Understanding secondary light emission by plasmonic nanostructures may improve medical imaging

Applications in imaging and sensing typically involve the emission of light at a different wavelength than the excitation, or 'secondary light emission'. The interpretation of resonant secondary light emission in terms of fundamental processes has been controversial for 40 years. In this work, researchers found that resonant electronic Raman scattering and resonant fluorescence may both be useful descriptions of the secondary emission.

No nano-dust danger from facade paint

After 42 months the EU research project NanoHouse has ended, and the verdict is a cautious 'all clear' - nanoparticles in the paint used on building facades do not represent a particular health risk.

Towards perfect control of light waves

Researchers have constructed a detector, which provides a detailed picture of the waveforms of femtosecond laser pulses. Knowledge of the exact waveform of these pulses enables scientists to reproducibly generate light flashes that are a thousand times shorter - lasting only for attoseconds - and can be used to study ultrafast processes at the molecular and atomic levels.

Using micro-windmills to recharge cell phones

Researchers have designed a micro-windmill that generates wind energy and may become an innovative solution to cell phone batteries constantly in need of recharging and home energy generation where large windmills are not preferred.

'Superlens' extends range of wireless power transfer

Inventor Nikola Tesla imagined the technology to transmit energy through thin air almost a century ago, but experimental attempts at the feat have so far resulted in cumbersome devices that only work over very small distances. But now, Duke University researchers have demonstrated the feasibility of wireless power transfer using low-frequency magnetic fields over distances much larger than the size of the transmitter and receiver.

A nanotechnology formulation for glaucoma

Researchers have developed a nanocarrier with the capability of sustained release for ocular indications. Specifically, the developed nanocarrier demonstrated sustained efficacy and proved to be well tolerated in a diseased nonhuman primate model, making it a prime sustained-release nanomedicine candidate for glaucoma therapy.
