According to an article in Physics Today a team of researchers from Stanford University, UCLA and other 9 universities, laboratories and medical schools have collaborated in the creation of a microfluidic chip that demonstrates the possibility of a multistep organic synthesis on a single chip microfluidics.
The device produces 2-deoxy-2-[18F] fluoro-D-glucose (FDG), a radiopharmaceutical tracer used in positron emission tomography.

The bites are one of the most destructive forms of corrosion as a potential cause of failure of equipment due to perforation and / or penetration. These usually occur in areas protected by metal oxide coatings such as stainless steel, aluminum, etc.. Typically in boiler water systems and supply, increased risk of pitting corrosion increases dramatically with increasing content of oxygen in the fluid.
Stings can occur in any metal surface.
Corrosion Mechanism
In the figure below, the oxygen abundance in the liquid comes into contact with the metal surface thus becomes a cathode (top). At the bottom, the low oxygen level that party becomes an anode. This will form a complete circuit where the metal is ionized to release an electron and to form the ion Fierro (FE2 +), this electron will move to the top to react with oxygen (O2) (and water, H2O) to form ions hydroxide form (OH-). Iron ion (Fe2 +) react with hydroxide ions (OH-) to form Iron Oxide (Fe2O3) that is typically a brown rust.
