Near‐infrared confocal imaging reveals the spatial organisation of far‐red photosynthesis in Shark Bay microbial mats and Halomicronema sp.

open access: yesJournal of Microscopy, Volume 304, Issue 3, Page 277-300, December 2026.
Abstract Far‐red light (FRL) cyanobacteria occupy spectrally filtered habitats where visible wavelengths are depleted but far‐red radiation persists. Shark Bay (Western Australia) stromatolitic microbial mats provide such a habitat, containing subsurface cyanobacterial communities in which chlorophyll d/f (Chl d/f)‐containing phototrophs coexist with ...

Towards authentication of beef, chicken and lard using micro near-infrared spectrometer based on support vector machine classification [PDF]

open access: yes, 2016
NIR (near infrared) spectrometer utilized a quick reliable mean of molecular chemical detection. In this paper, we propose a method on authenticating fats originated from beef, chicken and lard. These compositions can be identified by NIR spectrometers

Multiplexed Nanosensors for Real‐Time Monitoring of VOC‐Mediated Signalling Response in Plants

open access: yesPlant, Cell &Environment, Volume 49, Issue 12, Page 9907-9931, December 2026.
ABSTRACT To enhance crop performance, intercropping strategies leverage volatile organic compound (VOC)‐driven interactions with companion plants that constitutively emit VOCs. Despite the agricultural importance, the mechanisms and kinetics of VOC‐mediated sensory transduction in receiver plants eavesdropping on neighbouring non‐kin emitters remain ...

Stable, Reusable Copper‐Bispidine Catalysts on Agarose With Diffusion‐Limited Turnover: When Immobilization is not Covalent

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 31, 3 November 2026.
Epoxy‐activated agarose beads as support for copper(II)‐bispidine complexes provide reusable heterogeneous catalysts for styrene aziridination with negligible copper leaching. Immobilization occurs largely through noncovalent interactions. Catalyst loading strongly governs performance by balancing active‐site density, accessibility, and mass transport.

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

open access: yesAdvanced Functional Materials, Volume 36, Issue 89, 5 November 2026.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

TH17–Associated Polyamine Metabolism‐Guided Nanozyme Promotes Alveolar Bone Repair in Periodontitis

open access: yesAdvanced Science, Volume 13, Issue 62, 9 November 2026.
A pronounced TH17‐skewed immune response is identified in experimental periodontitis, and enrichment of the polyamine pathway is observed during TH17 differentiation, suggesting its potential as an immunometabolic target. Inspired by these findings, DFMO@Ui‐Mn is developed as a therapeutic platform combining cascade ROS scavenging with immunometabolic ...

Maximum Stability Point Tracking Stabilizes Wide‐Bandgap Mixed‐Halide Perovskite Solar Cells

open access: yesAdvanced Energy Materials, Volume 16, Issue 41, 4 November 2026.
A maximum stability point tracking (MSPT) strategy suppresses charge trapping‐induced halide segregation, enabling wide‐bandgap perovskite solar cells to achieve significantly enhanced operational stability compared to conventional maximum power point tracking (MPPT).
