Encapsulation is a topic of interest across a wide range of scientific and industrial areas, from pharmaceutics to food and agriculture, for the protection and controlled release of various substances during transportation, storage, and consumption. Since encapsulated materials can be protected from external conditions, encapsulation enhances their stability and maintains their viability. This book offers a comprehensive review of conventional and modern methods for encapsulation. It covers various thermal and nonthermal encapsulation methods applied across a number of industries, including freeze drying, spray drying, spray chilling and spray cooling, electrospinning/electrospraying, osmotic dehydration, extrusion, air-suspension coating, pan coating, and vacuum drying. The book presents basic fundamentals, principles, and applications of each method, enabling the reader to gain extended knowledge. The choice of the most suitable encapsulation technique is based on the raw materials, the required size, and the desirable characteristics of the final products.

Biocatalysis in the Pharmaceutical and Biotechnology Industries showcases the practical advantages and methodologies for using biocatalysts to develop and produce chiral pharmaceuticals and fine chemicals.

Chemical formulation can be traced back to Stone Age times, when hunter-gatherers attached flint arrowheads to shafts using a resin made from birch bark and beeswax. Today, formulated preparations are part of everyday life. Formulations based on surfactants are by far the most prolific, from shampoos and shower gels to emulsion paint and polishes. This book discusses the chemical technology of surfactants and related chemicals, using over forty examples of everyday products. Some basic theory on surface chemistry, molecular interactions and surfactant function is included to aid understanding. Chemical Formulation: An Overview of Surfactant-based Preparations Used in Everyday Life then goes on to look at wider aspects such as surfactant manufacture, raw materials, environment, sustainability, analysis and testing. Throughout, common chemical names are used for formulation chemicals, further aiding the readability of the book. Bridging the gap between theory and application, this book will be invaluable to anyone wishing to broaden their knowledge of applied chemistry, including students on A level, BTEC and technician courses.

Traditionally, design and control decisions are made in sequential stages over the life cycle of a chemical plant. In the design phase, the optimal operating conditions and the corresponding material and energy balance data are established mainly on the basis of economic considerations. In the subsequent step, the control systems are configured to maintain the key process conditions at the fixed nominal values. Because it is often desirable to address the operability issues at the earliest possible stage before stipulation of control schemes, the systematic incorporation of flexibility analysis in process synthesis and design has received considerable attention in recent years. This book focuses to a large extent on computation and implementation methods of deterministic performance measures, i.e., the steady-state, volumetric, dynamic and temporal flexibility indices, in various applications. The formal definitions of several available performance indices, their mathematical formulations, and the corresponding algorithms and codes are provided in sufficient detail to facilitate implementation. To show the utility of flexibility analyses, the book presents several practical case studies including membrane modules and heat-exchanger networks, solar-driven membrane distillation desalination systems, and hybrid power generation systems. It also includes MATLAB and GAMS codes.
