Elongated ring polymers get tied up in knots
News Article, October 13, 2022 • Many polymer liquids flow easily when stretched gently but become viscous and solid-like when stretched rapidly. This phenomenon, known as strain hardening, happens when the liquid is deformed so fast that individual polymer chains become elongated at the molecular scale. Understanding the physics of strain hardening is important for a range...

Fin-ion tunable transistor for ultra-low power computing 
News Article, June 7, 2023 • Work on this project revealed fundamental principles of electrochemical random access memory and established a viable path toward its integration with complementary metal-oxide semiconductor. Data-heavy workflows such as AI require in to increase system efficiency. Work on this memory computing, so this LDRD team focused on creating analog resistive nonvolatile...

Using the power of “super-small” to solve large-scale scientific problems
News Article, October 13, 2022 • Sandia builds a testbed for powerful quantum computing hardware and scientific applications. Try this thought experiment: imagine a small measurable quantity of something—perhaps a grain of sand or a point of light—then cut it in half, again and again. When you reach the smallest quantity, such as a photon of...
