explain modern methods in electron microscopy, electron diffraction, and spectroscopy. discuss the advantages and disadvantages of the different methods. describe the interaction between the inelastic ...

Yet, traditional far-field techniques are limited by diffraction, restricting their resolution to hundreds of nanometers, which can be inadequate for capturing phenomena in quantum and solid-state ...

By imaging the grating holographically, we retain tremendous flexibility in design as well as precise parameter control, allowing us to generate very high quality, highly custom diffraction gratings ...

The new approach, called coherently controlled quartz-enhanced photoacoustic spectroscopy, could form the basis for highly sensitive real-time sensors for applications such as environmental ...
