The cover image shows a transmission electron micrograph of CaCO3 nanoparticles derived from chicken eggshell using a combination of mechanochemical and sonochemical techniques by Tarig Hassan, Vijaya Rangari, and Shaik Jeelani on page 1442. These highly crystalline and irregular platelets influence and increase the surface area of nanoparticles to ∼ 44 m2/g. This significant increase in the materials properties at low loadings of the nanofillers highlights the importance of this new class of bio-based materials, particularly beneficial to the automotive sector where the continued need for material weight reduction must always be balanced with the consideration of structural requirements.
