Team harnesses intense X-ray beam, observes unusual phenomenon for the first time

02-Sep-2015

Using an enormous X-ray laser - one of only two such machines on Earth - University of Nebraska-Lincoln physicist Matthias Fuchs and scientists from around the world beat formidable odds to observe one of the most fundamental interactions between X-rays and matter. The findings can aid future ...

Nothing but water: Hydrogen fuel cell unit to provide renewable power to Honolulu port

02-Sep-2015

A new chapter in clean energy is starting in Hawaii. At Young Brothers Ltd.'s Port of Honolulu facility, Sandia National Laboratories is leading the Maritime Hydrogen Fuel Cell project to test a hydrogen-fuel-cell-powered generator as an alternative to conventional diesel generators. The project ...

An engineered surface unsticks sticky water droplets

02-Sep-2015

The leaves of the lotus flower have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to ...

Using ultrathin sheets to discover new class of wrapped shapes

Materials researchers describe a new regime of wrapped shapes

02-Sep-2015

Materials scientists seeking to encapsulate droplets of one fluid within another often use molecules like soap or micro- or nano-particles to do it. One distinct way of wrapping a droplet is to use a thin sheet that calls on capillary action to naturally wrap a droplet in a blanket of film, but ...

Seeing quantum motion

01-Sep-2015

Consider the pendulum of a grandfather clock. If you forget to wind it, you will eventually find the pendulum at rest, unmoving. However, this simple observation is only valid at the level of classical physics. However, quantum mechanics, state that nothing can quite be completely at rest. A team ...

Artificial leaf harnesses sunlight for efficient fuel production

A new solar fuel generation system safely creates fuel from sunlight and water.

01-Sep-2015

Generating and storing renewable energy, such as solar or wind power, is a key barrier to a clean-energy economy. Over the past five years, researchers at Joint Center for Artificial Photosynthesis (JCAP) have made major advances toward this goal, and they now report the development of the first ...

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 ...
