A novel composite material has been developed by scientists in the Energy Safety Research Institute (ESRI) at Swansea University which shows promise as a catalyst for the degradation of environmentally-harmful synthetic dye pollutants, which are released at a rate of nearly 300,000 tonnes a year into the world’s water. This novel, non-hazardous photocatalytic material effectively removes dye pollutants from water, adsorbing more than 90 % of the dye and enhancing the rate of dye breakdown by almost ten times using visible light. The researchers, led by Dr. Charles W. Dunnill and Dr. Daniel Jones at the Energy Safety Research Institute in Swansea University, reported theirRead More →

Since teaching scientific methods and illustrating how science exists in the “real world” you often take your science classes on field trips. The problem or challenge you may face is that one or more of the field trip locations may be out of your geographical reach. With such advancements in technology, this does not preclude a field trip as a learning option. It simply requires you to take a virtual field trip instead. Types From webinars, teleseminars and a myriad of other options, you can virtually transport your students from the classroom to the location. From black hole and geological exploration to the ecosystem ofRead More →

Taking inspiration from an unusual source, a Sandia National Laboratories team has dramatically improved the science of scintillators — objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials through America’s ports and borders. The Sandia Labs team developed a scintillator made of an organic glass which is more effective than the best-known nuclear threat detection material while being much easier and cheaper to produce. Organic glass is a carbon-based material that can be melted and does not become cloudy or crystallize upon cooling. Successful results of the Defense Nuclear Nonproliferation projectRead More →

For surfers, finding the “sweet spot,” the most powerful part of the wave, is part of the thrill and the challenge. Scripps Institution of Oceanography at the University of California postdoctoral researcher Nick Pizzo has found the exact location on the wave where a surfer gains the greatest speed to get the best ride. Published this month online in the Journal of Fluid Mechanics, Pizzo applied principles of physics at the ocean’s surface—where air and water meet—to study how energy is transferred from the underlying wave to a particle on the surface, in this case, a surfer. “Based upon the speed and geometry of theRead More →
