Synthesis of a π‐Extended Phenazine Diimide Derivative and Characterization of Its Closed‐Shell Reduced States

open access: yesChemistry – A European Journal, EarlyView.
In this work, the synthesis and characterization of novel π‐extended phenazine diimides is reported. The derivatives undergo differential reduction to a dihydrophenazine or Meisenheimer form depending on the reaction conditions employed. The outcome of this work highlights the paramount importance of structural design in determining the nature of the ...

Photoelectrochemical Hydrogen Peroxide Production via Simultaneous Reduction and Oxidation Processes

open access: yesChemistry – A European Journal, EarlyView.
Hydrogen peroxide (H2O2) is an important chemical substance and also a promising carbon‐free clean fuel. The design of a sophisticated photoelectrochemical (PEC) reaction system enables the solar‐driven H2O2 production through simultaneous water oxidation and oxygen reduction processes (H2O2/H2O2‐PEC cells).

Mimicking The Photosynthetic Special Pair With Aluminum(III) Porphyrin Homodimer – Fullerene (C60) Supramolecular Assemblies Capable of Long‐Lived Charge Separation

open access: yesChemistry – A European Journal, EarlyView.
The axial‐bonding of aluminum(III) porphyrins was used to create two covalently linked special‐pair mimics to probe charge‐transfer between a porphyrin dimer and a C60 unit for artificial photosynthesis. Although excitonic coupling between the porphyrins is weak, incorporation of a second porphyrin markedly increases both the yield and lifetime of the ...

Photocatalytic Oxygen Evolution with Prussian Blue Coated ZnO Origami Core‐Shell Nanostructures

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Prussian Blue and its derivative hold significant potential for photocatalytic oxygen evolution. IN this contribution the photocatalytic oxygen evolution reaction (OER) was characterized using a hybrid catalyst consisting of Prussian Blue coated ZnO nanostructures. The resulting heterojunction, which was characterized both structurally and functionally,

High atmospheric pressure rescues plant growth under humidity stress: A model for climate‐resilient deep underground agriculture

open access: yesDeep Underground Science and Engineering, EarlyView.
High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.

Boosting Charge Separation in a CdIn2S4/Mo2TiC2 MXene Schottky Heterojunction for Enhanced Photocatalytic Hydrogen Production

open access: yesEcoEnergy, EarlyView.
ABSTRACT Mo2TiC2 MXene was exfoliated in situ using hydrofluoric acid solution and subsequently integrated with CdIn2S4 through physical stirring and grinding. The composite material demonstrated exceptional photocatalytic hydrogen evolution (PHE) activity without the loading of any noble metal co‐catalysts, achieving a hydrogen production rate as high

‘MultiTraits': an integrated R package for analysis and visualization of multidimensional plant traits

open access: yesEcography, EarlyView.
The multidimensional characteristics of plant traits and their trade‐offs are central to ecology. However, there is a lack of systematic and standardized tools for analyzing these intricate relationships. To fill this gap, we developed the ‘MultiTraits' R package, which incorporates four complementary analytical modules: competitors–stress tolerators ...

Environmental heterogeneity and spatial variation mediates plant diversity and ecosystem stability in mountain ecosystems of the Mediterranean Andes

open access: yesEcography, EarlyView.
Globally, mountains are highly diverse ecosystems that serve as natural laboratories for testing ecological theories, while providing vital ecosystem services. Their biodiversity arises from the interaction between elevational gradients and topographic complexity, which generate strong variation in environmental conditions across short spatial scales ...
