CeO2‐Based Electrocatalysts for the Oxygen Evolution Reaction: Design, Dynamic Mechanisms, and Electrolyte Adaptability

Advanced Science, EarlyView.
This Review shows how cerium oxide helps water‐splitting catalysts work better and last longer. It explains how CeO2 tunes electronic structure, oxygen‐vacancy behavior, and surface reconstruction, while adapting to alkaline, acidic, and seawater conditions.

Sulfur isotopes from the Paleoproterozoic Francevillian Basin record multigenerational pyrite formation, not depositional conditions

Communications Earth & Environment
Bulk-rock sulfur isotope data from pyrite in the ~2.1 billion-year sedimentary rocks of the Francevillian Basin, Gabon, have underpinned ideas about initial oxygenation of Earth’s surface environments and eukaryote evolution.

Wine and Grape Tannin Interactions with Salivary Proteins and Their Impact on Astringency: A Review of Current Research

Molecules, 2011
Astringency is an important characteristic of red wine quality. The sensation is generally thought to be produced by the interaction of wine tannins with salivary proteins and the subsequent aggregation and precipitation of protein-tannin complexes.

Toward Sustainable Smart Packaging: Demonstration of Laser‐Induced Graphene Sensors on Orange‐Based Substrates

Advanced Electronic Materials, EarlyView.
Orange peel waste is directly transformed into biodegradable bioplastic films and converted into electronically active laser‐induced graphene (LIG) sensors through single‐step 450 nm laser scribing. Without requiring conductive inks, metallic coatings, or transfer steps, localized photothermal conversion creates porous 3D graphitic networks with sheet ...
