Title:
Sunlight to X: Advanced Catalysis for Sustainable Chemical and Fuel Synthesis
Abstract:
The immense power of sunlight, with just two hours of solar irradiation being sufficient to power the entire planet for a year, underscores the potential of solar energy. While commercial technologies exist for converting sunlight to electricity, achieving net zero emissions requires decarbonizing sectors that are hard to abate, such as long haul aviation and maritime, and the chemical and steel industries. This presentation delves into the role of advanced catalysis in harnessing solar energy to synthesise chemicals and fuels sustainably. Advanced catalysts, characterised by their unique intrinsic properties including modified optical and electronic characteristics, significantly enhance the efficiency and selectivity of solar-driven chemical processes. Our research uses the entire solar spectrum, utilising UV and visible light for photocatalytic reactions and infrared radiation for thermal catalysis. These processes facilitate critical reactions like water splitting for hydrogen production, CO2 reduction, NOx reduction, and CO2 hydrogenation. Key advancements include our work with advanced catalysts such as ZnxIn2S3+x, which have elucidated the interplay between structure, activity, and selectivity—optimising the conversion of furfuryl alcohol into hydrogen and hydrofuroin, a potential jet fuel. Additionally, our integration of a solar-thermal reactor with a photovoltaic-electrolyser demonstrates the practical application of our research, optimising the solar-driven reduction of CO2 with hydrogen to produce methanol. This work not only demonstrates the versatility of solar energy in generating clean fuels and value-added organic transformations but also marks a significant advancement in the application of advanced catalytic materials for solar energy conversion. By providing viable alternatives to fossil fuels and advancing catalysis technologies, our findings contribute substantially to global energy sustainability.

Title:
Developing and applying new tools to understand how electrochemical devices function and fail – from batteries, supercapacitors to gated electronics.
Abstract:
Rechargeable batteries have been an integral part of the portable electronics revolution and are now playing a critical role in transport and grid applications to help mitigate climate change. However, these applications come with different sets of challenges. New technologies are being investigated and fundamental science is key to producing non-incremental advances and to develop new strategies for energy storage and conversion.
This talk will focus on our own work to develop NMR, MRI and new optical methods that allow devices to be probed while they are operating, from the local, to particle and then cell level. This allows transformations of the various cell materials to be followed under realistic conditions without having to disassemble and take apart the cell. Starting with local structure and dynamics, as measured by NMR, I will then show - with new optical methods - how the different dynamics can result in different intercalation mechanisms. A good example is our work on LiCoO2, where via optical approaches we were able to directly visualize movement of phase fronts as lithium is removed and inserted into this material. New results on solution-based redox flow and extremely high-rate batteries will be outlined; I will then illustrate how our new metrologies can be extended to study a wider range of electrochemical systems.

Title:
Optical artificial intelligence enabled by functional materials
Abstract:
Artificial intelligence based on ever-increasing computing power including neuromorphic computing has heralded a disruptive horizon in many ways of our life. The concept of optical artificial intelligence has demonstrated its unique advantage in terms of the ultrafast computational speed and ultralow energy consumption. In pursuing this vision, the diffractive neural network harvesting the spatial connection among digitised pixels is one of the promising emerging technologies in this race as it offers a potential for ultrafast neuromorphic computing power with a high neural density. Invented by Dennis Gabor in 1948, holography offers a diffractive approach to reconstructing both the intensity and phase information of an object under investigation. In the area of optical holography demonstrated in 1962, this technology can be multiplexed in many physical domains, which is advantageous for high connectivity of holographic neural networks. With the advanced function materials including graphene, topological and perovskite composites, I will show ultrafast artificial intelligence enabled by optical nanoscale holograms fabricated by femtosecond laser lithography as well as temporal optical inferencing.

Title:
Next Generation Moiré Quantum Matter
Abstract:
The understanding of strongly-interacting quantum matter has challenged physicists for decades. The discovery five years ago of correlated phases and superconductivity in magic angle twisted bilayer graphene has led to the emergence of a new materials platform to investigate strongly interacting physics, namely moiré quantum matter. In this talk I will review recent experiments on next generation moiré quantum matter, both twisted multilayer graphene systems as well as dual (or asymmetric) moiré systems. In particular, first I will briefly discuss our experiments on magic-angle twisted multilayer graphene as a family of robust moiré superconductors. Second, I will discuss the engineering of moiré quasicrystals and a new type of unconventional ferroelectricity and electron ratchet in asymmetric moiré systems.

Title:
Ferroelectric Thin Films for Piezoelectric MEMS and Three Dimensional Non-volatile Memory
Abstract:
In the first part of the talk, the use of ferroelectric films for low voltage piezoelectric microelectromechanical systems (MEMS) will be discussed. The key figures of merit for actuators and energy harvesting will be described, with emphasis on how to achieve these on practical substrates. For example, control of the domain structure of the ferroelectric material allows the energy harvesting figure of merit for the piezoelectric layer to be increased by factors of 4 – 10. Likewise, control of crystallographic orientation and substrate clamping enables large increases in the figure of merit for actuators. Examples of integration into MEMS structures will also be given, including miniaturized ultrasound systems for imaging and particle manipulation, low frequency and non-resonant piezoelectric energy harvesting devices, and adjustable optics. The second part of the talk will discuss new families of ferroelectric materials available for integration with CMOS electronics. These new materials, including Hf1-xZrxO2, Al1-xScxN, Al1-xBxN and Zn1-xMgxO, offer the possibility of new functionalities. This talk will discuss the possibility of exploiting the 3rd dimension in microelectronics for functions beyond interconnects, enabling 3D non-von Neumann computer architectures exploiting ferroelectrics for local memory, logic in memory, digital/analog computation, and neuromorphic functionality. This approach circumvents the end of Moore’s law in 2D scaling, while simultaneously overcoming the “von Neumann bottleneck” in moving instructions and data between separate logic and memory circuits. Computing accounts for 5 – 15% of worldwide energy consumption. While recent efficiency gains in hardware have partially mitigated the rising energy consumption of computing, major gains are achievable in a paradigm shift to 3D computing systems, especially those that closely couple memory and logic. Emphasis will be placed to the wurtzite family of ferroelectric films as potential candidates for non-volatile memory to address this problem.

Title:
Perovskite Solar Cells: The New Frontier of Solar Energy
Abstract:
Meeting the escalating electricity demands of our advancing society, particularly at the terawatt scale, requires achieving high power conversion efficiency and low cost per peak watt in solar cell technology simultaneously. Prior to the introduction of perovskite solar cells, only a limited array of materials and technologies could meet both criteria. This presentation traces the evolution toward the development of practical solid-state perovskite solar cells. Beginning with an overview of initial technologies, the discussion progresses to the emergence of solid-state perovskite solar cells. Early efforts involved the use of quantum dot inorganic materials, such as nanocrystalline lead sulfide, as light harvesters. Despite their potential, these materials encountered significant challenges, primarily surface-defect-mediated recombination. Acknowledging these limitations, methylammonium lead triiodide (MAPbI3) perovskite emerged as an alternative to inorganic quantum dots. However, initial implementations as sensitizers in liquid-electrolyte-contained structures yielded disappointing results, with efficiencies as low as 3-4% in 2009 and the dissolution of MAPbI3. A breakthrough occurred in 2012 when a pioneering study demonstrated a 9.7% efficient and 500-hour-stable perovskite solar cell, leveraging MAPbI3 and a solid hole transporting material. This pivotal advancement rendered perovskite solar cells a viable and durable technology. Subsequent years witnessed rapid growth in perovskite photovoltaic research, with efficiencies approaching 27% using FAPbI3, surpassing existing technologies. Current research endeavors focus on enhancing stability and exploring tandem structures for electricity generation in both terrestrial and space applications. The perovskite solar cell stands poised as the most promising energy solution, with its potential impact on sustainable energy surpassing current expectations once stability and lead immobilization challenges are effectively addressed.

Electronic skins for robotics and wearables
Abstract:
The human skin, functioning as a large-area, multi-point, multi-modal, and flexible sensor, serves as inspiration for the development of electronic skin in robots, aimed at detecting pressure and thermal patterns simultaneously. With advancements in flexibility, electronic skin has transcended its initial use in robotics and expanded into next-generation wearable technologies for humans. This evolution has now reached a stage where ultra-thin semiconductor membranes can be directly attached to the skin. This seamless integration of electronics with human skin allows for continuous health monitoring over prolonged periods, facilitating personalized medical care. The ultimate goal of electronic skin is to non-invasively capture human activities in natural settings, fostering interactive synergy between electronic and human skin. In this presentation, I will discuss recent advancements in stretchable thin-film electronics, focusing on their applications in robotics and next-generation healthcare wearables. I will also address the challenges faced in this field and highlight the potential future prospects of electronic skin.

Electronic skins for robotics and wearables
Abstract:
The human skin, functioning as a large-area, multi-point, multi-modal, and flexible sensor, serves as inspiration for the development of electronic skin in robots, aimed at detecting pressure and thermal patterns simultaneously. With advancements in flexibility, electronic skin has transcended its initial use in robotics and expanded into next-generation wearable technologies for humans. This evolution has now reached a stage where ultra-thin semiconductor membranes can be directly attached to the skin. This seamless integration of electronics with human skin allows for continuous health monitoring over prolonged periods, facilitating personalized medical care. The ultimate goal of electronic skin is to non-invasively capture human activities in natural settings, fostering interactive synergy between electronic and human skin. In this presentation, I will discuss recent advancements in stretchable thin-film electronics, focusing on their applications in robotics and next-generation healthcare wearables. I will also address the challenges faced in this field and highlight the potential future prospects of electronic skin.

Title:
Towards Chips that Rewire Themselves? …How Novel Material-System Co-Design can enable them
Abstract:
Ultra-low energy and area-efficient electronic systems are required to enable untethered computing at the edge of IoT. To realize self-learning edge-AI systems, conventional solely software-driven deep-learning neural networks becomes a major roadblock due the excessive energy expense of training. Hence, fundamental hardware change is likely needed. In this talk, we review our recent material innovations (E.g. Ferroelectric oxides and 2D Material) and we show how close coupling with new micro-architecture innovations (E.g. New memory physical layout and Monolithic 3D IC) may significantly accelerate in-memory computation. We explore wafer-level solution-processed CMOS-compatible use of 2D Material (MoS2/WSe2) to enable high-endurance memristors that can have properties superior to conventional oxide RRAMs. We discuss the use and enabling of multi-gated HZO-based low-thermal-budget ferroelectric oxide memtransistors for new reconfigurable non-volatile logic and interconnect. In co-operation with specific system-level innovations, we review material-system co-design in data encoding for deep convolution neural network. We show through material-device-aware data encoding, error correction, and novel physical memory layout (staggered + Manhattan arrays), that aim to simplify in-memory data process, one can significantly manage variabilities while accelerating convolution deep neural network operations and offer substantial low-energy opportunities towards reconfigurable Edge-AI systems.
