(Phys.org)—In 1959 Moore observed that from the time the integrated circuit was invented, the number of transistors per square inch doubled about every eighteen months. A contemporary of Moore, Feynman, suggested that denser ...
Dartmouth researchers have developed a molecular switch that changes a liquid crystal's readout color based on a chemical input. This new development may open the way for using liquid crystals in detecting harmful gases, ...
