DNA puts Stanford chemists on scent of better artificial nose

A new approach to building an “artificial nose” – using fluorescent compounds and DNA – could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford chemists. If their method lives up to its promise, it could one day detect everything from incipiently souring milk to high explosives.

Thermometry – the measurement of temperature – is critical to a wide range of applications, including many industrial processes, biomedical monitoring, and environmental regulatory systems. However, measuring temperature in the presence of high RF (radio frequency) or other electromagnetic fields – such as are found in aerospace, automotive and medical systems – cannot be accomplished using electrical thermometric probes.

“Valleytronics” – quantum electronics in diamond

deimantas

Diamond is a semiconductor with extreme properties, such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. This makes diamond extreme in the group of wide-bandgap semiconductors, which includes e.g., silicon carbide (SiC) and gallium nitride (GaN).
