Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films

open access: yesMacromolecular Rapid Communications, EarlyView.
We measure the optical response of poly[3,4‐ethylenedioxythiophene] thin films through the combination of polarized photon spectroscopies (variable‐angle ellipsometry, UV–mid‐IR reflectance and transmittance) and wide‐angle X‐ray scattering, revealing anisotropic optical response and conductivity and enabling structural modelling of chain and π‐system ...

Excellent Microwave Absorption of Polyurethane Nanocomposites Engineered With Graphene Nanoplatelets and Magnetite

open access: yesJournal of Polymer Science, EarlyView.
Reflection loss behavior and microwave absorption mechanism of graphene nanoplatelet and magnetite reinforced polyurethane nanocomposites, highlighting synergistic dielectric and magnetic losses. ABSTRACT The escalating growth in telecommunication technology has led to a surge in electromagnetic pollution due to the increase in electronic devices. This

A Solventless Melt Route to Polymer/Mixed‐Metal Sulfide Nanocomposites: Case Study on NiCo2S4/PVP

open access: yesJournal of Polymer Science, EarlyView.
Solvent‐free thermolysis of metal (Ni, Co)‐ xanthate precursors in PVP enables the in situ formation of NiCo2S4 nanoparticles embedded within the polymer matrix. ABSTRACT Polymer‐inorganic nanocomposites are commonly prepared using solution‐based approaches that rely on solvents, often toxic or costly, and multi‐step processing, which can limit ...

Optical‐controlled magnon transport based on spin crossover switched molecular magnets

open access: yesSmart Molecules, EarlyView.
A cyanide‐bridged W(V)–Fe(II) spin‐crossover single crystal was integrated into a magnon transport device, enabling reversible optical control of magnon transport through photo‐switched spin states. Abstract Molecule‐based devices that combine the advantages of fast time response and extremely low manipulation/transmission energy consumption of light ...

High‐performance electro‐optic materials featuring enhanced thermal stability through dual‐donor structural crosslinking engineering

open access: yesSmart Molecules, EarlyView.
A groundbreaking dual‐donor crosslinking strategy was reported to significantly enhance the thermal stability, achieving remarkable EO coefficients (257–301 pm/V), glass transition temperatures (Tg) ranging from 107–187°C, and ultrahigh chromophore densities (3.73–4.26 × 10²⁰ molecules/cm³) with exceptional long‐term stability after 500 h at 85°C ...

Strategic Spatial Segregation in Silicon Photoelectrodes: Decoupling Catalytic and Optical Functions for High‐Efficiency Solar Water Splitting

open access: yesSmall Structures, Volume 6, Issue 5, May 2025.
A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...

A Long‐Period Grating Formed by Residual Stress on Thin‐Film Lithium Niobate With Efficient Electro‐Optic and Thermo‐Optic Tuning

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
Three‐dimensional schematic (a) of the proposed long‐period grating (LPG) on thin‐film lithium niobate (TFLN) and its cross‐sectional view (b) showing a TFLN core with a BCB cladding and a periodic metal structure. Residual stress generated at the metal–BCB interface creates the LPG.
