Time-resolved X-ray absorption spectroscopy encompasses a suite of methods that probe structural and electronic dynamics in materials on timescales ranging from femtoseconds to seconds. At synchrotron ...

These great optics will get you a good view of the “blood moon,” but you can also use them long after the event to level up your stargazing.

Three-dimensional structured illumination microscopy (3D-SIM) doubles the resolution of fluorescence imaging in all directions and enables optical sectioning with increased image contrast. However, 3D ...

It would be appreciated if a reference to the following work, for which this package was originally built, is included whenever this code is used for a publication ...

TracePy is a sequential ray tracing package written in Python 3 for designing optical systems in the geometric optics regime. It features lens optimization from Scipy. To use TracePy you can either ...

We present a Python implementation of a D- and E-region chemistry and ionization code called pyGPI5. Particle precipitation that penetrates into the E- and D-region of the ionosphere-thermosphere ...

The structural link between meter-long DNA molecules and chromosomes a few microns in size and their highly space-effective and fault-free packing and unpacking mechanisms remain a puzzle. This ...

Serial electron diffraction (SerialED) is an emerging technique, which applies the snapshot data-collection mode of serial X-ray crystallography to three-dimensional electron diffraction (3D Electron ...

In this work, we present ultrafast (subpicosecond), submicrometer-resolution direct imaging of phonon propagation in bulk materials. To achieve this, we developed a unique X-ray diffraction microscopy ...
