The purpose of this work is to study the effect of kaolin particle size for the preparation of low cost ceramic membrane suspension and ceramic membrane structure. Kaolin particle size is categorized into two categories; i) ≤ 1µm and ii) ≥ 1 µm. The suspension is prepared via stirring technique under 1000 rpm at 60°C. The particle size of kaolin is characterized using field emission scanning electron microscope (FESEM) and the prepared suspension is characterized in term of its viscosity. Results indicate that the particle size gave significant effect to the viscosity of ceramic membrane suspension. Preliminary data showed that kaolin with particle size ≤ 1µm resulted ceramic membrane with dense structure.

Abstract. The preparation of microfossil specimens for study with the scanning electron microscope involves the transfer of material from slides to stubs. Specimens must then be oriented and mounted securely. To do this accurately the slide and stub should both be viewed through a stereomicroscope. However due to differences in shape and height, both surfaces are not usually in the plane of focus at the same time. Many micropalaeontologists routinely use small boxes or sample tube lids to hold the stub and refocus before finally mounting the specimens. The risk of dropping specimens is reduced by using a single carrier, securely holding both the slide and stub. The design illustrated below (fig.1) was developed from a prototype constructed from cardboard and plastic. The metal unit can easily be made in a workshop at a very low cost or cardboard versions made in the laboratory.The stage is based on the principle that both slide and stub should be held securely, close together and in the same plane of focus. The slide holders should be secure but not too tight otherwise the stub may be jarred as slides are changed. The number of slides which can be held on one unit may be varied. The presence of two holders has proved useful, any more could make the unit cumbersome. If the microscope to be used does not have a wide stage then it may prove more practical to have only one holder.The stub holders allow the stub to be clamped to . . .

In order to improve the oxidation resistance of the ZrCoCe getter, highly porous Ni/ZrCoCe stack getter films were grown by the magnetron sputtering method. Scanning electron microscope (SEM) analysis indicate that the Ni/ZrCoCe stack film is composed of isolated columns. The film surface with cauliflower-like topography is formed among finely packed nanocrystals. Gas sorption investigation shows that the Ni/ZrCoCe stack film can be activated at 300 °C for 30 min and exhibits more favorable sorption capability than ZrCoCe bi-layered film. XPS results show that the Ni protective layer can play an important role in protecting the ZrCoCe film against oxidation. It can also improve the surface dissociation and diffusion of H2.

A silicon microfabrication technique has been applied toward the development of a Miniature Scanning Electron Microscope (MSEM). The fabrication technology is not only precise but is inexpensive compared to conventional methods of electron microscope construction and is easily extended to the construction of arrays of MSEMs for applications in high throughput e-beam lithography and wafer inspection.An electrostatic electron lens consists of a series of planar electrodes with central apertures that are precisely aligned to and electrically isolated from one another. This structure is fabricated using silicon as the electrode material and Pyrex optical fibers as the insulators. The electrodes are fabricated on four inch (100) orientation silicon wafers that are patterned on both sides and anisotropically etched to form four orthogonal v-grooves and an open diaphragm with a circular aperture in the center. The apertures are formed by reactive ion etching. The wafers are then diced to create approximately 100 7 mm by 9 mm electrodes.

This study briefly reports a newly developed nanopatterning technology utilizing a so-called micro droplet jetting system, which can be used in various applications such as nanofabrication. Compared with the conventional methods, this technology has the advantages as follows: it can be manipulated easily and patterned freely as the user requires; furthermore, it shows high-reliability and high-stability with very low cost. The typical specs of the micro droplet jetting system for fabricating nanodevice show as follows: (1) nanoparticle size: 50–60 nm; (2) characteristic wavelength: 400–450 nm; (3) volume of droplet: 6 ppl; (4) size of pixel: 70 μm. In this article, the nanopatterning technology adopting the micro droplet jetting system has been demonstrated to be useful for nanopatterning the pixels which consist of nanoparticles, organic luminescent materials. In addition, the micro topography and the luminescent property of the patterned surface have been characterized by using Scanning Electron Microscope (SEM) and fluorescence microscope, respectively. Finally, the fluorescence of the patterned nanoparticles was observed.

Anatase and rutile TiO2 nanostructure have been successfully synthesized via CD reactive magnetron sputtering and hydrothermal synthesis followed by post-treatment from titanium powder. The morphology and crystalline structure of the nanostructure are characterized in detail with X-ray diffraction (XRD), Field Emissiom Scanning Electron Microscope (FE-SEM), Scanning Electron Microscope (SEM), energy dispersive X- ray and energy dispersive x-ray analyzer (EDX). The pattern showed anatase and rutile phase crystalline structure. The thin films showed the surface as viewed uniform tiny spots distribution. TiO2 nanostructures were successfully synthesized using a simple hydrothermal synthesis method from TiO2 nanSubscript textoparticles. The samples were synthesized by means of the hydrothermal reaction of TiO2 nanoparticle of anatase and rutile phase. In a typical procedure, The time were varied, and cooled to room temperature, naturally. The samples showed structures of crystalline, anatase and rutile phases. They were morphology TiO2 nanorods, TiO2 nanowires and TiO2 nano shape with the diameters of about 30-300 nm. The EDX analysis of an area containing a large amount of TiO2 nanostructure reveals the existence of Na, Ti and O elements.

Recently, Co(OH)2 has gained much attention as a promising electrocatalyst. Herein, we synthesized Co(OH)2-decorated TiO2 film for electrocatalytic water splitting by a facile and low-cost electrochemistry method, which possessed enhanced performance for oxygen evolution reaction. The results of X-ray diffractometry, transmission electron microscope, scanning electron microscope and X-ray photoelectron spectroscopy verify the successful decoration of Co(OH)2 electrocatalysts onto the surface of TiO2. Moreover, photoelectrocatalytic measurements illustrate that the Co(OH)2-decorated TiO2 shows higher current density than pure TiO2 sample. The results obtained in this work give deep insights into the development of photoelectrochemical water splitting.

Most manufacturers of scanning electron microscopes (SEM) now offer models that display an image digitally. This holds many advantages, including the ability to store the image on a disk and perform image analysis on the sample. Most SEMs in service, however, produce only an analog video output; they do not have the ability to digitize the image. Film is the only method of storing images.Consequentially, film is a significant portion of every microscopy laboratory’s budget. Completely eliminating the use of film from use is not practical. There will always be the need to examine a hard copy of the image; many programs require duplicate copies of each image generated; and it is sound practice to keep a copy of each image on file. By archiving digital images to an inexpensive media, the amount of film used or the time devoted to processing negatives can be greatly reduced.By using personal computers (PCs)s, with a digitizing board and analog to digital (A/D) board, it is possible to construct a relatively low cost digitizing system for any SEM.

Abstract Microstructural diagnostic for electronic packaging development and failure analysis under industrial manufacturing conditions require fast but reliable preparation routines. The aim of the presented poster is to introduce a time and cost efficient preparation technique for FESEM (field emission scanning electron microscope) investigations with focus on typical issues in electronic packaging development and failure analysis. The new ion beam based technique acts as a low cost alternative to FIB, able to prepare much wider section areas, combined in a tool, which can also be used for standard ion beam polishing processes.
