Book Description
It has been shown that the degree of adhesion of metals depends upon the surface cleanliness. This paper presents a method that was used to characterize the surface cleanliness of nickel during an adhesion experiment. The change in the work function of the surface as the metal was cleaned was used to indicate the degree of cleanliness. The point at which the work function was stable with additional cleaning was used as the cleanest surface. The cleaning technique was an argon-ion bombardment and heating process. Measurements of the adhesion force showed that the maximum adhesion forces occurred when the surfaces were the cleanest. The cleaned surfaces were recontaminated with oxygen and the adhesion force decreased to zero.

Book Description
Coatings offer the unique opportunity to create architectures that combine the functionality of two or more materials, conferring unique properties to objects with an extremely large palette of solutions. For this flexibility, thick and thin films have terrific impacts on the most relevant societal challenges. Computers, food packaging, airplanes, and cars, to mention a few familiar objects from everyday life, rely heavily on coatings. To celebrate the key role that coatings have in society, and in science and technology, this book collects a selection of relevant reviews and original research articles published in “Coatings” in 2017 and 2018. Papers have been selected based on their broad impact and balancing between the two major aspects of coatings science and technology: deposition and characterization.

Book Description
This volume chronicles the proceedings of the 9th International Symposium on Particles on Surfaces: Detection, Adhesion and Removal held in Philadelphia, PA, June 2004. The study of particles on surfaces is crucially important in a legion of diverse technological areas, ranging from microelectronics to biomedical to space. This volume contains a total of 21 papers covering many ramifications of particles on surfaces, ranging from detection to removal. All manuscripts were rigorously peer-reviewed and revised, and properly edited before inclusion in this book. The topics covered include: imaging and analysis of macro and nanosize particles and surface features; determination of particles on surfaces; laser inactivation on surfaces; laser-assisted nanofabrication on surfaces; post-CMP cleaning process; pre-gate cleaning; solar panel obscuration in the Martian atmosphere; adhesion and friction of microsized particles; microroughness of textile fibers and capture of particles; factors affecting particle adhesion and removal; various techniques for cleaning or removal of particles from different substrates including laser, combination of laser-induced shockwave and explosive vaporization of liquid, attenuated total internal reflection of laser light, CO2 snow, use of dense phase fluids, use of surfactants and impinging air jet; and removal of sub-100-nm particles.
