Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis

open access: yesAdvanced Materials, EarlyView.
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Phase‐Change Solvents for Thermally Switchable Ion Conduction in Organogels

open access: yesAdvanced Materials, EarlyView.
Organogels containing salts dissolved in phase‐change solvents exhibit thermally switchable ion conduction. The organogels, which display an over 10 000‐fold on‐off ratio and high cycling stability, can be synthesized with a wide range of salts and customizable conductivity/temperature relations for applications in ionotronics and energy storage ...

Ultrafast Electric Switching of Brookite TiO2 Nanorods with a Permanent Dipole Moment at High Concentrations

open access: yesAdvanced Materials Interfaces, EarlyView.
Brookite titania nanorods dispersed in apolar liquid are found to possess a large permanent dipole moment. Even at high concentration, their orientations can be switched rapidly with an electric field to induce birefringence. This makes these dispersions promising for fast optical switching.

Local Surface Potential Modification of Few‐Layer MoS2 Via Optical Soldering Induced n‐Doping Process

open access: yesAdvanced Materials Interfaces, EarlyView.
We examine surface potential changes in optical soldering induced defect structures of few‐layer MoS2 using Kelvin probe microscope (KPFM). Surface potential measured by KPFM reveal that optical soldering induces n‐doping effect in few‐layer MoS2 with Fermi level shift toward conduction band edge.
