WebIn this channel all information related to mechanical field i.e. theory , numerical problems and what ever you required related to mechanical. WebConventional lab testing platforms to determine the efficacy of trial pharmaceutical drugs on cells are inefficient at screening out failure candidates. Electro wetting-on-dielectric … Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together. This happens in presence of a gaseous phase or another liquid phase not miscible with the first one. The degree of wetting (wettability) is … Meer weergeven Adhesive forces between a liquid and solid cause a liquid drop to spread across the surface. Cohesive forces within the liquid cause the drop to ball up and avoid contact with the surface. The Meer weergeven Unlike ideal surfaces, real surfaces do not have perfect smoothness, rigidity, or chemical homogeneity. Such deviations from ideality … Meer weergeven If a drop is placed on a smooth, horizontal surface, it is generally not in the equilibrium state. Hence, it spreads until an equilibrium contact radius is reached (partial wetting). While taking into account capillary, gravitational, and viscous contributions, … Meer weergeven • Adsorption – Phenomenon of surface adhesion • Amott test • Anti-fog – Chemicals that prevent the condensation of water as small … Meer weergeven Liquids can interact with two main types of solid surfaces. Traditionally, solid surfaces have been divided into high-energy and low-energy solids. The relative energy of a solid has to … Meer weergeven An ideal surface is flat, rigid, perfectly smooth, chemically homogeneous, and has zero contact angle hysteresis. Zero hysteresis implies the advancing and receding contact angles are equal. In other words, only one thermodynamically stable contact … Meer weergeven Surfactants Many technological processes require control of liquid spreading over solid surfaces. When a drop is placed on a surface, it can completely wet, partially wet, or not wet the surface. By reducing the surface … Meer weergeven is the bahamas in the southern hemisphere
