Scanning transmission electron microscopy is utilized to reveal atomic‐level interactions that occur during thermal processing at thin film oxide‐metal interfaces, as described by J. L. Jones and ...co‐workers in article 1500181. These observations, combined with in situ X‐ray diffraction and theoretical techniques, are used to determine how solution‐processed lead zirconate titanate (PZT) films nucleate on Pt electrodes, results that will guide future ferroelectric film processing.
A PC version of three-dimensional molecular graphics package has been developed to run under MS-DOS environment on IBM PC-compatible computers equipped with a VGA graphics board. The program consists ...of two parts: a menu-driven interactive system module in EGA mode, and a ray-tracing module in VGA mode. In the 256-color VGA mode, ray-tracing images are represented with a 4-color map, with 64 levels for each color: 32 levels of illuminance and 32 levels of saturation. Molecular structure can be analyzed along various directions with various light sources. Ray-tracing images are also represented in a 16-color EGA mode with the half-toning method, which can display 76 gray levels for each color. To obtain good photo-realistic images in an efficient way, we have used two light sources, with an intensity ratio of 7:3, which are located in front of the top right and bottom left corners of the screen.
