This laboratory provides students a basic approach to bioconjugation experiments, a topic which is not typically covered in didactical laboratories. Students are required to characterize a fluorescent probe as well as a protein and then to perform a bioconjugate experiment. The resulting marked protein is characterized by means of UV-Vis spectroscopy.

The chemical vapor deposition is an attractive technique for the growth of thin films and coatings, mainly focused in applications of wear protection, corrosion and microelectronic. This technique has received special attention because allows to deposit thin films and coatings on complex substrates with irregular geometry. The laboratory experiment presented includes a delivery system based on an electro mechanical injector, denominated direct liquid injection, an updated variant of the classical chemical vapor deposition process with the aim of providing a more constant vapor phase for the process. Although it’s numerous advantages, the high price for this equipment represents a barrier for the widespread of this technique in academic environments. The accessible materials used for this experiment setup allows building the setup in laboratories and facilities of universities and research centers focused on nanotechnology and materials science. The experiment setup has been successfully build and is used as a compressive hands-on tool to teach undergraduate, master and doctorate students the direct liquid injection chemical vapor deposition technique.

Organic chemistry textbooks are constantly growing due to the need to include modern material. However, the amount of content is limited by their physical size, which brings up concerns that old, very important, topics will be excluded to make room. To point out this ominous trend, we have tracked the coverage of the topics, petroleum and petroleum chemistry, in organic chemistry textbooks from 1856 to the present day. We have uncovered the troubling trend that, starting in 1970, the coverage of these topics has steadily diminished. Also, through polls we have shown that the general public has very little knowledge of how petroleum shows up in their lives. We imply that there is a connection.
