Metalheads of Modern Science
Course Description
What makes metals different from other materials? From the first alloying done in the bronze ages to today’s ultra-strong nanoscale frameworks, the uniquely bendable and strong behavior of metals has enabled technology to advance for millennia. Today’s technology now uses the unique behaviors of metals to go beyond “classical metallurgy.” We now innovate by developing materials with carefully designed properties for a far wider range of applications. Our computers, cars, lasers, medicines, and other technology include innovations both in the materials and in how we use them. To understand important elements of science, technology and society that enable the world we live in today, we need to look more closely at how the materials behave.
This seminar introduces Materials Science and Engineering by exploring how metals enable a broad range of the science and technology all around us. We include labs and demonstrations, as well as guest speakers from a range of different careers and fields that use metals in their technology. Starting with the blacksmiths and metallurgists of ancient history, we will introduce the scientific innovations that have enabled today's technology. We will spend the rest of the course exploring how today's technology uses metals in new and innovative ways — far beyond the metallurgy of old. Students will learn how metals in their bodies can be used for diagnostics and treatments, how metals in geology can show us how planets form, how new metallic tools allow us to 3D print aircraft engines, and more! This will introduce students to the science of metals and explore the career paths that can follow from these technologies.
Meet the Instructor: Leora Dresselhaus-Marais
"I am an Assistant Professor in the Department of Materials Science and Engineering (MatSci) who specializes in developing sustainable ways to make metals. Trained in chemistry and optics, I develop new types of microscopes to 'see' new scientific insights that allow my group to solve important science gaps that challenge sustainable manufacturing today. My group develops both science and technology to create sustainable metals from the beginning to end of the supply chain. That includes decarbonizing steel production (8% of the global CO2 footprint) through 3D printing steel components and understanding how to build strong materials for extreme operating conditions.
"The question that excites me most about MatSci is: 'How can we use the science of tiny imperfections in materials (i.e., defects) to understand and control the materials around us that we rely on for our technology?’ This tantalizing question has inspired my career in Materials Science and Engineering and is one that we will explore in this class — through the lens of metals and the technology all around us."
