Electrochemical and Biological Evaluation of Patterned TiO2@TiC‐Nanowires for Bio‐Interface Electrode

Small, EarlyView.
This study introduces a room‐temperature process to fabricate patterned TiO2@TiC core–shell nanowires, merging the biocompatibility of TiO2‐NWs with the high conductivity of TiC. Through sputtering pressure and time modulation, the nanowires morphology and electrochemical properties are tuned, enabling enhanced capacitance, stability, and guided ...

Self‐Assembly of Hierarchically Structured Materials From Liquid Crystalline Mesophases of Tobacco Mosaic Virus‐Like Particles

Small, EarlyView.
Recombinantly produced Tobacco Mosaic Virus coat protein (TMVcp) helical rods were demonstrated to reproducibly self‐assemble into hierarchically structured macroscopic filaments, driven by a lyotropic liquid crystal (LC) intermediate phase. The results indicate anisotropic molecular alignment of the fluid phase, retention of the native secondary ...

Near‐White Circularly Polarized Luminescence by Color Mixing Utilizing Surface‐Fluorophore‐Modified Cellulose Nanocrystals in Composite Films

Chemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.
Robust, bio‐derived, and freestanding films based on cellulose nanocrystals (CNCs), covalently decorated with achiral fluorophores, transduce shape chirality and supramolecular helicity into near‐white circularly polarized luminescence (CPL). With composites covering the visible spectrum, near‐white, right‐handed CPL with high luminescence dissymmetry (

Low‐Complexity Phase–Transition‐Based VO2 Transmissive Reconfigurable Intelligent Surface for Indoor Millimeter‐Wave Communications

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
We demonstrate a VO2‐based transmissive reconfigurable intelligent surface for indoor millimeter‐wave communication. The TRIS replaces conventional PIN and varactor diodes with geometrically tailored VO2 switches, enabling transmitted phase control through phase‐transition‐based switching.
