Evidence suggests subatomic particles could defy the standard model

Large Hadron Collider team finds hints of leptons acting out against time-tested predictions

31-Aug-2015

The Standard Model of particle physics, which explains most of the known behaviors and interactions of fundamental subatomic particles, has held up remarkably well over several decades. This far-reaching theory does have a few shortcomings, however - most notably that it doesn't account for ...

Turning alcohols into alkylating agents

Taking a cue from nature

31-Aug-2015

Researchers at Princeton have developed a dual catalyst system that directly installs alkyl groups onto heteroarenes. The new reaction uses simple and abundant alcohols and offers a milder and more widely applicable alternative to existing strategies. The reported transformation is the first to ...

Soaking up carbon dioxide and turning it into valuable products

Berkeley Lab researchers double down on a good thing by incorporating catalysts into crystalline sponges

31-Aug-2015

A molecular system for the capture and storage of carbon dioxide has been modified so that it now also holds great promise as a catalyst for converting captured carbon dioxide into valuable chemical products. Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory ...

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 ...

Researchers combine disciplines, computational programs to determine atomic structure

27-Aug-2015

A team from the University of Illinois at Urbana-Champaign and Indiana University combined two techniques to determine the structure of cyanostar, a new abiological molecule that captures unwanted negative ions in solutions. When Semin Lee, a chemist and Beckman Institute postdoctoral fellow at ...

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 ...
