Observing a molecule stretch and bend in real-time

Being able to watch how molecules bend, stretch, break or transform during chemical reactions requires state-of-the-art instruments and techniques that can observe and track all the atoms within a molecule with high sub-atomic ...

Colloidal quantum dots make LEDs shine bright in the infrared

The ideal optoelectronic semiconductor material would be a strong light emitter and an efficient charge conductor to allow for electrical injection in devices. These two conditions, when met, can lead to highly efficient ...

Insulator-metal transition at the nanoscale

Controlling the flow of electrons within circuits is achieved through the appropriate choice of materials. Metals allow electrons to flow freely and insulators prevent conduction. In general, the electrical properties of ...

The photoexcited graphene puzzle solved

Light detection and control lies at the heart of many modern device applications, such as the cameras in phones. Using graphene as a light-sensitive material for light detectors offers significant improvements with respect ...

An ultradilute quantum liquid made from ultra-cold atoms

ICFO researchers created a novel type of liquid 100 million times more dilute than water and 1 million times thinner than air. The experiments, published in Science, exploit a fascinating quantum effect to produce droplets ...

Fast flowing heat in graphene heterostructures

Nanoscale heat flow plays a crucial role in many modern electronic and optoelectronic applications, such as thermal management, photodetection, thermoelectrics and data communication. Two-dimensional layered materials could ...
