Solar photocatalytic degradation of azo dye Reactive Black 5 in aqueous suspension of TiO2
Photocatalytic degradation of pollutants under solar light irradiation is an economically viable process and a very promising clean wastewater treatment technology. The aim of this study is to evaluate photocatalytic degradation of Reactive Black 5 (RB5) under natural sunlight irradiation with TiO2 as photocatalyst. The effects of initial concentration of RB5, dosage of TiO2, with/without solar ...

Aid, economic growth and environmental sustainability: rich-poor interactions and environmental choices in developing countries
Rich-poor interactions complicate the search for a stable Environmental Kuznets Curve (an "inverted U" relationship between income per-capita and environmental degradation). We show that aid from richer to poorer countries to support investments in environment, in either of two forms, alters the income-environment relationships that otherwise exist, lowering levels of degradation in the poorer ...

Legal Lookout: Nanotechnology: EPA Considers How to Proceed
Untitled Document Nanotechnology is broadly defined to include technologies involving the control of materials and structures with nanoscale dimensions of 1 to 100 nanometers. Because the ratio of surface to total atoms increases exponentially with decreasing particle size, nanosized particles have uniquely large surface areas that offer special and very desirable ...
