Our recent work on tfPDF has been highlighted on the BNL website! Functional thin films are deposited onto a substrate, often silicon, silicon dioxide, or aluminum oxide. This makes it difficult to study the thin film structure because of the small amount of film material and large amount of substrate. To minimize the scattering of… Read More tfPDF: Thin film PDF
Combining X-ray diffraction and PDF with computed tomography allows for spatially resolved structural analysis, which can help unravel structures in heterogeneous materials and map out the phases present in the system. We recently demonstrated this in a paper on complex structures in batteries, where we were able to map out the components in commercial AAA batteries… Read More X-ray diffraction computed tomography reveals inner structure in batteries
In 1915, Peter Debye published his paper: “Zerstreuung von Röntgenstrahlen” where he showed how X-rays scatter from non-periodic structures and derived what would later be known as the “Debye Scattering Equation”. To commemorate the 100 years of Debye Scattering, the workshop DSE2015 was held in the heart of the Dolomites in Italy. Here, 50 participants… Read More Billinge group at DSE2015
Congratulations to Vicky Doan-Nguyen for being awarded a prestigious UC President’s post-doctoral fellowship. In collaboration with grad student Vicky, her group at UPenn, and scientists at ESRF, the European synchrotron, we discovered an interesting connection between glassy disorder seen in small metallic nanoparticles and in the technologically interesting bulk metallic glasses (BMGs): Vicky V. T.… Read More Collaborator Vicky Doan-Nguyen awarded prestigious UC President’s post-doctoral fellowship
