Coupling experiments to theory to build a better battery

Researchers has reported that a new lithium-sulfur battery component allows a doubling in capacity compared to a conventional lithium-sulfur battery, even after more than 100 charge cycles.

Building blocks to create metamaterials

Engineers have created a method to systematically design metamaterials using principles of quantum mechanics.

Using electricity to switch magnetism

Scientists have managed to use electrical fields to control the magnetic oscillations of certain ferrous materials. This has opened up huge potential for computer technology applications, as data is currently transferred in the form of electrical signals but stored magnetically.

Long-lived physics

New particles produced in the LHC's high-energy proton-proton collisions don't hang around for long. A Higgs boson exists for less than a thousandth of a billionth of a billionth of a second before decaying into lighter particles, which can then be tracked or stopped in our detectors. Nothing rules out the existence of much longer-lived particles though, and certain theoretical scenarios predict that such extraordinary objects could get trapped in the LHC detectors, sitting there quietly for days.

Semiconductor breakthrough may be game-changer for organic solar cells

In an advance that could push cheap, ubiquitous solar power closer to reality, researchers have found a way to coax electrons to travel much further than was previously thought possible in the materials often used for organic solar cells and other organic semiconductors.

Political corruption scandals may be predicted by network science

According to the World Bank, corruption scandals siphon more than $2 trillion per year from the global economy, making corruption one of the major causes of slow economic growth and socioeconomic inequality. Now in a new study, researchers have demonstrated that it may be possible to predict who will play a role in future scandals by modeling current scandals using networks. The results may provide a tool for detecting corruptive practices and reducing the high cost of corruption to society.

Physicists succeed in measuring mechanical properties of 2-D monolayer materials

Physicists have for the first time succeeded in characterizing the mechanical properties of free-standing single-atom-thick membranes of graphene.

Ultra-thin optical fibers offer new way to 3-D print microstructures

For the first time, researchers have shown that an optical fiber as thin as a human hair can be used to create microscopic structures with laser-based 3-D printing. The innovative approach might one day be used with an endoscope to fabricate tiny biocompatible structures directly into tissue inside the body.

Using electricity to switch magnetism

At TU Wien, researchers have taken a major step toward linking electrical and magnetic material properties, which is crucial for possible applications in electronics.

Future electronics may ride on new three-in-one particle

"Trion" may sound like the name of one of the theoretical particles blamed for mucking up operations aboard the Starship Enterprise.
