Stacks on stacks on stacks

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.

Can adding calcium help forests?

This study further supports a connection between acid deposition and forest decline. The authors state, “Continued vigilance in the control of acid rain precursors will be needed to correct these problems, and aggressive options to reduce pollution in rapidly industrializing regions of Latin America, Asia, and Africa are warranted.”

Questions are raised about “unclick” reaction

Click chemistry, a term used to describe a number of high yield reactions, is used far and wide by chemists. The azide alkyne Huisgen cycloaddition typifies click chemistry and awhile back, I described it as my favorite reaction.

Safety in Academic Labs

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,…

Update to “Women and Named Reactions”

    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…

Reader Survey

Please help Chembites become a better resource by taking our Reader Survey! It should be quick (~5 min) and painless.

Your answers will help us develop our features, posts, and ultimately decide where Chembites goes in the future.

Thinking about summer? Think about an REU!

I really can’t praise REU programs enough. You get paid (most programs give a stipend and pay for housing) for an amazing experience, both in terms of the research and the chance to travel to really interesting parts of the US and the world. And remember, if you are applying to grad school, undergraduate research is a necessity, so take advantage of these wonderful programs!
