A New Generation Of Super Duct Tape With Capacity For Independent Clean

The gecko on the wall holds on and be quiet， as a piece of cement adhere to the wall. The scientist Metin Sitti from the Carnegie Mellon University of America and his team found in the research that each toe of the gecko has millions of cilium on it， which are in micron order and look like bristles. The ends of these cilium have interactions with the climbing surface via the electrical attraction called “van der Waals force”. Just through this attraction， The gecko resists gravity， and climbs on the surface of any kind of material at random. This team gained inspiration from this and exploited a kind of multifunctional super duct tape with capacity for independent clean.

The adhesive on this duct tape uses a kind of fiber， whose operating principle is similar to the cilium of geckos toes. The fiber is make of elastomeric polymer， fiber.A new generation of super duct tape with capacity for independent clean， the light-colored matters in the image are dust particles， on the lift is clean fiber， the end of the geckos toe is in the shape of a small mushroom head， which can be closely glued to the surfaces of matters. The fibers are arranged equably in the grid array， and form a sticky area， which looks like the scotch tape in our daily life. Meanwhile， if you paste and tear off the duct tape for several times on a clean surface， the dust particles at the end of the fiber will be cleaned up， which means you increase the life span of the tape. However， the fiber on this duct tape could clean up big dust particles at present. The team is planning to exploit the microfiber of submicron order， in order to better clean up more tiny dust particles.

History

On May， 6th， 1856， Sigmund Freud was born in a Jewish family of Austria. Freud entered the medical college of University of Vienna to learn neuromedicine when he was 17. He participated a project in curing a patient with hysteria together with Joseph Breuer when he was 28. And from then on， he turned the core of his academic career from clinical neurology to pathergasiology. In 1900， Freuds work “Interpretation of Dreams” was published， which opened up a new page in the realm of psychological research. In 1905， Freud published three important works continuously， which explained mental symptoms by dreams， discussed the motive and manifestation of consciousness， explored the sexual instincts human had in different age brackets. Freud had put forward the theory of personality trait， initiated the psychoanalytic school in his life. Beginning with him， people entered the new era in exploring the psychology.
