Back in 2001, I wrote a column about the merits of using heterogeneous designs for signal processing-oriented applications. My argument went like this: Signal-processing applications typically ...

The ultrafast laser excitation of matters leads to nonequilibrium states with complex solid-liquid phase-transition dynamics. We used electron diffraction at mega–electron volt energies to visualize ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...
