An indium tin oxide (ITO) electrode modified with monolayer clay/[Ru(phen)2(dC18bpy)]2+ (phen= 1,10-phenanthroline, dC18bpy = 4,4′-dioctadecyl-2,2′ bipyridyl) hybrid film has been fabricated by the Langmuir-Blodgett (LB) method. Atomic force microscopy revealed that the single-layered hybrid film of clay/[Ru(phen)2(dC18bpy)]2+ (denoted as Clay-Ru) was closely packed at a surface pressure of 25 mN-m-1 and had a thickness of 3.4±0.5 nm. Cyclic voltammograms showed that the redox current of Ru(Ⅱ) complex decreased when incorporated into the clay film, suggesting that the clay layer acts as a barrier against electron transfer. When applied to oxidizing the mononucleotide of guanosine 5′-monophosphate (GMP), a large catalytic oxidative current was achieved on the Clay-Ru(Ⅱ) modified ITO electrode at the external potential above 900 mV (vs. Ag|AgCl|KCl ) and, more significantly, this response was further enhanced by light irradiation (λ>360 nm), in which the photocurrent is increased about 11 times in comparison with that of a bare ITO. Mechanism of the photoelectrocatalytic effect was proposed in terms of the reduction of the photoelectrochemically generated Ru(Ⅲ) complex in the Clay-Ru film by GMP.

The use of laser energy to weld biological tissues and produce sutureless anastomosis has its advantages over conventional silk-sutured anastomosis since it was reported in small vessels[1] and fallopian tubes[2], in the late 1970s. Since then, more investigators have welded a larger variety of tissues[3-13] and have expanded its application to welding trials of entertomies of rabbit and rat small intestine[14-17] Sauer et al[18] reported results from Nd: YAG laser in reconstruction of end-to-end welding in rabbit small intestine. Recently, controlled temperature during YAG and argon laser-assisted welding of entertomies of rabbit and rat was implemented to eliminate exponential increases in the rate of denaturation associated with rapidly increasing temperature[19，20]. Yet there was no report of sutureless end-to-end bowel anastomosis using low-power CO2 laser. This is a report of a circumferential end-to-end laser welding bowel anastomosis in rabbit by using 3 different CO2 laser powers to explore the feasibility of CO2 laser welding of a circumferential intestinal tissue and to determine the optimal laser-welding parameter. Then the appropriate CO2 laser power was chosen to weld bowels in rabbit and its long-term healing effect was evaluated.

Due to large topography slopes in natural rivers, pollutant concentration embodies a property of three-dimensional distribution when wastewater is discharged from effluents along the bank. With the sigma coordinate along the vertical dimension fitted to both the moving free surface and the bed topography, a three-dimensional numerical model was developed in the present work to address pollutant transport processes in the above-mentioned cases. To avoid the reduction in accuracy caused by spurious diffusion in the case of steep bottom slopes, a formula for horizontal diffusion in the sigma coordinate system was derived. A case study for the side discharge into a straight open-channel flow shows that numerical results are verified well by experimental data. Furthermore, the present model is also verified by the simulation of discharging wastewater from Fuling Phosphorus Factory effluent into the Three Gorges Reservoir and the agreement between the numerical simulation results and field observation data is satisfactory. The change of the mixing zone scope in the water surface versus the layers along the vertical dimension was also discussed in detail. The study shows that a more realistic calculation for pollutant discharge has been provided by the present model than by the depth-average model which predicts an unrealistically smaller mixing zone.
