Active Particles in Tunable Compressible Environments

open access: yesSmall Science, Volume 6, Issue 5, May 2026.
Gold‐capped active microparticles powered by electric fields plough their way through a matrix of repulsive spheres, shoveling them aside. At high densities and field strengths, an initial strong direction fluctuation may compress the matrix asymmetrically and lead to an asymmetric reaction favoring sustained turns to the same side (spontaneous ...

Merging van der Waals Materials and Optical Metasurfaces for Cavity Quantum Electrodynamics

open access: yesNanophotonics, Volume 15, Issue 5, 16 March 2026.
Flat optical metasurfaces supporting quasi‐bound states in the continuum (qBIC) enable cavity‐like, high‐Q resonances in ultrathin nanostructures. This perspective explores the emergence of cavity quantum electrodynamics in qBIC metasurfaces, specifically those made from ultrathin van der Waals nanostructures, where cavities and emitters are seamlessly

A Partial Element Equivalent Circuit Model of a Permanent Magnet Electrodynamic Suspension

open access: yes2025 IEEE Energy Conversion Conference Congress and Exposition (ECCE)
Permanent magnet electrodynamic suspensions rely on induced currents for the magnetic levitation of transportation systems. To predict these currents and the forces they generate, a partial element equivalent circuit model is presented in this paper. By discretizing the conductive track into a network of interconnected elements, the model is able to ...

Electrochemical Biosensors for Cancer Biomarker Detection: Basic Concept, Design Strategy and Cutting‐Edge Development

open access: yesElectrochemical Science Advances, Volume 5, Issue 5, October 2025.
ABSTRACT Cancer is a result of uncontrolled cell growth with the potential to damage or spread to another part of the body. It is the deadliest disease in the world; therefore, rapid and sensitive detection is essential to fight it. In the past few decades, many diagnosis tools have been developed to detect cancer and monitor therapy progress.
