Advanced Functional Materials, EarlyView.Charge carrier concentration and mobility in TiO2, ZrO2, and HfO2 powder films are experimentally mapped as a function of temperature. The results uncover polaron‐mediated transport regimes and field‐activated conduction, enabling the design of oxide‐based electronic and energy devices with thermally tunable functionality.

Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers
Advanced Functional Materials, EarlyView.Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

Aerosol Jet Printed MXene Microsupercapacitors for Flexible and Washable Textile Energy Storage
Advanced Functional Materials, EarlyView.This study introduces a novel approach using aerosol jet printing to fabricate e‐textiles with additive‐free aqueous Ti3C2Tx MXene inks. The flexible electrodes, systematically explored on cotton, polycotton, and polyester, exhibit remarkable areal capacitances of up to 4.4 F cm−2, achieving superior high‐rate performance, capacitance retention, and ...
