Diffusion-Based Biosensing Approach in Miniaturized Lab-on-a-Chip Devices
Published Thursday, September 6, 2012BackgroundElectrochemical impedance spectroscopy (EIS) biosensors are very sensitive to small electrochemical changes at the solid-electrolyte interface. EIS-based DNA biosensors detect any hybridization events that occur at the interface of an electrode, because such events change the total net charge at the interface of the electrode...

Low Temperature Synthesis of Faceted Aluminum Nanocrystals
Published Monday, March 26, 2012Metal/oxidizer combinations make very powerful energetic materials due to their high total energy content compared to CHNO-based materials. Bulk aluminum has a very high energy density when oxidized to alumina, but problems arise for energetic applications because the kinetics are diffusion limited between oxidizer and aluminum. This is partially...
