AbstractAll National Science Foundation funded MRSEC centers have education, outreach and community service as one of their major objectives. The Princeton Center for Complex Materials (PCCM) takes this commitment very seriously. PCCM runs a full slate of education activities including a host of Pre-college science and engineering programs and a research experience for undergraduates and teachers program each summer. Our outreach programs are designed to increase awareness, appreciation and knowledge of materials science.Liberty Science Center (LSC) in Jersey City, New Jersey and the Strange Matter traveling exhibit allowed PCCM to expand its outreach program to include tens of thousands of family audience members. LSC gets 1000's of visitors each weekend, and has expertise in communicating with this audience. Princeton University scientists have expertise in materials science. This partnership required coordination between the LSC staff and the PCCM outreach director in facilitating the training and presentations by faculty and other scientists from Princeton. Together we developed a program that sent over 30 scientists from Princeton University to the liberty science center to offer their enthusiasm for material science to the public. Scientists can reach a much larger audience at a science center than at their home institutions. This can be repeated anywhere in the country where there are science centers is and university research centers willing to work together.

AbstractThe University of Puerto Rico-Mayaguez and University of Wisconsin-Madison Partnership for Research and Education in Materials (UPRM-UW PREM) aims to create richer educational and research opportunities for Hispanic students in Materials Science and Engineering (MSE) and increase their representation in the Materials Science community. The educational and outreach (E&O) components for the UPRM-UW PREM include interventions for high school students and teachers, and undergraduate and graduate students at UPRM. The present report focuses on activities conducted with high school and university students during the third year of the program (2006-07). Results of surveys with student participants indicate that their participation contributes positively to their learning and development in laboratory, research and professional skills, as well as increases student interest in pursuing graduate studies in MSE.

ABSTRACTThe Princeton Center for Complex Materials (PCCM) joined the PBS NOVA/MRS Making Stuff coalition and created a program to inspire middle school students and their teachers about materials science during exciting large programs at Princeton University and multiple pre and post events. As a National Science Foundation funded Materials Research Science and Engineering Center, it is part of PCCM’s mission to inspire and educate school children, teachers and the public about STEM and materials science. Research shows that it is critical to excite students at a young age and maintain that excitement, and without that these, students are two to three times less likely to have any interest in science and engineering and pursue science careers as adults. The Making Stuff TV series offered a great teachable moment in materials science for students and teachers alike. The four episodes, Stronger, Smaller, Smarter and Cleaner aired in January and February, 2011. Our complementary education program helped promote the viewership of the Making Stuff series in the region, and the NOVA episodes helped us by priming the teachers and students to learn more about materials science research conducted at Princeton University. The Making Stuff coalition events we conducted were designed to have the maximum positive impact on students’ attitudes towards science and scientists, in general, and materials scientists and engineers, specifically. Each and every student had an opportunity to interact with dozens of scientists and engineers, in the lab, at table demonstrations and lecture presentations. As an ongoing MRSEC education and outreach program we have developed many successful educational partnerships to increase our impact. Plus, through years of successful education programs and the participation of our materials scientists and engineers, we have cultivated great trust in the schools and local community. The schools eagerly joined as partners in the program to bring their students to the event. Teachers from those partner schools actively participated in associated professional development programs conducted by education staff and PCCM professors before and after the big event. Included were presentations by MRSEC members and the partners from Princeton Institute for the Science and Technology of Materials (PRISM), Princeton University’s chemistry department, DOE funded centers PP-SOC and PPPL, Liberty Science Center, Franklin Institute, our PBS partner NJN and our many school district partners.

The development of a remotely operated scanning electron microscopy (SEM) system and its use by high school students and the public as an outreach program are reported. The SEM and the server are located in the National Institute for Materials Science, Tsukuba, Japan, with client computers installed at a science museum and high schools. Using a secure virtual private network system and scheduling/management groupware, observation of SEM images and energy dispersive X-ray analysis are widely and frequently performed throughout Japan.

The physical foundations for the use of electron energy loss spectroscopy towards analytical purposes, seem now rather well established and have been extensively discussed through recent publications. In this brief review we intend only to mention most recent developments in this field, which became available to our knowledge. We derive also some lines of discussion to define more clearly the limits of this analytical technique in materials science problems.The spectral information carried in both low ( 0<ΔE<100eV ) and high ( >100eV ) energy regions of the loss spectrum, is capable to provide quantitative results. Spectrometers have therefore been designed to work with all kinds of electron microscopes and to cover large energy ranges for the detection of inelastically scattered electrons (for instance the L-edge of molybdenum at 2500eV has been measured by van Zuylen with primary electrons of 80 kV). It is rather easy to fix a post-specimen magnetic optics on a STEM, but Crewe has recently underlined that great care should be devoted to optimize the collecting power and the energy resolution of the whole system.

The object wave o(x,y) = a(x,y)exp(iφ(x,y)) at the exit face of the specimen is described by two real functions, i.e. amplitude a(x,y) and phase φ(x,y). In stead of o(x,y), however, in conventional transmission electron microscopy one records only the real intensity I(x,y) of the image wave b(x,y) loosing the image phase. In addition, referred to the object wave, b(x,y) is heavily distorted by the aberrations of the microscope giving rise to loss of resolution. Dealing with strong objects, a unique interpretation of the micrograph in terms of amplitude and phase of the object is not possible. According to Gabor, holography helps in that it records the image wave completely by both amplitude and phase. Subsequently, by means of a numerical reconstruction procedure, b(x,y) is deconvoluted from aberrations to retrieve o(x,y). Likewise, the Fourier spectrum of the object wave is at hand. Without the restrictions sketched above, the investigation of the object can be performed by different reconstruction procedures on one hologram. The holograms were taken by means of a Philips EM420-FEG with an electron biprism at 100 kV.

The Zeiss 912 is a new fully digital, side-entry, 120 Kv TEM/STEM instrument for materials science, fitted with an omega magnetic imaging energy filter. Pumping is by turbopump and ion pump. The magnetic imaging filter allows energy-filtered images or diffraction patterns to be recorded without scanning using efficient parallel (area) detection. The energy loss intensity distribution may also be displayed on the screen, and recorded by scanning it over the PMT supplied. If a CCD camera is fitted and suitable new software developed, “parallel ELS” recording results. For large fields of view, filtered images can be recorded much more efficiently than by Scanning Reflection Electron Microscopy, and the large background of inelastic scattering removed. We have therefore evaluated the 912 for REM and RHEED applications. Causes of streaking and resonance in RHEED patterns are being studied, and a more quantitative analysis of CBRED patterns may be possible. Dark field band-gap REM imaging of surface states may also be possible.

The dynamical scattering effect, which can be described as the failure of the first Born approximation, is perhaps the most important factor that has prevented the widespread use of electron diffraction intensities for crystallographic structure determination. It would seem to be quite certain that dynamical effects will also interfere with structure analysis based upon electron microscope image data, whenever the dynamical effect seriously perturbs the diffracted wave. While it is normally taken for granted that the dynamical effect must be taken into consideration in materials science applications of electron microscopy, very little attention has been given to this problem in the biological sciences.

A new Zeiss TEM with an imaging Omega filter is a fully digitized, side-entry, 120 kV TEM/STEM instrument for materials science. The machine possesses an Omega magnetic imaging energy filter (see Fig. 1) placed between the third and fourth projector lens. Lanio designed the filter and a prototype was built at the Fritz-Haber-Institut in Berlin, Germany. The imaging magnetic filter allows energy-filtered images or diffraction patterns to be recorded without scanning using efficient area detection. The energy dispersion at the exit slit (Fig. 1) results in ∼ 1.5 μm/eV which allows imaging with energy windows of ≤ 10 eV. The smallest probe size of the microscope is 1.6 nm and the Koehler illumination system is used for the first time in a TEM. Serial recording of EELS spectra with a resolution < 1 eV is possible. The digital control allows X,Y,Z coordinates and tilt settings to be stored and later recalled.

The concept of interfacial width is often invoked in many materials science phenomena which relate to the structure and properties of internal interfaces. The numerical value of interface width is an important input parameter in diffusion equations, sintering theories as well as in many electronic devices/processes. Most often, however, this value is guessed rather than determined or even estimated. In this paper we present a method of determining the effective structural and electronic- structural width of interphase interfaces using low- and core loss fine structure effects in EELS spectra.The specimens used in the study were directionally solidified eutectics (DSEs) in the system; NiO-ZrO2(CaO), NiO-Y2O3 and MnO-ZrO2(ss). EELS experiments were carried out using a VG HB-501 FE STEM and a Hitachi HF-2000 FE TEM.
