Synthesis and characterisation of hollow monodisperse silica-titania nanostructures for potential use in targeted delivery of drugs/vaccines/genes
… nanocarriers which avoid the above limitations. Hollow nanoparticles with their hollow cavity and favourable surface modification, offer a great deal of promise in drug delivery applications. However, a good understanding and thorough characterisation of these nanoparticulate systems is crucial. …

Surface Oxidation and Dissolution of Metal Nanocatalysts in Acid Medium
… The results on the degradation of Pt nanoparticles under different potential regimes demonstrate that the dissolution depends on the potential path to which the nanocatalyst is exposed. Metal atoms detach from the boundaries of (111) facets expecting a reduction in the activity of the …

Coupled mechanochemical theories for reacting systems with application to nanovoid nucleation and Li-ion batteries
<p>Hollow nanoparticles (NPs) are produced by void nucleation and growth during chemical reactions. However, there is no proper understanding of nucleation and growth mechanisms, and their predictive modeling. Furthermore, models based on the Kirkendall effect predict the process time, which is …

Investigation of metal nanomaterials as a sensing element in LSPR-based optical fibre sensor development
… level when light interacts with metallic nanoparticles at a resonance wavelength. The LSPR effect of metallic nanomaterials has shown a strong dependence on the local surrounding environment. A small change for example in the refractive index or in the solution concentration can result in …

DESIGN AND SYNTHESIS OF STAINLESS-STEEL NANOPARTICLES: OXIDATION BEHAVIOR AND MORPHOLOGICAL EVOLUTION
… synthesis of oxidation resistant stainless-steel nanoparticles. To this effect, I employed bottom-up wet chemistry approach to synthesize multi-shell Fe/CrxNi1-x NPs, bimetallic FexCr1-x alloy NPs, and Fe/Ni core/shell NPs. I performed the morphological analysis of these NPs via transmission …
