Key Takeaways

• Human development has evolved through distinct material ages, and we may now be entering a new “Materials Age” where material properties can be engineered from the atomic level.
• Dr. Joshua Young’s company, Matlantis, utilizes advanced machine learning techniques to accelerate materials discovery by simulating atomic interactions.
• With cloud-based simulations, researchers can efficiently identify promising materials for diverse applications, reducing the time and resources needed for experimentation.

Exploring a New Materials Age

The evolution of human civilization can be marked by various material ages, beginning with the Stone Age and progressing through the Bronze and Iron Ages, culminating in the Industrial Revolution. This legacy of technological advancement has led to the emergence of the “Materials Age,” where the focus is not just on discovering materials but creating them based on desired properties like strength, flexibility, and conductivity.

Historically, the transition between these ages was gradual, with cultures overlapping in their material use. Today, scientists can specify the characteristics they need and work to develop materials that meet those specifications. This shift represents a significant turning point in materials science, moving from asking, “What can we create with this material?” to, “What material do we need to create this?”

Pioneering this change is Dr. Joshua Young, a Senior Application Scientist at Matlantis. His company integrates atomistic simulations with machine learning to provide a new approach to materials research. Using a method called Density Functional Theory (DFT), researchers can model systems at the atomic level, calculating properties like energy and conductivity. However, the computational expense of DFT limits its scalability.

Machine Learning Interatomic Potentials (MLIPs) offer a solution by allowing researchers to train models through extensive DFT calculations. Once trained, these models can predict atomic interactions rapidly, making it feasible to analyze larger systems efficiently compared to traditional methods. While MLIPs cannot provide detailed electronic properties like DFT, they can identify potential structures for further examination.

Matlantis utilizes a platform powered by a universal MLIP known as PFP (Preferred Potential). This model was trained on around 62 million DFT computations across various chemical compositions. By intelligently selecting representative examples of atomic arrangements, the platform can predict new materials’ properties and interactions.

The cloud-based nature of Matlantis means users bypass the need for extensive computational resources. The company also provides high-touch customer support, ensuring that research questions can be translated into effective simulations. Whether exploring defects in semiconductor materials or studying ion movement in batteries, Matlantis streamlines the discovery process.

The platform allows researchers to reduce extensive candidate lists for new materials. Instead of synthesizing millions of candidates, researchers can utilize AI-powered simulations to narrow down to the most promising possibilities. Integration of AI coding agents enables researchers to express material specifications in natural language, making the search for innovative materials more accessible.

For example, a researcher can instruct the AI to identify materials that are strong, lightweight, heat resistant, and transparent. Through rapid exploration of chemical and structural possibilities, unpromising candidates can be identified and discarded swiftly, allowing focused DFT analyses on the best prospects.

While current capabilities may not yet replicate the advanced atom-by-atom manufacturing seen in science fiction, the strides taken by Matlantis signal significant progress. With AI and advanced simulations, the potential exists to revolutionize materials discovery, paving the way for breakthroughs across various domains such as semiconductors, batteries, chemicals, and pharmaceuticals.

In summary, the transition into this new Materials Age symbolizes a paradigm shift in how materials are conceptualized, developed, and produced, combining the powers of simulation, machine learning, and human expertise. Researchers stand at the forefront of this exciting evolution, transforming materials science from a field of experimentation to a strategic discipline of design.
