However, the "stopping power" of silicon is limited; it doesn't efficiently absorb (and ultimately detect) x-rays of energies above approximately 20 keV. For x-ray science applications at higher energies (which are the primary mission of CHESS) different approaches are required; using Cadmium Telluride (CdTe) as a sensor material is one of them. The Gruner group at Cornell has chosen to develop CdTe-based versions of the world-leading MM-PAD and Keck PAD detectors, to allow experiments at x-ray energies up to 200 keV.

The Amazon Basin is a complex network of interconnected terrestrial and aquatic environments, with chemical diversity dictated by the bedrocks and soils through which river tributaries pass. Overfishing has led to considerable declines in some species, while deforestation is producing stronger, earlier flood pulses, altering the flood cycle that migratory fishes rely upon.

The planning for the CESR upgrades is well under way, with Dave Rice leading the charge. The beamline project is being led by Chris Conolly. The beamline design process has taken a methodical path involving our user community, scientific advisory panels, and an external review committee that met on Friday, December 16th.

The failure of these materials begins at the microscale, often deep within the bulk of the deforming material, with the formation of voids and cracks. Typically, failure of this type must be studied forensically using destructive optical or electron microscopy post-mortem, making the causes of the failure difficult to determine. With new in-situ high-energy X-ray techniques, long standing questions regarding the initiation of material failure can be answered, improving our ability to produce lightweight, long-lasting engineering components.

Along their way they stopped at middle schools across the country to teach hands-on lessons on renewable energy based on a mini 3D printed solar-powered bicycle called SolCycle. In the fall, one of the students, Elizabeth Case, enrolled at Cornell University as a graduate student and contacted Xraise to collaborate on enhancing the lesson plan and to make it more accessible to teachers across the nation.

The upgraded controls are similar to the A-Line controls and consists of a PLC driven touch screen interface which controls the station beam stops, and shows the status of the safety interlock devices for the station. The screen and PLC are connected to the CHESS controls and data network, which allows the status of other networked equipment to be displayed. At the A1 station, users and staff can now see the status of upstream beamline components to aid in beamline setup.

Four participants also joined the group via Webex from Buffalo and New York City. The institutions represented included Ithaca College (chemistry and art history), Hobart and William Smith Colleges (chemistry), SUNY Buffalo (art conservation), SUNY Stony Brook (conservation science), New York University (art conservation), the Metropolitan Museum of Art (art conservation), the Herbert F.

Usually, HPC has negligible effect on the crystal structure. Occasionally, it causes a small change in packing of the molecules in the crystal. For crystals containing a lot of solvent, pressure may cause them to collapse, destroying their diffraction. HPC on crystals of Snf7, however, results in a large change in molecular packing without destroying the crystallinity. In fact, the pressure-cooled crystals diffract better than the normally cooled crystals, in spite of a 30% decrease in unit cell volume!

Right! That’s exactly what the Xraise outreach team did, with a little help from the design superhero Ryan McGuire, on the homepage of their new web site launched this January 2016. The dynamic site, appropriate for audiences of all ages, will entice visitors to explore the pages and empower their minds with science!! Take a minute to tour the site at xraise.classe.cornell.edu
