Waste paper could make summer grilling more environmentally friendly

28-Aug-2015

Summertime is waning, and that means the end of backyard barbecues is almost upon us. That also means an end to dousing charcoal briquettes with lighter fluid. Reducing the use of lighter fluid might not be a bad thing, as many of those products are made from crude oil and emit potentially ...

Antimatter catches a wave at SLAC

(DOE/SLAC National Accelerator Laboratory) A study led by researchers from the US Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los Angeles has d

28-Aug-2015

A study led by researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and the University of California, Los Angeles has demonstrated a new, efficient way to accelerate positrons, the antimatter opposites of electrons. The method may help boost the energy and ...

Electrospray solves longstanding problem in Langmuir-Blodgett assembly

25-Aug-2015

In the 1930s, Irving Langmuir and Katharine Blodgett discovered that by spreading molecules with volatile organic solvents on the surface of water, they could create a one-molecule-thick film and use it as an anti-reflective coating for glass. Later named Langmuir-Blodgett assembly, this ...

Graphene oxide's secret properties revealed at atomic level

A research team found that graphene oxide's inherent defects give rise to a surprising mechanical property

25-Aug-2015

Since its discovery, graphene has captured the attention of scientists and engineers for its many extraordinary properties. But graphene oxide largely has been viewed as graphene's inferior cousin. "Graphene is so perfect," said Northwestern Engineering's Jiaxing Huang. "And graphene oxide is ...

Physicist tests theories of dark energy by mimicking the vacuum of space

24-Aug-2015

Ever since dark energy was discovered in 1998, scientists have been proposing theories to explain it - one is that dark energy produces a force that can be measured only where space has a very low density, like the regions between galaxies. Paul Hamilton, a UCLA assistant professor of physics and ...
