The use of biomass fiber reinforcement for polymer composite applications, like those in buildings or automotive, has expanded rapidly due to the low cost, high stiffness, and inherent renewability of these materials. Biomass are commonly disposed of as waste.
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.
High strength, oxidation resistant refractory alloys are difficult to fabricate for commercial use in extreme environments.
We have developed an aerosol sampling technique to enable collection of trace materials such as actinides in the atmosphere.
The invention addresses the long-standing challenge of inorganic phase change materials use in buildings envelope and other applications by encapsulating them in a secondary sheath.
The technologies described herein provides for the High Temperature Carbonization (HTC) in the manufacturing of carbon fibers (CF). The conventional method for HTC is based in thermal radiation and this technology uses in a liquid medium.
