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;

Описание: CRAFT AN EMOTIONALLY CHARGED STORY THAT KEEPS READERS TURNING PAGESHave you ever started writing a story, feeling full of inspiration and enthusiasm, only to lose direction somewhere in the middle?Grab hold of a bright lifeline for writers trekking across their novel's swampy middle. Like Ariadne's thread guiding Theseus through the treacherous labyrinth, there exists a scarlet cord to help successfully navigate from beginning to end.Much more than a "plot point" to energize pacing, the Midpoint is the central nervous system controlling the entire story. Mastering the Midpoint helps writers survive and thrive in the Everglades of the middle. Rediscover the spark in your story by learning how to-- Design a Midpoint with depth by crafting realistic, multi-dimensional character flaws that resonate emotionally with readers.- Strategically position the Midpoint at the apex of a simple four-step story structure that reflects realistic human self-improvement.- Connect the three key events (the Midpoint is one of them ) in every story that are absolutely vital to creating escalating tension.- Translate the eight essential functions of the Midpoint into specific beats and scenes reflecting your unique creative vision.- Apply three quick and easy "tools" to craft Midpoints with maximum dramatic impact.Ignite your creativity while enjoying dozens of examples from novels, television, and movies. Fantasy, inspirational, mystery, science fiction, western, young adult, romantic suspense, and contemporary/historical romance-every genre contributes valuable insights.

Описание: From the highest halls of power to the most remote corners of rural America, featuring amazing technological innovation and an epic battle between the captains of a corrupted industry and America's most politically astute president, here is the story behind the greatest peacetime achievement in US history--the electrification of an entire nation under Franklin Delano Roosevelt When Franklin Delano Roosevelt took office in the depths of the Depression, high tension--or high voltage--power lines had been marching across the country for decades, delivering urban Americans a parade of life-transforming inventions from electric lights and radios to refrigerators and washing machines. But most rural Americans still lived in the punishing pre-electric era, unconnected to the grid, their lives consumed and bodies broken by backbreaking chores. High Tension is the story of Franklin Delano Roosevelt's battle against the "Power Trust," an elaborate Wall Street-controlled web of holding companies, to electrify all of America--even when the corrupt captains of the industry and their cronies (led by a formidable and honest champion, Wendell Willkie, whose role in the battle propelled him to a presidential bid to unseat Roosevelt in 1940) cried that running lines to rural areas would not be profitable and that in a free market there would simply have to be a divide between the electricity haves and have-nots. FDR knew better, and in this story of shrewd political maneuvering, controversial legislation, New Deal government organizations like the Tennessee Valley Authority, the packing of the Supreme Court, towering business figures, greedy villains, and the crying needs of farmers and other rural citizens desperate for services critical to their daily lives John A. Riggs has chronicled democracy's greatest balancing act of government intervention with private market forces--one that brought affordable electricity to all Americans, powered the industrial might that won World War II, and established a model for public-private solutions today in areas such as transportation infrastructure, broadband, and health care.

Surface tension provides a thermodynamic avenue for analyzing systems in equilibrium and formulating phenomenological explanations for the behavior of constituent molecules in the surface region. While there are extensive experimental observations and established ideas regarding desorption of ions from the surfaces of aqueous salt solutions, a more successful discussion of the theory has recently emerged, which allows the quantitative calculation of the distribution of ions in the surface region. Surface Tension and Related Thermodynamic Quantities of Aqueous Electrolyte Solutions provides a detailed and systematic analysis of the properties of ions at the air/water interface.
Unifying older and newer theories and measurements, this book emphasizes the contributions of simple ions to surface tension behavior, and the practical consequences. It begins with a general discussion on Gibbs surface thermodynamics, offering a guide to his theoretical insight and formulation of the boundary between fluids. The text then discusses the thermodynamic formulae that are useful for practical experimental work in the analysis of fluid/fluid interfaces. Chapters cover surface tension of pure water at air/water and air/oil interfaces, surface tension of solutions and the thermodynamic quantities associated with the adsorption and desorption of solutes, and surface tension of simple salt solutions. They also address adsorption of ions at the air/water interface, surface tension of solutions and the effect of temperature, adsorption from mixed electrolyte solutions, and thermodynamic properties of zwitterionic amino acids in the surface region. Focusing on the thermodynamic properties of ions at air/fluid interfaces, this book gives scientists a quantitative, rigorous, and objectively experimental methodology they can employ in their research.
