The next generation of energy storage, sensors and neuromorphic computer logics in electronics rely largely on solving fundamental questions of mass and charge transport of ionic carriers and defects in materials and their structures. Here, understanding the defect kinetics in the solid state material building blocks and their interfaces with respect to lattice, charge carrier types and interfacial strains are the prerequisite to design novel energy storage, sensing and computing functions. Through this presentation basic theory and model experiments for solid state oxides their impedances and memristance, electro-chemo-mechanics and lattice strain modulations is being discussed as a new route for engineering material and properties on the examples of solid state batteries, environmental CO2 sensors and memristors for memory and neuromorphic computing chips. Central are the making of new oxide film materials components, and manipulation of the charge carrier transfer and defect chemistry (based on ionic and electronic carriers), which alter directly the device performances and new operation metrics.

Health care is shaping up to be one of the top issues of the 2020 presidential race. And with tens of thousands of Americans losing their health insurance to a coronavirus-induced recession, fears of inadequate or nonexistent health care coverage have never been greater. People ask, “Where am I going to get health insurance and how much is it going to cost me?” Each presidential candidate offers a very different view of the future of healthcare. President Trump promised to “come up with a great health plan,” one that would repeal the Affordable Care Act but replace it with something better while maintaining its biggest selling point: protecting people with pre-existing medical conditions. Joe Biden is pushing to build and expand on the Affordable Care Act. As for the COVID pandemic, Biden's proposals emphasize the role of the federal government leading the response, while Trump has delegated much to the states. What’s in store for the future? Join MIT’s Jonathan Gruber, Professor of Economics, for an interview on the Future of Healthcare After the Election.
