Efficient thermal management in polymers is essential for developing lightweight, high-strength materials with multifunctional capabilities.
The disclosure is directed to optimized fiber geometries for use in carbon fiber reinforced polymers with increased compressive strength per unit cost. The disclosed fiber geometries reduce the material processing costs as well as increase the compressive strength.
Understanding building height is imperative to the overall study of energy efficiency, population distribution, urban morphologies, emergency response, among others. Currently, existing approaches for modelling building height at scale are hindered by two pervasive issues.
A novel and cost-effective process for the activation of carbon fibers was established.

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.
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.
The widespread use of inexpensive salt hydrate-based phase change materials, or PCMs, has been prevented by a key technical challenge: phase separation, also known as incongruency, which results in the significant degradation of the materials' ability to store thermal energy o
