Analytical investigation of nonreciprocal response in 1D nonlinear photonic crystals

open access: yesScientific Reports, 2017
The nonreciprocal response of the SHG process in 1D periodical nonlinear photonic crystals with a defect embedded has been theoretically studied by solving the nonlinear coupled equations. The nonreciprocal response has been deduced analytically with the

Parity Metamaterials and Dynamic Acoustic Mimicry [PDF]

open access: yesResearch (Wash D C)
While parity transformation represents a fundamental symmetry operation in physics, its implications remain underexplored in metamaterial science. Here, we introduce a framework leveraging parity transformation to construct parity-inverted counterparts ...

Half-metallic carbon nitride nanosheets with micro grid mode resonance structure for efficient photocatalytic hydrogen evolution

open access: yesNature Communications, 2018
The “storage” of sunlight as a chemical fuel can provide renewable on-demand energy, although current earth-abundant materials usually show low activities.

Acoustical properties of double porosity granular materials [PDF]

open access: yes, 2011
Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating properties. An emerging field is the study of the acoustical properties of multiscale porous materials.

Photoinduced semiconductor-metal transition in ultrathin troilite FeS nanosheets to trigger efficient hydrogen evolution

open access: yesNature Communications, 2019
While earth-abundant materials are promising catalysts for renewable energy conversion, such materials tend to display poor activities. Here, authors show FeS troilite nanosheets to undergo a near-infrared light-triggered transition to a phase that ...
