Many electronic circuits require a voltage higher than that available from the power supply. For example, when only a 12V battery or adaptor is available but a circuit requires 20V to 24V, a ...
AF114 germanium transistors and related ones like the AF115 through AF117 were quite popular during the 1960s, but they quickly developed a reputation for failure. This is due to what should have made ...
Scientists have engineered a nanoscale switch using DNA "origami." Inspired by macroscale mechanical switches, the device achieves long-term functionality without the continuous forcing mechanism that ...
