Mechanical metamaterials with zero Poisson’s ratio (ZPR) offer unique advantages in applications requiring dimensional stability under large deformations. Here we present a three-dimensional, large ...

The HC976 housed and HC976E embedded helical antennas are designed and crafted for high-accuracy positioning in a light and compact form factor, making them suitable for many applications: autonomous ...

Nature uses pH to control protein assembly. For example, spider silk protein has a pH-sensitive relay to control the generation of solid silk 1, CTP synthase filaments polymerize at low pH to ...

Since the dawn of time, with his interest in combining filaments, strands, fibers, or other elements into thread, yarn, cords, ropes, or lines, these elements have always been twisted together. More ...
