Have you ever played with Rose’s metal? It’s a fusible alloy of bismuth, lead, and tin with a low melting point of around 100 °C. Historically, it’s been used as a solder for cast iron railings and ...

Gravity casting aluminum in permanent molds beats conventional sand and pressure die casting. Today, gravity-fed permanent metal molds can produce near-net-shape parts from a variety of aluminum ...

Researchers have developed a low-cost, easy way to make custom lenses that could help manufacturers avoid the expensive molds required for optical manufacturing. Researchers from Washington State ...

EPFL researchers have engineered a fiber-based electronic sensor that remains functional even when stretched to over 10 times ...

Researchers show that switching between reflective and scattering states can be achieved with just 1.4 V, about the same voltage used to light a typical LED. Researchers have developed a way to ...
