Influence of forced convection on sessile droplet evaporation
… systems can leverage the evaporation of sessile droplets to implement this effect for different cooling applications. In the case of human perspiration, droplet evaporation typically occurs under exposure to moving air, or forced convection. However, current approaches to understanding …

A Molecular Dynamics Study of Sessile Droplet Evaporation
… investigate the evaporation process of nanosized droplets adsorbed on a substrate. Beads interacting with each other via Lennard-Jones (LJ) potentials are used to construct the simulation systems. The solid substrate contains 6 layers of beads forming a face-centered-cubic lattice. The bottom 3 …

Sessile Droplet Microfluidic Platforms for Improvements in Mass Spectrometry Sample Preparation
Sessile droplet microfluidic devices (SDMF) allow for small, uniform liquid volumes to be arrayed, addressed, and manipulated independently. SDMF platforms diverge from typical flow-based lab-on-a-chip (LOC) devices while maintaining their advantages (low sample consumption, high throughput, and …

Analysis of heat transfer and fluid flow in an evaporating sessile droplet for evaporative cooling applications
… miniaturized technology. The evaporation of the sessile liquid droplet facilitates the phase change of that liquid and provides cooling to the system, because a large amount of latent heat is required to change the phase. Evaporation takes place at the liquid-vapour interface, so to enhance the …

Analysis and feasibility of an evaporative cooling system with sessile droplet evaporation to provide cooling for microprocessors
… Processor using diffusion based evaporation of sessile droplets. An analytical model is developed to determine the capacity of a single layer of droplets to provide sufficient cooling. It is found that a single layer can provide sufficient cooling for the processors with tiny droplets. A …

Electrohydrodynamic Manipulation of Sessile Droplets by the In-Plane Electric Fields
… (with DC voltages in the kV-range applied) on sessile droplets of multiple pure liquids, solvents, colloidal suspensions (with particles and pigments) and conducting polymers commonly used in painting and coating processes. This fundamental research aims at understanding the principles and …

Photocatalytic thin films: their characterisation and antimicrobial properties
… determined by measuring the contact angle of a sessile droplet of water. Antimicrobial properties of the films were assessed with typical examples of Gram- positive and Gram-negative organisms. Staphylococcus aureus (NCTC 6571) and Escherichia coli (NCTC 10418) were selected. Films demonstrated …

Raman and Surface-Enhanced Raman Spectroscopy Imaging of Droplets: Characterization and Environmental Implications
Droplets are ubiquitous microscopic systems - ranging in size from several nanometers to ~100 micrometers – that undergo abundant environmental interactions. Researchers have shown that droplets can impact both earth climate and air quality through physical and chemical processes. Droplets released …

Droplet behavior on superhydrophobic surfaces: Interfaces, interactions, and transport
… objective of the present work is to study droplet dynamics on smooth hydrophobic and textured superhydrophobic surfaces, and to understand the dependence of interfacial interaction mechanisms on surface morphology. ^ A detailed understanding of the dynamics of droplet response to an applied …

Intricate Dynamics of Droplet-Substrate Interactions Beyond Conventional Limitations
Droplet dynamics, encompassing relatively static processes such as evaporation to more vigorous phenomena like self-propelled jumping, are of considerable interest due to their significance in both natural phenomena and practical applications. These behaviors are pivotal in facilitating mass, …

Experimental Investigation of Synthetic Fines Injection for Enhanced Residual CO2 Trapping during CO2 sequestration
… spectroscopy (XPS) analysis was performed at the sessile droplet location after the experiment, for analysis of surface chemistry. Contact angle measurements on Berea sandstone was performed for any difference between captive bubble and sessile drop method. A high-pressure, high-temperature (HPHT) …

Sessile droplets of salt solutions on inert and metallic surfaces
… we investigate the evaporation behaviour of sessile droplets of aqueous saline solutions on planar inert and metallic surfaces and characterise the corrosion phenomenon for iron surfaces. First we study the evaporation behaviour of sessile salty droplets on inert surfaces for a wide range of …
