Accelerating Multicomponent Phase-coexistence Calculations with Physics-informed Neural Networks

3/4/2026 | Michael Webb (Princeton University)

Accurate phase coexistence characterization is critical for designing and optimizing systems and processes involving multiple components, yet traditional methods are often slow and computationally expensive. To overcome this, a machine learning workflow grounded in physical principles was developed to streamline and speed up these calculations.

Higher-order Continuum Models for Twisted Bilayer Graphene

2/26/2026 | M. Luskin (U. Minnesota)

Twisted bilayer graphene (TBG) is obtained by stacking two sheets of graphene on top of each other with a relative twist. At incommensurate twist angles, TBG is not periodic and thus does not admit a Brillouin zone or periodic branches of spectrum. Instead, the atoms form a structure which is approximately periodic with respect to the so-called moire lattice, whose unit-cell area is inversely proportional to the square of the twist angle.

Van der Waals Quantum Dots on Layered Hexagonal Boron Nitride

2/26/2026 | T. Norris and Z. Mi (University of Michigan)

Semiconductor quantum dots (QD) promise unique electronic, optical, and chemical properties, which can be exquisitely tuned by controlling the composition, size, and morphology. Semiconductor QDs have been synthesized primarily via two approaches, namely, epitaxial growth and wet-chemical synthesis.

Controlling Quasi-1D Excitons by Magnetic Order

2/26/2026 | M. Kira (University of Michigan)

Quantitative experiment–theory proof is presented that excitonic correlations can be switched through magnetic order. By probing internal Rydberg-like transitions of excitons in the magnetic semiconductor CrSBr, their binding energy and a dramatic anisotropy of their quasi-one-dimensional orbitals was revealed manifesting in strong fine-structure splitting.

Emerging Microelectronic Materials by Design

2/20/2026 | James Rondinelli and Wei Chen (Northwestern University)

The increasing demands of sustainable energy, electronics, and biomedical applications call for next-generation functional materials with unprecedented properties. Of particular interest are emerging materials that display exceptional physical properties, making them promising candidates for energy-efficient microelectronic devices.

Predicting and Accelerating Nanomaterials Synthesis using Machine Learning Featurization

2/20/2026 | Christopher Hinkle (U. Notre Dame)

Materials synthesis optimization is constrained by serial feedback processes that rely on manual tools and intuition across multiple siloed modes of characterization. Feature extraction of reflection high energy electron diffraction (RHEED) data with machine learning has been automated and generalized to establish quantitatively predictive relationships in small sets (∼10) of expert-labeled data, saving significant time on subsequently grown samples.

Learning Molecular Mixture Property Using Chemistry-Aware Graph Neural Network

2/20/2026 | James Rondinelli and Wei Chen (Northwestern University)

Recent advances in machine learning (ML) are expediting materials discovery and design. One significant challenge facing ML for materials is the expansive combinatorial space of potential materials formed by diverse constituents and their flexible configurations. This complexity is particularly evident in molecular mixtures, a frequently explored space for materials, such as battery electrolytes.

Data-driven Framework for the Prediction of PEGDA Hydrogel Mechanics

2/12/2026

Poly(ethylene glycol) diacrylate (PEGDA) hydrogels are biocompatible and photo-cross-linkable, with accessible values of elastic modulus ranging from kPa to MPa, leading to their wide use in biomedical and soft material applications. However, PEGDA gels possess complex microstructures, limiting the use of standard polymer theories to describe them. As a result, we lack a foundational understanding of how to relate their composition, processing, and mechanical properties.

Active and Passive Crosslinking of Cytoskeleton Scaffolds Tune the Effects of Cell Inclusions on Composite Structures

2/12/2026 | R. Anderson (U. San Diego), J. Ross (Syracuse), M. Rust (U. Chicago), M. Valentine (UCSB), M. Das (Rochester)

Incorporating cells within active biomaterial scaffolds is a promising strategy to develop materials that can autonomously sense and respond. Using dynamic biocompatible scaffolds that can self-alter their properties would offer even greater avenues for actuation and control, but our understanding of the fundamental design principles of such complex materials remains limited.
