Temperature-independent thermal radiation [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance Conventional wisdom states that the hotter an object is, the brighter it glows. This is the case for thermal light at any wavelength and enables applications such as infrared imaging and noncontact thermometry. We demonstrate a coating that emits the same amount of thermal radiation irrespective of temperature, within a ...

Observation of nonvanishing optical helicity in thermal radiation from symmetry-broken metasurfaces. [PDF]
Sci Adv, 2023 We experimentally demonstrate magnetic-field-free circular-polarized thermal radiation based on a symmetry-broken metasurface. A nonvanishing optical helicity in the radiation excited by thermal fluctuations is observed in a dispersionless energy band.

Violating Kirchhoff’s Law of Thermal Radiation in Semitransparent Structures [PDF]
Conference on Lasers and Electro-Optics, 2021 We design a nonreciprocal thermal emitter that features absorptivity-emissivity contrast in semitransparent setting, by using magneto-optical effect.

Nonlinear flow of hybrid nanofluid with thermal radiation: A numerical investigation
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2023 In this research, we investigate the mixed convection flow of hybrid nano fluid over nonlinear stretching sheet. By imposition of Cu‐Al2O3 as nanoparticles, water as base fluid. Impact of thermal radiation in the existence of magnetic field is considered.

All-weather thermochromic windows for synchronous solar and thermal radiation regulation
Science Advances, 2022 Adaptive control of solar and thermal radiation through windows is of pivotal importance for building energy saving. However, such synchronous passive regulations are challenging to be integrated into one thermochromic window.

Investigation of Zebrafish Embryo Membranes at Epiboly Stage through Electrorotation Technique
Membranes, 2023 A preliminary exploration of the physiology and morphology of the zebrafish embryo (ZFE) during the late-blastula and early-gastrula stages through its electrical properties was performed, applying the electrorotation (ROT) technique.

Dynamic thermal radiation regulation for thermal management
Next Energy, 2023 With the improvement of living standards, energy consumption for heating and cooling is increasing. Traditional heaters or coolers (air conditioners etc.) consume lots of energy and only transfer heat to different places on Earth, which increases the ...
