Measuring nanoparticles with light

May 4, 2012 – 12:00 am

A colourful way to size up nanoparticles - A property of nanoparticles commonly exploited in a wide range of applications can be turned on the nanoparticles themselves to give scientists an estimate of the particles' size. Researchers in China have now developed a straightforward light-scattering technique to estimate the size of gold nanoparticles in the 35 to 110nm range. Reference: C Jing et al, Anal. Chem., 2012, DOI: 10.1021/ac203118g

Hybrid copper-gold nanoparticles convert CO2

April 12, 2012 – 6:00 am

Hybrid copper-gold nanoparticles convert CO2 - Now researchers at MIT have come up with a solution that may further reduce the energy needed for copper to convert carbon dioxide, while also making the metal much more stable. Co-author Kimberly Hamad-Schifferli of MIT says the findings point to a potentially energy-efficient means of reducing carbon dioxide emissions from powerplants. A paper detailing the results will appear in the journal Chemical Communications.
