From the reaction to the final product.
The “large” flasks were the place where the reaction happened, the smaller glass is the place to hold the pure product after workup and purification and the small vials are for GC/MS samples to verify the purity of the compounds produced.
A reaction product under UV light.
Even through it contains at least 5 compounds and the one that I need, only formed in a maximum 5%, it still looks great under UV light.
An UV reactor in operation.
Photochemistry is chemical reactions that proceed with the absorption of light by atoms or molecules. This light what was needed for the reaction was generated by a low pressure mercury vapor lamp what mainly emit at 254 nm.
Theoretical study suggests that ions with the same charge might actually become attracted to each other at an interface
One of the most simple tests to show an organic compound present in a reaction mixture is irradiating the sample with UV light. If you know, that the product of the reaction should fluorescence blue, while the starting materials do not emit any light after irradiating the sample with UV, could help a lot while doing a reaction.
In this case a side product formed from the reaction above 130 °C, while the desired product formed at 100 °C. The starting material and the product did not emit any light under UV, while the side product did. So after taking the picture, I was sure, that the reaction is ready.

Explanation: Jewels don’t shine this bright — only stars do. Like gems in a jewel box, though, the stars of open cluster NGC 290 glitter in a beautiful display of brightness and color. The photogenic cluster, pictured above, was captured recently by the orbiting Hubble Space Telescope. Open clusters of stars are younger, contain few stars, and contain a much higher fraction of blue stars than do globular clusters of stars. NGC 290 lies about 200,000 light-years distant in a neighboring galaxy called the Small Cloud of Magellan (SMC). The open cluster contains hundreds of stars and spans about 65 light years across. NGC 290 and other open clusters are good laboratories for studying how stars of different masses evolve, since all the open cluster’s stars were born at about the same time.
To test a new technology for landing heavy payloads on Mars, NASA is about to drop a flying-saucer shaped vehicle from a helium balloon high above Earth’s surface.
The end of a decomposed/polymerized silicone oil.
If someone puts water/acids/gunk in heated silicone oil, it will give a cross linked polymer what will behave as a gunk and not like an oil, as seen on the picture. Do not try it out.

Molecular vibration by danceroom Spectroscopy (dS)
A Royal Society of Chemistry sponsored event to introduce molecular vibration to year 9 students. Danceroom Spectroscopy (dS) is a unique interactive dome experience created by Dr David Glowacki.
