Proton pack Proton pack The proton pack is an energy weapon used for weakening ghosts and aiding in capturing them within the "Ghostbusters" universe. First depicted in the film "Ghostbusters", it has a hand-held wand ("Neutrona Wand" or particle thrower) connected to a backpack-sized particle accelerator. It fires a stream of highly focused and radially polarized protons that electrostatically traps the negatively charged energy of a ghost, allowing it to be held in the stream. The proton pack, designed by Dr. Egon Spengler, is a man-portable particle accelerator system that is used to create a charged particle beam—composed of protons—that is fired
Pictet–Spengler reaction imine generated from the condensation of the aldehyde and amine. This helps to explain the need for an acidic medium in some substrates, as the imine may not be electrophilic enough for ring closure to occur but the Iminium ion is capable of undergoing the reaction. The Pictet-Spengler reaction is widespread in both human industry and biosynthesis. It has remained an important reaction in the fields of alkaloid and pharmaceutical synthesis since its inception, where it has been employed in the development of many beta-carbolines. The enzyme strictosidine synthase is an example of nature utilizing the Pictet-Spengler reaction, which generates
