Learn More· This work extends gecko-inspired adhesives from primarily unidirectional grasping to general manipulation with multifingered hands ( Fig. 1 ). The extension rests upon the combination of a strong, selectively stiff multiphalangeal hand with three adhesive principles: high contact area, shear load sharing between contact patches, and even normal
Learn More· It is important for quantitative work to operate in a range in which a plot of assay signal (often absorbance) versus enzyme concentration is linear. Most assays are linear if the degree of substrate conversion is less than 15%, assuming that there are no other limiting factors. By fixing the assay time ( 30 min) and temperature ( 25oC) the degree of conversion …
