Alec Pfundheller, a graduate student intern from Texas A&M University, and his mentor, Dr. Stephen Taller from the Nuclear Energy and Fuel Cycle Division, perform transmission electron microscopy to investigate radiation damage in additively manufactured type 316 stainless steels. The images depict different patterns produced by the electrons as they scatter off the face centered cubic structure of the steel. These investigations are routinely performed at ORNL’s Low Activation Materials Development and Analysis laboratory on irradiated materials.

ORNL is partnering with sustainable battery recycling company Nth Cycle to develop methods for recycling the type of lithium-ion batteries that power electric vehicles. This black powder is made of cathode materials that were synthetized from recovered battery components. ORNL researchers are improving the efficiency of Nth Cycle’s electroextraction technology, which is based on removing charged particles from spent electrodes and selectively separating metal hydroxides for reuse in new electrodes. At ORNL’s Battery Manufacturing Facility in Hardin Valley, the extracted metal hydroxide is incorporated into new cathodes, which undergo testing to demonstrate properties on par with batteries made from pristine materials.
In the Bioanalytical Mass Spectrometry group in the Biosciences Division, John “Jack” Cahill, Stephen Zambrzycki and Vilmos Kertesz are developing technologies to measure metabolites and lipids from a single cell. These new measurement tools enable deeper insights into cell biology and how well therapies may work. Two key technologies are being combined. First in collaboration with HP Life Science Solutions, inkjet printer technology is being used to isolate and dispense a single cell at a time in a robust inexpensive platform. The second technology is the Open Port Sampling Interface (OPSI) developed at ORNL. Cells dispensed by the HP D100 Single Cell Dispenser are taken, extracted, and ionized into a mass spectrometer through the OPSI to measure the metabolites and lipids in a cell. In the photo, the researcher is loading the HP D100 Single Cell Dispenser cassette with a solution of single cells that will be dispensed into the OPSI below. A single cell can be analyzed every couple of seconds with this technology. Each measurement is a snapshot of the chemical signaling and biology of an individual cell. This snapshot helps isolate the wide variety of cell responses to treatments and conditions despite similar genes.

A metallic, ferromagnetic thin plate several microns in length and only 100 nm in thickness mounted on a focused ion beam lift-out transmission electron microscopy grid. Using Lorentz TEM, we can observe the intrinsic spin arrangements within the thin plate at cryogenic temperatures.
Coal granules are prepared for loading into a reactor that converts coal to char and coal liquids. ORNL researcher Vlad Lobodin has been optimizing the process in a lab at the Spallation Neutron Source. His pyrolysis furnace there can process a kilogram of this coal at a time.

Bishnu Thapaliya, a researcher in the Nanomaterials Chemistry group, creates and tests coin cell batteries that incorporate graphite made from coal in reactors at ORNL, April 16, 2024. He and other ORNL researchers are converting coal into char and liquids, then using these particles to make the rare mineral graphite, which is needed for the electrodes used in electric vehicle batteries.

Building Technologies Research and Integration Center - Troy Seay works in the AgPod on the BTRIC campus. The AgPod is a self-contained indoor vertical growth environment built inside a modified shipping container. The AgPod is being used to demonstrate carbon capture utilization and sustainable food production. Mature kale plants are shown in the vertical growth panels in the back of the AgPod . The illuminated LED grow lights show the crops are undergoing a simulated daylight growth cycle.
DLS measures the scattering of light from a laser to determine the diameter of particles as small as 10x the diameter of a single atom. It also lets you know the relative amounts of each particle size from a minimum diameter to a maximum diameter which is called the size distribution. UV-Vis spectroscopy gives information on the molecular absorption of light in the ultraviolet and visible regions. The maximum wavelength of absorption corresponds to electronic transitions of the molecules of interest. The resulting spectra are plotted as absorbance versus wavelength.

A sample being analyzed using FT-IR spectroscopy. FT-IR spectroscopy is a light scattering technique that allows us to probe the vibrations of molecules following interaction with infrared light. The unique spectra obtained have peaks at certain locations where the infrared light was absorbed. The location of these peaks tell us what types of chemical bonds our samples have and can help identify or confirm the presence of certain molecules.
