Mechanics of nozzle clogging during direct ink writing of fiber-reinforced composites
Recently, researchers and manufacturers have become interested in adding fiber reinforcement into polymer and ceramic materials produced by additive manufacturing (AM) to produce high-performance composite materials with exceptional strength in complex geometries. However, the amount of fiber that can be incorporated into these materials is limited by the propensity of fibers to clog the nozzle during deposition.

Stress Test for Remote Operations at CHESS
The test was dubbed a “stress test”, testing the strains on the bandwidth coming from outside of the lab, and into each station, with IT personnel monitoring each computer. As CHESS moves toward 100% remote operation for the fall run, CHESS staff is working to ensure a smooth transition, and these stress tests are proving useful.
MSN-C receives renewal of funding for second year
CHESS to restart in June for COVID-19 research
Funded by the National Institutes of Health, the research – to be led by Richard Cerione, the Goldwin Smith Professor of Chemistry and Chemical Biology in the College of Arts and Sciences, and Goldwin Smith Professor of Pharmacology and Chemical Biology in the College of Veterinary Medicine – focuses on cancer-fighting enzyme blockers, which have potential as SARS-CoV-2 inhibitors.
$54M for CHEXS, A New High-Energy X-ray Facility
CHESS is a national research facility that annually attracts more than 1,200 users who conduct X-ray analysis and collect data for research in materials, biomedical and other science fields. CHESS has been funded exclusively by the National Science Foundation since its commissioning in 1980.
