There were 20 million metric tons of lead bullets fired in the United States in the 20th century. Is that lead having an environmental impact? Not at or near the U.S. Forest Service firing range near Blacksburg, Va., according to research by Virginia Tech geological scientists. Donald Rimstidt, a professor in the Department of Geosciences, College of Science at Virginia Tech will report the conclusions of a five-year study at the 116th national meeting of the Geological Sciences of America in Denver Nov. 7-10.
There are 9,000 nonmilitary shooting ranges and a lot of military ones in the United States. Some 60,000 metric tons of lead are expended by shooting. (a metric ton or "long ton" is 2,200 lbs.). "So there is lead shot and bullets everywhere," Rimstidt said. "We were invited by the U.S. Forest Service to look at the shooting range in the National Forest near Blacksburg."
The researchers’ survey found 11 metric tons of shot in the shotgun range and 12 metric tons of lead bullets in the rifle range. "These ranges are 10 years old. Most of the lead shot has accumulated on about four or five acres. Some shots have been into the woods, which cover hundreds of acres," Rimstidt said.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
