Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

open access: yesAdvanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Tunable Sensitivity in PAN/CNF/PEDOT:PSS Nanofiber‐Based Piezocapacitive Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates highly tunable, flexible pressure sensors made from a nanofibrous composite of polyacrylonitrile (PAN) and carbon nanofibers (CNF) or poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS). By adjusting filler type, concentration, and mat thickness, the sensors achieve large sensitivity improvements, stable ...

Room Temperature Synthesis and Photopatterning of Mesoporous Titanium Dioxide Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
A nanofabrication strategy combining deep‐UV photolithography with block copolymer self‐assembly enables direct patterning and mineralization of mesoporous TiO2 thin films at room temperature. Photocatalytic titanium oxo‐clusters promote polymer degradation under UV irradiation, enabling multiscale control over porosity, film thickness, and lateral ...

Precipitation and plant community-weighted mean traits determine total transpirable soil water in a desert grassland

open access: yesEcological Indicators
The desert grassland has low precipitation, high evaporation and a limited soil water supply. Thus the tension between water shortage and sustainable vegetation restoration is increasingly evident.

Mitochondria‐Specific Protein Delivery by Protease‐Triggered Release in Plants with Single‐Walled Carbon Nanotubes

open access: yesAdvanced Materials Technologies, EarlyView.
Polymer‐coated carbon nanotubes were engineered as protease‐responsive nanocarriers for protein delivery in intact plants. GFP cargo can be released by cytosolic phytaspase cleavage and subsequently targeted to mitochondria via an N‐terminal sequence, enabling controlled intracellular protein delivery without tissue damage and demonstrating stable ...

Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs

open access: yesAdvanced Optical Materials, EarlyView.
The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.
