Time for Theory

Chemistry is indeed an interplay of experiment and theory. Nowadays, with thousands of chemists working in front of computers, the definition of a lab goes beyond its original boundaries.

Made in Germany: The German Democratic Republic (GDR) and Western Germany united in a lab

Glassware and its cleaning are the main part of a normal lab day for a chemist. You will find it “Made in Germany” all over the world, even in a lab in Australia, where this picture was taken.

The amazing dancing floor

A droplet of water bouncing on a superhydrophobic and light-emitting surface. To the left, a static water droplet looks on and wants to mimic it. The latter will become a awesome dancer very soon.

This multifunctional coating, which combines superhydrophobicity and luminiscence, is based on polyfluorene and silica nanoparticles. It has been used to coat glass and celullose supports and maybe the basis for future highly hydrophobic electronics.

Caffeine–salicylic acid co-crystal

Dissolving caffeine and salicylic acid in acetonitrile and leaving the solution overnight gives this type of co-crystal the next morning.

Water bead ‘molymod’

A ‘molymod’ style structure of a fluorocarbon made by using beads of colored water to represent the carbon and fluorine atoms. This has been carried out on a piece of fabric which has been treated with a fluorocarbon rendering it water repellent.

Checking the Vacuum

Thin layer Chromatography (TLC) of Indole.
Here the TLC plate was developed using two different stains: 1) in an iodine chamber, which results in a brown spot on TLC plate. This is due to complexation between iodine and indole. 2) By spraying Ehrlich’s reagent which results in a purple spot. This is due to a reaction of Ehrlich’s reagent with indole.

Laboratory Fumehood for Homogeneous Catalysis Experiments

A sudden idea related to a mechanism emerges during an experiment. Unfortunately, you have nothing to write on except “the hood”. Sometimes inspiration gets the best of you and there is no time to waste! The beauty of chemistry comes from our creativity and imagination, allowing us to push even further the limits of our knowledge and therefore our curiosity.
