Experimental Ebola treatment boosts survival in mice

May 21, 2015 8:25 am | by American Chemical Society | News | Comments

The number of new Ebola cases is tapering off, but the search for new treatments continues. Now, one research team has found potential drug candidates that successfully treated up to 90% of mice exposed to the Ebola virus. They report their findings in ACS Infectious Diseases.

Shape-shifting plastic

May 21, 2015 8:18 am | by Morgan McCorkle, Oak Ridge National Laboratory | Videos | Comments

Not all plastics are created equal. Malleable thermoplastics can be easily melted and reused in products such as food containers. Other plastics, called thermosets, are essentially stuck in their final form because of cross-linking chemical bonds that give them their strength for applications such as golf balls and car tires.

Defects can “Hulk-up” materials

May 21, 2015 8:09 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

In the story of the Marvel Universe superhero known as the Hulk, exposure to gamma radiation transforms scientist Bruce Banner into a far more powerful version of himself. In a study at Lawrence Berkeley National Laboratory, exposure to alpha-particle radiation has been shown to transform certain thermoelectric materials into far more powerful versions of themselves.

American energy use up slightly

May 21, 2015 8:00 am | by Anne M. Stark, Lawrence Livermore National Laboratory | News | Comments

Americans' energy use continued to grow slowly in 2014, fueled by increases in the use of natural gas, wind and solar, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory (LLNL). Each year, the LLNL releases charts that illustrate the nation's consumption and use of energy. Overall, Americans used 0.9 quads BTUs more in 2014 than the previous year, an increase of about 1%.

Astronomers observe supernova colliding with its companion star

May 21, 2015 7:51 am | by Allie Akmal, Caltech | News | Comments

Type Ia supernovae, one of the most dazzling phenomena in the universe, are produced when small dense stars called white dwarfs explode with ferocious intensity. At their peak, these supernovae can outshine an entire galaxy. Although thousands of supernovae of this kind were found in the last decades, the process by which a white dwarf becomes one has been unclear.

How to make continuous rolls of graphene

May 21, 2015 7:30 am | by David L. Chandler, MIT News Office | News | Comments

Graphene is a material with a host of potential applications, including in flexible light sources, solar panels that could be integrated into windows and membranes to desalinate and purify water. But all these possible uses face the same big hurdle: the need for a scalable and cost-effective method for continuous manufacturing of graphene films.

Students apply physics to football at the Emirates Stadium

May 20, 2015 12:13 pm | by IOP | News | Comments

Students from four schools took part in a day of physics and football at Arsenal’s Emirates Stadium on May 15, 2015, as the finale of an eight-week program to engage students with science by applying it to soccer. The schools have been running after-school physics and football clubs in which students learnt about such concepts as projectiles, impact area and center of mass and applied their knowledge in practice on the football pitch.

New printing process makes three-dimensional objects glow

May 20, 2015 12:00 pm | by Karlsruhe Institute of Technology | News | Comments

Conventional electroluminescent (EL) foils can be bent up to a certain degree only and can be applied easily onto flat surfaces. The new process allows for the direct printing of electroluminescent layers onto three-dimensional components. Such EL components might be used to enhance safety in buildings in case of power failures. Other potential applications are displays and watches or the creative design of rooms.

Amazing microdroplet structures may lead to new technologies

May 20, 2015 11:47 am | by IPC PAS | News | Comments

A team of researchers has unveiled a new method of controlling the shapes of structures—so called mesoatoms—formed by microdroplets placed inside another drop. The work increases the possibilities of controlling the processes of self-organization of matter. During their research, the scientists also managed for the first time to observe the formation of microdroplet structures with unexpected shapes.

Tiny grains of lithium dramatically improve performance of fusion plasma

May 20, 2015 11:37 am | by DOE/Princeton Plasma Physics Laboratory | News | Comments

Scientists have discovered a phenomenon that helps them to improve fusion plasmas, a finding that may quicken the development of fusion energy. They found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically. High heat and pressure are crucial to fusion...

Measuring thermoelectric behavior by “Tinkertoy” materials

May 20, 2015 10:42 am | by Sandia National Laboratories | News | Comments

Sandia National Laboratories researchers have made the first measurements of thermoelectric behavior by a nanoporous metal-organic framework (MOF), a development that could lead to an entirely new class of materials for such applications as cooling computer chips and cameras and energy harvesting. This work builds on previous research in which the Sandia team realized electrical conductivity in MOFs by infiltrating the pores with TCNQ.

Non-metallic mesoporous structures have already demonstrated potential for applications in gas storage, separation, catalysis, ion-exchange, sensing, polymerization and drug delivery. Metal mesoporous films could have fascinating and useful optical properties, as they are effectively the inverse of nanoparticle arrays. Researchers have demonstrated a simple approach for producing metal films with regular tuneable mesopores.

Natural gas versus diesel

May 20, 2015 8:24 am | by American Chemical Society | News | Comments

Some major trucking companies are turning to natural gas to fuel their fleets, and to earn “green” credit among customers. But celebrating lower emissions could be premature. Researchers have found that converting heavy-duty trucks to run on natural gas could lead to negative climate impacts if steps are not taken to improve engine efficiency and reduce methane emissions from the fuel’s supply chain.
