Abstract

Polymer solar cells can be produced by a continuous low cost coating and drying process. This work details a specialized experimental set-up to enable large scale roll to roll processing. Material properties such as surface energy, surface tension, and viscosity are presented and modelled. The impact of coating method, as well as process parameters (e.g. coating speed, shear rate, solvent composition) on process stability and film properties, is discussed.

Abstract

Slime, goo, gunge, gloop, gels, sols, globules, jellies, emulsions, greases, soaps, syrups, glues, lubricants, liquid crystals, moulds, plasmas, and protoplasms – the viscous is not one thing, but rather a quality of resistance and flow, of stickiness and slipperiness. It is a state of matter that oozes into the gaps of our everyday existence, across age groups, between cultures and disciplines.Since the large-scale extraction of petroleum in the 19th century the viscous has witnessed a proliferation in the variety of its forms. Mechanized industry required lubricants and oil distillation produced waste products that were refined to form Vaseline. From this age, new viscous forms and technologies emerged, products from plastic (and plastic explosives) to cosmetics, glycerine, asphalt, sexual lubrication, hydro- and aero- gels, even anti-climb paint.Based on unique and wide-ranging research, The Viscous is the first major investigation of viscous encounter and possibility over the course of the last century, not simply as a material state, but also an imaginative event. We enter into a story of matter at its most wayward, deviant, hesitant, and resistant.From asphalt lakes to industrial molasses tanks, from liquid crystals squirming in our screens to milk fetishes, The Viscous discloses gooeyness as a peculiarly modern phase of matter. "Everything oozes," as Beckett’s Estragon famously proclaims in Waiting for Godot. Viscous dynamics are exposed as not only hugely various in a post industrial age, but particularly useful ways of thinking, feeling, writing, and making in a time of ecological anxiety.

Abstract

Non-Newtonian (non-linear) fluids are common in nature, for example, in mud and honey, but also in many chemical, biological, food, pharmaceutical, and personal care processing industries. This Special Issue of Fluids is dedicated to the recent advances in the mathematical and physical modeling of non-linear fluids with industrial applications, especially those concerned with CFD studies. These fluids include traditional non-Newtonian fluid models, electro- or magneto-rheological fluids, granular materials, slurries, drilling fluids, polymers, blood and other biofluids, mixtures of fluids and particles, etc.

Abstract

Understanding of the role of turbulence in controlling transport processes is of paramount importance for the preservation and protection of aquatic ecosystems, the minimization of the deleterious consequences of anthropogenic activity, and the successful sustainable development of river and maritime areas. In this context, the present Special Issue collects 15 papers which provide a representation of the present understanding of turbulent processes and their effects in river and maritime environments. The presented collection of papers is not exhaustive, but it highlights the key priority areas and knowledge gaps in this field of research. The published papers present the state-of-the-art knowledge of complex environmental flows which are useful for researchers and practitioners. The paper contents are an overview of some recent topics of research and an exposure of the current and future challenges associated with these topics.

Abstract

Natural products and the preparations based on them play a stable and ever-increasing role in human and veterinary medicine, agriculture, in food and the cosmetic industry, and in an increasing number of other fields. Their importance is based on the fact that they are mostly bound to renewable sources, which in fact makes them valuable within a circular economy, inter alia. At the same time, natural products provide the origin of stereochemistry, optical activity, regioselectivity, chirality, and many other concepts and directions within science, development, and industry in a scope, which is indispensable. They serve as a constant powerful stimulus and model that inspires researchers to create new effective tools, similar to natural ones, for controlling bioregulation mechanisms and solving practical problems. This was the reason for organizing this Special Issue aimed at underlining the current developments in all the fields connected to natural products.

Abstract

Turbulent transport is currently a prominent and ongoing investigation subject at the interface of methodologies from theory to numerical simulations and experiments, and it covers several spatiotemporal scales. Mathematical analysis, physical modelling, and engineering applications represent different facets of a classical, long-standing problem that is still far from being thoroughly comprehended. The goal of this Special Issue is to outline recent advances of such subjects as multiscale analysis in turbulent transport processes, Lagrangian and Eulerian descriptions of turbulence, advection of particles and fields in turbulent flows, ideal or nonideal turbulence (unstationary/inhomogeneous/anisotropic/compressible), turbulent flows in biofluid mechanics and magnetohydrodynamics, and the control and optimization of turbulent transport. The SI is open to regular articles, review papers focused on the state of the art and the progress made over the last few years, and new research trends.

Abstract

Energy has been a crucial element for human beings and sustainable development. The issues of global warming and non-green energy have yet to be resolved. This book is a collection of twelve articles that provide strong evidence for the success of artificial intelligence deployment in energy research, particularly research devoted to non-intrusive load monitoring, network, and grid, as well as other emerging topics. The presented artificial intelligence algorithms may provide insight into how to apply similar approaches, subject to fine-tuning and customization, to other unexplored energy research. The ultimate goal is to fully apply artificial intelligence to the energy sector. This book may serve as a guide for professionals, researchers, and data scientists—namely, how to share opinions and exchange ideas so as to facilitate a better fusion of energy, academic, and industry research, and improve in the quality of people's daily life activities.

Abstract

Geothermal energy is the thermal energy generated and stored in the Earth's core, mantle, and crust. Geothermal technologies are used to generate electricity and to heat and cool buildings. To develop accurate models for heat and mass transfer applications involving fluid flow in geothermal applications or reservoir engineering and petroleum industries, a basic knowledge of the rheological and transport properties of the materials involved (drilling fluid, rock properties, etc.)—especially in high-temperature and high-pressure environments—are needed. This Special Issue considers all aspects of fluid flow and heat transfer in geothermal applications, including the ground heat exchanger, conduction and convection in porous media. The emphasis here is on mathematical and computational aspects of fluid flow in conventional and unconventional reservoirs, geothermal engineering, fluid flow, and heat transfer in drilling engineering and enhanced oil recovery (hydraulic fracturing, CO2 injection, etc.) applications.

Abstract

This collection of research and review papers is aimed at depicting the state of the art on the possible correlations between processing variables, obtained structure and special properties which this structure induces on the plastic part. The extraordinary capacity of plastics to modify their properties according to a particular structure is evidenced for several transformation processes and for many applications. The final common goal is to take profit of this peculiar capacity of plastics by inducing, through a suitable processing, a specific spatial organization.
