World's highest-performance single-molecule diode created

As electronics miniaturization heads towards a theoretical physical limit in the tens of nanometers, new methods of manufacturing are required to produce transistors, diodes, and other fundamental electronic components. In this vein, a new range of molecule-sized devices have been created in the laboratory, though with varying results in terms of efficiency and practicality. Now a group of researchers from Berkeley Lab and Columbia University claims to have created the highest-performing, single-molecule diode ever made, which is said to be 50 times better in performance and efficiency than anything previously produced.

Finnish tech could let smartphones "see" gas

Smartphones are already able to monitor things such as light, sound, movement and geographical location. Soon, airborne gases could be added to that list. That’s because VTT Technical Research Centre of Finland has developed a miniature phone-compatible sensor, that uses light to identify the type and amount of gases in air samples.
