Journal Article
OKPOZO, P., NJUGUNA, J., ISLAM, S., UYANGA, K. and PANCHOLI, K. 2024. Fabrication with magnetic-spin coating: influence of magnetic-inertia energy ratio on gold-pickering ferrofluid droplet assembly morphology. Journal of magnetism and magnetic materials [online], 611, article number 172577. Available from: https://doi.org/10.1016/j.jmmm.2024.172577

Magnetic self-assembly of nanoparticles is a well-known technique for creating thin-film array-patterned functional microstructures. However, an uncontrollable hierarchical assembly formation of magnetically stimulated particles has hindered the desi...

Enhancement of infrared absorption through a patterned thin film of magnetic field and spin-coating directed self-assembly of gold nanoparticle stabilised ferrofluid emulsion. (2023)
Journal Article
OKPOZO, P., DWIVEDI, Y., HUO, D. and PANCHOLI, K. 2023. Enhancement of infrared absorption through a patterned thin film of magnetic field and spin-coating directed self-assembly of gold nanoparticle stabilised ferrofluid emulsion. RSC advances [online], 13(34), pages 23955-23966. Available from: https://doi.org/10.1039/d3ra01369c

Molecular vibration signals were amplified by the gold strip gratings as a result of grating resonances and nearby electric field hotspots. Colloidal gold island films exhibit similar enhancement; however, the uneven geometrical characteristics of th...

Study of spatial organisation of magnetic field directed gold-pickering-ferrofluid-nanoemulsion in spin coated film. (2023)
Journal Article
OKPOZO, P. and PANCHOLI, K. 2023. Study of spatial organisation of magnetic field directed gold-pickering-ferrofluid-nanoemulsion in spin coated film. Hybrid advances [online], 2, article 100018. Available from: https://doi.org/10.1016/j.hybadv.2023.100018

The magnetic field directed self-assembly of the nanoparticles is cheap, fast and easy method to prepare the patterned thin film useful for various applications. However, the dipole-dipole interaction between nanoparticles at the interface generates...
