TL;DR: A self-assembling plasmonic absorber which can enable an average measured absorbance of ~99% across the wavelengths from 400 nm to 10 μm is reported, the most efficient and broadband plas Monte Carlo absorber reported to date.

TL;DR: An efficient strategy using extremely low‐cost materials, i.e., carbon black (powder), hydrophilic porous paper, and expanded polystyrene foam is reported, which can provide an approach for individuals to purify water for personal needs, which is particularly suitable for undeveloped regions with limited/no access to electricity.

TL;DR: A dielectric grating that can launch surface plasmon resonance (SPR) modes efficiently on the other side of flat metal films, which is similar to the conventional prism coupling mechanism, was proposed in this paper.

TL;DR: An example with near perfect energy conversion efficiency in the process of solar vapor generation below room temperature is reported, when the operational temperature of the system is below that of the surroundings and the total vapor generation rate is higher than the upper limit that can be produced by the input solar energy because of extra energy taken from the warmer environment.

TL;DR: A hyperbolic metamaterial waveguide is proposed to realize a highly efficient rainbow trapping effect, which can be used to develop practical on-chip optical super absorbers with a tunable absorption band.
