Fruit and seed macro- and micromorphologies of the genus Matthiola (Brassicaceae) in Turkey and their taxonomic value

tailieu.vn

The use of the scanning electron microscope (SEM) technique in these investigations is also extremely effective and important.. There is little knowledge about the fruit and seed macromorphology of Matthiola taxa in the flora of Turkey. Moreover, the fruit and seed micromorphology of Matthiola taxa are also unknown in the flora of Turkey. Therefore, further research is needed to investigate the macro- and micromorphologies of the fruit and seed..

The measurements and scanning electron microscope (SEM) examinations of the grains are presented in Tables 2–4. The pollen morphological descriptions followed the terminology used by Erdtman (1952), Faegri and Iversen (1989), Punt (2007), and Hesse et al. For comparison of the P-E axis, analysis of variance (ANOVA) and Tukey’s test were performed using SPSS 23.00.

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..

Effect of ethanol treatment on morphological and technical properties of corn starch

tailieu.vn

PS1, PS3, PS5, PS7 and PS10 were ethanol/water-soaked corn starch samples with concentrations of respectively.. 2.2.2 Morphology of starch granules observed by scanning electron microscope (SEM). Morphology of the natural and solvent modified starch samples were observed by JSM 7401F scanning electron microscope (SEM) (JEOL, Tokyo, Japan). Corn starch was placed on a specific sample container. The centrifuge tube contained 0.1 g of starch and 1.0 mL of walnut oil.

Environmentally friendly unburnt bricks using raw rice husk and bottom ash as fine aggregates: Physical and mechanical properties

tailieu.vn

The scanning electron microscope (SEM) was used to observe the microstructure of bricks, espe- cially the connection between rice husk and paste. It is interesting that the connection between the back of rice husk and cementitious paste is greatly good as shown in Fig. voids were detected around the connection between the belly of rice husk and paste as shown in Fig.

After determining the characteristics of colonies, we determined the formation of conidiophore, spore chain and surface of spore from the strain 43. an optical microscope at a magnification of 1000 showed that after 48 h of incubation the actinomycetes strain 43 started sporulation.. To determine more accurately the morphology of the strain 43, we observed the morphology of the spore chain and the surface of spore under a scanning electron microscope (SEM).

Metal nanoparticles/carbon nanotube modified electrodes for voltammetric determination of boron

For the further investigation, scanning electron microscope (SEM) images of CNT/GCE, CuNP/CNT/GCE, and AuNP/CNT/GCE were taken. On the other hand, the presence of copper and gold nanoparticles on the CNT/GCE is not clearly observed (not shown here), because the metal ion concentrations were used as dilute concentrations during the electrochemical deposition.. SEM image of CNT/GCE..

A Simple, One-step, Seedless Hydrothermal Growth of ZnO Nanorods on Printed Circuit Board Substrate

tailieu.vn

The morphologies of the ZnO nanorods were investigated by scanning electron microscope (SEM) and X-ray diffraction (XRD). Recently, well-aligned ZnO nanorods have been successfully grown on different kinds of substrates by using a simple, low-temperature, hydrothermal technique [7-8]. The pre-deposition of a ZnO seed layer normally requires high temperature, and extra experimental steps.

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.
