Capillarity-based switchable adhesion.
Drawing inspiration from the adhesion abilities of a leaf beetle found in nature, we have engineered a switchable adhesion device. The device combines two concepts: The surface tension force from a large number of small liquid bridges can be significant (capillarity-based adhesion) and these contacts can be quickly made or broken with electronic control (switchable). The device grabs or release...
متن کاملUse of Barbed Sutures in Laparoscopic Gastrointestinal Single-Layer Sutures
BACKGROUND AND OBJECTIVES Laparoscopic anastomotic methods are not commonly used because of the cumbersome laparoscopic intracorporeal sutures and tying involved. The barbed suture is one of the various devices developed to simplify the placement of intracorporeal sutures. However, barbed sutures are not commonly used during reconstruction after radical gastrectomy in cancer patients or for sin...
متن کاملCapillarity - Mediated Grain Growth in 3 - D
Space-filling in kinetically active 3-d network structures, such as polycrystalline solids at high temperatures, is treated using topological methods. The theory developed represents individual network elements—the polyhedral cells or grains—as a set of objects called average N -hedra, where N , the topological class, equals the number of contacting neighbors in the network. Average N -hedra sa...
متن کاملCapillarity and dynamic wetting
In this thesis capillary dominated two–phase flow is studied by means of numerical simulations and experiments. The theoretical basis for the simulations consists of a phase field model, which is derived from the system’s thermodynamics, and coupled with the Navier Stokes equations. Two types of interfacial flow are investigated, droplet dynamics in a bifurcating channel and spontaneous capilla...
متن کاملThe sutures in dentistry.
In oral surgery, the last phase of a surgical operation is represented by the tissues suture, that allows the wound lips edges approximation and their stabilization, to promote haemostasis, to avoid the alimentary residues accumulation on the incision line and allow the first intention healing. A good suture avoids that the displacing forces generated by the muscular insertions, functional move...
