  • 10Nov

    Assoc. Prof. Boonrat Lohwongwatana, Department of Metallurgical Engineering, Chulalongkorn University, Thailand, and CEO and Co-founder of Meticuly.

    Overview of a 5-year journey starting from fundamental metallurgical and materials research on titanium 3D printing using Selective Laser Melting (SLM), in-situ biological cellular responses on materials, animal studies, cadaveric studies, finite element analysis on implant functionality, cyclical and range-of-motion bio-mechanics tests, human clinical investigations, and ultimately to achieving the USFDA 510(k) approval leading to adoption in 700+ human clinical cases in Asia. The talk then shifts into current metallurgical challenges in additive manufacturing, such as how to achieve superior as-printed properties which require significant improvements on laser melting parameters and melt-pool strategies that include simultaneous heat treatment, in-situ localised vitrification for glass forming alloy compositions, and data-driven manufacturing, such as on-the-fly analysis of layer-by-layer visual and thermal information that would predict the validity of the implant during production. Towards the end, the floor is opened to entrepreneurial and spin-off discussions on how the aforementioned scientific and technological steps were financially tied with fundraising steps (seed, series-A and series-B rounds). Research and testing for real world application in this case were extremely costly. It became necessary and strategic to execute them in stages with commercial milestones that were palatable to investors and de-risked the enterprise.

    Speaker: Pavel Janos, Faculty of Environment, J. E. Purkyne University in Usti nad Labem, Czech Republic

    At the turn of the century, an ability of nanostructured materials (typically nanocrystalline metal oxides) to destroy some chemical substances was discovered and exploited (among others) for the decontamination of highly toxic compounds, such as chemical warfare agents (CWAs). These active nanomaterials were called reactive sorbents (RSs). We proved that the RSs degradation efficiency towards CWAs outperforms conventional decontamination agents used by the NATO armies. Using cerium oxide prepared by precipitation/calcination route, we extended the application area of RSs to the degradation of structurally similar but chemically more stable environmental pollutants – organophosphate pesticides. It was shown that nanostructured cerium oxide is also effective in accelerating the cleavage of phosphoester bonds in other compounds with crucial importance for living organisms. We proposed the mechanisms of the hydrolytic cleavage of phosphodiester bonds in cAMP (cyclic adenosine monophosphate) in the presence of cerium oxide; cAMP is often used as a DNA simulant. We identified the characteristics/properties of cerium oxide responsible for its nanozymatic (phosphodiesterase-mimetic) ability.

    In the lecture, we will discuss the applications of nanocrystalline metal oxides as RSs and nanozymes. The main (dis)advantages and limitations will be introduced. New trends and possible future applications of nanocrystalline metal oxides will be presented.

    University members only.  If you are not a member of the Department of Materials Science, please contact an426@cam.ac.uk to discuss attending this talk because this room is in an area that is not accessible to non-members.

    To date, more than 80% of the energy demand is fed by fossil fuels resulting in excessive emissions of CO2. Hydrogen (H2) arose as an alternative energy source. Its notably energy density and environmentally friendly combustion makes it an attractive compound. However, the large demand of H2 is still fulfilled by fossil fuels what encourage to find sustainable ways to produce it.

    The combination of plasmonic nanoparticles (PNP) with catalytic metals gives rise to a new set of photocatalysts, enabling to exploit both sunlight harvesting and catalytic properties of individual constituent. However, there is a current debate on which geometrical-configurations
    between both metals is the most efficient. We addressed the question by preparing four Au- and Pd-based nanostructures with core-shell and core-satellite architectures and tested them in the generation of H2 out of Formic Acid.  Our experimental tests combined with optical simulations revealed that core-satellites reach higher light enhancements in comparison to their core-shell analogous. The capability to form  ́hotspots ́ between the two metallic entities leads to an increased local absorption rate, creating a larger number of excited carriers that participate in the photocatalytic process.

    Prof. Eduard Vives, Dept. Física de la Matèria Condensada, Universitat de Barcelona, Catalonia

    Solids with structural first-order phase transitions are being considered as candidates for elastocaloric refrigeration due to its large latent heat and the fact that applying mechanical stress is relatively easy compared to the alternatives based on electric or magnetic fields.

    For the case of metallic alloys exhibiting martensitic transitions, it is known that the dynamics proceeds by avalanches: its discontinuous in time and highly inhomogeneous. This can have deep implications in the design of future devices, especially if one is interested in small size and high frequency actuators.

    In this seminar I will review some recent experimental results on the dynamics of martensitic transitions in Cu-based alloys, obtained by Acoustic Emission detection, optical imaging of strain maps and infrared imaging. These techniques allow to track the position of the moving interface fronts and the corresponding heat sinks and sources.

  • 07Jun

    Prof. Raynald Gauvin, Department of Mining and Materials Engineering, McGill University

    This seminar will present the scanning transmission electron microscope (STEM) SU-9000 from Hitachi which characterizes thin and massive samples with electrons beam energies ranging from 0.1 to 30 keV. This microscope is equipped with an electron energy loss spectroscopy (EELS) detector which allows the detection of Lithium. High spatial resolution images are possible with a resolution of 0.16 nm. Many examples will be presented on Li materials and on nano-materials. This microscope is equipped with a EDS detector of lithium (Extreme, Oxford Instrument) and the microanalysis of lithium compounds, which is very difficult and challenging, will also be covered. The preparation of thin films by focus ion beam (FIB) for high spatial resolution images in STEM will be also shown with the newly acquired Hitachi NX-5000 FIB.
