Surface‐Mounted Metal‐Organic Framework for the Adsorption and Sensing of Monoaromatic Pollutants in Water Using Quartz Crystal Microbalance

Advanced Materials Technologies, EarlyView.
A hydrophobic metal‐organic framework (UHMOF‐100) is grown on a quartz crystal microbalance sensor for the first time. The device enables real‐time, selective detection of monoaromatic BTEX pollutants in water, demonstrating a new strategy for creating robust chemical sensors for challenging environmental monitoring applications.

Hundreds of Nanocoulomb Electron Acceleration Driven by Multipetawatt Laser in Subcritical Density Plasmas

Advanced Photonics Research, EarlyView.
Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Pressure‐Assisted Ceramic Processing of Metal Halide Perovskites

Advanced Photonics Research, EarlyView.
This review critically assesses low‐temperature, pressure‐assisted ceramic processing as a pivotal technique to fabricate dense, polycrystalline wafers with precisely controlled macroscopic dimensions as well as microstructural properties. The aim is to bridge understanding between expert ceramists and halide perovskite specialists, highlighting the ...

Low‐Strain Flexible Ink‐Based Sensors Enable Hyperelastic Inflation Perception Via Geometric Patterning for Balloon‐Type Robots

Advanced Robotics Research, EarlyView.
Integrating proprioceptive capabilities in balloon‐type robots enhances safe human–machine interactions. Traditional pressure estimates are inadequate due to nonlinear relationships. Instead, embedding stretchable sensors effectively measures deformation. This design optimizes sensor geometry to minimize damage risks.
