Hydrodynamic Spinning of Protein Fractal Aggregates into Core–Shell Fibers

Using fractal protein aggregates as building blocks, porous fibers were produced. The suspension of aggregates was coinjected with a solution of calcium chloride. Sol–gel transition of the suspension was induced by diffusion of calcium ions in the jet. The production…

Nanoplastic in the North Atlantic Subtropical Gyre

Identification of nanoplastics in complex environmental matrices remains a challenge. Despite the increase in nanoplastics studies, there is a lack of studies dedicated to nanoplastics detection, partially explained by their carbon-based structure, their wide variety of composition, and their low…

Nanoporous hydrogel absorbent based on salep: Swelling behavior and methyl orange adsorption capacity

This study used the gas-blowing method to develop a nanoporous hydrogel using poly (3-sulfopropyl acrylate-co-acrylic acid-co-acrylamide) grafted onto salep. The synthesis of the nanoporous hydrogel was optimized by various parameters for maximum swelling capacity. The nanoporous hydrogel was characterized using…
