Microcavities save organic semiconductors from going dark

Researchers found a way to keep these organic semiconductors from going dark. They used tiny sandwich structures of mirrors, called microcavities, to trap light and force it to interact with a layer of molecules, forming a new hybrid state, known as a polariton, that mixes light and matter.This approach could lead to brighter, more efficient LEDs, sensors and solar cells.

A new view for glasses

Scientists used computer simulations to demonstrate how the dynamics of a glassy liquid can be predicted based on the local structural ordering at the atomic level. This work may lead to a deeper understanding of glass transition.

Ultrafast x-ray optics

Scientists have demonstrated a new micro-electro-mechanical-system (MEMS) resonator. By using this device with a hard (higher energy) X-ray, scientists can now control how long the X-ray pulses are, down to 300 picoseconds long.

Super nanoparticle superlattices

Nanoparticle superlattices have properties that are different from both the individual particles and the bulk material. Ions and molecules called ligands bind particles together in these superlattices. New research shows how the ligands affect key structural and mechanical properties of the superlattices.

Anticipation of regulatory needs for nanotechnology-enabled health products

This new white paper, published by the European Commission, summarizes the major challenges associated with the regulation of the nano-enabled health products.
