Polarisation and Disinformation in Brazil's COVID19 Vaccination Onset on X (former Twitter)
In January 2021, Brazil had a critical moment in its battle against the COVID-19 pandemic, marked by the beginning of the vaccination campaign. The country, facing a high number of deaths and transmission, was a battleground for polarised discussions ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
Advanced Functional Materials, EarlyView.We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Advanced Functional Materials, EarlyView.A new class of photoresponsive liquid‐crystalline (LC) adhesives based on biomineral‐inspired organic/inorganic colloidal hybrids is reported. These colloidal LC materials are formed by hybridization of a hydroxyapatite nanorod with azobenzene‐based forklike molecules.

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption
Advanced Functional Materials, EarlyView.Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.
