Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Directed Charge Transfer‐Driven Efficient Photocatalytic Hydrogen Production in Dual S‐Scheme WS2/Co9S8/ZnCdS Heterojunction

Carbon Energy, EarlyView.
The photocatalytic hydrogen evolution reaction (HER) activity of the polyoxometalate (POM)‐derived dual S‐scheme heterojunction photocatalyst WS2/Co9S8/ZnCdS reaches a value as high as 15.66 mmol g−1 h−1 under visible light (λ ≥ 420 nm), providing a straightforward approach for the development of dual S‐scheme heterojunctions to enhance the efficiency ...

Design of a Fluorescent Boronic Acid‐Functionalized Pyranoflavylium Receptor to Host and Release Diol‐Rich Bioactive Analytes in a pH‐Dependent Manner

ChemFoodChem, EarlyView.
This work presents a pH‐responsive ON–OFF fluorescent system based on a novel pyranoflavylium dye functionalized with a boronic acid receptor. The receptor exhibits a markedly higher affinity for the catechol‐containing polyphenol (+)‐catechin than for conventional diol‐rich molecules such as glucose and lactic acid.

Formation and Characterization of Insoluble Anthocyanins‐λ‐carrageenan Biopolyelectrolyte Complexes: Structural Morphology, Thermal Stability, and Release Dynamics

ChemFoodChem, EarlyView.
Insoluble biopolyelectrolyte complexes formed between blackberry anthocyanins and λ‐carrageenan are investigated. Optimal complexation occurs at low carrageenan ratios and acidic pH, producing porous hydrogel‐like structures with enhanced thermal stability.
