Structural and Material Properties of Chitin Nanofibers Produced Without Deacetylation Treatment

Nano Select
Deacetylation pretreatment is commonly applied to chitin nanofibers to introduce positive charges on their surface, increasing their fibrillation efficiency in water. However, without this treatment, chitin cannot be easily disintegrated into fibers with

Testing and Simulation of Multilayer Polyvinylidene Fluoride‐Based Piezoelectric Energy Harvester Devices

Advanced Materials Technologies, EarlyView.
The study considers the use of polymer/dielectric‐based multilayers piezoelectric Energy Harvesters (EH) to produce an output voltage and current, by exploiting the mechanical energy provided by human organs movements. In particular, the heart motion is considered from the kinematic viewpoint, and a multiphysics theoretical model is developed to assess

On‐Chip Saturated Absorption of CO2 in a Silicon‐on‐Sapphire Waveguide

Advanced Optical Materials, EarlyView.
We demonstrate the first saturated absorption of a molecular gas on a planar photonic chip. By coupling carbon dioxide with the tightly confined light of a silicon‐on‐sapphire waveguide, we achieve optical saturation using only milliwatt powers. This breakthrough provides a practical, low‐power foundation for creating ultra‐compact mid‐infrared ...
