Striking the right balance of intermolecular coupling for high-efficiency singlet fission
Singlet fission is a form of unconventional energy conversion that multiplies excitations. It can be used to harvest spectrally broad light, such as the sun, more efficiently. The incorporation of this process into optoelectronic devices, such as solar cells, would significantly boost efficiencies and reduce cost.
CHESS Addresses the "Middle-Skills" Gap with Partnership
CHESS, a power-house of x-ray and accelerator physics and technology, requires the cultivation of local talent, specific skills, and a highly-trained workforce to build and maintain needed beamline and accelerator components.
Two-Color X-ray Emission Spectroscopy Probes Enzyme Mechanism from Human Pathogen
Using two-color valence-to-core x-ray emission spectroscopy, researchers from Penn State and CHESS uncover new details about enzyme mechanism.
Thinking Past CHESS-U, Students Make an Impact
Grace King, a rising Junior, majoring in Physics at Vassar College and studying Engineering at Dartmouth College, participated in the REU program at Cornell this summer, and her research project is quite timely, as CHESS and CESR are currently undergoing their biggest upgrade in decades.
New Hutches Installed as CHESS-U Takes Shape
The construction portion of the CHESS-U upgrade is nearing completion as teams work to assemble the last of the experimental hutches. While there is still plenty of work to be done, the preparation for becoming a true 3rd-generation lightsource is paying off.
How Synthetic Diamonds Reflect X-rays
"A team of CHESS scientists cracked the problem for one of technologically important types of materials, chemically vapor-deposited (CVD) diamond crystals."
Shake, Rattle, and Roll: Studying the kinematics of Sand Grains during Compression
Granular materials are everywhere: they are underfoot in soils, sands, and snow and are also processed to create numerous food products, pharmaceuticals, and manufactured goods in our everyday lives.
Using X-rays to Validate the Next-Generation of Thermo-Mechanical Processing Codes
Additive manufacturing or ‘3-D Printing’ of metallic alloys promises to revolutionize manufacturing with its ability to eliminate waste, enable the production of parts with complex shapes previously not possible, allow replacement parts to be built in remote environments (e.g. at sea or in space), and reduce the costs of creating replacement parts for legacy equipment.
