High‐Efficiency Thermal‐Shock Resistance Enabled by Radiative Cooling and Latent Heat Storage

Advances in Materials
Radiative cooling technology is well known for its subambient temperature cooling performance under sunlight radiation. However, the intrinsic maximum cooling power of radiative cooling limits the performance when the objects meet the thermal shock. Here,

Both sub-ambient and above-ambient conditions: a comprehensive approach for efficient use of radiative cooling

Energy & Environmental Science
In real-world radiative cooling applications, cooling surface temperatures may periodically fluctuate between sub- and above-ambient conditions. Traditional radiative cooling surface with ‘static’ spectral properties cannot realize high efficiency ...

Cellulose Metamaterials with Hetero‐Profiled Topology via Structure Rearrangement During Ball Milling for Daytime Radiative Cooling

Advanced Functional Materials
Passive radiative cooling is a zero‐energy consumption approach, which can dissipate heat to outer space by emitting infrared radiation through the transparency window. Traditional cooling materials, such as photonic films, metafabrics, and polymer foams,

Radiatively cooled scramjet combustor

2009
The construction of combustion chambers for scramjets that can survive the heating loads and dissipate the energy of a flight effectively remains a great challenge. In addition to surviving the conditions of supersonic combustion, the structure must be designed to minimise weight to optimise the performance of the engine.

Radiative Cooling Meta-Fabric Integrated with Knitting Perspiration-Wicking and Coating Heat Conduction.

ACS Nano
Radiative cooling is an emerging zero-energy-consumption technology for human body cooling in outdoor scenarios during hot seasons. However, existing radiative cooling textiles are limited by low intrinsic cooling power, high hydrophobicity, and heat ...

Near-Field Radiative Cooling of Nanostructures

Nano Letters, 2012
We measure near-field radiative cooling of a thermally isolated nanostructure up to a few degrees and show that in principle this process can efficiently cool down localized hotspots by tens of degrees at submicrometer gaps. This process of cooling is achieved without any physical contact, in contrast to heat transfer through conduction, thus enabling ...

Radiative cooling of C₇⁻.

The Journal of chemical physics, 2014
The spontaneous and photo-induced neutralization of C₇⁻ produced in a laser ablation source was measured in an electrostatic storage ring. The measurements provide three independent determinations of the radiative cooling of the ions, based on the short time spontaneous decay and on the integrated amplitude and the shape of the photo-induced ...
