LED candles are neat, but they’re very suboptimal for wish-making: you can’t blow them out. Unless you take the circuit from ...

Odds are, if you like neon lights, you’re not thrilled with the LED faux-“neon” strips that are supposed to replace them.

Since the drive for thin-film-transistor LCDs began in the 1980s, these devices have become kings of the display world. But hot on their tails is a whole host of alternative technologies. From digital ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

Abstract: Herein, we present printable indium tin oxide (ITO) based transistors, which serve for implementing a highly secure deoxyribonucleic acid (DNA) cryptosystem. The devices are encoded into DNA ...

Abstract: A new charge-trapping nonvolatile memory (NVM) with a fully same structure to thin-film transistor (TFT) is investigated. Different from the conventional NVM with block layer/charge-trapping ...
