This book focuses on the chemistry of additives for high performance applications and a large number of chemical formulas are displayed in the text. The additives applications include:

• Analysis and separation techniques, such as high performance liquid chromatography, for example ionic liquids.
• Additives for electrical applications, such as capacitors, electrokinetic micropumps, lithium-ion batteries, and other battery types.
• Additives for solar cells for control of the active layer nanomorphology are documented as are additives for electrolyte membranes, fuel cells, such as membrane exchange humidifiers and coolant additives.
• Medical applications include high performance additives for the manufacture of scaffolds, controlled drug release, and nanofibers.
• Additives for lubricants including the deposit control, anti-wear additives, fluid loss control additives in drilling applications.
• Additives for concrete uses such as set retarders, curing accelerators, defoamers, permeability control additives, and corrosion protection additives.
