Sentences with phrase «adhesive forces»

Using harnesses, a machine and a measuring device to pull these discs off different textured surfaces, they found that the clingfish's disc can generate adhesive forces 80 to 230 times their body weight, allowing this tiny fish to hang onto rocks, and to hunt limpets (round molluscs that also cling to rocks).

«As a result, the small amount of wet mucus between these protrusions provides adhesive forces.»

These temporary adhesive forces happen because electrons orbiting the nuclei of atoms are not evenly spaced, creating a slight electrical charge.

The increased stiffness plays an important role in enabling larger geckos to produce sufficient adhesive forces to climb, the authors say.

It's one of the strongest adhesive forces in nature.»

Higham and Russell are planning to travel to French Guiana to do empirical adhesive force studies on living geckos in native forests.

The researchers incorporated ecological observations, adhesive force measurements, and body size and shape measurements of museum specimens to conduct simulations.

When the molecules are dissimilar, as in the case of a glue molecule and a molecule of the substrate (the surface the glue is sticking to), the adhesive force holds the glue to the substrate.

«The key feature of our material is the combination of a very strong adhesive force and the ability to transfer and dissipate stress, which have historically not been integrated into a single adhesive,» says corresponding author Dave Mooney, Ph.D., who is a founding Core Faculty member at the Wyss Institute and the Robert P. Pinkas Family Professor of Bioengineering at SEAS.

Not exact matches

The adhesive provides additional grip compelling drivers to fight tooth - and - nail to stay on the bottom, essentially forcing them to use their front bumpers to nudge a competitor aside and complete a pass.

This increased grip state strengthens the traction force produced by the axon onto the adhesive substrate, allowing the axon to turn and change its direction on cue.

The new study by the Inagaki lab showed that neurons will produce four times more traction force when placed on adhesive substrates coated with laminin than those without laminin, assuring the axons reach their final destination.

Secondly, the researchers focused on distributing forces on surfaces that aren't flat to optimize the performance of gecko - inspired adhesives.

The researchers found a way to distribute force along a soft, flexible gripper, while maintaining the manufacturing precision required for the adhesives.

When he and his team took a look at the ivy's glue with a powerful atomic - force microscope, they were able to identify a previously unknown element in its adhesive.

Temporary shifting of the electrons in the molecules of the spatulae and of opposing rocks, walls, or ceilings creates adhesive van der Waals forces, according to a study in the Aug. 27 Proceedings of the National Academy of Sciences.

The study, recently published in the Journal of the Royal Society Interface, reports there are circumstances — such as when geckos fear for their lives, leap into the air and are forced to grab on to a leaf below — when they need every bit of that fabled adhesive ability, and sometimes it's not enough.

«The paper shows that [adhesive capability] might be exaggerated, because geckos experience falls and a necessity to grip a surface like a leaf that requires a much more tenacious adhesion force; the paper shows that in some cases the adhesive ability can be exceeded,» Niklas said.

To get the gripper to stick to a surface, force is applied to the adhesive pad material in a manner that makes the hairs bend.

Specific adhesion includes electrostatic forces, van der Waals forces and acid - base interactions that take place between the adhesive and the substrate.

To find out whether the suckers provide a tighter grip, a research team removed legs from sedated male diving beetles and measured the force required to pry the adhesive structures from smooth surfaces.

Normal adhesives stop being sticky in the cold vacuum, and the force required to attach a piece of sticky tape is enough to make the target object float away.

This is new - fangled cleaning with physics using nothing but the adhesive power of forces — cleaning mechanically and without chemicals.

Rumors or gossip can connect the private and public spheres, they manipulate and have a psychological effect, they are social adhesives and a driving force of the art world, a community that functions according to its own rules.

James Park, Fitbit CEO and co-founder, said the allergic reactions appeared to have been triggered by the methacrylates that were mixed into the Force's adhesives, attributing adverse reactions to nickel to a lesser role.
