Excitons pave the way to higher-performance electronics

After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices.

Molecular switch detects metals in the environment

An international team led by researchers from the University of Geneva (UNIGE), Switzerland, has designed a family of molecules capable of binding to metal ions present in the surrounding environment and providing an easily ...

Kirigami-inspired technique manipulates light at the nanoscale

Nanokirigami has taken off as a field of research in the last few years; the approach is based on the ancient arts of origami (making 3-D shapes by folding paper) and kirigami (which allows cutting as well as folding) but ...

Polarized light—a simple route to highly chiral materials

Researchers at the University of Tokyo used an efficient method to create chiral materials using circularly polarized light. Depending on whether left- or right-polarized, the light source induced electric fields at opposite ...

Quantum shift shows itself in coupled light and matter

A team led by Rice University scientists used a unique combination of techniques to observe, for the first time, a condensed matter phenomenon about which others have only speculated. The research could aid in the development ...

Sending electrons on a rollercoaster ride

A first-of-its-kind X-ray instrument for frontier research with high-brightness X-rays is now in operation at Argonne National Laboratory. The new device utilizes a unique superconducting technology that speeds electrons ...
