Characterization and Selection of Contractile Actuators for Soft Robotics Operating in the Quasistatic Regime

Advanced Intelligent Systems, EarlyView.
We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

Kinetic Theory of Self-Propelled Particles with Nematic Alignment

Entropy
We present the results from kinetic theory for a system of self-propelled particles with alignment interactions of higher-order symmetry, particularly nematic ones. To this end, we use the Landau equation approach, a systematic approximation to the BBGKY

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Flexible Direct‐Conversion X‐Ray Detectors: From Emerging Materials to Conformal Imaging

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This comprehensive review analyzed the performance, challenges, and future directions of four emerging material systems for next‐generation flexible direct‐conversion X‐ray detectors: organic semiconductors, perovskites, metal–organic frameworks, and inorganic metal compounds.

The importance of being discrete: fluctuations, defects, and density-orientation coupling in agent-based active nematics

New Journal of Physics
We propose an agent-based model of active flexible rods. Inspired by cytoskeletal flows, we introduce activity by an internal flow that contributes to the dissipative forces.

Illuminating point‐of‐care diagnostics with aggregation‐induced emission biosensors

FlexMat, EarlyView.
This review highlights the application of aggregation‐induced emission luminogens (AIEgens) in point‐of‐care (POC) diagnostics for disease biomarker detection. It systematically examines a range of biosensing platforms, including lateral flow immunoassays, microfluidic chips, and electrochemiluminescence sensors, alongside their utility in detecting ...

Pancharatnam–Berry Phase Driven by Electrical Restructuring of Liquid Crystal Polarization Grating Period

Laser &Photonics Reviews, EarlyView.
Electrically controlled liquid‐crystal twist diffraction element based on the Pancharatnam–Berry phase enables switchable structural periodicity and simultaneous generation of orthogonal circularly polarized coherent waves for multifunctional planar photonic devices.

Shaping Liquid Crystal Rubbers by Chemical Potential Gradient

Macromolecular Rapid Communications, EarlyView.
Depositing a low molecular weight liquid crystal drop onto a uniformly aligned LCE leads to non‐uniform swelling, enabling temporary shape changes and bending actuation. These deformations are quantitatively modeled for different alignment conditions, and methods to permanently lock desired shapes are explored.

Photo‐Switched Catalytic Amyloids

Small, EarlyView.
Photo‐switched reversible hierarchical assembly of catalytic amyloid fibrils is accomplished by mixing an amphiphilic cross‐ß peptide with a merocyanine photo switch. The peptide monomers, comprising phenylalanine‐lysine repeats, do not self‐assemble in water because of the electrostatic repulsion.
