    Prof. Laurence Marks, Northwestern University Department of Materials Science and Engineering.

    It has been known for at least a century that chloride has a major effect on corrosion, often increasing the rate of attack by an order of magnitude or more. This has serious consequences, not just for corrosion in sea water but also within humans; they have similar chloride ion levels. The literature is full of conflicting models each developed with particular approaches focusing on one aspect of the problem, rarely looking at the larger picture. The focus of this talk will be to show that the different conflicting models are not in fact conflicting. Density functional theory calculations show that chloride plays a critical role in disrupting the hydrogen bonding networks at oxide surfaces by replacing chemisorbed hydroxide. This leads to a reduction in the surface free energy which promotes morphological instabilities, these later conclusions being supported by transmission electron microscopy and atom probe tomography results.

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

    Prof. Michele Ceriotti (Laboratory of Computational Science and Modelling, EPFL) 

    Abstract:

    Statistical regression techniques have become very fashionable as a tool to predict the properties of systems at the atomic scale, sidestepping much of the computational cost of first-principles simulations and making it possible to perform simulations that require thorough statistical sampling without compromising on the accuracy of the electronic structure model.

    In this talk I will argue how data-driven modelling can be rooted in a mathematically rigorous and physically-motivated framework, and how this is beneficial to the accuracy and the transferability of the model. I will also highlight how machine learning – despite amounting essentially to data interpolation – can provide important physical insights on the behaviour of complex systems, on the synthesizability and on the structure-property relations of materials.

    I will give examples concerning all sorts of atomistic systems, from semiconductors to molecular crystals, and properties as diverse as drug-protein interactions, dielectric response of aqueous systems and NMR chemical shielding in the solid state.

    The Centre of Advanced Materials for Integrated Energy Systems (CAM-IES) has the pleasure to host a talk by Prof. Dr. Olivier Guillon, Head of Institute, Institute of Energy and Climate Research IEK-1: Materials Synthesis and Processing at Jülich Forschungszentrum. 

    ABSTRACT: The transition to a sustainable and affordable energy supply relies on the introduction of reliable, highly-efficient technologies such as fuel cells, electrolysers, and batteries. The coupling of different energy carriers (electricity and chemicals) is thus made possible over different time scales. At the core of such electrochemical devices, advanced functional ceramics can be tailored to achieve high ionic and/or electronic conductivity. Furthermore, aspects of processability and stability under operation conditions need to be considered. Examples will be given in the field of solid oxide fuel/electrolysis cells and solid-state Li and Na batteries.

    Prof. J. D. Tovar - John Hopkins University

    Several emerging energy technologies require flexible and solution-processable organic-based electronic materials capable of specific degrees of energy transport in order to achieve desired functions.  The range of materials (and applications) is quite diverse, as exemplified by new materials that can facilitate photovoltaic, light emitting or transistor behavior.  The molecular requirements necessary to achieve these functions vary greatly, and this lecture will highlight two fundamental structural considerations relevant to the design of materials that can foster or otherwise regulate efficient energy/charge migration. One aspect involves the use of unusual aromatic building blocks with relatively low degrees of resonance stabilization that can encourage intramolecular electronic delocalization. These types of molecules can display fluxional aromatic properties that support diradical character or can be used to control conjugated polymer backbone energetics. Another aspect involves the control of intermolecular electronic delocalization through the use of water-soluble oligopeptides attached to pi-conjugated oligomers that self-assemble into fibrillar bioelectronic nanostructures containing internal pi-stacked electronic conduits.  This platform enables peptidic energy transport in completely aqueous environments of high ionic strength. In both aspects, the making, breaking and stacking of aromatic rings plays a critical role to define the physical properties of the materials and the possible arenas where they may be employed.

    Speaker: Martin Hytch, Research Director at CEMES-CNRS, Toulouse, France

  • 02Apr

    The 5th meeting of the Cambridge Advances Materials Network, organised by Dr Howard Stone and Dr Nick Jones, will bring together researchers from across Cambridge to discuss the new materials technologies that are needed for the future prosperity of the UK aerospace industry. This industry is now considering radically new airframe designs including; thinner truss-braced wings, laminar flow control, boundary layer ingestion, as well as new aero-engine designs including; open rotors, geared turbofans and, for regional jets, electric propulsion. The realisation of such technologies could lead to significant improvements in fuel efficiency and reduced emissions, thereby offering considerable benefits to the UK and companies working in this sector. However, many of these new, innovative concepts require new materials to be successful and university-based research has the potential; to deliver these key enabling materials.  The meeting will seek to provide a platform for researchers to showcase their work and discuss potential opportunities to collaborate in this industrially important field for UK industry.

  • 20Mar

    Mi-Jin Jin.  (25 min talks + 5 mins of questions). All welcome.

  • 19Mar

    Speaker: Professor James Kirkpatrick 

    Professor Kirkpatrick has a triple doctorate in science and medicine (MD, PhD, DSc) from the Queen's University of Belfast (N. Ireland) and is Emeritus Professor of Pathology at the University Medical Centre in Mainz, Germany. He is a Fellow of the Royal College of Pathologists (FRCPath), London, and has both honorary and visiting professorships in China, Singapore and Sweden.

    His principal research interests are in the fields of biomaterials in regenerative medicine, with special focus on human co-culture systems. During the past years his work has focussed on bone vascularization, as well as co-culture models for respiratory tract regeneration.

    Professor Kirkpatrick is a visitor to the Department of Materials Science under the Worshipful Company of Armourers and Brasiers' new distinguished visiting fellow scheme.
