Book Description
The present volume comprises data on viscosities of non-electrolyte systems, containing pure organic liquids and binary liquid mixtures at normal pressure. Production, transportation and use of liquid materials directly depend on their physical features, among which their viscosities play a key role.Travelling through a pipe, drying out of a building material, dispensing a fluid into packaging are just few examples of how important reliable data on liquid viscosities are.The data present viscosities as a function of temperature and - for binary mixtures - of composition at normal pressure.

Book Description
Taking greater advantage of powerful computing capabilities over the last several years, the development of fundamental information and new models has led to major advances in nearly every aspect of chemical engineering. Albright’s Chemical Engineering Handbook represents a reliable source of updated methods, applications, and fundamental concepts that will continue to play a significant role in driving new research and improving plant design and operations. Well-rounded, concise, and practical by design, this handbook collects valuable insight from an exceptional diversity of leaders in their respective specialties. Each chapter provides a clear review of basic information, case examples, and references to additional, more in-depth information. They explain essential principles, calculations, and issues relating to topics including reaction engineering, process control and design, waste disposal, and electrochemical and biochemical engineering. The final chapters cover aspects of patents and intellectual property, practical communication, and ethical considerations that are most relevant to engineers. From fundamentals to plant operations, Albright’s Chemical Engineering Handbook offers a thorough, yet succinct guide to day-to-day methods and calculations used in chemical engineering applications. This handbook will serve the needs of practicing professionals as well as students preparing to enter the field.

Book Description
Subject of my thesis is a study of rheologic and dynamic properties of fluids confined in an isotropic pore network with pore radii of approx. 5nm embedded in a monolithic silica matrix (porous Vycor). The experimental technique bases on the capillary rise of a wetting liquid in a porous substrate, also known as spontaneous imbibition. A crucial part of the conducted experiments centers on the increasing relevance of the liquid-substrate interface in the mesopore confinement. Detailed analyses of the measurements carried out with water, silicon oils, and a series of hydrocarbons result in precise information on the boundary conditions expressed in terms of the velocity slip length. Systematic variations of the chain-length of the used hydrocarbons also allow for an assessment of the influence of the shape of the liquid's building blocks on the nanoscopic flow behavior. Supplemental forced throughput experiments additionally address the impact of the liquid-substrate interaction. Furthermore, the influences of spatial confinement on the surface freezing transition of the linear hydrocarbon n-tetracosane as well as on the mesophase transitions of the liquid crystal 8OCB are investigated. Finally, a third, more general study focuses on the kinetics of the invasion front, which is supposed to be influenced significantly by the random environment of the pore space considered.

Book Description
The liquid state is possibly the most difficult and intriguing state of matter to model. Organic liquids are required, mainly as working fluids, in almost all industrial activities and in most appliances (e.g. in air conditioning). Transport properties (namely dynamic viscosity and thermal conductivity) are possibly the most important properties for the design of devices and appliances. Most theoretical studies on the liquid state date back to the Fifties however huge advances in experimental studies and applied research on heat and mass transfer in liquids have been achieved during past decades. Most of the models cannot rely on theory alone and are empirical, while for most organic liquids, only a few experimental points and empirical correlations are available in literature.The aim of this book is to present both theoretical approaches and the latest experimental advances on the issue, and to merge them into a wider approach. The book is organised into five chapters. The first chapter presents our theoretical knowledge of the liquid state. The second presents the tentative models for the evaluation of the thermal conductivity of organic liquids and confronts their results with the experimental data available in literature. The third presents the tentative models for the evaluation of the dynamic viscosity of organic liquids and confronts their results with the experimental data available in literature. The fourth presents a deeper review of the choice methods for thermal conductivity and their applications to mixtures of organic liquids and the fifth chapter presents a deeper review of the choice methods for dynamic viscosity and their applications to mixtures of organic liquids.

Book Description
This book is unique in that it brings together published viscosity data, experimental methods, theoretical, correlation and predictive procedures in a single volume. The readers will get a better understanding of why various methods are used for measuring viscosity of different types of liquids and why an experimental method is dependent on fluid characteristics, such as Newtonian or non-Newtonian fluids.

Book Description
With daily signals, Nature is communicating us that its unconscious wicked exploitation is no more sustainable. Our socio-economic system focuses on production increasing without considering the consequences. We are intoxicating ourselves on a daily bases just to allow the system to perpetuate itself. The time to switch into more natural solutions is come and the scientific community is ready to offer more natural product with comparable performance then the market products we are used to deal with. This book collects a broad set of scientific examples in which research groups from all over the world, aim to replace fossil fuel-based solutions with biomass derived materials. In here, some of the most innovative developments in the field of bio-materials are reported considering topics which goes from biomass valorization to the synthesis of high preforming bio-based materials.
