ORNL contributes to developing the concept of passive CO2 DAC by designing and testing a hybrid sorption system. This design aims to leverage the advantages of CO2 solubility and selectivity offered by materials with selective sorption of adsorbents.

Electrochemistry synthesis and characterization testing  typically occurs manually at a research facility.

Materials produced via additive manufacturing, or 3D printing, can experience significant residual stress, distortion and cracking, negatively impacting the manufacturing process.

Carbon fiber is used in a wide range of manufacturing that utilize composite materials, from aerospace to golf clubs, as it has high strength and is lightweight. The process for manufacturing carbon fiber is complex and requires several stages.

A nondestructive method to measure a localized thermal expansion coefficient (LTEC), for anisotropic materials.

An optical metrology method measures anisotropic strain values when the composite is locally heated, which ultimately measures the local fiber orientation at a microscale resolution.

Next generation batteries for electric vehicles (EVs) and other manufacturing needs require solid-state batteries made with high-performance solid electrolytes. These thin films are critical components but are difficult to manufacture to meet performance standards.

Inorganic fillers play an important role in improving the ionic conductivity, electrochemical stability, and mechanical strength of solid composite electrolytes (SCEs) for next generation Li-ion batteries.

The technologies provide a system and method of needling of veiled AS4 fabric tape.

A bonded carbon fiber monolith was made using a coal-based pitch precursor without a binder.
