blog posts Making a Homemade COVID Mask? Study Explains Best Fabric Choices May 11, 2020 11:30 pm0 views Health authorities believe COVID-19 spreads by the transmission of respiratory droplets, and the Centers for Disease Control and Prevention recommends homemade cloth face coverings for use in public spaces. Starting today, Illinois joins many other states in requiring people to wear masks while out. However, initial uncertainty regarding the masks’ effectiveness in reducing exhaled droplets leaves some people unsure or skeptical of their usefulness during the current COVID-19 pandemic. Mechanical science and engineering professor Taher Saif spoke with News Bureau physical sciences editor Lois Yoksoulian about a study that he and his graduate students, Onur Aydin and Bashar Emon, performed on the effectiveness of common household fabrics for use in homemade masks. Abdelzaher Repurposing Social Networking Models to Predict COVID Spread Under Different Social Distancing Policies May 4, 2020 11:15 pm0 views Since the COVID-19 epidemic began, there has been plenty of opportunity to observe how a vast array of truths, half-truths, and falsehoods can flare up and spread like wildfire across social media, swirl around, and just as quickly get buried and forgotten.

New Understanding of Condensation Could Lead to Better Power Plant Condenser, De-icing Materials Feb 17, 2020 5:15 pm2 views For decades, it’s been understood that water repellency is needed for surfaces to shed condensation buildup – like the droplets of water that form in power plant condensers to reduce pressure. New research shows that the necessity of water repellency is unclear and that the slipperiness between the droplets and solid surface appears to be more critical to the clearing of condensation. This development has implications for the costs associated with power generation and technologies like de-icing surfaces for power lines and aircraft. Illinois ECE Student Leads Research Team to Explore Parallells Between Human Brain and Machine Feb 14, 2020 2:30 pm0 views The University of Illinois has been a champion of supercomputing since 1985, when the National Center for Supercomputing Applications (NCSA) became part of the National Science Foundation Network (NSFNET) – at a time when the internet, and modern-era computers, had just entered the early stages of development. Illinois continued to advance the computational game when the first widely used web browser, Mosaic, was built.

Smith's Theory of Pore-Scale Transport to Enable Improved Flow Batteries Jan 31, 2020 11:15 am0 views Redox flow batteries are an emerging technology for electrochemical energy storage that could help enhance the use of power produced by renewable energy resources. These power resources are inherently irregular in their supply, which doesn’t typically align with demand on the power grid. In principle, redox flow batteries can be designed to have an energy-storage capacity that is independent of its power rating. However, in practice, the ease with which redox-active molecules are transported to electrode surfaces plays an important role in determining their efficiency, the power that is produced or charged and, in some instances, their length of life.
