Effect of pyrolysis conditions on chemical properties of carbonized rice husks for efficient NH4 + adsorption

Applied Biological Chemistry, 2023
Ammonium ions (NH4 +) are commonly found in contaminated water and are a contributing factor to water eutrophication. Carbonized rice husk, derived from various biomass sources, possesses a porous structure, and its characteristics are influenced by the ...

Graphene Layers as Functional Biomaterials. From Fabrication and Characterization to Biological Applications

Advanced Materials Interfaces, EarlyView.
Graphene layers are fabricated on Cu foil and transferred onto glass substrates to form double‐ and multi‐layer G‐glass. Raman spectroscopy confirms structural integrity, while SEM and fluorescence microscopy reveal favorable adhesion and spreading of L‐929 fibroblast cells.
