Also fully Open Access now our article "Carbon nanomaterials-Based Inks and Electrodes Using Chitin Nanocrystals",
ACS Sustainable Chemistry & Engineering 2024, 12, 15980-15590:

Dispersing 1D carbon nanomaterials (CNMs) for film processing traditionally relies on surfactants or organic solvents. These methods, however, raise environmental concerns and can negatively impact the final properties of the CNMs. In this work we demonstrate that chitin nanocrystals (ChNCs) synthes...

Contributing to sustainable device components, it's great to see our work on "Carbon nanotube film electrodes enabled by nanostructured biopolymers through aqueous processing" being published in PCCP. It's freely available under https://doi.org/10.1039/d5cp01536g. Enjoy reading.

Processing carbon nanotubes (C**s) into conductive films via liquid-phase is highly attractive for the fabrication of electronic and electrochemical device components. However, conventional deposition methods usually suffer from several limitations, including environmental concerns, loss of intrinsi...
