Biological Surface Science

Surface Science evolved from the need to understand interfaces in semiconductor manufacturing and heterogeneous catalysis, and relied heavily on model surfaces mimicking specific aspects of the more complex "real" surfaces of technological relevance. Most methods to characterize the structure and composition of surfaces with atomic precision traditionally required a vacuum environment, if not for the probes used (electrons, ions, atoms...), then to avoid contamination of the surfaces from an ambient atmosphere.

Novel NMR/MRI Modalities: Radiation-free NMR and MRI and Quadrupolar MRI

Novel NMR/MRI Modalities: Radiation-free NMR and MRI and Quadrupolar MRI A. Jerschow Department of Chemistry, New York University, New York, NY 10003 NMR spectroscopy and magnetic resonance imaging (MRI) rely on the application of radiofrequency (rf) irradiation in combination with a static magnetic field. Rf irradiation may lead to heating and other, yet unknown bioeffects. Spin-noise detection does not require any form of rf irradiation, the availability of strong magnetic fields, nor large population differences between the nuclear spin states.
