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.
Separation of rare earth containing ores is often approached via froth floatation; however, for successful flotation, ligands must be designed that can both bind to the mineral interface while being amphiphilic enough to drag the minerals to an air-aqueous interface.
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.
Moisture management accounts for over 40% of the energy used by buildings. As such development of energy efficient and resilient dehumidification technologies are critical to decarbonize the building energy sector.
The co-processing of cathode and composite electrolyte for solid state polymer batteries has been developed. A traditional uncalendared cathode of e.g.
ORNL has developed a new thermal energy storage design utilizing low conductivity organic phase change materials.
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.
Nearly all electrochemical approaches to CO2 conversion rely on traditional fuel cell type electrocatalysis where CO2 is bubbled through acidic or basic media. The resulting electrochemistry leads to excessive generation of H2 over micromoles of CO2 conversion.
