Triaxial pressure cell in use at the Forming and Shaping Technology (FAST)beamline. This device can simulate pressures up to ~25 km below the surface.
High-Energy Diffraction Microscopy under Pressure
A triaxial pressure cell has been designed and constructed for use at the Forming and Shaping Technology (FAST) beamline, part of the NSF-funded Center for High Energy X-ray Sciences (CHEXS).

Growth pattern of caprine horn. Left: Diagram of a horn for a 5-year old goat indicating the layer of horn grown at each year of age. Right: Example of a horn cross section, indicating the layer of horn grown at each year of age.
Lead uptake and distribution in horns from goats
"Spatial analysis of horns for lead accumulation may be useful as a qualitative marker of time-resolved exposures that may reflect specific periods of acute lead absorption."

A Brilliant Relationship - Detector Development at Cornell
Through the CHESS-U upgrade, the X-rays produced at CHESS are now brighter than ever.  Combining these brilliant X-rays with new and inventive detectors developed by the Cornell Detector Group will provide new possibilities for X-ray experiments that are not possible today.

Lateral (membrane) views of structures in surface representation color coded in rainbow colors from amino (blue) to carboxyl (red) termini. Disordered regions are depicted as ribbon-only, and the catalytic serine is marked with an asterisk. The closed form (left) cannot accept either substrates or inhibitors. The cap-open structure (middle) that we visualized as a starting point in the bicelle can accept inhibitors but not substrates. Finally, the gate-open form (right) can accept both substrates and inhibi

Comparison of the real-space model of sodium ions in the x = 0 plane at 50K (top) with the deviation of the pair distribution function peak intensities from average, ΔPDF, (bottom) which is the basis of the model. ΔPDF peaks are at interatomic vectors connecting sites that are occupied with a greater (red) or lesser (blue) probability than random.
Nearest neighbors and beyond: Reciprocal space imaging of ionic correlations in intercalation compounds
"The ability to generate a real-space ‘image’ of interatomic vectors from reciprocal space data, makes this technique a powerful tool in the investigation of intercalation compounds, "
