Recent studies conducted at Marshall University have demonstrated that nanoparticles of cerium oxide–common diesel fuel additives used to increase the fuel efficiency of automobile engines–can travel from the lungs to the liver and that this process is associated with liver damage. The data in the study by Dr. Eric R. Blough and his colleagues at Marshall´s Center for Diagnostic Nanosystems indicate there is a dose-dependent increase in the concentration of cerium in the...

By Kathy Svitil, California Institute of Technology Using a common metal most famously found in self-cleaning ovens, Sossina Haile hopes to change our energy future. The metal is cerium oxide"”or ceria"”and it is the centerpiece of a promising new technology developed by Haile and her colleagues that concentrates solar energy and uses it to efficiently convert carbon dioxide and water into fuels. Solar energy has long been touted as the solution to our energy woes, but while it is...

A team of American and Swiss researchers have reportedly developed a unique device that can harness the Sun's energy and turn it into fuel. The prototype mechanism, which was the subject of an article by BBC News Science Reporter Neil Bowdler on Thursday, captures the Sun's rays and concentrates it with a quartz window, focusing it onto a metal oxide known as cerium oxide, or ceria. Ceria tends to exhale oxygen when it gets hot and inhale it as it cools, and in the device, that property is...

Measuring a fuel cell's overall performance is relatively easy, but measuring its components individually as they work together is a challenge. That's because one of the best experimental techniques for investigating the details of an electrochemical device while it's operating is x-ray photoelectron spectroscopy (XPS). Traditional XPS works only in a vacuum, while fuel cells need gases under pressure to function. Now a team of scientists from the University of Maryland, the U.S. Department...

Engineering researchers from Tufts University, the University of Wisconsin-Madison and Harvard University have demonstrated the low-temperature efficacy of an atomically dispersed platinum catalyst, which could be suitable for on-board hydrogen production in fuel-cell-powered vehicles of the future. An alternative to copper, which under certain conditions can ignite spontaneously, the platinum-based catalyst is highly active and stable. The researchers' understanding of the structure and...

Sudipta Seal is enthralled by nanoparticles, particularly those of a rare earth metal called cerium. The particles are showing potential for a wide range of applications, from medicine to energy.Seal is a professor of materials science and engineering at the University of Central Florida (UCF), and several years ago, he and his colleagues engineered nanoparticles of cerium oxide (CeO2), a material long used in ceramics, catalysts, and fuel cells. The novel nanocrystalline form is non-toxic...
