Elastomeric 3D‐Printed Microenvironments Enable Nanonewton Force Measurements in Healthy and Diseased Human Pluripotent Stem Cell‐Derived Neuroepithelial Cells

open access: yesAdvanced Materials, EarlyView.
We present elastomeric three‐dimensional (3D) microstructures fabricated via two‐photon polymerization (2PP) and post‐processed through wet etching, for quantifying nanonewton (nN)‐scale forces applied by healthy and diseased neural cells. The mechanically characterized free‐standing beam architectures enable measurement of traction forces of ...

S‐Nitrosothiols as Thiol‐Protecting Groups for Controlled Thiol‐Maleimide Crosslinking of Homogeneous Soft Hydrogels

open access: yesAdvanced Materials, EarlyView.
Rapid thiol‐maleimide addition frequently outpaces mixing, resulting in heterogeneous hydrogels. S‐nitrosothiols act as thiol‐protecting groups, allowing uniform mixing with maleimide‐functionalized polymers before gelation. Sodium thiosulfate or sodium ascorbate then regenerates thiols on demand, triggering controlled thiol‐maleimide crosslinking ...

TESCLA: A Fully Soft Electromagnetic Linear Actuator With Continuous Bending Enabled by Liquid‐Metal Solenoids

open access: yesAdvanced Materials, EarlyView.
TESCLA (tubular electromagnetic soft conformal linear actuator) combines liquid‐metal solenoids and compliant magnetic composites to achieve large‐stroke bidirectional actuation with continuous bending. Integrated inductance‐based self‐sensing enables proprioceptive position estimation without external sensors, providing a versatile platform for soft ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Bandgap‐Dependent Band‐to‐Band Tunneling in Carbon Nanotube Transistors

open access: yesAdvanced Materials Interfaces, EarlyView.
We systematically investigate bandgap‐dependent BTBT in SWCNT transistors by comparing wide‐bandgap (6,5) (Eg≈1.13 eV), medium‐bandgap HiPco, and narrow‐bandgap Arc‐discharge (Eg≈0.59 eV) SWCNT networks. The narrow‐bandgap networks show stronger BTBT, higher off‐state leakage, and lower on/off ratio, while wide‐bandgap (6,5) devices suppress BTBT and ...

Fabrication of TiN/TiO2 Nanotube‐Based Heterostructure for Hydrogen Sensing Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
A hydrogen sensor based on titanium dioxide nanotubes coated with titanium nitride has been developed. The coating process causes a mixed titanium oxynitride layer to form, which improves the sensor performance. Sensor response R depends on the TiN thickness and is not degraded after 7 days in air.

Conjugated Metal‐Organic Frameworks on Laser‐Induced‐Graphene Scaffold Enable Picomolar Sensitivity in Electrical Biosensors

open access: yesAdvanced Materials Interfaces, EarlyView.
A controlled layer‐by‐layer growth process integrates conjugated metal‐organic framework thin films onto a hierarchical 3D laser‐induced graphene scaffold. When incorporated into an extended‐gate field‐effect transistor configuration, this synergistic hybrid platform achieves robust aptamer immobilization, driving highly selective, picomolar‐level ...
