(Nanowerk Spotlight) The colors in the world around us are produced through either absorption of light by molecules (pigmentary colors) or scattering of light by nanostructures (structural colors).

Imagine buying a flat sheet from a furniture store that changes into a sofa when you heat it with a hairdryer. Or consider the value of a stent that precisely expands inside a patient's artery, ...

Painful hypodermic needles may not be needed in the future to give shots, inject drugs and get blood samples. With 4D printing, Rutgers engineers have created tiny needles that mimic parasites that ...

Whilst 3D printing continues to grow in popularity, some scientists are already looking at the next step – how to make their objects transform from one shape to another using 4D printing. Essentially, ...

3D printing, also called additive manufacturing, is rapidly becoming commonplace in all industries, including aerospace, automotive, medical and dental, and consumer and industrial goods. Some ...

(Nanowerk Spotlight) Compared to creating static objects with 3D printing, 4D printing systems add time as the fourth dimension to 3D printing: 4D printing allows a 3D printed structure to change its ...

Painful hypodermic needles may not be needed in the future to give shots, inject drugs and get blood samples. With 4D printing, engineers have created tiny needles that mimic parasites that attach to ...

The days when 3D printing was simply dreamed about are far behind us. Today, the process of creating a three-dimensional object via successive layers of materials is a mainstream activity—from ...
