| Buckyballs enhance carbon capture Posted: 03 Dec 2014 02:18 PM PST Amines bound by buckyballs can absorb carbon dioxide from emissions at industrial plants and at natural gas wells, according to new research. Tests from one to 50 atmospheric pressures showed the newly developed compound captured a fifth of its weight in carbon dioxide but no measurable amount of methane. |
| More Hispanics earning bachelor’s degrees in physical sciences and engineering Posted: 03 Dec 2014 08:07 AM PST The number of Hispanic students receiving bachelor's degrees in the physical sciences and engineering has increased over the last decade or so, passing 10,000 degrees per year for the first time in 2012. The overall number of U.S. students receiving degrees in those fields also increased over the same time, but it increased faster among Hispanics. |
| Green meets Nano: Scientists create multifunctional nanotubes using nontoxic materials Posted: 03 Dec 2014 07:01 AM PST A doctoral student in materials science is making multifunctional nanotubes of gold – with the help of vitamin C and other harmless substances. |
| Posted: 03 Dec 2014 07:01 AM PST Polylactic acid is a degradable plastic used mostly for packaging. To meet the rising demand, researchers have developed an eco-friendly process to make large amounts of lactic acid from glycerol, a waste by-product in the production of biodiesel. |
| Computer model enables design of complex DNA shapes Posted: 03 Dec 2014 05:40 AM PST Biological engineers have created a new computer model that allows them to design the most complex three-dimensional DNA shapes ever produced, including rings, bowls, and geometric structures such as icosahedrons that resemble viral particles. |
| Increased production not the way to grow the economy Posted: 03 Dec 2014 05:39 AM PST Continued economic growth requires an alarming – and arguably unsustainable – amount of raw material and energy. But what if there was a way to rein in production, without slowing down the economy? |
| Smart anti-icing system for rotor blades Posted: 03 Dec 2014 05:38 AM PST In very cold climate zones, the wind can blow with tremendous force. But wind turbines have rarely been built in these regions up to now. The risk of ice formation on the rotor blades is just too high. But now, an energy-efficient heating system frees these turbines from the ice in a matter of seconds. It is only switched on when water freezes. |
| Posted: 03 Dec 2014 05:37 AM PST With good planning, it is possible to promote the reuse of construction and demolition waste and thereby both conserve the environment and save on material costs. In the future, it will be even more important to assess how buildings can reasonably be repaired or demolished into parts, together with how the remaining service life of the parts can be utilized in new applications. The best method is to implement demolition planning already as a component of construction design. |
