Scientists Say: Metal

These substances conduct electricity and heat, can be shaped and are often shiny. Metal (noun, “MET-al”) Metals are substances that have three major things in common. First, they can conduct electricity and heat. Metals can also be shaped. Some are hammered into flat sheets or can be pulled into wires. Finally, metals are often lustrous […]

Peptides self-assemble to support growth of artificial tumours

Cancer cells grown around bioengineered microfibres make an ideal model to test new chemotherapy drugs The habitat that cells live and grow in has been recreated using a mixture of self-assembling peptides and natural proteins.1 This synthetic matrix was then used to grow cancer spheroids, which could be used to test new anticancer treatments. The […]

Stretching liquid crystals to the limit with LC AuxeTec

The unintuitive properties of LC AuxeTec’s materials mean they thicken when stretched, and could be exploited in body armour and skyscraper windows Auxeticity – the tendency of a material to become thicker rather than thinner when stretched – is an unusual phenomenon. While the property is uncommon, it’s not unheard of. LC AuxeTec, a new […]
