( Hoseini et al . 2014 ; Gorgani-Firouzjaee et al . 2015 ). The morphology of P. clausa has been studied by Ortlepp (1922) , Li (1934) and Gorgani et al . (2013) . However, some morphological aspects of the cephalic structures and the morphometric data of this species remain insufficiently known. Here the detailed morphological characters of P. clausa based on the newly collected material from the Amur hedgehog E. amurensis Schrenk in China were studied using light and scanning electron microscopy (SEM). Materials and Methods Parasites collected from E

(1) elucidate species diversity within the genus Aureobasidium isolated from various wood samples, (2) describe their culture features, and (3) to detect the soft-rot patterns of Aureobasidium species isolated in this study by means of scanning electron microscopy (SEM). Materials and methods Sampling and culture characteristics: Fungal strains were isolated from Japanese red pine ( Pinus densiflora ), Korean pine ( P. koraiensis ), radiata pine ( P. radiata ), and chromate copper arsenate (CCA)-treated wood ( P. koraiensis and P. radiata ) ( Table 1

of HWE wood (HWEW) and the corresponding impacts to performance properties. To fill this gap, the present study addresses the ultrastructure of cell walls and distribution of xylans (Xs) and glucomannans (GMs) in unextracted and HWEW by means of immunolocalization and labeling methods paired with transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Previous studies focusing on immunolocalization and labeling methods proved their efficiency for studying the distribution of wood cell wall components in various tissues (Awano et al. 1998

. The decrease in wet zero-span values was most likely caused by preferential action of CBH on structurally irregular zones in the fiber wall coupled with greater sensitivity of wet zero-span testing towards the localized fiber defects. The fracture zone of the wet zero-span tested samples was imaged by scanning electron microscopy (SEM). Visual obser- vation revealed differences in fiber fracture between treated and control samples. The straighter and cleaner fractures of the treated sample could be attributed to the localized hydrolytic action of CBH. Visual

Foreign Body Contamination of Food – Scanning Electron Microscopy and Energy Dispersive Spectroscopy as Tools for Identification Bryony James Abstract Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) are powerful tools for the characterisation of foreign body (FB) or particulate contamination of food products. Whether the result of processing, packaging or interaction with consumers, once identified foreign body contamination needs to be characterised as rapidly and efficiently as possible in order

(DiATOME histo, 4.0 mm, 45°, Diatome AG, Biel, Switzerland). The semi-thin sections (1 μm) were transferred to quartz microscopic slides (Plano GmbH, Wetzlar, Germany) and thermally fixed. The sections were immersed in a drop of non-UV-absorbing glycerine (glycerine/water mixture n D =1.46) and covered with a quartz cover slip. As reference, unmodified radiata pine sapwood specimens were also prepared, following the same embedding process. In addition, small cubes (1 cm 3 ) of W untr and W FA were prepared for light microscopy (LM) and scanning electron microscopy (SEM

Transmission Research Institute (STRI) hydrophobicity classification and scanning electron microscopy (SEM) are prominent techniques [34–37]. Fourier transform infrared (FTIR) spectroscopy is a widely used tool to investigate structural changes in the material at the molecular level [38, 39]. Previously, the EPDM has been evaluated by many authors for its weathering resistance [6, 21, 40–42]. However, under accelerated 5000 h aging EPDM/SiO 2 nano, micro and hybrid composites with reference to neat EPDM (NE) have not been studied before. Furthermore, in other studies EPDM

Abstract

The interest about zinc oxide is increasing thanks to its unique chemical and physical properties. Our attention has focused on preparation powder of 1D nanostructures of ZnO nanowires with precisely defined morphology include characterization size (length and diameter) and shape controlled in the scanning electron microscopy (SEM). We have compared results of SEM with dynamic light scattering (DLS) technique. We have found out that SEM method gives more accurate results. We have proposed transformation process from ZnO nanowires on substrates to ZnO nanowires powder by ultrasound peeling to colloid followed by lyophilization. This method of the mass production of the ZnO nanowires powder has some advantages: simplicity, cost effective, large-scale and environment friendly.
