|5811180||Pigments which reflect infrared radiation from fire|
Conventional paints transmit or absorb most of the intense infrared (IR) radiation emitted by fire, causing them to contribute to the spread of fire. The present invention comprises a fire retardant paint additive that reflects the thermal IR radiation em...
|4628695||Solid state radiative heat pump|
A solid state radiative heat pump (10, 50, 70) operable at room temperature (300° K.) utilizes a semiconductor having a gap energy in the range of 0.03-0.25 eV and operated reversibly to produce an excess or deficit of charge carriers as compared to ther...
|4586350||Selective radiative cooling with MgO and/or LiF layers|
A material for a wavelength-selective radiative cooling system, the material comprising an infrared-reflective substrate coated with magnesium oxide and/or lithium fluoride in a polycrystalline form. The material is non-absorptive for short wavelengths, a...
