Wrinkle‐Template Confinement of Kinetically Arrested Cellulose Nanocrystals for Sustainable Large Scale Reflection Gratings

open access: yesAdvanced Optical Materials, EarlyView.
Self‐supported all‐cellulose reflective gratings are fabricated from cellulose nanocrystal dispersions via a confinement printing process. Taking advantage of the reduced fluidity of concentrated, kinetically arrested cellulose nanocrystal dispersions, line arrays can be successfully transferred to dried CNC films.

Numerical Aperture Dependence of Mie Modes in Low Refractive Index Particles and Enhanced Collection Using Metallic Substrates

open access: yesAdvanced Optical Materials, EarlyView.
The influence of numerical aperture (NA) on the detection of Mie resonances in dielectric spheres is demonstrated. Experiments and simulations reveal that varying NA modifies mode amplitudes and linewidths. Furthermore, metallic substrates redirect modes toward low angles, enabling efficient mode detection with low NA optics and reducing perturbation ...

Competitive Bidirectional Response in Bi‐Polymeric Mechanochromic Cantilevers Toward Color Imaging‐Based VOC Discrimination

open access: yesAdvanced Optical Materials, EarlyView.
In bi‐polymeric mechanochromic cantilevers composed of polydimethylsiloxane (PDMS) and off‐stoichiometry thiol‐ene‐epoxy (OSTE+), differential swelling between the two polymers in response to VOC exposure induces a competitive bidirectional bending and corresponding color changes, with three characteristic response modes related to the Hansen ...
