When the petal of a flower is being formed, its shape is achieved by cells in one area expanding more than cells in an adjacent area. This uneven expansion causes the material to buckle, creating the ...

Experimental and theoretical physicists and a polymer scientist have teamed up to use much thinner sheets than before to achieve seeking to encapsulate droplets of one fluid within another. Thinner, ...

This is a flexible pressure-sensor array. Photograph of the three individual sheets before lamination. Bottom, 125-micrometer-thick PEN (polyethylene naphthalate) sheet with 676 2T memory cells; ...

Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for ...

(Nanowerk News) Materials scientists seeking to encapsulate droplets of one fluid within another often use molecules like soap or micro- or nano-particles to do it. One distinct way of wrapping a ...
