comaring the capability of photocatalyst nano zinc oxide process by two slurry and immobilized methods in dye acid orange 7 removal introduction everyday million liters of color wastewater are produced in different industries and cuases environmental problems. the textile industry significantly affects the environment, producing high volume of wastewater from water and chemicals used in process...

Enhancing the photocatalytic performance for contaminant degradation to accelerate large-scale application of photocatalysis still is an enduring challenge. Herein, ternary PDI/BiOCl-BiPO4 composited materials with different contents PDI were designed and constructed by multi-step compound method. The tetracycline hydrochloride rhodamine B chosen as targeted pollutants investigate materials. st...

We have begun a compilation of H i maps of peculiar galaxies kindly contributed by individual investigators, many as part of the “Gas & Galaxy Evolution” conference. In this gallery we present images of the first ∼180 objects, which includes over 400 individually cataloged galaxies. The images consist of a greyscale representation of the optical morphology and an accompanying optical image with...

Photoalignment possesses obvious advantages in comparison with the usually “rubbing” treatment of the substrates of liquid crystal display (LCD) cells. The liquid crystal photoalignment is nano-technology, as the thickness of the alignment layer is about 2-15 nm. The application of the photo-alignment and photo-patterning nano technology for the new generation of photonic and display devices wi...

With digital still cameras, users can easily collect thousands of photos. Our goal is to make organizing and browsing photos simple and quick, while retaining scalability to large collections. To that end, we created a photo management application concentrating on areas that improve the overall experience without neglecting the mundane components of such an application. Our application automati...

This review focuses on exploring the defect active sites by determining location and type semi-quantitative calculation of concentrations a variety representational methods.
