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
Nanodroplets, the basis of complex and advanced nanostructures such as quantum rings, quantum dots and quantum dot clusters for future electronic and optoelectronic materials and devices, have attracted the interdisciplinary interest of chemists, physicists and engineers. This book combines experimental and theoretical analyses of nanosized droplets which reveal many attractive properties. Coverage includes nanodroplet synthesis, structure, unique behaviors and their nanofabrication, including chapters on focused ion beam, atomic force microscopy, molecular beam epitaxy and the "vapor-liquid- solid" route. Particular emphasis is given to the behavior of metallic nanodroplets, water nanodroplets and nanodroplets in polymer and metamaterial nanocomposites. The contributions of leading scientists and their research groups will provide readers with deeper insight into the chemical and physical mechanisms, properties, and potential applications of various nanodroplets.

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
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
Evaporation and Droplet Growth in Gaseous Media deals with the evaporation of droplets of liquid in gaseous media and the reverse process of droplet growth in a medium supersaturated with the vapor of the liquid. Thediscussion is restricted to the kinetics of evaporation and growth of droplets of pure liquids (and heat transfer to the same). Comprised of three chapters, this book first examines the quasi-stationary evaporation and growth of droplets that are motionless relative to the medium and the hydrodynamic factor is absent. The Maxwell equation, the basis of the theory of evaporation of droplets in a gaseous medium, is taken into account. The influence of the Stefan flow and the concentration change at the surface on the rate of evaporation are considered, along with the evaporation of droplets in a vessel with absorbing walls and the fall in temperature of both free evaporating droplets and supported evaporating droplets. The second chapter is devoted to the quasi-stationary evaporation of droplets in a stream of gas, that is, droplets moving relative to the medium. The last chapter focuses on non-stationary evaporation and growth of droplets that either motionless or moving relative to the medium. This monograph will be of interest to students, practitioners, and researchers in inorganic and structural chemistry.
