Book Description
This book is an expanded form of the monograph, Dropwise Condensation on Inclined Textured Surfaces, Springer, 2013, published earlier by the authors, wherein a mathematical model for dropwise condensation of pure vapor over inclined textured surfaces was presented, followed by simulations and comparison with experiments. The model factored in several details of the overall quasi-cyclic process but approximated those at the scale of individual drops. In the last five years, drop level dynamics over hydrophobic surfaces have been extensively studied. These results can now be incorporated in the dropwise condensation model. Dropwise condensation is an efficient route to heat transfer and is often encountered in major power generation applications. Drops are also formed during condensation in distillation devices that work with diverse fluids ranging from water to liquid metals. Design of such equipment requires careful understanding of the condensation cycle, starting from the birth of nuclei, followed by molecular clusters, direct growth of droplets, their coalescence, all the way to instability and fall-off of condensed drops. The model described here considers these individual steps of the condensation cycle. Additional discussions include drop shape determination under static conditions, a fundamental study of drop spreading in sessile and pendant configurations, and the details of the drop coalescence phenomena. These are subsequently incorporated in the condensation model and their consequences are examined. As the mathematical model is spread over multiple scales of length and time, a parallelization approach to simulation is presented. Special topics include three-phase contact line modeling, surface preparation techniques, fundamentals of evaporation and evaporation rates of a single liquid drop, and measurement of heat transfer coefficient during large-scale condensation of water vapor. We hope that this significantly expanded text meets the expectations of design engineers, analysts, and researchers working in areas related to phase-change phenomena and heat transfer.

Book Description
Dropwise Condensation on Textured Surfaces presents a holistic framework for understanding dropwise condensation through mathematical modeling and meaningful experiments. The book presents a review of the subject required to build up models as well as to design experiments. Emphasis is placed on the effect of physical and chemical texturing and their effect on the bulk transport phenomena. Application of the model to metal vapor condensation is of special interest. The unique behavior of liquid metals, with their low Prandtl number and high surface tension, is also discussed. The model predicts instantaneous drop size distribution for a given level of substrate subcooling and derives local as well as spatio-temporally averaged heat transfer rates and wall shear stress.

Book Description
Extracellular Matrix (ECM) has been considered for a long time merely a scaffold sustaining cell and tissue function. Despite this simplistic view shared by many, nowadays ECM and their mechanic-physical and chemical characteristic acquired a progressive larger role actively regulating cell life: survival, proliferation, gene expression and differentiation. The interplay between cells and the ECM is continuously controlled at the cell level in a dynamic way. While cells synthesize the raw components of the ECM, this in turn impacts on cell function by providing chemical, topographical and mechanical hints. Such stimuli have been proven to control several aspects of cell function, including survival, proliferation, differentiation and migration. The molecular pathways activated by cells in response to the physical cues arising from the ECM are being disclosed and thus the possibility to control cell function through materials design is becoming more realistic. Current in vitro protocols, relying in 2D cell culture system, entail reductionist approaches to the complexity of cell-ECM interaction and result in cells rapidly losing their distinctive functions in culture. Understanding and replicating the 3D microenvironmental cues affecting cell function appears as a mandatory requirement for the development of next-generation biomaterials, as well as for the establishment of more physiologically relevant and predictive in vitro models of diseases. Such an effort will require a multidisciplinary approach at the convergence of biophysics, biology, nanotechnology, and bioengineering.
