Thermoplasmonics of Gold-Core Silica-Shell Colloidal Nanoparticles under Pulse Illumination
Core-shell nanoparticles, particularly those having a gold core, have emerged as a highly promising class of materials due to their unique optical and thermal properties, which underpin a wide range of applications in photothermal therapy, imaging, and biosensing. In this study, we present a comprehensive study of the thermal dynamics of gold-core silica-shell nanoparticles immersed in water under pulse illumination. The plasmonic response of the core-shell nanoparticle is described by incorpor…

Particle deposit patterns from evaporation of a sessile colloidal droplet
The present work investigates numerically the transport of colloidal particles within an evaporating sessile droplet and their deposition on the substrate in unfavourable conditions. The coupled phenomena of fluid flow and heat and mass transfer with phase change are modelled by taking into account for the evaporative cooling effect, the surface tension gradient effect at liquid air interface and the particles-substrate interaction effect due to DLVO attractive forces.The results show that in p…

Effect of particle and substrate wettability on evaporation-driven assembly of colloidal monolayers
Assembled monolayers of colloidal particles are crucial for various applications, including opto-electronics, surface engineering, as well as light harvesting, and catalysis. A common approach for self-assembly is the drying of a colloidal suspension film on a solid substrate using technologies such as printing and coating. However, this approach often presents challenges such as low surface coverage, stacking faults, and the formation of multiple layers. We numerically investigate the influenc…

Impact of internal flow and particle-substrate interaction on deposit patterns during evaporation of a colloidal sessile droplet
Our numerical study aims to investigate particle deposit patterns from the evaporation of a sessile colloidal droplet. An in house finite volume code is developed to simulate the coupled phenomena of flow and heat and mass transfer with phase change of the evaporating droplet. The numerical model takes into account evaporative cooling effect, surface tension gradient effect at the liquid-air interface, thermal buoyancy effect inside the droplet, thermosolutal buoyancy effect in the surrounding …

Colloidal nanoparticles in cholesteric liquid crystals: Bulk properties, biaxiality and untwisting
We study the effects of colloidal nanoparticles (NPs) in cholesteric liquid crystal samples in the dilute limit, in a Landau-de Gennes theoretical framework. The effects of the suspended NPs are captured by a homogenized energy, as outlined in [7]. For spatially homogeneous samples, we explicitly compute the critical points and minimizers of the modified Landau-de Gennes energy and show that the presence of NP eliminates the first-order isotropic-nematic phase transition, stabilises elusive bia…

Instabilities in Colloidal Crystals on Fluid Membranes
The complex physics of self-assembly in colloidal crystals on deformable interfaces and surfaces poses interesting possibilities for the designability and synthesis of next-generation metamaterials. The goal of this article is to characterize instabilities arising in colloidal crystals assembled on fluid membranes. The colloidal particles are modeled as pair-wise interacting point particles, constrained to lie on a fluid membrane and yet free to reorganize, and the membrane's elastic energy is …
