Foams‐Induced Hierarchy for Multiscale Photonics on Flat Substrates: Lasing and Mie‐Bragg Diffraction as Case Studies.

open access: yesAdvanced Materials Interfaces, EarlyView.
Ordered and disordered complex configurations displaying two levels of functionality can be fabricated using a simple self‐assembly method involving the foaming and casting of suspensions containing monodisperse spheres on unpatterned flat substrates.

X‐Ray and Electron Spectroscopy of the CdS/(Ag,Cu)(In,Ga)Se2 Interface With RbF Treatment

open access: yesAdvanced Materials Interfaces, EarlyView.
The chemical and electronic structure of the CdS/(Ag,Cu)(In,Ga)(S,Se)2 interface with RbF treatment is investigated using a combination of synchrotron‐ and laboratory‐based soft and hard X‐ray spectroscopies. A Rb–In–Se species is found at the absorber surface, with a band gap of 2.8 eV, in contrast to comparable Ag‐free Cu(In,Ga)Se2 absorbers with RbF‐

Label‐Free Impedimetric Determination of Cortisol Using Gold Nanoparticles Functionalized Laser‐Induced Graphene Interdigitated Electrodes

open access: yesAdvanced Materials Technologies, EarlyView.
Non‐faradaic label‐free impedimetric determination of cortisol is demonstrated with gold nanoparticles (AuNP) functionalized laser‐induced graphene interdigitated electrodes (LIG‐IDE). The AuNP functionalized LIG‐IDE exhibits remarkable characteristics including good logarithmic linear range, high reproducibility, repeatability, and robust selectivity.

Wavelength‐Selective, High‐Speed, Self‐Powered Isotype Heterojunction n+‐ZnO/n‐Si Photodetector with Engineered and Tunable Spectral Response

open access: yesAdvanced Materials Technologies, EarlyView.
Wavelength‐selective ZnO/Si photodetectors, operating with no power supply. Engineering of the constituting materials converts them from white‐light sensitive to only NIR‐sensitive. When external power is applied, the wavelength selectivity of the devices can be tuned to different spectral ranges.
