Scientists at UC Riverside have pushed the current limit of a technique for biologically removing hydrogen sulfide from sewage emissions a step further. Marc Deshusses, associate professor in the department of chemical and environmental engineering, and his postdoctoral researcher, David Gabriel, report in the Proceedings of the National Academy of Sciences (PNAS) that they have modified an existing full-scale chemical scrubber at the Orange County Sanitation District (OCSD), California, to a biological trickling filter.
"Hydrogen sulfide odors, which have the smell of rotten eggs, can be treated in biological reactors called biotrickling filters at rates similar to those observed in chemical scrubbers," said Deshusses. "Biotreatment is cheaper, safer, and more environmentally friendly. In our paper, we also show that you can convert existing chemical scrubbers to biological trickling filters quite easily."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
