Polymer solar cells employing Forster resonance energy transfer

Two crucial tasks exist for realizing high-efficiency polymer solar cells: increasing the range of the spectral absorption of light and efficiently harvesting photo-generated excitons. In this work, Förster resonance energy ...

White glow: Dye-doped DNA nanofibers emit white light

(PhysOrg.com) -- Efficient energy transport plays an important role in the development of optoelectonic materials. The true masters of energy transfer via a hierarchical arrangement of different molecules are the photosynthetic ...

Researchers' golden touch enhances quantum technology

Scientists at the U.S. Naval Research Laboratory discovered a new platform for quantum technologies by suspending two-dimensional (2-D) crystals over pores in a slab of gold. This new approach may help develop new materials ...

Electrons take one step forward without two steps back

Researchers at the University of California, Riverside, have, for the first time, successfully used electric dipoles to completely suppress electron transfer in one direction while accelerating in the other. The discovery ...

Surfing on waves in a one-dimensional quantum liquid

Physicists from the University of Luxembourg, together with international collaborators, have recently published an article in the internationally renowned journal Physical Review Letters. In this article, they demonstrate ...

Making rusty polymers for energy storage

It's called a nanoflower, but if you could brush your cheek against its microscopic petals, you would find them cool, hard and … rusty.

Invisibility cloaking to shield floating objects from waves

A new approach to invisibility cloaking may one day be used at sea to shield floating objects – such as oil rigs and ships – from rough waves. Unlike most other cloaking techniques that rely on transformation optics, ...
