Finding ways to create order is a common theme in science. Here researchers are trying to carefully arrange chromophores in order to create better solar cells (among other potential uses). In particular, these chemists are trying to make porphyrins stand up on a surface creating stacks of porphyrins that are a well defined distance from each other and from the surface they are attached to.
Here the authors describe all of the consumer products that are utterly and completely chemical-free. I hate to ruin the surprise, but their aren’t any.
The Sheri Sangji case at UCLA is a horrible tragedy and confronts an uncomfortable topic for many chemists – safety in academic labs. Often with professors pushing students to complete work as fast as possible proper safety precautions are not taken, people are not trained well, and tragedies can occur. ChemBark made a post this … Continue reading

Paper-Based Blood Typing Device That Reports Patient’s Blood Type “in Writing” Li, M.; Tian, J.; Al-Tamimi, M.; Shen, W. Angew. Chem. Int. Ed. 2012 DOI: 10.1002/anie.201201822 Summary: What’s your blood type? Chances … Continue reading
The cocoons, the silkworm itself, and the produced silk become colored when dye is incorporated into the silkworm feed. The concentration of dye in the produced silk changes based on how hydrophobic the dye is (increasing partition coefficient). Continue reading
This paper is an exciting step towards mimicking the conformational changes observed in natural proteins without loss in solubility. Continue reading
Accounts of Chemical Research recently published some additions and corrections to their article “Named Reactions Discovered and Developed by Women.” They were informed of another reaction unambiguously named for a woman – the Catellani reaction. Prof. Marta Catellani of the University of Parma reported the reaction (a coupling of an aryl iodide, an … Continue reading
