Preface

Dynamical changes and modulations in surface wetting and surface tension-related processes across solid/liquid interfaces can have a significant impact on overall reaction kinetics and have been the focus of extensive research in physical, chemical, biological, agricultural, and environmental sciences. Some of the key applications include studies on groundwater flows, oil spills, water management, disease transmission, chemical leaching, nanotechnology, etc. This book presents a wide spectrum of studies in the fields of nanomaterials, oil recovery in the petroleum industry, metal processing, surface tension and viscosity of fluids, and superhydro-

The book has an introductory chapter and seven full chapters with contributing authors from Australia, the People's Republic of China, Japan, Brazil, Egypt, Canada, Hong Kong, and Romania. Global authorship in this book reflects multifaceted interest and activity in this field worldwide with breakthroughs occurring

The table of contents is organized considering novel applications of wettability and interfacial phenomena to different fields, including practical treatments to enhance system behaviour. These include nanoscale wettability, interactions of oil with metals and reservoir rocks for applications in the petroleum industry, the role of coatings, particle morphology, surface roughness and viscosity in metal processing,

The introductory chapter presents an overview of factors influencing the wettability of nanomaterials, a key and emerging area of wettability research. Nanoscale surface interactions between graphene, carbon nanotubes, and other materials with water, aqueous solutions, and polymers can play a significant role in water filtration, desalination, and polymer dispersion applications. Key factors that could be used to modify and control nanoscale wetting behaviour are discussed along with novel wetting investigations on nanochannels, membranes, and

The second chapter reports on the wetting behaviour of oil-impregnated sintered bearings and friction reduction for applications in automobile parts, office automation equipment, motor vehicles, etc. Shaft surface oil wettability was investigated for PTFE-coated shaft-impregnated sintered bearings and compared to noncoated shafts as an effective means of reducing friction. With oil from the porous bearing body lubricating the shaft and bearing surfaces, the low oil-wettable shaft was found to retain a larger amount of oil in the bearing clearances and indicated lower

The third chapter reports on determining a complete wettability profile based on zeta potential measurements on reservoir rocks, one of the primary factors that control location, saturation, distribution, and flow behaviour of reservoir fluids.
