โœฆ Synopsis

There are many occasions when chemists need to know detailed information pertaining to the shapes and morphology of minute (nanometer-sized) objects and the topography of nanopores. In characterizing various kinds of electronic devices ranging from quantum dots to quantum wells, in determining the structure of viruses, in visualizing the architecture of supramolecular assemblies inside eukaryotic and prokaryotic cells, and especially in the identification of nanoparticle catalysts supported on high-area nanoporous solids, it is important to know-without recourse to sectioning or other destructive techniques-the precise location, spatial

High-resolution dark-field electron microscopy was used to observe the domain structure in IRB-2 carbon black. The domains are equiaxed with a dia. of 16 f0.5 A. Most of them have their layerplanes tangent to the surface of the surface of the particle, but occasional domains are observed that are no

High-field, high-resolution 13C cross-polarization and magic angle spinning nuclear magnetic resonance experiments are reported on Yallourn brown coal and on products obtained from the coal by heat treatment. The spectral resolution at 75 MHz is much improved over that previously reported for lower
