Book Synopsis Fundamentals of Phase Separation in Polymer Blend Thin Films by : Sam Coveney
Download or read book Fundamentals of Phase Separation in Polymer Blend Thin Films written by Sam Coveney and published by Springer. This book was released on 2015-06-18 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work sheds new light on fundamental aspects of phase separation in polymer-blend thin films. A key feature underlying the theoretical models is the unification of one-dimensional thermodynamic phase equilibria with film evolution phenomena in two- and three dimensions. Initially, an established 'phase portrait' method, useful for visualising and calculating phase equilibria of polymer-blend films, is generalised to systems without convenient simplifying symmetries. Thermodynamic equilibria alone are then used to explain a film roughening mechanism in which laterally coexisting phases can have different depths in order to minimise free energy. The phase portraits are then utilised to demonstrate that simulations of lateral phase separation via a transient wetting layer, which conform very well with experiments, can be satisfactorily explained by 1D phase equilibria and a 'surface bifurcation' mechanism. Lastly, a novel 3D model of coupled phase separation and dewetting is developed, which demonstrates that surface roughening shadows phase separation in thin films.
Book Synopsis Nanoscale Phase Separation and Colossal Magnetoresistance by : Elbio Dagotto
Download or read book Nanoscale Phase Separation and Colossal Magnetoresistance written by Elbio Dagotto and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the spontaneous formation of nanostructures in single crystals of several compounds is now a major area of research in strongly correlated electrons. These structures appear to originate in the competition of phases. The book addresses nanoscale phase separation, focusing on the manganese oxides known as manganites that have the colossal magnetoresistance (CMR) effect of potential relevance for device applications. It is argued that the nanostructures are at the heart of the CMR phenomenon. The book contains updated information on manganite research directed to experts, both theorists and experimentalists. However, graduate students or postdocs will find considerable introductory material, including elements of computational physics.
Book Synopsis Phase Separation in Cuprate Superconductors by : Ernst Sigmund
Download or read book Phase Separation in Cuprate Superconductors written by Ernst Sigmund and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase separation has become a fascinating subject in the discussion of cuprate superconductors. All these materials have layered structures containing CU02 planes as the most important building blocks. They are coupled only weakly so that the electronic properties show a nearly two-dimensional behaviour. Due to correlations the undoped compounds are insulators of the Mott Hubbard type exhibiting long-range antiferromagnetic order. Upon doping a rich scenario of physical phenomena appears: Even at low hole concentra tions the antiferromagnetic ordering temperature is reduced drastically and spin-glass behaviour as well as a hopping type conductivity can be observed. Further doping leads to metallic-like conductivity and below Tc to super conductivity. In this doping regime antiferromagnetic fluctuations are still observed. At very high charge carrier densities superconductivity is lost and the systems show pure metallic conduction without ,magnetic correlations. One of the most interesting phenomena in high-T c research is the interplay between magnetism and conductivity or superconductivity. Especially the behaviour of charge carriers in the antiferromagnetic background raises a number of open questions. Two scenarios become possible: the carriers tend to delocalize over the whole crystal forming a homogeneous state with band-like structure or they separate into hole-rich (conducting, superconducting) and hole-poor (insulating, antiferromagnetic) phases leading to an inhomogeneous structure.

Book Synopsis Phase Separation in Two-phase Microfluidic Heat Exchangers by : Milnes P. David
Download or read book Phase Separation in Two-phase Microfluidic Heat Exchangers written by Milnes P. David and published by Stanford University. This book was released on 2011 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-phase microfluidic heat exchangers have the potential to meet the large heat dissipation demands of high power electronics and computing systems. Two-phase cooling systems face practical challenges brought on by the growth and advection of the vapor phase in the confined geometries, which lead to large pressure drops, increased thermal resistance and the formation of detrimental flow instabilities. One proposed solution to these issues is phase separation, whereby the vapor is locally separated from the two-phase flow through a porous hydrophobic membrane. This dissertation describes a series of studies conducted to develop an understanding of the factors that influence vapor separation and its impact on the hydraulic and thermal characteristics of two-phase heat exchangers. Flow phenomena are a critical component in developing this understanding of phase separation. High speed visualization of adiabatic and diabatic vaporizing flows was carried out in a single 124[Mu]m by 98[Mu]m copper microchannel with a 65[Mu]m thick, 220nm pore diameter hydrophobic PTFE membrane wall. During adiabatic air-water flow, wavy-stratified and stratified flow dominated lower liquid velocities, while plug and annular type flows dominated at the higher velocities. Analysis found that air removal could be improved by increasing the venting area, increasing the trans-membrane pressure or using thinner, high permeability membranes. Diabatic water-vapor experiments with mass flux velocities of 140 and 340 kg/s-m2 and exit qualities up to 20% found that stratified type flows dominate at lower mass fluxes while cyclical churn-annular flow became more prevalent at the higher mass-flux and quality. The observed flow regimes are hypothesized to play a significant role in determining the pressure drop and heat transfer coefficient during flow boiling. To study the impact of various geometric and membrane factors on the performance of a phase separating microchannel heat exchanger dissipating 100W of heat, a numerical model incorporating vapor separation and transport during two-phase flow boiling in a microchannel was developed. The impact of substrate thermal conductivity and thickness, membrane permeability and thickness, liquid channel density, liquid and vent channel diameter and vent-to-liquid channel diameter ratio was studied and compared for a standard non-venting heat exchanger, a vapor venting heat exchanger and a non-venting heat exchanger occupying the same increased volume as the venting heat exchanger. The numerical study found that the venting heat exchanger had improved pressure drop and device temperatures for all tested conditions when compared against a standard heat exchanger but only under very limited conditions when compared against the volumetrically equivalent non-venting heat exchanger. The study indicates that the best venting heat exchanger performance is achieved when the membrane conductance is of the same order or higher than that of the microchannel; this can be achieved through the use of thin high permeability membranes coupled with small hydraulic diameter microchannels. Finally, a study was conducted to explore the fabrication methods to build a vapor separating heat exchanger and to quantify the operating performance of multichannel silicon and copper phase separating devices. A copper parallel microchannel heat exchanger with nineteen 130[Mu]m square microchannels was built and tested at heat fluxes of up to 820 kW/m2 and water mass fluxes of between 102 and 420 kg/s-m2. Normalized pressure drop was improved by as much as 60% and average substrate temperature by a maximum of 4.4°C between the non-venting control and vapor venting device under similar operating conditions. Comparison between the experimental results and simulation predictions found higher than expected pressure drop improvements at higher mass fluxes and poorer heat transfer coefficients at the lowest mass flux. Based on the flow phenomena study these discrepancies are believed to be due to the mass flux and vapor quality dependent two-phase flow structures. The encouraging experimental and numerical results motivate further study into phase separation methods, materials and flow physics. The development of a high performance phase separating heat exchanger, with the thermal benefits of two-phase boiling flow and the hydraulic benefits of single-phase liquid flow, would strongly enable the adoption and application of two-phase heat exchangers to provide effective and efficient cooling for next generation high power computing systems.
Book Synopsis Phase Separation In Cuprate Superconductors - Proceedings Of The Workshop by : Karl Alex Muller
Download or read book Phase Separation In Cuprate Superconductors - Proceedings Of The Workshop written by Karl Alex Muller and published by World Scientific. This book was released on 1993-01-08 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this workshop was to review and discuss the electronic and chemical properties of layered cuprate superconductors. These are doped antiferromagnetic (AFM) insulators, and there is the possibility of a dynamic phase separation into metallic clusters and AFM areas. A clarification on the existence and the mechanism of such a phase separation is believed to be crucial for the understanding of high-Tc superconductivity in cuprates.On the one hand, theoretical and recent experimental indications in favor of this possibility were presented, on the other hand experimental papers expressing more skeptical views were also delivered. Related work on phase separations of chemical and structural origin was also included, followed by contributions on the question; “If phase separation is present, what is the pairing mechanism in the metallic clusters?”.

Book Synopsis Phase Separation in Living Cells by : Riki Kurokawa
Download or read book Phase Separation in Living Cells written by Riki Kurokawa and published by Springer Nature. This book was released on 2023-10-31 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest cutting-edge research on phase separation. It discusses the benefits and risks of phase separation for living cells from the perspectives of physics, chemistry, biology, and medicine. Phase separation is a physico-chemical process that induces a single solution of solvent and intrinsically disordered proteins (IDPs) to separate into two phases, one phase containing only solvent and the other containing IDPs in the solvent. A key molecule in phase separation is the intrinsically disordered region (IDR) proteins (IDPs), mostly comprised of RNA-binding proteins (RBPs). One of the major roles of phase separation is to generate condensates, membrane-less organelles including stress granule, Cajal body, and nucleolus. Biological actions of phase separation in various aspects of science have received increasing attention in recent years. The book consists of four parts; Part I on physics and chemistry includes topics on structural biology of RBP FUS/TLS and chaperone for phase separation, computational approach of phase separation, and chemistry of G-quadruplex of DNA and RNA. Part II on molecular biology presents molecular mechanism of IDR sequence phase separation and potential cellular function of these labile fibers, formation of membrane-less organelles, and roles of noncoding RNAs in phase separation. Part III on biology covers topics from nuclear pore complex, developmental biology regarding force-dependent remodeling, and neurobiology and higher order brain functions. Finally, Part IV on medicine presents condensates and cancer therapy, pathogenesis of neurodegenerative diseases based on IDPs, and responses of microglia to amyloid. The last chapter highlights the latest topic on how the SARS-Cov-2 virus takes advantage of phase separation for its infections. This book brings together the studies of phase separation in each area in a single volume. The comprehensive approach provides new insights to the research and will benefit the readers by responding to the emerging needs for understanding phase separation.
