To achieve high sensitivity and uniformity simultaneously in a surface-enhanced Raman scattering (SERS) substrate, this paper presents the preparation of flexible transparent three-dimensional (3D) ordered hemispherical array polydimethylsiloxane (PDMS) film. This is achieved by self-assembling single-layer polystyrene (PS) microsphere on silicon substrate. The liquid-liquid interface method then used to transfer Ag nanoparticles onto PDMS film, which includes open nanocavity arrays created...
Moisture-enabled electric generations (MEGs) are highly promising in next-generation energy conversion, while those derived from sustainable biomass still their infancy. Protein nanostructures possess intriguing abilities to harness ion transportation for bioelectricity generation. Herein, quality-enhancing MEGs with silk cocoon-like structure were developed. In this context, fibroin nanofiber film was first electrospun, and a sericin concentration gradient along the thickness direction...
