ALERT

In Observance of U.S. Holiday, M.L.K. Day, Agilent Cross Lab/ iLab Operations Software Support Help Desk will be closed during U.S. hours on Monday January 18th, 2021. We will resume regular U.S. support hours on Tuesday January 19th, 2021. EU and APAC Support will remain open during this time. For urgent matters, please add "Urgent" to the ticket/ email subject or press "1", when prompted, to escalate a call on the iLab Support phone and we will prioritize those requests first.

Vanderbilt Materials Durability and Environmental Research Facilities Hub

Overview of Services

The Materials Durability and Environmental Research Facilities Hub (MDERFH) supports research on the performance and durability of natural and engineered materials and systems exposed to a wide range of environmental conditions. A key component of the hub is the availability of research facilities that provide unique analytical services to the Vanderbilt community, as well as external academic and industry partners, through the hub's Core. Core operations are centralized in the Civil and Environmental Engineering Department at Vanderbilt University, and characterization techniques offered through MDERFH's Core include microscopy, spectroscopy, chromatography, crystallography, tribology, metrology, and micromechanics. The Core's instrumentation includes both user-run instruments, which require staff-led training prior to use, as well as staff-run instruments, where users will submit their samples directly to the Core. Staff-assisted sessions are available to users for an additional fee on all user-run instrumentation. The Leaching Environmental Assessment Framework (LEAF) Methods, a leaching evaluation system from the Environmental Protection Agency (EPA), is also available through the Core.
