DNA design brings predictability to polymer gels

Scientists in Japan have made a tuneable, elastic and temperature-sensitive gel by using complementary DNA strands to connect star-shaped polymer molecules together. The gel, and the method used to develop it, could lead ...

Speed of sound used to measure elasticity of materials

Researchers at the University of Nottingham have devised a revolutionary new technique for measuring the microscopic elasticity of materials for the first time. Known as SRAS, the technology works by measuring the speed of ...

New technique acts as accelerator, brake for microscopic droplets

A miniscule water droplet is on the move, picking up speed as it glides along a stretch of thin, flat terrain. Abruptly, it hits a rough patch—the microscopic equivalent of glass speed bumps into which the droplet settles ...

3D shape reconfiguration of stretchable electronics

Azobenzene functionalized liquid crystalline polymers are considered "smart" materials owing to their programmable shape transformations under various external stimuli (i.e., thermal, chemical, and photomechanical shape morphing). ...

Elasticity

Elasticity may refer to:

Numerous uses are derived from this physical sense of the term, which is inherently mathematical, such as used in Engineering, Chemistry, Construction and variously in Economics:
