Diffraction at a Curved Grating: Approximation by an Infinite Plane Grating

Journal of Mathematical Analysis and Applications, 1996
The effect of curvature of a cylindrical grating on the diffraction of TE and TM polarized electromagnetic plane waves is considered. For every ratio of the wavelength \(\lambda\) to the period \(d\) a local approximation is established in the planar field by a plane infinite grating, when the radius \(R\) of the circular grating goes to infinity ...

A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

Advanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.
