No comprehensive study has yet been carried out to characterize the photoexcited lattice dynamics of an opaque thin film on a semi-infinite transparent substrate. As a result, ultrafast X-ray diffraction data for such samples can be challenging to interpret. Now a new study builds a model to help interpret such data.

MIT chemists have developed new nanoparticles that can simultaneously perform magnetic resonance imaging (MRI) and fluorescent imaging in living animals. Such particles could help scientists to track specific molecules produced in the body, monitor a tumor's environment, or determine whether drugs have successfully reached their targets.

Imagine building a chemical reactor small enough to study nanoparticles a billionth of a meter across. A billion times smaller than a raindrop is the volume of an E. coli cell. And another million times smaller would be a reactor small enough to study isolated nanoparticles. Add to that the challenge of making not just one of these tiny reactors, but billions of them, all identical in size and shape. Researchers at Cornell have done just that.

Silicon is the second most-abundant element in the earth's crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices - carbon is to biology as silicon is to technology. A team of scientists has synthesized an entirely new form of silicon, one that promises even greater future applications.
