Green Chemistry im Chemieunterricht: eine farbstoffsensibilisierte Solarzelle mit sicheren und leicht verfügbaren Materialien

CHEMKON, EarlyView.
Farbstoffsensibilisierte Solarzellen (Dye‐sensitized Solar Cells, DSSCs) stellen einen biomimetischen Ansatz zur Umwandlung von Sonnenlicht in elektrische Energie dar, der sich am Funktionsprinzip der Photosynthese orientiert. Trotz ihres seit den frühen 1990er‐Jahren bekannten Konzepts existieren bislang nur wenige experimentelle Zugänge, die zugleich

Chlorophyll formation and phytochrome

, 1973
The rôle of phytochrome in the regeneration of protochlorophyll (Pchl) in darkness following short exposures to light, as well as in the accumulation of chlorophyll- a (Chl- a ) in continuous light in previously dark-grown seedlings of pea, bean, and ...

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

Deep 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.

A novel quantitative, sub-provincial approach to characterizing the shape of chlorophyll profiles

, 2001
Bibliography: leaves 122-136.In this study, novel approaches such as artificial neural networks and generalized modelling have highlighted the variability in profile shape and enabled its improved prediction. This will lead to superior regional estimates

Linking species distribution models with population abundance to support adaptive fisheries management

Ecography, EarlyView.
Understanding how environmental variability structures essential fish habitat (EFH) is central to managing keystone populations in dynamic marine ecosystems. Using nearly three decades of standardized survey data (1994–2021) from the Adriatic Sea, we present the first basin‐scale, process‐based framework linking estimated habitat suitability and ...

Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

Model of decomposition of the native absorption spectrum of Porphyridium purpureum culture

Вестник Самарского университета: Естественнонаучная серия
A model of the native absorption spectrum of the red seaweed Porphyridium purpureum culture was developed in this work. The mathematical model of each pigment is the sum of Gaussian curves.
