Laboratory researchers are helping companies characterize materials and test components as part of the industry's preparation for the new emissions mandates. The requirements will result in a 90 percent reduction in nitrogen oxide, or NOX, and particulate matter, or soot, released by diesel vehicles, from semi-trucks to cars.
At HTML, commercial users have put to use the center's state-of-the-art instruments that analyze products for durability, resistance to heat and stress, thermal conductivity, mechanical behavior and other properties.
"Environmental Protection Agency regulations are pushing emissions control technology very hard, so that engine and emissions control equipment manufacturers require access to very sophisticated tools to develop this technology. Fortunately, our user facilities are well equipped to help them," said Arvid Pasto, director of the HTML.
Diesel engine-maker Cummins used HTML's x-ray diffraction, raman spectroscopy and electron microscopy capabilities to better understand the properties of materials used in exhaust after-treatment systems. In addition to studying how catalysts can be adversely affected by sulfur and other gaseous exhaust components, Cummins and HTML worked together to characterize the fatigue life of cordierite diesel soot filters, which remove more than 98% of particulate emissions from diesel exhaust. These exhaust after-treatment devices are critical to meeting upcoming emissions requirements.
"Cummins utilizes HTML's world class capabilities in materials characterization as well as the research knowledge the HTML staff has obtained from working on diverse engineering challenges. HTML's efforts are matched by Cummins research and development resources, resulting in environmentally friendly production diesel engines that meet regulatory requirements while achieving state-of-the-art fuel efficiency and decreasing our oil dependence," said Roger England, Catalyst Elements Leader for Cummins, Inc.
In another project for Industrial Ceramic Solutions, based in Knoxville, Tenn., HTML used its scanning electron microscope to analyze material the start-up company was using to make ceramic-fiber diesel particulate exhaust filters. The original material did not function as well as competing products and had a tendency to crack. The tests connected the trouble to the fabrication process, and the company made changes that improved product performance.
"The sophisticated electron microscopy at HTML allowed our small business to literally look inside of the ceramic fiber filter media at thousands of times magnification," said Richard Nixdorf, ICS president and CEO. "This information led ICS to solutions that eliminated micro-cracking and moved our filter-media strength far beyond what the diesel exhaust filter application demanded." ORNL is managed by UT-Battelle for the Department of Energy.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
