Electrochemical Sensor Based on Black Phosphorus for Antimony Detection Using Dip‐Pen Nanolithography: The Role of Dwell Time

Small Methods, EarlyView.
Meta‐chemical surfaces based on black phosphorus (BP) are developed for electrochemical Sb(III) sensing using dip‐pen nanolithography. The surface‐to‐volume ratio and the fill factor, which can be altered by the dwell time, affect the detection limit.

The TissueTractor: A Device for Applying Large Strains to Tissues and Cells for Simultaneous High‐Resolution Live Cell Microscopy

Small Methods, EarlyView.
Mechanical strain influences tissue development, homeostasis, and disease. The TissueTractor, a high‐strain stretcher system, enables high‐resolution imaging of live tissues and cells under strain, revealing cellular strain heterogeneity, cytoskeletal remodeling, and morphological adaptations in various model systems.

Structural and Optical Properties of a 0D Lead Iodide Hybrid Perovskitoid with Aromatic Diammonium Cations

Small Structures, EarlyView.
A new 0D hybrid lead iodide perovskitoid with 3‐(aminomethyl)pyridinium) (3AMPy) as organic cation is reported. Its orthorhombic crystal structure consists of isolated [PbI6]4− octahedra, giving rise to vibrational modes with preferential crystal orientation and birefringence.

Adaptive Electromagnetic Manipulation via Smart Metasurface with Ultrasonic Spatial Sensing

Small Structures, EarlyView.
The authors present a smart metasurface platform capable of sensing multiple spatial parameters and manipulating electromagnetic waves adaptively based on external object status. Many interesting functions can be achieved, including automatic beam collimation, adaptive beam broadening, and object recognition and cloaking.
