A crested gecko, Correlophus ciliatus, climbing up the vertical side of a terrarium. The feet of geckos have a number of specializations. Their surfaces can adhere to any type of material with the exception of Teflon (PTFE). This phenomenon can be explained with three elements: Foot structure; Structure of the material to which the foot adheres
The two front feet of a tokay gecko can withstand 20.1 N of force parallel to the surface with 227 mm 2 of pad area, [4] a force as much as 40 times the gecko's weight. . Scientists have been investigating the secret of this extraordinary adhesion ever since the 19th century, and at least seven possible mechanisms for gecko adhesion have been discussed over the past 17
Nano tape, also called gecko tape is a synthetic adhesive tape consisting of arrays of carbon nanotubes transferred onto a backing material of flexible polymer tape. These arrays are called synthetic setae and mimic the nanostructures found on the toes of a gecko ; this is an example of biomimicry .
Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (Gekko gecko) are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened ...
This resulting fouling is a common problem for reversible adhesives modeled after the gecko toe pad. Digital hyperextension, or a movement of the toe with each gecko step, contributes to the self-cleaning. [53] A surface or system that mimics this dynamic self-cleaning process has yet to be developed.
A pair of mannequins in a boat are used to document the annual ice-out on the Wolf River in New London. This year's was earliest in 173 years.
A crossword (or crossword puzzle) is a word game consisting of a grid of black and white squares, into which solvers enter words or phrases ("entries") crossing each other horizontally ("across") and vertically ("down") according to a set of clues. Each white square is typically filled with one letter, while the black squares are used to ...
An acrostic is a type of word puzzle, related somewhat to crossword puzzles, that uses an acrostic form. It typically consists of two parts. It typically consists of two parts. The first part is a set of lettered clues, each of which has numbered blanks representing the letters of the answer.
