Hyperpolarized contrast agents for MRI with long relaxation times
When the nuclear orientation of a material is hyperpolarized by techniques such as dynamic nuclear polarization, these materials can function as extremely effective contrast agents for magnetic resonance imaging (MRI). In most cases, however, the…

Ice lithography for high resolution electron beam processing of fragile substrates
Electron beam lithography is a staple of microfabrication processes. The dominant practice, developed for silicon etching, first uses an organic photoresist to coat the substrate and then writes a desired pattern. However, this process can damage or…
