Isolation and Characterization of Benzene Degrading Bacteria from Gasoline Contaminated Water
The BTEX (benzene, toluene, ethylbenzene, and xylene)compounds are hydrocarbon pollutants that are considered as significant threat to the health and environment. Among BTEX, benzene is of major concern, because it is soluble, mobile, toxic, carcinogenic [...]
The Need and the Quest for Developing Water Treatment Systems for Masses Which are Low Cost, Low Tech and Use Locally or Easily Available Material
In todays world, a large set of environmental challenges exist. The extent of the environmental damage is alarming and the consequences could be dire. Existence of healthy life requires availability of safe food and clean [...]
12 Billion Dollars Annually Expended on Throw away Filters- There is a new technology alternative to this wasteful practice
In a world that is focussed at finding methods to use less energy or alternatives to existing energy driven products, one obvious change that is essential is the reduced use of disposable products. Specifically this [...]
Effect of surfactant on TiO2/UV mediated heterogeneous photocatalytic degradation of DDT in contaminated water
The toxic effects from the use of pesticides are of great concern to the environment. The pesticides containers are not treated according to the Mexican normativity and hence increase the pollutant levels in the environment, [...]
A Sonoelectrochemical Synthesis of Nanosized CdS on TiO2 Nanotube-Array for Enhancing Photoelectrochemical Reactivity
The nanoparticles of CdS were precipitated onto a self-organized TiO2 nanotube array photo-electrodes by using sonochemical synthesis combining with constant current electrochemical deposition. It is indicated that the CdS nanoparticles with average diameter of 28.1 [...]
Use of different natural Extracts from Tropical plants as Green Inhibitors for Metals
The authors present an overview of the work & results obtained in the framework of a bilateral cooperation program between Belgium and Vietnam to discover new environmentally-friendly corrosion inhibitors or ‘harmless corrosion inhibitors to nature” [...]
Degradation of Phenol in Waste Water Using Alcohol-Free Enzyme Encapsulated Silica Aerogel
Encapsulation of enzyme tyrosinase into nano-porous silica aerogel via an alcohol-free colloidal sol-gel route using rice husk ash (RHA) as silica source was studied. Tyrosinase encapsulated silica aerogel (TESA) was synthesized with and without solvent [...]
Removal of Heavy Metals From Aqueous Solutions with Calcium Alginate Beads
The present research is focused on the development of a bio-sorbent based on alginate beads. The alginate is a natural polymer extracted from brown seaweed with capability of hosting divalent cations in gel state, which [...]
A Nanotechnology Policy Framework for California
We are in the process of writing a nanotechnology framework policy recommendation for the state of California. It will be the first report of its kind to incorporate scientific analysis with regulatory recommendations. It will [...]
