Our guest today is Stephen Steiner: President, CEO, and founder of Aerogel Technologies. Stephen has a PhD from the Massachusetts Institute of Technology in Materials Chemistry and Engineering which he completed in the Department of Aeronautics and Astronautics, and a Master’s Degree in Materials Science and Engineering, also from MIT.
Stephen has such an interesting story of really falling in love with science at a young age and doing so many interesting things on both the discovery side and the business side of science, really focused on aerogels.

Highlights of the episode:
*Susan introduces Stephen and today’s topic [1:24]; *Stephen tells us what aerogels are [3:20]; *Stephen talks about his middle school science fair projects which he did for extra credit, not because he liked science — at first! [4:27]; *Stephen’s high school science fair projects, now that he liked science! [6:09]; *Stephen’s foray into competitive science seminar with a teacher who taught him the algorithm for creativity [9:30]; *Things to consider when picking a research topic [12:23]; *Stephen’s first foray into making an aerogel [15:28]; *Removing a liquid from a gel while preserving the gel-like structure in a process called supercritical drying [21:10]; *Stephen decides to make an autoclave for supercritical drying [24:58]; *After FORTY tries, Stephen makes his first aerogel in his basement, at age 17! [30:00]; *Having a do-it-yourself attitude and persistence [35:14]; *Stephen’s experience with normal science classes while he was conducting real research in his basement in middle and high school [37:05]; *Undergrad institutions and what it takes to get in [45:04]; *Stephen applying to graduate programs and getting into MIT [49:05]; *Senior, established scientists like to help younger people who reach out for help [52:52]; *Stephen’s commitment to sharing knowledge and making knowledge accessible [53:22]; *Aerogels and their interesting properties [1:01:32]; *Why aerogels are such good insulators — the Knudsen effect [1:04:52]; *How do properties of elements perpetuate in aerogels made out of those elements? [1:10:27]; *How aerogels were first invented [1:15:29]; *Why making aerogels ends up breaking the ideal gas law [1:18:35]; *What does it mean when PV no longer equals nRT? [1:20:53]; *What is the critical point? Liquid and the gas become the same! [1:25:12]; *Properties of supercritical fluids and the magic in watching them form [1:29:12]; *Applications of aerogels kicked off by a listener question from Riley, a junior from the Chapin School, about aerogels and space travel [1:33:07]; *The challenging problem of insulating cryogenic tanks for rockets and potential for polyimide aerogels to solve this [1:37:07]; *What advice does Stephen have for students interested in science? Spoiler: Thorium! [1:45:40]

In this mini episode, Dr. Jonathan Bogan explains how insulin triggers the TUG protein to help move GLUT 4 transporter proteins from inside the cell to the cell membrane. There, they transport glucose from the bloodstream into the cell using facilitated diffusion. Tune in next week for the full-length interview. Hosted on Acast.

Dr. Dina Simkin is an Research Assistant Professor at Northwestern University's Feinberg School of Medicine whose research mainly focuses on how on how mutations in ion channel proteins contribute to pediatric epilepsy and neurodevelopmental disorders. Dr. Simkin earned her BS in Biochemistry, and then proceeded to earn PhDs in Neuroscience, Biophysics, and in Cellular and Molecular Pharmacology. She additionally completed post-graduate training in both the neurophysiology of aging and stem cell-derived neuronal models of epileptic channelopathy.

Lydia Pecker, M.D., is a pediatric hematologist and director of research and advocacy at the Sickle Cell Center for Adults at Johns Hopkins University. She previously served as the founding director of the Center's Young Adult Clinic, which was built to support young people transitioning from pediatric to adult care systems. She received her undergraduate degree in Africana studies from Brown University, earned her M.D. at the University of Pennsylvania School of Medicine, and received a Master's degree in Health Sciences from the Bloomberg School of Public Health.
