As a student representative to the ALS Users Executive Committee (UEC) for the past two years, Mahati Chintapalli has gained a better understanding of how the ALS functions as an organization, while the UEC has gained a devoted and outgoing member. She’s currently a PhD student in Materials Science and has been conducting research at the ALS since 2011. Read more »
The influence of molecular orientation on organic bulk heterojunction solar cells
Work done on ALS Beamlines 11.0.1.2, 7.3.3, and 5.3.2.2. reveals that preferential orientation of polymer chains with respect to the fullerene domain leads to a high photovoltaic performance. Read more »
The Molecular Ingenuity of a Unique Fish Scale
ALS research has shown how the scales of a freshwater fish found in the Amazon Basin can literally re-orient themselves in real time to resist force, in essence creating an adaptable body armor. Read more »
Self-Assembly of “S-Bilayers”, a Step Toward Expanding the Dimensionality of S-Layer Assemblies
Protein-based assemblies with ordered nanometer-scale features in three dimensions are of interest as functional nanomaterials but are difficult to generate. Here we report that a truncated S-layer protein assembles into stable bilayers, which we characterized using cryogenic-electron microscopy, tomography, and X-ray spectroscopy. Read more »
