Meet the Pioneer in Nanogeoscience
Alexandra Navrotsky, a trailblazer in nanogeoscience, is on an ambitious mission to understand the chemical foundations of planets beyond Earth. With over half a century of expertise under her belt, her research spans mantle mineralogy, deep Earth geophysics, and the intriguing thermodynamics of mineral formation. Notably, her contributions have led to the discovery of a new mineral named navrotskyite, cementing her legacy in the scientific community.
From the Big Apple to the Cosmos
Originally from New York City, Navrotsky's academic journey began with a BS, MS, and PhD in physical chemistry from the University of Chicago. Her love for the subject continues to fuel her curiosity, particularly regarding planetary exploration. If given the chance, she'd choose to explore Venus, where the potential for discovering life in its thick atmosphere captivates her imagination.
Understanding the Universe at the Nanoscale
At the helm of the Navrotsky Eyring Center for Materials of the Universe at Arizona State University, Navrotsky leads an innovative initiative focused on deciphering the materials that compose distant planets. Her work involves examining how materials behave under the extreme conditions of the universe, utilizing ASU's cutting-edge high-pressure and high-temperature research facilities.
The Power of Nanoscale Chemistry
Navrotsky emphasizes the importance of nanogeoscience in understanding planetary chemistry. At a nanoscale, where just a few atoms make up a particle, the reactivity and properties differ dramatically from larger particles. This knowledge is vital for deciphering the chemical processes that dominate planetary systems, from our solar system to exoplanets.
Exploring Planetary Materials: What Do We Know?
While scientists have gathered insights into planetary compositions, the complexities of materials on other worlds, including Mars and Jupiter, remain largely unexplored. Current knowledge is pieced together from rover data and planetary probes, but solid facts are still scarce. Navrotsky aims to unify these observations with theoretical chemistry to unveil the mysteries of planetary materials.
A Groundbreaking Initiative in Materials Research
Navrotsky's center is tackling critical questions about how intrinsic material properties affect planetary evolution and resource availability. By assessing the distinct environments of Venus, Earth, and Mars, she seeks to understand how nanoparticles influence geological and atmospheric transformations. Furthermore, this research could have profound implications for resource extraction, including potential mining from asteroids or other celestial bodies.
High-Pressure Materials Research: A New Frontier
Thanks to a recent $14.7 million grant from the U.S. National Science Foundation, ASU is set to advance its facilities for studying materials under extreme conditions. This research could unlock the reasons behind material compression and structural changes, providing insights into atomic interactions and leading to the discovery of new superconducting materials.
A Surprising Honor: Navrotskyite
The naming of the mineral navrotskyite after her was a moment of unexpected joy. Such honors are reserved for those who significantly contribute to the field of mineralogy, and Navrotsky's dedication has certainly earned her this recognition. Reflecting on her journey, she expresses gratitude for the opportunities that have come her way, rooted in her passion for science.
