In this paper, composition analysis using scanning electron microscopy/energy-dispersive X-ray spectroscopy analysis (SEM-EDX) and laser-induced breakdown spectroscopy (LIBS) for particulate matter in diesel exhaust is presented. Conventionally, scanning mobility particle sizer (SMPS) has been widely used to obtain particle size distribution of the suspended particles. However, real-time analysis of the composition of diesel particulate matter is difficult because of the small sized particles

Semiconductive nanometer-size material ZnCo2O4 was synthesized by a solution combustion reaction of inorganic reagents of Zn(NO3)3. 6H2O, Co(NO3)3.6H2O and glycine as a fuel. The process was a convenient, environment friendly, inexpensive and efficient preparation method for the ZnCo2O4 nanomaterial. The synthesized materials were characterized by TG/DTA, XRD, EDX, SEM, and TEM. Conductance responses of the nanocrystalline ZnCo2O4 thick film were measured by exposing the film to reducing gases

An Egyptian, plant pathogenic Fusarium solani isolate was grown on cobalt concentrations of 0, 50, 200, 500, 800, and 1000 ppm. The isolate survived concentrations up to 800 ppm, however failed to grow at 1000 ppm. Morphology and elemental analysis of the isolate under the investigated Co concentrations were studied using Scanning electron microscopy (SEM) and energy dispersive X-ray microanalysis (EDX). The isolate reserved its morphology up to a concentration of 200 ppm. Morphological

Malenchus (Malenchus) (Andrássy, 1968) and Malenchus (Telomalenchus) (Geraert, 2008; Qing and Bert, 2017; Siddiqi, 2000). There are currently available molecular data for representatives of Filenchus and Malenchus (e.g. Atighi et al., 2013; Qing et al., 2017). The genus Discotylenchus was originally established based upon traditional criteria, and SEM and molecular data of the type populations of its six known species sensu Geraert (2008) are not available. The only available SEM images of the genus

Pingelly with typical P. curvicauda features were fixed in 4% formaldehyde solution and sent to an expert taxonomist in the UK for further characterization. The detailed morphometric measurements obtained were compared with those taken in Australia.
Preparation of nematode samples for scanning electron microscopy
Scanning electron microscopy (SEM) was used to further characterize P. curvicauda. To do this, single nematodes were fixed in 3% glutaraldehyde in 0.025 M phosphate buffer (pH 7.0) overnight
