Abstract: A mass analyzing apparatus and system are disclosed for time-of-flight (“TOF”) mass spectrometry analysis. A representative system includes a first electrostatic mirror prism to reflect a first ion beam and provide an intermediate ion beam having an intermediate TOF focus and having a spatial dispersion of ions proportional to ion kinetic energies; and a second electrostatic mirror prism to reflect the second ion beam and converge the spatial dispersion of ions to provide a third, recombined ion beam having an output TOF focus; and an ion detector arranged at the output TOF focus to receive and detect the ions of the third ion beam. A bandpass filter may be arranged at the intermediate TOF focus to selectively allow propagation of ions of the second ion beam having a selected range of ion kinetic energies. Configurations having additional electrostatic mirror prisms are disclosed, including for tandem MS-MS and selectable time-of-flight.

Abstract: The present invention provides a method of producing a nanocomposite film on a substrate. The method involves co-deposition of gaseous lead salt clusters in a conducting polymer film, such as a conductive polythiophene, on the substrate. The polymer film preferably is simultaneously deposited with the lead salt clusters, e.g., by co-depositing organic monomers and/or oligomers onto the substrate in the presence of gaseous lead salt clusters. Preferred lead salts are PbS, PbTe and PbSe. Devices and articles of manufacture including a nanocomposite film of the invention are also disclosed.

Abstract: Conducting polymers having improved optical properties, and a method of manufacturing the conducting polymers, are disclosed. The conducting polymers are prepared by a process wherein organic ions and neutral oligomers are deposited simultaneously on a substrate surface to provide a conducting polymer film.

Abstract: The present invention provides a novel substrate for use in growing cells and for the study of mechanobiology. The membrane of the present invention comprises appropriate microtopography and surface chemical modifications to facilitate the production of adherent and oriented cells that phenotypically resemble cells in vivo.
