Potential Applications

The cobalt disilicide/silicon system has potential applications as a metal-base and as a permeable-base transistor. Although thin, low defect density, films of CoSi2 on Si(111) have been successfully grown, there are reasons to believe that Si(100)/CoSi2 may be better suited to the transmission of electrons at the silicon/silicide interface than Si(111)/CoSi2. A TEM study of the formation of CoSi2 on Si(100) is therefore being conducted. We have previously reported TEM observations on Si(111)/CoSi2 grown both in situ, in an ultra high vacuum (UHV) TEM and ex situ, in a conventional Molecular Beam Epitaxy system.The procedures used for the MBE growth have been described elsewhere. In situ experiments were performed in a JEOL 200CX electron microscope, extensively modified to give a vacuum of better than 10-9 T in the specimen region and the capacity to do in situ sample heating and deposition. Cobalt was deposited onto clean Si(100) samples by thermal evaporation from cobalt-coated Ta filaments.

Potential Applications

Ultraviolet laser-irradiation can be used to induce an insulator-to-conductor phase transition on the surface of Kapton polyimide. Such structures have potential applications as resistors or conductors for VLSI applications as well as general utility electrodes. Although the percolative nature of the phase transformation has been well-established, there has been little definitive work on the mechanism or extent of transformation. In particular, there has been considerable debate about whether or not the transition is primarily photothermal in nature, as we propose, or photochemical. In this study, cross-sectional optical microscopy and transmission electron microscopy are utilized to characterize the nature of microstructural changes associated with the laser-induced pyrolysis of polyimide.Laser-modified polyimide samples initially 12 μm thick were prepared in cross-section by standard ultramicrotomy. Resulting contraction in parallel to the film surface has led to distortions in apparent magnification. The scale bars shown are calibrated for the direction normal to the film surface only.

The fabrication of multilayer films (MLF) with layer thicknesses down to one monolayer has led to the development of materials with unique properties not found in bulk materials. The properties of interest depend critically on the structure and composition of the films, with the interfacial regions between the layers being of particular importance. There are a number of magnetic MLF systems based on Co, several of which have potential applications as perpendicular magnetic (e.g Co/Cr) or magneto-optic (e.g. Co/Pt) recording media. Of particular concern are the effects of parameters such as crystallographic texture and interface roughness, which are determined by the fabrication conditions, on magnetic properties and structure.In this study we have fabricated Co-based MLF by UHV thermal evaporation in the prechamber of an atom probe field-ion microscope (AP). The multilayers were deposited simultaneously onto cobalt field-ion specimens (for AP and position-sensitive atom probe (POSAP) microanalysis without exposure to atmosphere) and onto the flat (001) surface of oxidised silicon wafers (for subsequent study in cross-section using high-resolution electron microscopy (HREM) in a JEOL 4000EX. Deposi-tion was from W filaments loaded with material in the form of wire (Co, Fe, Ni, Pt and Au) or flakes (Cr). The base pressure in the chamber was around 8×10−8 torr during deposition with a typical deposition rate of 0.05 - 0.2nm/s.

Synthetic Microbial Communities

Microbial communities drive diverse processes that impact nearly everything on this planet, from global biogeochemical cycles to human health. Harnessing the power of these microorganisms could provide solutions to many of the challenges that face society. However, naturally occurring microbial communities are not optimized for anthropogenic use. An emerging area of research is focusing on engineering synthetic microbial communities to carry out predefined functions. Microbial community engineers are applying design principles like top-down and bottom-up approaches to create synthetic microbial communities having a myriad of real-life applications in health care, disease prevention, and environmental remediation. Multiple genetic engineering tools and delivery approaches can be used to ‘knock-in' new gene functions into microbial communities. A systematic study of the microbial interactions, community assembling principles, and engineering tools are necessary for us to understand the microbial community and to better utilize them. Continued analysis and effort are required to further the current and potential applications of synthetic microbial communities.

Purpose Early identification is a key element for accessing appropriate services for preschool children with language impairment. However, there is a high risk of misidentifying typically developing dual language learners as having language impairment if inappropriate tools designed for monolingual children are used. In this study of children with bilingual exposure, we explored performance on brief dynamic assessment (DA) language tasks using graduated prompting because this approach has potential applications for screening. We asked if children's performance on DA language tasks earlier in the year was related to their performance on a year-end language achievement measure. Method Twenty 4-year-old children from Spanish-speaking homes attending Head Start preschools in the southwestern United States completed three DA graduated prompting language tasks 3–6 months prior to the Head Start preschools' year-end achievement testing. The DA tasks, Novel Adjective Learning, Similarities in Function, and Prediction, were administered in Spanish, but correct responses in English or Spanish were accepted. The year-end achievement measure, the Learning Accomplishment Profile–Third Edition (LAP3), was administered by the children's Head Start teachers, who also credited correct responses in either language. Results Children's performance on two of the three DA language tasks was significantly and positively related to year-end LAP3 language scores, and there was a moderate and significant relationship for one of the DA tasks, even when controlling for age and initial LAP3 scores. Conclusions Although the relationship of performance on DA with year-end performance varies across tasks, the findings indicate potential for using a graduated prompting approach to language screening with young dual language learners. Further research is needed to select the best tasks for administration in a graduated prompting framework and determine accuracy of identification of language impairment.

Abstract The use of podcasting is incredibly widespread, with experts estimating that 60 million Americans will be using podcasting in some form by 2010. The use of podcasting has grown beyond entertainment to become an educational tool, showing promise as a way to disseminate information and create networks of professional learners. However, despite the growing clinical and educational uses of podcasting in other professional disciplines, podcasting is being used primarily as a continuing education tool for speech-language pathologists and audiologists at this time. This article provides guidelines and examines the potential applications for use of podcasting in teaching and learning in communication sciences and disorders.

Ambulatory assessment of emotional states as well as psychophysiological, cognitive and behavioral reactions constitutes an approach, which is increasingly being used in psychological research. Due to new developments in the field of information and communication technologies and an improved application of mobile physiological sensors, various new systems have been introduced. Methods of experience sampling allow to assess dynamic changes of subjective evaluations in real time and new sensor technologies permit a measurement of physiological responses. In addition, new technologies facilitate the interactive assessment of subjective, physiological, and behavioral data in real-time. Here, we describe these recent developments from the perspective of engineering science and discuss potential applications in the field of neuropsychology.
