The development of a scanning electron microscope (SEM) suitable for instructional purposes has created a large number of outreach opportunities for the Materials Science and Engineering (MSE) Department at Iowa State University. Several collaborative efforts are presently underway with local schools and the Department of Curriculum and Instruction (C&I) at ISU to bring SEM technology into the classroom in a near live-time, interactive manner. The SEM laboratory is shown in Figure 1.Interactions between the laboratory and the classroom use inexpensive digital cameras and shareware called CU-SeeMe, Figure 2. Developed by Cornell University and available over the internet, CUSeeMe provides inexpensive video conferencing capabilities. The software allows video and audio signals from Quikcam™ cameras to be sent and received between computers. A reflector site has been established in the MSE department that allows eight different computers to be interconnected simultaneously. This arrangement allows us to demonstrate SEM principles in the classroom. An Apple Macintosh has been configured to allow the SEM image to be seen using CU-SeeMe.

Improve Instruction

The Materials Science Department at Iowa State University has developed a laboratory designed to improve instruction in the use of the scanning electron microscope (SEM). The laboratory makes use of a computer network and a series of remote workstations in a classroom setting to provide students with increased hands-on access to the SEM. The laboratory has also been equipped such that distance learning via the internet can be achieved.A view of the laboratory is shown in Figure 1. The laboratory consists of a JEOL 6100 SEM, a Macintosh Quadra computer that acts as a server for the network and controls the energy dispersive spectrometer (EDS), four Macintosh computers that act as remote workstations, and a fifth Macintosh that acts as an internet server. A schematic layout of the classroom is shown in Figure 2. The workstations are connected directly to the SEM to allow joystick and computer control of the microscope. An ethernet connection between the Quadra and the workstations allows students seated there to operate the EDS. Control of the microscope and joystick is passed between the workstations by a switch-box assembly that resides at the microscope console. When the switch-box assembly is activated a direct serial line is established between the specified workstation and the microscope via the SEM’s RS-232.

Materials science is highly significant in space program investigation, energy production and others. Therefore, designing, improving and predicting advanced material properties is a crucial necessity. The high temperature creep and corrosion resistance of Ni-based superalloys makes them important materials for turbine blades in aircraft engines and land-based power plants. The investment casting process of turbine blades is costly and time consuming, which makes process simulations a necessity. These simulations require fundamental models for the microstructure formation. In this paper, we present advanced analytical techniques in describing the microstructures obtained experimentally and analyzed on different sample’s cross-sectional images. The samples have been processed on board the International Space Station using the MSL-EML device based on electromagnetic levitation principles. We applied several aspects of fractal analysis and obtained important results regarding fractals and Hausdorff dimensions related to the surface and structural characteristics of CMSX-10 samples. Using scanning electron microscopy (SEM), Zeiss LEO 1550, we analyzed the microstructure of samples solidified in space and successfully performed the fractal reconstruction of the sample’s morphology. We extended the fractal analysis on the microscopic images based on samples solidified on earth and established new frontiers on the advanced structures prediction.

Rare earth metals (REM) occupy a special and important place in our lives. This became especially noticeable during the rapid development of industry in the industrial era of the twentieth century. The tendency of development of the rare-earth metals market certainly remains in the XXI century. According to experts estimates the industry demand for chemical compounds based on them will tend to grow during the nearest years until it reaches the market balance. At the same time, the practical use of high-purity rare-earth metals requires the most accurate understanding of the physical properties of metals, especially magnetic ones. Despite a certain decline in interest in the study of high-purity REM single crystals during the last decade, a number of scientific groups (Ames Lab, Lomonosov Moscow State University (MSU), Baikov Institute of Metallurgy and Materials Science Russian Academy of Science (RAS)) are still conducting high-purity studies on high-purity metal samples. The present article is a combination of a review work covering the analysis of the main works devoted to the study of heavy REMs from gadolinium to thulium, as well as original results obtained at MSU. The paper considers the electronic properties of metals in terms of calculating the density of states, analyzes the regularities of the magnetic phase diagrams of metals, gives the original dependences of the Neel temperature and tricritical temperatures for Gd, Tb, Dy, Er, Ho, Tm, and also introduces a phenomenological parameter that would serve as an indicator of the phase transformation in heavy REMs.

X-ray scattering is a promising non-invasive technique to study evolving nano- and micromechanics in clays. This study discusses the experimental considerations and a successful method to enable X-ray scattering to study clay samples at two extreme stages of consolidation. It is shown that the proposed sample environment comprising flat capillaries with a hydrophobic coating can be used for a wide range of voids ratios ranging from a clay suspension to consolidated clay samples, that are cut from larger specimens of reconstituted or natural clay. The initial X-ray scattering results using a laboratory instrument indicate that valuable information on, in principal evolving, clay fabric can be measured. Features such as characteristic distance between structural units and particle orientations are obtained for a slurry and a consolidated sample of kaolinite. Combined with other promising measurement techniques from Materials Science the proposed method will help advance the contemporary understanding on the behaviour of dense colloidal systems of clay, as it does not require detrimental sample preparation

The article is devoted to the development problems of the X-ray Photoelectron Spectroscopy (XPS) method in Ukraine. XPS is a modern method for studying the electronic structure of atoms. The XPS method is used at all stages of the synthesis and study of materials, the functional properties of which are determined by the state of the surface or interphase boundaries, charge states of atoms and the type of functional groups, and material degradation processes. The objects of study are catalysts, coatings, chemical sensors, sorbents, coordination and organometallic compounds (chemistry, materials science, phar­maceuticals), surface condition and composition (microelectronics), thin films (optics), alloys (aviation and space industry), nanopowders, nanofilms (nanotechnology). The method is relevant for the implementation of targeted synthesis of materials. In the world, the XPS method is widespread and integrated into innovative branches of science and technology, and XPS - instrumentation - is a high-tech business. In Ukraine, the method is practically not presented, there is no competition in this field of instrumentation. The article proposes the creation on the basis of the National Academy of Sciences of Ukraine a park of unitary, high-quality and affordable domestic XPS-spectrometers and the opening of a service center. The XPS method is necessary for most of the institutes of the National Academy of Sciences of Ukraine from the departments of chemistry, physics and astronomy, physical and technical problems of materials science, earth sciences and all specialized faculties of state universities. In general, for Ukraine, this is at least 50 spectrometers. The mechanism for the implementation of the project can be the formation of a state order for the development and manufacture of a batch of XPS spectrometers on the basis of imported and domestic components (50:50) and attracting business to the project. Creation of a network of Domestic XPS-spectrometers allows to obtain a sharp increase in the efficiency of scientific research in chemistry, physics, materials science and is one of the conditions for Ukraine’s transition to an innovative economy.

Robert Sproull, the director of AREA (Advanced Research Projects Agency) in the Pentagon, recorded that Pennsylvania State University and Carnegie Institute of Technology first made proposals in 1957 for “interdisciplinary block funding” in what would essentially become “materials” research. But it was the industrial push (by W.O. Baker of AT&T Bell Laboratories and C.G. Suits of General Electric) that helped ARPA start the funding of 12 interdisciplinary materials research laboratories (IDMRLs) between 1960 and 1963. Pennsylvania State University was added in 1963 as a special modest grant limited to materials preparation (synthesis and processing). NASA and the Atomic Energy Commission added six more within two years. The first interdisciplinary degree program in “materials” (then called solid-state technology), administered directly by a graduate school committee drawn from 10 departments, was started under my chairmanship, at Penn State in 1959-60. Probably the first departmental degree program in which a metallurgy department expanded its scope (and changed its name) to include other materials was started at nearly the same time at North western University by Prof. M.E. Fine. It is noteworthy that at least in these two cases the intellectual and curricular argument for integration of degree work preceded the research grants and organization. These two separate patterns have both now permeated the entire national system, and we should clearly distinguish between them. By 1969 the first national colloquy on materials, held at Penn State and published under the title Materials Science and Engineering in the U.S., took an evaluative look at materials education.

This conceptual paper underlines the necessity of research into sociotechnical systems in modern high-tech industries. Production of sophisticated products is foreseen to build the competitiveness of the advanced economies’ industrial sectors in the future. Increasingly, competitiveness in such industries depends on a complex interaction between social factors such as knowledge sharing, knowledge generation, learning and innovation, and technical factors such as robotization, automation and information systems. However, up to now, improvements and developments in these industries have tended to be biased towards the technology side. To balance this and to take into account the necessity of more effective human – machine interaction, and the need of knowledge sharing, learning and innovation, it proposes a mode for how to challenge highly automated, high-tech and knowledge based high-cost manufacturing, where: 1) State-of-the-art technology is necessary, but not sufficient; 2) state-of-the-art technology requires high level of competence and advanced organization, and 3) a joint organizational and technical perspective is needed in order to develop sustainable competitiveness through high performance work systems in high-tech manufacturing. Operational excellence in such niches requires companies that, through sophisticated practices of organization and management, are able to exploit systems of advanced manufacturing technology.
