Oil Encapsulation in Core–Shell Filaments from Cellulose Nanocrystals and Methylcellulose via Dry-Jet Wet Spinning

Abstract The incorporation of oils into structured and water-compatible materials remains a key challenge for cellulose-based materials. Here, we demonstrate the production of core–shell filaments from cellulose nanocrystals (CNCs) and methylcellulose (MC) via a dry-jet wet spinn...

Wildfire-Derived Biomass as a Feedstock for Activated Carbon Production: Characterization, Heavy Metal Adsorption, and Preliminary Environmental and Economic Assessment

Wildfires burned an average of about 7 million acres per year in the United States between 2000 and 2025, more than twice the annual rate of the 1990s. The woody residue left behind is largely unmanaged. At the same time, heavy-metal contamination of drinking water by lead, cadmi...
