The rapidly increasing global demand for energy combined with the environmental impact of fossil fuels has spurred the search for alternative sources of clean energy. One promising approach is to convert solar energy into hydrogen fuel using photoelectrochemical cells. However, the semiconducting photoelectrodes used in these cells typically have low(More)
Reduction in surface and interface reflectance via the integration of subwavelength nanostructures in flexible polymer packaging material combined with incorporation of dielectric nanoislands into a conventional two-layer antireflection coating has been demonstrated, analyzed and optimized. Transmittance measurements of moth-eye textured polymer packaging(More)
We designed and evaluated a kind of Agkistrodon DNA detection kit. Bioinformatics was used to investigate the characteristics of cytochrome b (cyt b) gene in Agkistrodon. A series of primers were designed, and sequencing and blasting in conjunction with PCR technology were applied. Its' indexes including specificity, sensitivity and repeatability were(More)
We demonstrate the integration of subwavelength moth-eye and Al 2 O 3 nanoisland structures fabricated on polymer packaging sheets and the surface of conventional Al 2 O 3 /TiO 2 bilayer antireflection coatings, respectively, with epitaxial lift-off single-junction GaAs solar cells. The mechanically flexible cell structure with the integrated optical(More)
Response of 12 urban lakes with different trophic states in Beijing to variations of meteorological factors was studied in this research. Monthly water quality parameters, including total nitrogen (TN), total phosphorus (TP), chlorophyll a, chemical oxygen demand (COD), biological oxygen demand (BOD), dissolved oxygen, and water temperature, were analyzed(More)
