Book Description
The high, fast and local heat transfer associated with the deposition and evaporation of a single droplet on a flat surface has potential applications in spray evaporative cooling. Controlled evaporation of microdroplets containing colloidal particles can be used to manufacture nanowires, explosive crystalline layers and DNA spots for gene expression analysis. The physics of this phenomenon is a complex interplay of fluid dynamics in presence of a severely deforming free surface, wetting line motion, convective and conductive heat transfer, mass transfer due to evaporation and advection-diffusion of particles inside the droplet. In this book, Rajneesh Bhardwaj proposes a numerical modeling to investigate the interplay of transport phenomena during droplet impact and evaporation, for the case of a pure liquid or a colloidal solution. Comparions of numerical results with available or in-house experiments are made wherever possible.

Book Description
Self-Cleaning of Surfaces and Water Droplet Mobility deals with the self-cleaning of hydrophobic surfaces. Chapters cover the basics of wetting states of fluids and surface characteristics in terms of texture topology and free energy. The self-cleaning aspects of surfaces, such as various synthesizing and fabrication processes are then introduced and discussed, along with environmental dust properties, including elemental compositions, particle sizes and shapes, and their chemo-mechanics characteristics. In addition, mud formation in humid air, as well as ambient and dry mud adhesion on optically transparent surfaces is explored, as is water droplet dynamics on hydrophilic and hydrophobic surfaces, amongst other topics. The book fills the gap between the physical fundamentals of surface energy and texture characteristics for practical applications of surface cleaning and provides a basic understanding of the self-cleaning of surfaces that will be idea for academics, researchers and students. - Showcases the fundamental aspects of the self-cleaning of surfaces - Includes practical applications in energy and other sectors - Contains a review of the characterization of environmental dust on hydrophilic and hydrophobic surfaces - Discusses the fabrication and optimization of surfaces towards self-cleaning - Presents practical applications of the self-cleaning of surfaces via water droplet mobility

Book Description
The use of spontaneous self-assembly, as a lithographic tool and as an external field-free means to construct well-ordered and intriguing patterns, has received much attention due to its ease of producing complex, large-scale structures with small feature sizes. An extremely simple route to highly-ordered, complex structures is the evaporative self-assembly of nonvolatile solutes (e.g., polymers, nanoparticles, carbon nanotubes, and DNA) from a sessile droplet on a solid substrate. To date, a few studies have elegantly demonstrated that self-organized nanoscale, microscale, and hierarchically structured patterns have been readily obtained from sophisticated control of droplet evaporation. These include convective assembly in evaporating menisci, the alignment of nanomaterials by programmed dip coating and controlled anisotrophic wetting/dewetting processes, facile microstructuring of functional polymers by the “Breath Figure” method, controlled evaporative self-assembly in confined geometries, etc.This book is unique in this regard in providing a wide spectrum of recent experimental and theoretical advances in evaporative self-assembly techniques. The ability to engineer an evaporative self-assembly process that yields a broad range of complex, well-ordered and intriguing structures with small feature sizes composed of polymers of nanocrystals of different size and shapes as well as DNA over large areas offers tremendous potential for applications in electronics, optoelectronics, photonics, sensors, information processing and data storage devices, nanotechnology, high-throughput drug discovery, chemical detection, combinatorical chemistry, and biotechnology.

Book Description
Building on advances in miniaturization and soft matter, surface tension effects are a major key to the development of soft/fluidic microrobotics. Benefiting from scaling laws, surface tension and capillary effects can enable sensing, actuation, adhesion, confinement, compliance, and other structural and functional properties necessary in micro- and nanosystems. Various applications are under development: microfluidic and lab-on-chip devices, soft gripping and manipulation of particles, colloidal and interfacial assemblies, fluidic/droplet mechatronics. The capillary action is ubiquitous in drops, bubbles and menisci, opening a broad spectrum of technological solutions and scientific investigations. Identified grand challenges to the establishment of fluidic microrobotics include mastering the dynamics of capillary effects, controlling the hysteresis arising from wetting and evaporation, improving the dispensing and handling of tiny droplets, and developing a mechatronic approach for the control and programming of surface tension effects. In this Special Issue of Micromachines, we invite contributions covering all aspects of microscale engineering relying on surface tension. Particularly, we welcome contributions on fundamentals or applications related to: Drop-botics: fluidic or surface tension-based micro/nanorobotics: capillary manipulation, gripping, and actuation, sensing, folding, propulsion and bio-inspired solutions; Control of surface tension effects: surface tension gradients, active surfactants, thermocapillarity, electrowetting, elastocapillarity; Handling of droplets, bubbles and liquid bridges: dispensing, confinement, displacement, stretching, rupture, evaporation; Capillary forces: modelling, measurement, simulation; Interfacial engineering: smart liquids, surface treatments; Interfacial fluidic and capillary assembly of colloids and devices; Biological applications of surface tension, including lab-on-chip and organ-on-chip systems.
