Symposium X—Frontiers of Materials Research

The Golden Age of Materials Innovations—From High-κ/Metal Gate to AI Hardware

High-ĸ/Metal Gates are ubiquitous in CMOS chips and are a product of intense collaborative research across academia and corporate labs. These new materials re-enabled a roadmap for CMOS scaling from FinFET (current) to Nanosheet (future) device architectures.  However, CMOS scaling is slowing down with performance benefits diminishing with each node. At the same time, the need for consuming data has gone up exponentially with deep learning-based AI algorithms being deployed for this purpose and run on specialized AI hardware such as graphical processing units (GPU). However, GPUs consume significant power since data transfer occurs from memory to processor. Resistive Processing Units (RPU) envision artificial neural networks mapped to arrays of non-volatile memory (NVM) elements that execute operations in-memory and constant time, thereby enabling significant power performance benefits. Many NVM elements are being evaluated as RPU but suffer from significant non-idealities and are therefore ripe once again for innovation and collaboration across academia and industry.

Efficient Recycling and Regeneration of E-Mobility Components and Materials

A sustainable future e-mobility requires an efficient circularity of the energy converters with a programmable long lifetime.
Electrochemical energy conversion processes in batteries, fuel cells and electrolysers require full reversibility of local effects, defect formations, phase segregations and redox reactions. Therefore, regenerative or self-repairing materials have to be developed to produce long-lasting devices.

The design of sustainable high performance materials is based on theoretical predictions, life cycle assessment and a profound knowledge on composition-structure-property relationships, defect chemistry, ion mobility assessment and the criticality analysis of applied elements to improve the cycle life of future batteries, fuel cells and electrolysers.

Socially-Directed Science and Technology — Opportunities and Challenges for the Field of Materials Science and Engineering

We live in an era rife with social inequities and planetary perils, as the collective impact of humans threatens life on earth as we know it, radically transforming our societies and ecosystems. While science and technology and, in particular, the field of materials science and engineering has contributed enormous benefits to humanity, simultaneously it has also been entangled with and contributed to these formidable challenges. In re-imagining a more equitable and sustainable future, let alone bringing it into reality, we must acknowledge, interrogate and understand the historical context, root causes and systemic structures that underpin the scientific and technological enterprise and our discipline, as well as the institutions of higher learning which serve as its foundation.

Science and technology, rooted in social inquiry, inclusion and equity, is more important than ever to our survival, let alone progress. This presentation will discuss a socially-directed approach to science and technology with a focus on the field of materials science and engineering and integration with humanistic fields such as history, the social sciences, including science, technology and society studies; social justice; and civic design and community-based participatory research, in order to interrogate, understand and shape technologically-driven societal impact towards more equitable, ethical and sustainable outcomes. Emerging areas will be considered such as circular materials design for socioresilient infrastructure, the Anthropocene, materials and environmental in/justice, fire safety materials, social inequity and disparate risks to fire, social life cycle assessment and the case of shipbreaking, ethics and socially-directed computational materials.

Designing Biology

Biology is the most powerful technology on the planet. It’s ability to self-repair, self-replicate and make atomically precise structures is unparalleled among manufacturing technologies. At Ginkgo, we are passionate about harnessing the power of biology by designing it. Unfortunately, despite significant advancements in recent years, the tools and technology for biological design remain woefully inadequate relative to the potential of biological technology. Our limited understanding of how biology works means that, for now, biological design is essentially a search problem. At Ginkgo, we are leveraging automation and software to build a genetic engineering foundry that allows us to more cheaply and scalably search potential biological design space for functional organism designs. In particular, I will highlight the value of combining computer-aided engineering software tools, cheap gene synthesis and high resolution-accurate mass LCMS to develop engineered microbes. Then, I'll discuss how we applied these technologies for improving a "living medicine" for the treatment of a metabolic disorder.

Intellectual Property Filing Strategy, Portfolio Management and Licensing of Material-Related Technologies

A key understanding of intellectual property strategies is essential to build meaningful intellectual property portfolios for material-related technologies. Intellectual property portfolios typically consist of a combination of both patents and trade secret/know-how information. Unlike other technologies, patent filings for material-related technologies such as batteries, catalysts and functionalized materials require additional data, description and documentation to ensure broad protection of the underlying technology.  While patent application filings for mechanical, electrical and software technologies do require a detailed description of the structure and operation of the technology to enable recreation by one of skill in the art, material-related technologies additionally require demonstration of a strong understanding of the underlying mechanism behind the invention coupled with strong support of laboratory data.  Any shortcoming in this area will result in narrow protection covering only the specific aspects of the invention supported by the data provided. This presentation will focus on best practices to ensure proper intellectual property protection for material-related technologies. Additionally, we will discuss how to build intellectual property portfolios around fundamental technologies with an eye toward protection of commercial interests and licensing.

About Frederick Mau

Mau has the position of Intellectual Property Counsel with Toyota Motor North America, Inc.  His job responsibilities include all patent filing, prosecution and patent portfolio management (domestic & foreign) for all Advanced Research, Vehicle Engineering and Manufacturing business units within North America.  Furthermore, Mau handles and/or advises on many other Intellectual property-related matters, which may include patent disputes, patent clearance studies, open source software, intellectual property matters relating to contracts, business establishment and support of IP lobbying efforts for Toyota Government Affairs.  In addition to his role as Intellectual Property Counsel for TMNA, Mau  also oversees the licensing activity for Toyota IP Solutions as Director of Patent Licensing.

Extreme Wave Interactions in Metamaterials with Broken Symmetries

In this talk, I discuss our recent discoveries in electromagnetics, nano-optics and acoustics showing how suitably tailored meta-atoms and their arrangements open exciting avenues to enable extreme phenomena and new technology based on light, radio-waves and sound. In particular, I discuss venues in which broken symmetries play a pivotal role in establishing emerging phenomena in metamaterials, from geometrical asymmetries and generalized forms of chirality, to time-reversal symmetry breaking and parity-time symmetry. Our work shows how symmetry concepts offer interesting tools to break Lorentz reciprocity and realize isolation without the need of magnetic bias, based on broken time-reversal symmetry induced by mechanical motion, spatio-temporal modulation and/or nonlinearities. Broken symmetries in space and space-time open also the opportunity to induce topological order in metamaterials. The opportunities offered by hybrid metamaterials combining classical photonic material platforms with 2D and quantum materials characterized by exotic lattice symmetries will also be discussed. Finally, the role of parity-time symmetry and non-Hermitian physics in enabling broadband wave manipulations beyond the limits of passive systems will be outlined. In the talk, I will outline the impact of these concepts from basic science to practical technology, from classical waves to quantum phenomena.
