New gas sensor chip paves the way to autonomous e-nose

Imec and Holst Centre researchers have developed very sensitive integrated sensing elements for gas detection. The polymer-coated microbridges in high-density arrays can detect ppm-level concentrations of vapors using on-chip ...

MIT researchers harness the sun's power

For decades, scientists have been trying to replicate the process of photosynthesis -- the process by which plants convert sunlight into energy. The Economist reports that Angela Belcher and her colleagues at the Massachusetts ...

Solving the chalk mystery

A piece of chalk in a laboratory at the University of Stavanger in Norway may be the key to unlock a great mystery. If the mystery is solved, it will generate billions in additional income for the oil industry. Associate ...

New research extends classic quantum optics phenomenon

Physicists at the University of Southampton have extended the theory of resonance fluorescence, a classic phenomenon in quantum optics, to 2D nanostructures that have novel light emission properties.

Tiny rulers to measure nanoscale structures

With the advent of nanometer-sized machines, there is considerable demand for stable, precise tools to measure absolute distances and distance changes. One way to do this is with a plasmon ruler. In physics jargon, a "plasmon" ...

Emerging new properties at oxide interfaces

In many ionic materials, including the oxides, surfaces created along specific directions can become electrically charged. By the same token, such electronic charging, or 'polarisation', can also occur at the interface of ...

Team synthesizes georgeite for first time

An international group of researchers has synthesized an extremely rare mineral and used it as a catalyst precursor to improve two reactions that are of great importance to the chemical industry.
