Affordable Biogenic Anti‐Icing Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
The article explores affordable biogenic coatings that prevent icing by combining coconut shell charcoal with natural hydrophobic agents such as beeswax. It shows how particle size and surface treatment influence water repellence, heat absorption, and self‐cleaning ability.

Microneedles From Shape‐Preserving Crosslinked Poly(Vinyl Alcohol) Hydrogels: Minimising Interference in Transdermal Proteomics

open access: yesAdvanced Materials Technologies, EarlyView.
Hydrogel‐forming microneedle patches are developed using shape‐preserving PVA‐PVP hydrogels, with and without chitosan, for minimally invasive transdermal protein biomarker sampling. The optimised patches enable efficient interstitial fluid uptake and proteomic analysis, while minimising interference.

Phase Topology Stability of an Optical Vortex via an Electrically Controlled Twist‐Planar Oriented Liquid Crystal Fresnel Lens

open access: yesAdvanced Optical Materials, EarlyView.
A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...
