    CANCELLED - unfortunately Dr Mattevi is unable to deliver her talk today.

    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.

    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.

    The Cambridge Philosophical Society is holding the first lecture of the Michalmas Term, the Larmor Lecture. The Speaker is Professor Serena Best, Department of Materials Science & Metallurgy, whose lecture is entitled "Design of Tissue Engineering Scaffolds - Still Learning our ABC?".

    The lecture is free (no booking required) and open to all who are interested. Entrance to the Bristol-Myers Squibb Lecture Theatre, Department of Chemistry, is adjacent to the Scott Polar Research Institute on Lensfield Road, Cambridge.

    Abstract as follows:

    For many years, there has been interest in the use of biomaterials to replace human tissues damaged by injury or disease. Over time, the materials of choice have gradually changed from those that simply offer mechanical support to those that interact directly with the biological environment. Focus is now on the recruitment and delivery of biological cells to assist in the repair process. With this move from tissue replacement to cell-mediated tissue reconstruction and regeneration (or tissue engineering), there is increasing need for the design of optimised, porous biomaterial structures – often referred to as “Scaffolds”. By first understanding the nature of the tissues that we want to regenerate, it is possible to address the requirements for particular clinical applications.

    This talk will consider two scaffold materials: collagen, a highly versatile and bioactive natural macromolecule; and hydroxyapatite, a calcium phosphate material similar in composition to bone mineral. To optimise tissue repair processes, it is important to understand the influence on cell behaviour of the structure of the scaffold, and the interconnections between the pores within them. Choice of scaffold surface chemistry also allows us to balance scaffold “activity” and mechanical performance. There is also a need to consider an appropriate testing environment to mimic the cellular interactions which take place within the body.

    This talk will cover the recent work undertaken to study the structure and properties of scaffolds for a range of clinical applications in soft and hard tissue repair.

    Amorphous and substoichiometric silicon nitride (SiNx) has been demonstrated to exhibit convertible alloy anode behaviour in Li-ion batteries, i.e., that it irreversibly converts into a mixture of active silicon and an inactive matrix during the initial lithiation of the material. In the subsequent cycles the active silicon component is reversibly lithiated and delithiated, contributing significant reversible capacity, while the inactive matrix component mitigates the severe degradation silicon usually undergoes during such treatment. The result is a material that can maintain a high capacity over a large number of charge and discharge cycles. The properties of the material have been found to be strongly dependent on its nitrogen content; however, the mechanisms that govern this dependency, in particular the specifics of the conversion reaction, have yet to be conclusively determined. Gaining this understanding would allow targeted tuning of the material properties to fit different sets of requirements and applications. Some has been deduced from electrochemical analyses, but further characterization is needed to better elucidate the process. This is the basis for the SAIL project, where we will employ advanced characterization methods, like TEM and synchrotron-based techniques, both in and ex-situ, to further our understanding of this promising material.
