Patent number: 11815287Abstract: Using thermal radiation to supply occupant comfort has long existed in the heating domain, and to a lesser scale in the cooling domain. Cooling power of radiant cooling systems is limited by the risk of condensation on the panel itself, as well as adjacent surfaces.

Publication number: 20230332042Abstract: Biomineralization—the synthesis of inorganic materials using proteins—has recently gained interest as a low cost, green route for the production of metal chalcogenide semiconductor nanocrystals. Typical biomineralization approaches rely on proteins or biomolecules identified from organisms which possess a native biomineralization response. Disclosed herein is an alternative biomineralization approach for synthesizing metal chalcogenide nanocrystals which uses an artificially designed de novo protein. De novo proteins are non-natural proteins, allowing for facile modification of the protein through the tuning of amino acids within the sequence. This de novo protein was employed to produce size-controlled populations of semiconductor nanocrystals, with properties consistent with those produced using traditional routes.Type: ApplicationFiled: March 7, 2023Publication date: October 19, 2023Applicant: The Trustees of Princeton UniversityInventors: Michael Hecht, Sarangan Chari, Leah Spangler
