The incorporation of low embodied carbon building materials in the enclosure is increasing the fuel load for fire, increasing the demand for fire/flame retardants.
This technology identifies enzymatic routes to synthesize amide oligomers with defined sequence to improve polymerization of existing materials or enable polymerization of new materials. Polymers are generally composed of one (e.g. Nylon 6) or two (e.g.
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 traditional window installation process involves many steps. These are becoming even more complex with newer construction requirements such as installation of windows over exterior continuous insulation walls.
The use of class A3 and A2L refrigerants to replace conventional hydrofluorocarbons for their low global warming potential (GWP) presents risks due to leaks of flammable mixtures that could result in fire or explosion.
The quality and quantity of refrigerant charge in any vapor compression-based heating and cooling system is vital to its energy efficiency, thermal capacity, and reliability.
Performance of heat exchangers greatly suffers due to maldistribution of fluid, which also impacts the performance of the entire HVAC system. One method to reduce fluid maldistribution is to improve the design of the manifold to make the flow evenly distributed.
Most plastic is discarded after a single use, with about 76 percent of plastic waste discarded into landfills annually. The current practice is wasting feedstock resources, energy, and carbon used for their production.
Adhesives for metal parts typically are liquid-based which require complex processing. This technology is a hot melt adhesive that is mixed and applied in a solid form and after the heating and cooling cycle creates strong bonds with the substrates in a matter of seconds.
