'Nano on micro' hierarchical porous all carbon structures: an insight into interfacial interactions with bacteria.

Micron long carbon nanofibers (CNFs) were grown on porous carbon beads to give an active surface for rapid immobilization of guest molecules. The fabrication of nanostructures using a catalytic route involving chemical vapour deposition on a porous substrate was accomplished by the controlled synthesis of iron nanoclusters on the surface of porous carbon beads. The challenge of catalyst nanoparticle diffusion into the porous substrate was addressed by using iron coordinated ligand complexes and optimizing the loading percentage of metal salts onto beads.

Effect of Reinforcement at Length Scale for Polyurethane Cellular Scaffolds by Supramolecular Assemblies.

This study is aimed to represent the role of carbonaceous nanofillers to reinforce the commercially available polyurethane porous structure. The effect of dimensionality of fillers to anchor the construction of stable three-dimensional (3D) cellular architectures has been highlighted. The cellular frameworks of commercially available thermoplastic polyurethane (TPU) have been fabricated through the thermoreversible supramolecular self-assembly route.

Evidence of C--F-P and aromatic π--F-P weak interactions in imidazolium ionic liquids and its consequences.

A simple change from alkyl group to alkene in side chain of imidazolium cation with same anion resulted in a drastic impact on physical properties (e.g., melting point) from bmimPF IL to cmimPF IL.

Derivatization and interlaminar debonding of graphite-iron nanoparticle hybrid interfaces using Fenton chemistry.

The interfacial debonding of graphite lattices using iron (Fe) nanoparticles and Fenton's reagent is reported, towards the scalable production of few-layer graphene flakes. Acoustic cavitation via a sonochemical route was adapted to produce iron and iron oxide nanoparticles in the graphite matrix. The oxygenated species were introduced into the graphite lattice using a physical method, and then Fenton chemistry was utilized to generate localized hydroxyl radicals at the Fe nanoparticle-graphite interfaces for zipping and self-exfoliation of the defected graphite lattices.
