Dynamic Multifunctional Metasurfaces Based on Passive Cascade Structure

Electron, Volume 4, Issue 2, May 2026.
A dynamic multifunctional metasurface is proposed in this paper. Unlike mainstream multifunctional metasurface based on programmable metasurfaces, it consists of two passive metasurfaces, presenting a significant cost advantage. By controlling the displacement, different functions such as beam steering, focusing, and OAM wave generation can be realized

Cell Mechanics in Cancer: Integrating Mechanotransduction Pathways Within the Tumor Microenvironment

Journal of Cellular Physiology, Volume 241, Issue 5, May 2026.
ABSTRACT Single‐cell mechanical properties such as stiffness, elasticity, and viscosity, are crucial in governing biological processes like migration, proliferation, and differentiation. In cancer, the mechanical properties of cells undergo significant alterations, which contribute to tumor growth, metastasis, and resistance to therapy.

Reducing the Threshold of Organic Polariton Lasers by Active Layer Micropatterning and Lateral Confinement

Small Structures, Volume 7, Issue 5, May 2026.
The study demonstrates the miniaturization of organic polariton VCSELs based on BSBCz. Using ultra‐thin shadow masks, isolated microcavities as small as 5 µm are fabricated. These devices achieved record‐low lasing fluences (0.21 µJ/cm2), far below reference devices.
