摘要： Nowadays, tomography plays a central role In pureand applied science, in medicine, and In many brandies of engineering and technology. It entails reconstructing the three-dimensional (3D) structure of an object from a tilt series of two-dimensional (2D) images. Its origin goes back to 1917, when Radon showed mathematically how a series of 20 projection images could be converted to the 3D structural one. Tomographic X-ray and positron scanning for 3D medical imaging, with a resolution of similar to 1 mm, is now ubiquitous in major hospitals. Electron tomography, a relatively new chemical tool, with a resolution of similar to 1 nm, has been recently adopted by materials chemists as an invaluable aid for the 3D study of the morphologies, spatially-discriminating chemical compositions, and defect properties of nanostructured materials. In this Account, we review the advances that have been made in facilitating the recording of the required series of 20 electron microscopic images and the subsequent process of 3D reconstruction of specimens that are vulnerable, to a greater or lesser degree, to electron beam damage. We describe how high-fidelity 3D tomograms may be obtained from relatively few 20 images by incorporating prior structural knowledge into the reconstruction process. In particular, we highlight the vital role of compressed sensing, a recently developed procedure well-known to information theorists that exploits ideas of image compression and "sparsity" (that the Important image information can be captured In a reduced data set). We also touch upon another promising approach, "discrete" tomography, which builds Into the reconstruction process a prior assumption that the object can be described In discrete terms, such as the number of constituent materials and their expected densities. Other advances made recently that we outline, such as the availability of aberration-corrected electron microscopes, electron wavelength monochromators, and sophisticated specime

摘要： As part of a laboratory course, undergraduate students were asked to use baker's yeast cells as biotemplate in preparing TiO2 powders and to test the photocatalytic activity of the resulting materials. This laboratory experience, selected because of the important environmental implications of soft chemistry and photocatalysis, provides an opportunity to teach valuable laboratory skills and to introduce students to the synthesis, isolation, and characterization of inorganic materials. This laboratory activity is adaptable to a range of educational levels and to various instrumental techniques.
