Energy Science &Engineering, EarlyView.ABSTRACT The selective hydrogenation of oxygenated compounds is crucial for the conversion of biocrude into platform chemicals. However, the presence of stable oxygenated species, cyclohexanone, in biocrude limits possess a challenge for easy conversion process.

Reversible Nanocomposites With Carbon Nanotubes as the Diene in the Diels–Alder Reaction
Polymer Composites, EarlyView.Scheme of the reversible nanocomposites through DA and rDA reactions with participation of carbon nanotubes. ABSTRACT Carbon nanotubes (CNTs) often require surface functionalization to facilitate uniform distribution and address issues related to aggregation. Due to the sp2 hybridized carbon atoms on their surface, CNTs readily participate in the Diels–
