High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands

Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
E/O modulators typically face a trade‐off between bandwidth and modulation efficiency. An integrated E/O modulator is presented that simultaneously achieves wideband, large bandwidth, and high modulation efficiency operation by embedding a partially overlapped double‐layer graphene on a compact silicon slot‐waveguide microring resonator.

Femtosecond‐Laser‐Inscribed Cladding Fiber Bragg Gratings: Architectures, Design Trade‐Offs and Future Sensing Opportunities

Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
Femtosecond‐laser inscription enables precise positioning of fiber Bragg gratings within the cladding, introducing new spatial and modal design freedoms. Auxiliary‐waveguide, near‐core evanescent‐field, and direct cladding‐mode‐excitation architectures provide complementary pathways toward multiparameter, vector, distributed, and environmentally ...

Modular Metalloprotein Nanowires With Semiconductor‐Scale Conductivity and Tunable Redox Behavior

Small Structures, Volume 7, Issue 10, October 2026.
Conductive protein nanowires are built by aligning three different metalloproteins along an ultrastable filament scaffold. The resulting micrometer‐length nanowires reach conductivities of 1.75 S cm−1. Redox behavior is set by the metalloprotein chosen, while conductivity is governed by the spacing the scaffold imposes, making both independently ...

Unripe Banana Genotypes are Starchy Sources. Part I. Morphology, Growth Rings, and Ultrastructure of Native Starches

Starch - Stärke, Volume 78, Issue 10, October 2026.
Unripe banana flour is a starch source with a high content of resistant starch in its raw form. Recently, interest has grown in raw materials with low levels of indigestible carbohydrates. Different banana genotypes vary in granule morphology, which influences their functional properties and digestibility.

ATP Release and Purinergic Signaling Potentiate β‐Adrenergic Effects on Brown Adipocytes

Acta Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim Brown adipose tissue (BAT) specializes in energy consumption and thermogenesis in response to cold stress. Brown adipocytes (BA) express purinergic receptors, yet little is known about the source of extracellular ATP and the role of purinergic signaling, and the potential interaction with β‐adrenergic signaling.

Design of an extra-low-loss broadband Y-branch waveguide splitter based on a tapered MMI structure

An optimal design for an extra-low loss buried waveguide Y-branch splitter is presented over a broadband wavelength range from 1500~1600 nm. A tapered multimode waveguide section, earlier used to reduce the excess loss, is optimized when the light ...

Lysin Motif Effectors Facilitate the Endophytic Colonization of Wheat by Sclerotinia sclerotiorum via Modulating Plant Immunity

Molecular Plant Pathology, Volume 27, Issue 10, October 2026.
Two LysM effectors of Sclerotinia sclerotiorum are essential for the endophytic colonization of wheat. SsLysM6/7 inhibit chitin‐induced immune responses and undermine wheat immunity to promote fungal growth. ABSTRACT Sclerotinia sclerotiorum is a necrotrophic fungus that causes severe plant diseases but can also colonize wheat as a symptomless ...

Influence of Beam Profile and Fiber‐to‐Device Separation on Segmented GaAs Photovoltaic Power Converters

Solar RRL, Volume 10, Issue 17, 15 September 2026.
Beam shaping in segmented GaAs photovoltaic power converters is investigated using quasi‐Gaussian and annular illumination profiles from a double‐clad fiber. The findings show that beam profile and fiber‐to‐device separation govern voltage, fill factor (FF), and conversion efficiency.
