(PhysOrg.com) -- Researchers have fabricated a fluidic antenna that can change its shape, and therefore the frequency at which it resonates, in response to pressure in a controlled and predictable manner. Shape-changing antennas ...
(PhysOrg.com) -- Working out of Tokyo University, scientists in the Department of Materials Science, have developed a new metal alloy that unlike other “superelastic” alloys can resume its original shape in temperatures ...
In recent years, it has become possible to use laser beams and electron beams to "print" engineering objects with complex shapes that could not be achieved by conventional manufacturing. The additive manufacturing (AM) process, ...
