Welcome to the ASU Core Facilities Newsletter. We are ready to support all your research goals. Please follow our LinkedIn page for additional resources and community information.



ASU is working to increase the power density of batteries while decreasing battery size through new materials and process and manufacturing techniques to improve the future of power storage. The ASU Core Research Facilities house numerous pieces of specialized equipment and expert staff that support battery research and development, from fabrication to testing.

Eyring Materials Center

EMC proudly supports the AMPED initiative, contributing to the acquisition of advanced technologies like Sigray, PrismaE SEM, CleanMill and air-sensitive XPS holders.

These enhancements, made possible through AMPED funding, highlight EMC's commitment to fostering innovation within our community.

EMC supports the AMPED STC batteries initiative by offering a diverse array of instrumentation.

Raman Spectroscopy

Raman spectroscopy

Uses a fingerprint technique to identify materials based on vibrations. Its sensitivity gives information on composition and strain.

Electron Microscopy

CleanMill ion beam polisher paired with the Clean connect transfer system ensures air-free sample transport from the ion polishing instrument to the new Prisma E SEM.

Prisma environmental SEM, installed in December 2023, will be available for general SEM imaging as well as imaging of samples loaded via the air free transport ensuring no surface change due to interaction with air.

TEM also offers multiple battery material analysis options, available at both ambient and cryogenic temperatures


How EMC supports materials science.

A hydrogen-enriched layer in the topmost outer core sourced from deeply subducted water

We're proud to acknowledge that some of this groundbreaking research utilized resources from Arizona State University's METAL Core, showcasing the impact of our facilities on global scientific advancements.


The researchers' experiments reveal that water interacting with Fe–Si alloys under core–mantle boundary conditions produces SiO2 and FeHx, potentially explaining the distinct properties of the Eʹ layer and indicating a long-term chemical exchange between Earth's core and mantle.


The Earth's outer core is 10% less dense than pure iron-nickel alloy, suggesting the presence of lighter elements. Our study focuses on a new hydrogen-silicon exchange process at the core-mantle boundary (CMB), shedding light on the Eʹ layer's formation and the development of chemical heterogeneities.


Water from minerals reacts with Fe–Si, hydrogenating iron and oxidizing silicon into silica, which may transform ferropericlase into bridgmanite or post-perovskite.
