Impact of Seasonal Variation on Antioxidant, Enzyme Inhibitory, and Anti‐Inflammatory Potentials of Cistus creticus Leaf Extracts

open access: yesChemistryOpen, EarlyView.
The phytochemical profile and biological activities of Cistus creticus leaf ethanolic extracts show strong seasonal variation. Spring extracts contain the highest phenolic levels with potent antioxidant and anti‐inflammatory effects, while summer extracts are richest in flavonoids and exhibit the greatest sun protection factor value and enzyme ...

Enhancing the Oxygen Evolution Performance by Introducing NiO‐Supported Mesoporous Titanium Dioxide

open access: yesChemistryOpen, EarlyView.
Herein, a schematic representation of the synthesis of NiO‐supported mesoporous TiO2 is reported. The process involves self‐assembly of polyvinylpyrrolidone (PVP), Ti(acac)2, nickel salt, and ethanol, followed by solvent evaporation, thermal polymerization, and stepwise calcination under N2 (350 °C) and air (450 °C) to remove PVP and carbon, yielding ...

The importance of wild meat and freshwater fish for children's nutritional intake in the Congo Basin

open access: yesPeople and Nature, EarlyView.
Abstract Wild meat and freshwater fish are widely consumed in the Congo Basin, but in some areas, they are at risk of disappearing due to unsustainable hunting and fishing and changes in their habitat. Wild meat is also at risk of being eliminated from local diets due to potential policy changes such as wild meat bans.

A biodegradable polylactic acid–polybutylene adipate terephthalate–starch polymer blend for geotextile applications

open access: yesPolymer International, EarlyView.
Biodegradable polymer blends are environmentally friendly materials with the ability to tailor material properties according to requirements. Abstract Geotextiles are typically used to stabilize steep earthen structures to prevent landslides. Usually, such geotextiles are made from petrol‐based polymers (such as polypropylene), but the use of ...

Sample Preparation for Multi‐Omics Analysis: Considerations and Guidance for Identifying the Ideal Workflow

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Advances in methodologies and technologies over the past decade have led to an unprecedented depth of analysis of a cell's biomolecules, with entire genomes able to be sequenced in hours and up to 10,000 transcripts or ORF products (proteins) able to be quantified from a single cell.

Double Gyroid‐Forming Hybrid Anion Exchange Membranes With Superior Mechanical Properties

open access: yesJournal of Polymer Science, EarlyView.
Gyroid‐structured hybrid anion exchange membranes with enhanced mechanical properties were produced by infiltratingsilica precursors within the block copolymer nanochannels. ABSTRACT Nanostructured hybrid anion exchange membranes (AEMs) with enhanced mechanical properties were fabricated by first applying a solvent vapor annealing (SVA) treatment to a ...

Surface Engineering of Ti3C2Tx MXenes via Silanol Functionalization for Improved Electrochemical Performance

open access: yesSmall, EarlyView.
This study explores the covalent functionalization of Ti3C2Tx using 5,5′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine in different solvents, revealing that only m‐xylene enables effective covalent bonding, ensuring structural stability and preventing layer swelling.
