The hexagonal closed packed crystal structures of the higher fullerenes, C76, C78, and C84, have been determined at room temperature in the [001] projection from single crystal electron diffraction intensity data. In all cases, the molecules in the c

Maximum Entropy (ME) techniques have found widespread applicability in the reconstruction of incomplete or noisy data. These techniques have been applied in many areas of data analysis including imaging, spectroscopy, and scattering [Gull and Skillin

One percent Rh/V2O5 catalysts prepared by wet impregnation with RhCl3 · xH2O and subsequent reduction in hydrogen were shown to be subject to the formation of lower oxides of vanadium via an Rh-catalysed reduction process. V4O9, VO2, and V2O3 compou

We consider the situation where an electron diffraction pattern has been obtained from a crystal; from the same sample an image is also produced which, when Fourier-transformed, yields phases for some, but not all, of the diffraction intensities. In
