Extending Field Limits in Nanoscale Magnetic Imaging With Metamaterial‐Inspired Magnetic Flux Concentrators

open access: yesSmall, Volume 22, Issue 43, 3 August 2026.
Micrometer‐sized flower‐shaped metamaterial magnetic flux concentrators are fabricated directly around nano and micromagnetic samples, enabling local field enhancement. Integrated into magnetic sensitive photoemission electron microscopy, they extend the available magnetic field range by up to a factor of five.

Photon Recycling–Driven Photodetection Enhancement in Ni(AcO)2–MAPbBr3 Nanocomposite Waveguides

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
Photon recycling is demonstrated as an effective mechanism to enhance perovskite photodetector performance. A Ni(AcO)2/MAPbBr3 nanocomposite waveguide enables long‐range propagation and reabsorption of photoluminescence photons, increasing photocurrent by ∼60%. Under pulsed excitation, reabsorption of amplified spontaneous emission further enhances the

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

open access: yesLaser &Photonics Reviews, Volume 20, Issue 13, 8 July 2026.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

Dynamic Interfacial Chemistry of Choline Chloride as Electrolyte Additive for Stable Zn‐Iodine Batteries

open access: yesAdvanced Functional Materials, Volume 36, Issue 52, 29 June 2026.
Choline chloride (ChCl) additive enables dynamic interface engineering in Zn‐I2 batteries by forming hydrophobic polyiodide complexes and a Zn‐stabilizing Ch+‐rich layer under electric field modulation. This dual‐function strategy suppresses iodine hydrolysis and dendrite formation, while optimizing Zn2+ solvation and transport for high‐efficiency ...

Tailoring the Anomalous Nernst Effect of Co/Pt Multilayers Grown on Strained Flexible Substrates

open access: yesAdvanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
Strain engineering offers a powerful approach to enhance the Anomalous Nernst Effect in flexible Co/Pt multilayers. This study demonstrates a 30% thermoelectric improvement under mechanical strain, directly attributed to the modulation of intrinsic interfacial interactions.

Thermal Conductivity and Tunable Thermal Anisotropy of Magnetic CrSBr Monolayer

open access: yesAdvanced Physics Research, Volume 5, Issue 6, June 2026.
Top (left) and side view of single‐layer CrSBr (right). Phonon transport is strongly anisotropic, with a lattice thermal conductivity along the a‐lattice vector which is almost twice the one along the b‐vector (κxx$\kappa _{xx}$ = 1.8 κyy$\kappa _{yy}$). ABSTRACT We present first‐principles calculations of the thermal conductivity, κ${\bm \kappa }$, of

From Sparse Nanoparticles to Graded Interfaces: Beyond Classical Descriptions of LiF Growth on Organic Semiconductors

open access: yesChemistry – An Asian Journal, Volume 21, Issue 12, 26 June 2026.
LiF grows on diindenoperylene not as a smooth film but as sparse, inhomogeniety associated nanoparticles that evolve stochastically toward full coverage, perturbing the interface while leaving the organic lattice intact. ABSTRACT Small‐molecule π$\pi$‐conjugated semiconductors provide an ordered platform for probing interfacial mechanisms in organic ...
