The Cornell participants include chemists Nozomi Ando and Steve Meisburger. Experimental work will be conducted at the Cornell High Energy Synchrotron Source (CHESS).
In food products, the natural blues tend to be moody.
A fun food colorant with a scientific name – phycocyanin – provides a vivid blue pigment that food companies crave, but it can be unstable when placed in soft drinks and sport beverages, and then lose its hues under fluorescent light on grocery shelves.
For two short days on the Cornell Campus, the students from around the country - including four students from Puerto Rico - were able to meet their mentors from CHESS and their peers from other community colleges and undergraduate institutions. Their trip to Cornell offered the opportunity to tour the CHESS facility, explore the Ithaca area, and present their summer projects to an audience of CHESS directors, graduate students, and their fellow summer research students.
The FAST beamline focuses on high energy monochromatic techniques in diffraction and imaging. These techniques are applied to in situ sample environments in order to investigate the microstructure of materials while they are being mechanically loaded, thermally cycled, and/or being processed or built up (as in 3D printing).
Elisabeth Bodnaruk seems very comfortable as she looks into the container of liquid nitrogen. At -321 degrees F, liquid nitrogen is widely used throughout CHESS, but right now she is using it to commission some Resistance Temperature Detectors (RTDs). These RTDs will be placed in two silicon crystal monochromators where they will transmit temperature readings, and are an integral part of daily operations in the lab.
