Quorum Sensing is a biological phenomenon of cellular communication which plays a role in biofilm development or even bacteria colony growth. We emulate this communication by using an analog of urease encapsulated beads subjected to a urea solution.
PHOTOCHEMICAL OXIDATION MASS SPECTROMETRY
A193 nm laser is directed at the electrospray source of a mass spectrometer that contains hydrogen peroxide and a protein. The photogenerated radicals oxidize the protein, enabling ultrafast characterization of its structure.
ELECTROLYTES IN MOTION
The molecular structure and dynamics of electrolytes is important in science and engineering due to their use in electrochemical storage. Time resolved infrared spectroscopic methods are currently the best tools for investigating the electrolytes at the microscopic level, but understanding these liquid systems remains very challenging.
