Shaping research in marine functional connectivity for integrated and effective marine science and management

open access: yesBiological Reviews, EarlyView.
ABSTRACT Effective knowledge of ecological connectivity at sea and at the land–sea interface is key to supporting global policy goals to conserve and restore ocean biodiversity and function. However, a persistent lack of commonality in terminology and understanding around the concept of connectivity in marine ecological studies hampers its integration ...

Synthesis and Photophysical Characterization of Axially Functionalized Silicon(IV) Naphthalocyanines with Phototheranostic Potential

open access: yesChemistryEurope, EarlyView.
In this study, the synthesis and detailed photophysical characterization of SiNcs functionalized with structurally diverse axial ligands designed to enhance solubility and evaluate photophysical properties are reported. The lead compound, SiNc 3‐PP, demonstrates photothermal conversion efficiency of 62.1% and pronounced photoacoustic contrast at 810 nm,

Induced‐Fit Recognition by a Calixarene–Pyrene Conjugate for Single‐ and Dual‐Wavelength Fluorescence Sensing in Water

open access: yesChemistry – A European Journal, EarlyView.
A sulfonatocalix[4]arene–pyrene conjugate functions as a fluorescence chemosensor for the optical detection of biorelevant analytes in water. Its photoinduced electron transfer (PET) response is triggered by an induced‐fit recognition mechanism. Noncovalent assembly with an additional dye affords dual‐color ratiometric signaling via competitive PET ...

Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.
