A centrifugally atomized rapidly solidified Al-8Fe-2Mo powder was characterized by Light Microscopy (LM), Scanning Electron Microscopy (SEM) and Analytical Electron Microscopy (AEM). The powder sample was studied in an as-solidified state and after annealing in 1 at. argon for 6 hr at 400°C. Further studies have characterized the consolidated bars produced by compaction and extrusion of these powders.The 30 to 150 μm powders are spherical as seen in the SEM (Fig.1) with small (5 to 15 μm) satellite powders sometimes attached in external (A,B Fig.1) and internal (A Fig.2C) locations. A comparison of powders (epoxy mounted and polished) by both the LM (Fig. 2A) and the SEM (Figs. 2B and 2C) reveals a two component microstructure with occasional voids.

Topic: Characterization of Non-Conductive or Charging Materials by Microbeam AnalysisThe goal of this topical conference is to present the state of the art for materials characterization of non-conductive or charging materials using microbeam analysis. Examples of charging materials include polymeric materials, ceramic materials, and photoresist materials in the microelectronic industry. Also, the characterization of biological specimens will be covered because they are prone to problems related to charging. These materials are of great technological importance and their characterization is still a great challenge because they charge when analyzed with an electron beam. The techniques of microbeam analysis that will be considered are: X-ray Microanalysis in the Electron Microprobe, Low Voltage Scanning Electron Microscopy, Environmental Scanning Electron Microscopy, Analytical Electron Microscopy with Field Emission Transmission Electron Microscopy, and Focused Ion Beam Milling for specimen preparation. World experts will present papers on these topics. Papers from this topical conference will be published in a special issue of Microscopy & Microanalysis.

Several populations of four known species of the genus Pungentus (P. clavatus, P. engadinensis, P. marietani and P. silvestris), collected in the wild and in cultivated soils from the Iberian Peninsula, are studied. Detailed redescriptions and morphometrics are presented for each species. Illustrations are provided, including line drawings, light microscopy pictures of the four species as well as scanning electron microscopy observations of P. engadinensis. The Iberian populations are compared to type and other known populations, and new data are given that provide a better characterization of these taxa. Pungentus engadinensis is the most widely distributed species in the Iberian Peninsula.

Clerodendrum splendens A. Chev., Clerodendrum x speciosum Tiej. & Binn, Clerodendrum thomsonae Balf. F., Clerodendrum ugandense L., Congea tomentosa Roxb., Duranta erecta L., Petrea volubilis L. and Petrea volubilis f. albiflora (Standl.) Standl. pollen grains were acetolyzed, photographed and measured under light microscopy and scanning electron microscopy. Values presented are averages in micrometers. Grains are monads, radially symmetrical, isopolar, large (C. ugandense, very large, C. tomentosa, small-medium and D. erecta, medium),tricolpate (P. volubilis f. albiflora, dimorphic grains with 3-4 colpus). Ambitus is circular (C. tomentosa and D. erecta, sub-circular, P. volubilis , triangular, P. volubilis f. albiflora, triangular-quadrangular). The form is oblate-spheroidal (C. splendens, C. x speciosum, C. ugandense), prolate-spheroidal (C. thomsonae), prolate (C. tomentosa), suboblate (D. erecta) and oblate (P. volubilis, P. volubilis f. albiflora). Exine thickness is in C. splendens 4,28, C. x speciosum 4,19, C. ugandense 4,33, C. thomsonae 4,18, C. tomentosa 1,4, D. erecta 1,55, P. volubilis 2,49, P. volubilis f. albiflora 2,68. Ornamentation is micro-echinate (C. splendens, C. x speciosum, C. thomsonae), echinate (C. ugandense), reticulate (C. tomentosa), psilate (D. erecta, P. volubilis, P. volubulis f. albiflora). Duranta and Petrea are close to Verbenaceae pattern, Congea to Lamiaceae and Clerodendrum loosely to Lamiaceae.
