Are we rushing to embrace the potential benefits of nanotechnology without considering the...

We talk a lot about the wonders of nanotechnology here at Gizmag. After all it’s easy to get caught up in the excitement surround the technology when it promises to revolutionize practically every area of human endeavor. Among its long list of anticipated benefits are new medical treatments; stronger, lighter materials; improved energy production, storage and transmission; and more effective pollution monitoring and prevention, just to name a few. But nanotechnology is not just something set to come about in some far off future – it is happening now. In fact, the odds are there is a product either containing, or made using nanoparticles sitting in your house right now. But the big question is, are they safe?  Read More

An all too common sight - the car park oil sheen rainbow (Photo: crabchick via flickr)

The rainbow effect caused by varying thicknesses of oil film on water’s surface might be pretty to look at but is indicative of polluted water. This “oil sheen” proves especially difficult to remove, even when the water is aerated with ozone or filtered through sand. But now a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters.  Read More

Penn State researchers, Bruce Logan, and Maha Mehanna, with the three-chambered microbial ...

Desalination plants generally employ one of two methods to produce clean water – reverse osmosis or electrodialysis. Unfortunately, both processes require large amounts of energy, but an international team of researchers has proven a process that cleans wastewater can also remove 90 percent of salt from brackish water or seawater while generating electricity.  Read More

Portable, self-sustaining technology can transform wastewater to EPA standards within 24-4...

In disasters such as hurricane Katrina, dealing with wastewater can be one of the greatest difficulties facing military and relief operations. Nicknamed “DAAB” (Deployable Aqueous Aerobic Bioreactor), this new self-sustaining, portable, and “smart” wastewater treatment system offers a solution to this critical problem.  Read More

Microbial fuel cell promises high yield hydrogen source and wastewater cleaner

April 29, 2005 The hydrogen economy is looming, and it seems a weekly occurance to see additional announcements of technology adding to the momentum. This week from Penn State University comes the news of an electrically-assisted microbial fuel cell (MFC) that does not require oxygen and uses bacteria to coax four times as much hydrogen directly out of biomass than can be generated typically by fermentation alone.  Read More
