Surface Tension

After witnessing an act of domestic terrorism while training on his bike, Jake is found near death, with a serious head injury and unable to remember the plane crash or the aftermath that landed him in the hospital. A terrorist leader’s teenage daughter, Betsy, is sent to kill Jake and eliminate him as a possible witness. When Jake’s mother blames his head injury for his tales of attempted murder, he has to rely on his girlfriend, Laurissa, to help him escape the killers and the law enforcement agents convinced that Jake himself had a role in the crash. Mike Mullin, author of the Ashfall series, delivers a gripping story with memorable characters and all-too-real scenarios.

This edited volume offers complete coverage of the latest theoretical, experimental, and computer-based data as summarized by leading international researchers. It promotes full understanding of the physical phenomena and mechanisms at work in surface and interfacial tensions and gradients, their direct impact on interface shape and movement, and their significance to numerous applications. Assessing methods for the accurate measurement of surface tension, interfacial tension, and contact angles, Surface and Interfacial Tension presents modern simulations of complex interfacial motions, such as bubble motion in liquids, and authoritatively illuminates bubble nucleation and detachment.

Surfaces are often held to be of lesser consequence than 'deeper' or more 'substantive' aspects of artworks and objects. Yet it is also possible to conceive of the surface in more positive terms: as a site where complex forces meet. Surfaces can be theorized as membranes, protective shells, sensitive skins, even thicknesses in their own right. The surface is not so much a barrier to content as an opportunity for encounter: in new objects, the surface is the site of qualities of finish, texture, the site of tactile interaction, the last point of contact between object and maker, and the first point of contact between object and user. Surface Tensions includes sixteen essays that explore this theoretically uncharted terrain. The subjects range widely: domestic maintenance; avant-garde fashion; the faking of antiques; postmodern architecture and design; contemporary film costume. Of particular emphasis within the volume are textiles, which are among the most complex and culturally rich materialisations of surface. As a whole, the book provides insights into the whole lifecycle of objects, not just their condition when new.

A quick reference to basic science for anaesthetists, containing all the key information needed for FRCA exams.

During the summer vacations of his thirteenth through his sixteenth year, which he spends at his family's lake cottage, Luke realizes that although some things stay the same over the years, many more change.

ALIEN KILLERS! MUTATED SEA MONSTERS! HUMANITY¡¯S LAST GASP! Months after mysterious corals drew 99% of humanity into the sea, a band of survivors ekes out a hollow existence on a remote British island. When two people are cast up on the beach, completely blue, but very much alive, the island is thrown into turmoil. What caused the mass extinction event? How did these two return from the deep, when billions died? Most importantly, what is the coral, and what does it want with the Earth? The creeping, psychological horror fable that became a critical hit, the complete Surface Tension saga, finally collected!

This book describes how surface tension effects can be used by engineers to provide mechanical functions in miniaturized products (1 mm). Even if precursors of this field such as Jurin or Laplace already date back to the 18th century, describing surface tension effects from a mechanical perspective is very recent.brThe originality of this book is to consider the effects of capillary bridges on solids, including forces and torques exerted both statically and dynamically by the liquid along the 6 degrees-of-freedom.brIt provides a comprehensive approach to various applications, such as capillary adhesion (axial force), centering force in packaging and micro-assembly (lateral force) and recent developments such as a capillary motor (torque).

Building on advances in miniaturization and soft matter, surface tension effects are a major key to the development of soft/fluidic microrobotics. Benefiting from scaling laws, surface tension and capillary effects can enable sensing, actuation, adhesion, confinement, compliance, and other structural and functional properties necessary in micro- and nanosystems. Various applications are under development: microfluidic and lab-on-chip devices, soft gripping and manipulation of particles, colloidal and interfacial assemblies, fluidic/droplet mechatronics. The capillary action is ubiquitous in drops, bubbles and menisci, opening a broad spectrum of technological solutions and scientific investigations. Identified grand challenges to the establishment of fluidic microrobotics include mastering the dynamics of capillary effects, controlling the hysteresis arising from wetting and evaporation, improving the dispensing and handling of tiny droplets, and developing a mechatronic approach for the control and programming of surface tension effects. In this Special Issue of Micromachines, we invite contributions covering all aspects of microscale engineering relying on surface tension. Particularly, we welcome contributions on fundamentals or applications related to: Drop-botics: fluidic or surface tension-based micro/nanorobotics: capillary manipulation, gripping, and actuation, sensing, folding, propulsion and bio-inspired solutions; Control of surface tension effects: surface tension gradients, active surfactants, thermocapillarity, electrowetting, elastocapillarity; Handling of droplets, bubbles and liquid bridges: dispensing, confinement, displacement, stretching, rupture, evaporation; Capillary forces: modelling, measurement, simulation; Interfacial engineering: smart liquids, surface treatments; Interfacial fluidic and capillary assembly of colloids and devices; Biological applications of surface tension, including lab-on-chip and organ-on-chip systems.
