Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a ...

As regulatory initiatives increasingly call for an understanding of the cumulative risks from chemical mixtures, evaluating exposure data from large biomonitoring programs, which may inform these ...

A computer simulation shows metallic alloy where atoms (colored spheres) are arranged in subtle chemical patterns beneath a network of dislocations (green lines). These tangled defects move during ...

Directed self-assembly (DSA) is a nanofabrication technique in which self-assembling block copolymer thin films (BCP) are ordered using larger-scale, pre-defined guides patterned by standard ...

A chemical computer made from a network of enzymes can perform a variety of tasks, like measuring temperatures or identifying substances, without needing to be rebuilt each time. This makes it more ...

A logarithmic spiral with a diameter of 500 μm, approximately half the diameter of a sewing needle. Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led ...
