New Labor Governance? The German Supply Chain Act and National Governance Mechanisms in Brazil

open access: yesRegulation &Governance, EarlyView.
ABSTRACT Due diligence laws respond to labor governance challenges and to a lack of public governance addressing human rights violations in Global Value Chains. Despite ongoing contestation, the German Supply Chain Due Diligence Act seeks to hold German‐based firms accountable for human rights risks in their supply chains.

Electrophysiological properties of the dorsal motor nucleus of the vagus motoneurones controlling airway mucus secretion in rats

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Acidosis depolarises parasympathetic respiratory motoneurones in the dorsal motor nucleus of the vagus (DMV) and increases their firing frequency by reducing TWIK‐2 channel conductance. Acidosis also activates astrocytes, which further enhance neuronal excitability through NMDA receptor‐dependent glutamatergic signalling.

Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

open access: yesNew Phytologist, Volume 252, Issue 1, Page 69-86, October 2026.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

Directly Imprinted Porous Titania Metasurfaces Supporting Guided Mode Resonance and Quasibound States in the Continuum

open access: yesAdvanced Photonics Research, Volume 7, Issue 9, September 2026.
Direct nanoimprinting transforms mesoporous titania films into visible‐wavelength metasurfaces through a streamlined deposition‐and‐imprint process requiring no conventional lithography or etching. The resulting structures support pitch‐tunable guided‐mode resonances, symmetry‐controlled quasibound states in the continuum, structural‐color image ...

Liquid‐phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 5, Page 2096-2105, September/October 2026.
Abstract Oxidation of furfural (FF), a bio‐based platform chemical, was investigated using a range of iron‐, vanadium‐ and iron–zinc‐oxalates supported on silica gel (FeVOx@silica and FeZnOx@silica, respectively) as precursor for FeV@silica and FeZn@silica oxide catalysts and H2O2 as a green oxidant.

Bacterial Cyclodipeptides Target Signal Pathways Involved in Malignant Melanoma

open access: yesFrontiers in Oncology, 2020
Melanoma is an aggressive cancer that utilizes multiple signaling pathways, including those that involve oncogenes, proto-oncogenes, and tumor suppressors. It has been suggested that melanoma formation requires cross-talk of the PI3K/Akt/mTOR and Ras-ERK
