Auxin response and PIN‐mediated transport in chlorophyte algae

open access: yesJournal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Strong Mode Coupling and Maximum Directional Absorption in Reciprocal Bianisotropic Metasurfaces

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Symmetry breaking in q‐BIC dielectric metasurfaces enables strong electromagnetic coupling between electric and magnetic modes, leading to their hybridization and Rabi‐like splitting. This mechanism produces pronounced reciprocal bianisotropy and dual‐band asymmetric absorption under opposite illumination directions, offering a compact framework for ...

Dramatic and Elusive Resonant Lattice Kerker Effect in the Nonlinear Response of Plasmonic Lattices

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Plasmonic metasurface that supports the resonant lattice Kerker effect, manifesting as the suppression of reflection in a narrow spectral range due to the simultaneous excitation of electric dipole and quadrupole modes, also gives rise to a substantial near‐field enhancement.

Controlling Nanoscale Heat With Optically Coupled Plasmonic Systems

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Optical coupling in plasmonic nanostructures is shown to enable precise spatiotemporal control of nanoscale heat. By engineering near‐field interactions in dimers, trimers, and switchable clusters, thermal energy is asymmetrically distributed, focused into sub‐diffraction volumes, or turned on/off via structural reconfiguration. These design principles

Polyurethane Depolymerization With Alkyl, Aryl, and Mixed Carbonates

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
The depolymerization of polyurethane foams strongly depends on carbonate structure. Aryl carbonates improve hard‐segment solubility but generate side products. Alkyl carbonates give cleaner products yet suffer from limited hard‐block solubility and require anisole as a cosolvent. Mixed carbonate systems balance these effects, improving solubility while

A Low‐Power Cryogenic Low‐Noise Amplifier for the Next‐Generation Quantum Computers

open access: yesphysica status solidi (a), Volume 223, Issue 11, 10 June 2026.
Next generation of quantum computers calls for reduced dc power dissipation of the cryogenic low‐noise amplifier (LNA) applied in reading out the superconducting qubits. This article reports on processing and evaluation of a 100‐nm gate length indium phosphide high electron mobility transistor (InP HEMT) technology used in the design of such LNAs.

Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials

open access: yesAdvanced Materials, Volume 38, Issue 31, 2 June 2026.
Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

Non‐Continuous Iridescent Variable Structural Color Based on Metallic Surface Periodic Structures

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
This study presents an ink‐free laser nanofabrication technique that generates periodic arched microstructures on titanium surfaces, achieving non‐continuous iridescent dual‐color switching. The ridge and side flanks of these structures possess distinct oxide film thicknesses, enabling angle‐dependent selective reflection of specific wavelengths.
