    While my group in the last 14 years worked mostly on lead-free piezoceramics, this topic has matured considerably and we now mostly work with industry to transfer knowledge into application. Our new topic with currently four researchers and four openings centers on dislocation-based functionality: Dislocations in oxides are typically heavily charged and embedded in a shell of compensating space charges. Therefore they provide a linear or two-dimensional array of charges stable up to high temperature without any chemical dopant. In the literature dislocations have been demonstrated to enhance oxygen conductivity and to improve the figure of merit of thermoelectrics by reducing thermal conductivity through phonon scattering by dislocations. Dislocations have been suggested to improve interfacial reaction kinetics and have been theoretically predicted to pin domain walls in ferroelectrics. In Darmstadt we have so far focused on establishing a set of techniques to introduce a high density of bulk dislocations into single crystals at room temperature or enhanced temperature and to study (dislocation) creep in polycrystalline oxides. Structural investigations have been performed by dark-field X-ray diffraction, rocking curve analysis, TEM , PFM, NMR and etching techniques. The first property evaluations have been done with respect to electrical and thermal conductivity and domain wall pinning. Select examples will be provided on dislocation structures, electrical and thermal conductivity. We have been working on SrTiO3, BaTiO3, KNbO3, TiO2 and ZrO2.

    This seminar will be followed by tea, coffee, and biscuits at 4pm in the tearoom.

    Dr. Cecilia Mattevi, Department of Materials, Imperial College London.

    Miniaturization over three-dimensions is very attractive for future on-chip technologies where device efficiencies need to be optimized over small areas. This is a new challenge, as device miniaturization has been focused to achieve planar-geometries primarily. Direct-ink-writing (or robocasting), is an additive manufacturing technique that brings the possibility of fabricating architectures with programmable design in the three-dimensions (3D) at different length scales. In this seminar, I will talk about our work on 3D printed electrodes for microsupercapacitors from water-based 2D atomically thin material inks and our synthesis approaches to the 2D layers. The materials of choice are transition metal dichalcogenides (TMDs), which are attracting a considerable interest owing to their multiple functionalities. The inks are composed by highly concentrated atomically thin sheets of TMDs, either exfoliated from bulk powders or obtained via direct synthesis in solution. By tailoring the rheology of our formulated inks, printability has been achieved along with mechanical robustness of the printed structures. The printed architectures, from woodpile to interdigitated electrodes, are extended over a few mm in the three-dimensions and present struts widths as small as 100 μm. The microsupercapacitors show leading areal capacitance and energy density as compared to planar microsupercapacitors, and stability in different electrolytes

    This seminar will be followed by tea, coffee, and biscuits at 4pm in the tearoom.

  • 01Nov

    The Department of Materials Science & Metallurgy will be participating in the University's Postgraduate Open Day on Friday 1 November.  During the afternoon session at the Department there will be opportunities to discuss PhD projects, the MASt in Materials Science, and MPhil in Micro- and Nanotechnology Enterprise.  Guided tours of the labs, and course directors will be available to meet students.  There will be a chartered coach for Open Day vistors wishing to go to the West Cambridge Site which will depart from Queen's Road, Cambridge, between 1 and 1:15pm.  Visitors will receive further information about this coach service when they register for the Open Day.    There is also a regular bus service from the centre of Cambridge to the West Cambridge Site if you are traveling at other times.

    Further details for the Postgraduate Open Day and to register for the event see: https://www.graduate.study.cam.ac.uk/events

     

  • 23Oct

    Tuhin Maity (25 minute talks + 5 minutes of questions). All welcome.

  • 18Oct

    Prof. Tuomas Knowles, Department of Chemistry, Cambridge.

    This talk describes our efforts at elucidating the physical principles that control the self-assembly of protein molecules into fibrillar structures. Such assemblies are involved in biological function and malfunction, and are commonly held together with extended beta sheets when they are known as amyloid fibrils. These species were first discovered in the context of protein aggregation diseases. It has recently become apparent, however, that they also possess a multitude of functional roles in nature. Inspired by these natural roles of protein fibrillar materials, we have also focused our efforts into tailoring the self assembly of peptide and proteins to generate artificial functional materials.

    This seminar will be followed by tea, coffee, and biscuits at 4pm in the tearoom.
