has become a standard clinical treatment for short bowel syndrome or irreversible intestinal function failure. Optimum preservation of the organ is essential for the success of transplantation. In this study, pPolyHb was used as an additive to hypertonic citrate adenine solution (HCA) to provide oxygen for rat small bowel transplant.

Study of the distributed thermal lens of LD end pumped rectangular gain.

In the LD end pumped rectangular laser gain medium, the thermal induced refractive index is not only non-uniformly transversely, but also non-uniformly and distributed along the pumping beam propagation, the effect of thermal lens is a distributed not a lumped lens effect as previously considered. In this paper, the effect of a distributed thermal lens is analyzed.

Study of the influence of the slope interfaces upon the image quality of liquid optical lens.

The solid interface of different slopes plays a significant role in influencing focus range and image quality of liquid controllable optical lens. In this paper, based on the theoretical model of liquid optical lens, the spherical aberration of the liquid optical lens is calculated. It is found that the spherical aberration is different from the two opposite sides of liquid optical lens, and at the same voltage range, the smaller the cone angle of the solid interface is, the larger the optical aperture of liquid optical lens changes.
