Designing durable icephobic surfaces

Ice accretion has a negative impact on critical infrastructure as well as a range of commercial and residential activities Icephobic surfaces are defined by an ice adhesion strength τice 100 kPa However the passive removal of ice requires much lower values of τice such as on airplane wings or power lines (τice 20 kPa) Such low τice values are scarcely reported and robust

Fine Tuning of Tissues' Viscosity and Surface Tension

Steinberg et al proposed a long time ago an analogy between liquids and tissues and showed that indeed tissues possess a measurable tissue surface tension and viscosity We question here the molecular origin of these parameters and give a quantitative measurement of adhesion versus contractility in the framework of the differential interfacial

Interfacial Adhesion

02 04 2010Interfacial adhesion occurs when two different materials are combined blended or mixed This combination may create the better dispersion of materials into the matrices Usually to achieve better interfacial adhesion the combination of materials must have the same properties such as hydrophilic fillers and hydrophilic matrices or hydrophobic and hydrophobic materials which creates a

Adhesion

Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another) The forces that cause adhesion and cohesion can be divided into several types The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of
