Graphene photonics breakthrough promises fast-speed, low-cost communications

The fabrication and laser writing of this photonic material is simple and low cost.

Radiative cooling becomes more efficient with

An ideal radiative cooler requires accurate spectral control capability with high efficiency, stability, and scalability. Flexible cooling films represent a cost-effective solution but lack of accuracy in spectral control. Polymer metasurface with periodically arranged three-dimensional (3D) trench structures made by roll-to-roll printing can provide high-performance radiative cooling. The impressive cooling power and temperature deduction on a clear sky midday have been achieved, promising broad practical applications in energy saving and passive heat dispersion fields.
