A Hitachi S-2300 scanning electron microscope was used to examine the morphology of the etched hollow glass microspheres. The results of these investigation are discussed in the next section.. Sodium borosilicate hollow glass microspheres are strong, low density additives used in a variety of industrial applications. The as-received sodium borosilicate HGM has a size distribution range as shown in the scanning electron micrograph, Fig.

Microstructure and textural properties of Kareish cheese manufactured by various ways

tailieu.vn

In particular, the use of scanning electron microscopy has become the method of choice in many investigations (Madadlou et al . Khosroshahi et al., 2006) and it has proved to be an efficacious method to identify cheese components when fat, protein, and moisture are the major con- stituents (Rahimi et al., 2007). Very limited data exist in the literature regarding the use of elec- tron microscopy (scanning or transmission) to evaluate the microstructure of Kareish cheese..

Kính hiển vi điện tử quét Kính hiển vi điện tử quét (tiếng Anh: Scanning Electron Microscope, thường viết tắt là SEM), là một loại kính hiển vi điện tử có thể tạo ra ảnh với độ phân giải cao của bề mặt mẫu vật bằng cách sử dụng một chum điện tử (chùm các electron) hẹp quét trên bề mặt mẫu. Việc tạo ảnh của mẫu vật được thực hiện thông qua việc ghi nhận và phân tích các bức xạ phát ra từ tương tác của chùm điện tử với bề mặt mẫu vật.

The electron take-off angle was adjusted around 60 0 C with respect to the film surface. Surface morphology of the grafted films was observed by a scanning electron microscope (SEM), model JEOL JSM-5200. The observation was performed to determine the quality of polymer depositions, and especially to check whether micropores appear on the grafted surface..

Relationship between thermal conductivity and foam content. 3.5 Scanning electron microscopy observation Figure 8 shows the SEM images of all foam concrete with magnification of 500 times. The air bubbles inside concrete is contributable to the reduction in density, compressiv e strength, ultrasonic pulse v elocity, and thermal conductivity, but increases water absorption of foam concrete.

Aerosol-assisted chemical vapor deposition of copper sulfide nanostructured thin film from newly synthesized single-source precursor

tailieu.vn

Scanning electron and atomic force microscopic studies of the nanostructured thin film The scanning electron microscopy (SEM) image of the film (Figure 3a) showed the film morphology with evenly distributed small crystallites without any preferred orientation and diffusion grain boundaries. Energy-dispersive X- ray spectroscopy (EDX) analysis of the film shows that the Cu:S ratio is 72.5:27.5.

Abstract: Nutlets of 13 taxa of subfamily Cyperoideae (Cyperaceae) from Egypt were investigated using light and scanning electron microscopes to ascertain the taxonomic utility of the nutlet in corroborating and elaborating on distinctions between closely related genera and species. Seven different types of anticlinal cell wall boundaries were described, four types of outer periclinal cell walls, and five different forms of the secondary cell walls were recognized.
