With the rapid development of Internet, information on Internet presents an explosive growth. Cloud computing and big data analysis technology based rise accordingly. However, all web pages contain not only important but also noise irrelevant to subject information. They seriously affect accuracy extraction, so research page extraction arises at historic moment becomes hotspot. The quality text...

Highly-ordered TiO2 nanotubes (NTs) have gained much importance for application in hydrogen production by water splitting (photoelectrochemical cells) and the dye-sensitized solar cells (DSCs) [1,2]. The TiO2 NTs can be synthesized using a titanium foil in fluoride containing electrolytes via electrochemical anodization method. The NTs geometry depends on different anodizing parameters (electro...

Zeolitic imidazolate framework (ZIF-8) nanocrystals were uniformly grown on the surface of cellulose (CNCs) to give a hybrid material, [email protected] By varying stoichiometry components, it was possible control size ZIF-8 crystals CNC surface. Optimized ([email protected]) used as template synthesize microporous organic polymer (MOP), protected]@CNC. After etching with 6 M HCl solution, MOP ...

We report for the first time direct growth of quantum dot (QD) lasers with electrical pumping on 300 mm Si wafers both a planar template and in-pocket in-plane photonic integration. O-band five QD layers were grown molecular beam epitaxy (MBE) in reactor then fabricated into standard Fabry–Perot ridge waveguide cavities. Edge-emitting are demonstrated high yield reliable results ready commercia...

Dye sensitized solar cell was fabricated from a double layer photoanode. First, TiO2 nanoparticles  were synthesized by hydrothermal method. These TiO2 NPs were deposited on FTO glasses by electrophoretic deposition  method in applied voltage of 5 V and EPD time of 2.5-10 min. Then TiO2 hollow spheres (HSs) were synthesized by sacrificed template method with Carbon Spheres as template and TTIP ...
