Surfactants are molecules that contain groups that are water-loving (hydrophilic) and oil-loving (lipophilic). The central question in formulations is often which of the two portions dominate the behavior of the surfactant. For many years that question was answered in terms of the surfactant structure only. However, the modern view is that the hydrophilic-lipophilic nature of the surfactant is the result of surfactant structure and formulation conditions (nature of the oil, temperature, aqueous phase composition) as captured by a semi-empirical equation called the hydrophilic-lipophilic difference (HLD). The HLD is a dimensionless number that indicate the approach to the point where the surfactant inverts its solubility from being water-soluble (negative HLD) to oil-soluble (positive HLD). The HLD alone is a good indicator of how the formulation could behave but it does not produce any formulation property that can be used to predict product performance. The net-average curvature (NAC) are a set of equations that take the value of HLD to predict the properties of the formulation, such as oil (and/or water) solubilization capacity, interfacial tension, phase diagrams, contact angle and others.Surfactant Formulation Engineering using HLD and NAC will not only introduce the reader to HLD-NAC but also to the practical use of these concepts in numerous applications ranging from application in the petroleum industry, to environmental remediation, to food, cosmetic and pharmaceutical applications, and even nanotechnology. The last part of the book will look at the molecular origins of the empirical terms in HLD via the Integrated Free Energy Model (IFEM).
Green Building: An Engineering Approach to Sustainable Construction fills a void in green building which has good textbook options for practitioners, architects, and sustainability experts, but not an engineering focused textbook focused on green building. This new text takes an engineering approach to evaluating green building techniques, systems, and materials. The book examines the built environment from inside out, looking at minimizing environmental impacts while also considering the economics and energy use and efficiency. While not a test-prep book, it will provide the knowledge foundation that will help prepare the students to take the Leadership in Energy and Environmental Design accreditation exam.As students are often unclear on the evolving employment prospects in this field, particularly for the engineer, the textbook also features six case studies showing different career pathways for engineers in this arena.

Inorganic Chemistry Fourth Edition provides essential information for students of inorganic chemistry and is updated throughout. The presentation of topics is made with an effort to be clear and concise so that the book is portable and user friendly. The text emphasizes fundamental principles—including molecular structure, acid-base chemistry, coordination chemistry, ligand field theory, and solid state chemistry. It is organized into five major themes (structure, condensed phases, solution chemistry, main group and coordination compounds) with several chapters in each. There is a logical progression from atomic structure to molecular structure to properties of substances based on molecular structures, to behavior of solids, etc.The textbook contains a balance of topics in theoretical and descriptive chemistry. For example, the hard-soft interaction principle is used to explain hydrogen bond strengths, strengths of acids and bases, stability of coordination compounds, etc. Discussion of elements begins with survey chapters focused on the main groups, while later chapters cover the elements in greater detail. Each chapter opens with narrative introductions and includes figures, tables, and end-of-chapter problem sets.This new edition features updates throughout, with an emphasis on bioinorganic chemistry and a new chapter on nanostructures and graphene. More in-text worked-out examples encourage active learning and prepare students for their exams.This text is ideal for advanced undergraduate and graduate-level students enrolled in the Inorganic Chemistry course. This core course serves Chemistry and other science majors. The book may also be suitable for biochemistry, medicinal chemistry, and other professionals who wish to learn more about this subject area.
The study of one-shot devices such as automobile airbags, fire extinguishers, or antigen tests, is rapidly becoming an important problem in the area of reliability engineering. These devices, which are destroyed or must be rebuilt after use, are a particular case of extreme censoring, which makes the problem of estimating their reliability and lifetime challenging. However, classical statistical and inferential methods do not consider the issue of robustness.Statistical Modeling and Robust Interference for One-shot Devices offers a comprehensive investigation of robust techniques of one-shot devices under accelerated-life tests. With numerous examples and case studies in which the proposed methods are applied, this book includes detailed R codes in each chapter to help readers implement their own codes and use them in the proposed examples and in their own research on one-shot device-testing data. Researchers, mathematicians, engineers, and students working on accelerated-life testing data analysis and robust methodologies will find this to be a welcome resource.
