Engineers and materials scientists are constantly working to improve the quality of our built environments and vehicles, including noise levels and vibration. The researchers pursuing the duel goals of safety and comfort are increasingly being challenged as the projects they work on advance technologically, in size and are constructed with new materials. Buildings grow taller and must compensate for greater movement and vibrations from wind or shifting foundations. Cars especially are undergoing drastic changes that require a rethinking of the material and designs of their frames, panels, doors and windows. The advent of electric motors for example, has reduced overall noise but shifted the frequency of sound higher, making them more uncomfortable. Assistant Professor Shuichi Akasaka, who is based in the Department of Materials Science and Engineering at Tokyo Institute of Technology in Japan, is carrying out research to design new materials that reduce vibration and noise, and create the quiet, safe automobiles and living spaces of the future.

AbstractAs crystallography merges with materials science and engineering, mathematical crystallography is growing in new directions, including: Characterizing new materials with unusual properties; Imaging, including but not limited to diffraction; Exploring and exploiting superspaces; Mapping the aperiodic landscape, from chaos to classical periodicity and beyond; Re-modeling the structures of real crystals, both periodic and aperiodic; Modeling self-assembly and self-reorganization on the nanoscale. In short, it’s not (just) about space groups and tilings anymore.

The Australian Nuclear Science and Technology Organisation (ANSTO) has recently started commissioning the new Australian Research Reactor OPAL that has replaced the old HIFAR reactor in January 2007. At the first stage, the new reactor will provide neutrons to several neutron scattering instruments. Among them is the residual stress diffractometer Kowari that was designed to study engineering problems related to residual stresses as well as allow material science research using neutron diffraction. We give an update on the progress of the instrument’s installation and commissioning and present an example to illustrate how neutron diffraction can be used to obtain information about residual stresses in a flash butt welded plate.

In response to the development of new materials and the application of materials and components in new technologies the direct measurement, calculation and evaluation of textures and residual stresses has gained worldwide significance in recent years. Non-destructive analysis for phase specific residual stresses and textures is only possible by means of diffraction methods. In order to cater for the development of these analytical techniques the new Materials Science Diffractometer STRESS-SPEC at FRM-II is designed to be equally applied to texture and residual stress analyses by virtue of its flexible configuration. The system compromises a highly flexible monochromator setup using three different monochromators: Ge (511), bent silicon (400) and pyrolitic graphite (PG). This range of monochromators and the possibility to vary the take-off angles from 2θM = 35º to 110º allows wavelength adjustment such that measurements can be performed around a scattering angle of 2θS ~ 90º. This is important in order to optimise neutron flux and resolution, especially for stress analysis on components, since the gauge volume element in that case is cubic and large vertical divergences due to focusing monochromators do not affect the spatial resolution. The instrument is now available for routine operation and here we will present details of recent experiments and instrument performance.

China is now confronted with the tasks of both promoting the economic growth and protecting the environment. Environmental protection has been adopted as the basic national policy to achieve sustainable development. The progress and innovations in the field of material science and engineering are expected to make great contributions since they can help to increase efficiency and reduce pollution. In this paper, the environment situation in China was reviewed to highlight some certain fields that need the efforts from material scientists. And some new technologies were also discussed as the potential methods to deal with these problems. In summary, this paper can be served as a clue for the material researchers who want to contribute to Chinese environmental protection.

ABSTRACTOpportunities in the materials science and engineering field appear quite plentiful into the next century. An increasing number of materials engineers will be needed by industry to develop new materials as well as adapt current ones to new needs. Is there a shortage of metallurgical/materials engineers? Academic institutions with existing or developing programs in materials may affect significant increases in enrollment by “marketing” materials high technology. The Department of Metallurgical Engineering at The University of Texas at El Paso has made exceptional progress in recruiting and retaining prospective engineering students into this technical area. What has been successful at UTEP may also benefit other academic programs.

ABSTRACTA review of the educational literature on naive concepts about principles of chemistry and physics and surveys of science museum visitors reveal that people of all ages have robust alternative notions about the nature of atoms, matter, and bonding that persist despite formal science education experiences. Some confusion arises from the profound differences in the way that scientists and the lay public use terms such as materials, metals, liquids, models, function, matter, and bonding. Many models that eloquently articulate arrangements of atoms and molecules to informed scientists are not widely understood by lay people and may promote naive notions among the public. Shifts from one type of atomic model to another and changes in size scales are particularly confusing to learners. People's abilities to describe and understand the properties of materials are largely based on tangible experiences, and much of what students learn in school does not help them interpret their encounters with materials and phenomena in everyday life. Identification of these challenges will help educators better convey the principles of materials science and engineering to students, and will be particularly beneficial in the design of the Materials MicroWorld traveling museum exhibit.
