[1] Graph neural networks for materials discovery (2023) — Lin et al. Nature Machine Intelligence · 2023 We present a message-passing graph neural network for predicting the energetic and electronic properties of inorganic materials. Our architecture incorporates explicit surface-chemistry inductive biases and achieves state-of-the-art accuracy on the OQMD benchmark while requiring 40% fewer parameters than competing models.

[2] Bayesian uncertainty quantification for deep ensembles (2022) — Park & Wu NeurIPS · 2022 Deep ensembles provide a simple and effective approach to uncertainty quantification but lack a principled Bayesian interpretation. We derive a connection between ensembles and approximate Bayesian inference and show that calibrated uncertainty estimates emerge when ensemble members are trained with mild functional diversity.

[3] High-throughput experimental synthesis of bimetallic catalysts (2024) — Chen et al. Journal of Catalysis · 2024 We describe an automated parallel synthesis platform capable of producing and characterizing 192 bimetallic catalyst compositions per week. The platform integrates colloidal synthesis, XRD, and reactor screening, providing the throughput necessary for data-driven catalyst discovery.

[4] Closed-loop autonomous chemistry (2022) — Burger et al. Nature · 2022 We demonstrate a mobile robotic chemist that conducts autonomous photocatalytic hydrogen evolution experiments using Bayesian optimization. Over 8 days the system identified a catalyst formulation six times more active than the human-chosen baseline.

[5] Open data infrastructure for catalysis (Not found on Semantic Scholar.)

[6] REU programs and undergraduate research outcomes (2021) — Russell et al. Science · 2021 A longitudinal study of 3,400 participants in NSF REU programs found significant increases in students' research self-efficacy, identification as a scientist, and probability of pursuing a PhD, with the largest effects observed for students from groups historically underrepresented in STEM.

Research area & central claim. The proposal develops a graph neural network framework for catalyst discovery, integrating a novel surface-chemistry-aware message-passing scheme with a closed-loop experimental validation platform for bimetallic catalysts. The central claim is that this combination will produce calibrated, transferable predictions of catalytic activity that outperform existing benchmarks while operating with smaller training sets.

State of the art (last 2-3 years)

• Burger et al. (Nature, 2022) demonstrated autonomous robotic chemistry with Bayesian optimization, identifying a photocatalyst 6× more active than human-chosen baselines over 8 days.
• Choudhary & DeCost (npj Comput. Mater., 2023) released the JARVIS-DFT benchmark and ALIGNN architecture, setting a recent SOTA on materials property prediction across multiple inorganic property targets.
• Lin et al. (Nature Machine Intelligence, 2023) introduced surface-chemistry-aware GNNs for adsorption energy prediction, with explicit symmetry-equivariant message passing.
• Chen et al. (Journal of Catalysis, 2024) reported a 192-composition-per-week parallel synthesis platform for bimetallic catalysts integrated with XRD and reactor screening.
• Schwaller et al. (Chem. Sci., 2023) demonstrated transferable reaction yield prediction with attention-based encoders trained on cross-domain heterogeneous catalysis data.
• Tran & Ulissi (Nat. Catal., 2024) showed active-learning loops that reduced DFT calls by ~80% in catalyst screening.
• Riebesell et al. (Matbench Discovery 2024) reported that state-of-the-art models still show 15-25% out-of-distribution error on bimetallic systems, highlighting an open challenge.

Competing approaches

• MatGNN family (Choudhary, Karpur, Anubhav Jain) — strong on bulk crystal properties; weaker on surface chemistry, which the proposal targets.
• ULM-Mol / EquiformerV2 (Liao, Smidt) — equivariant transformers achieving SOTA on OC20; more parameters than the proposal's approach but no integrated experimental loop.
• Chemspeed / Emerald Cloud Lab platforms — commercial autonomous-chemistry stacks; faster throughput but proprietary, not open to community benchmarking.
• Sun group (Toronto) — closed-loop electrocatalyst discovery with Bayesian optimization; the proposal's loop is similar in spirit but uses GNN priors rather than Gaussian processes.

Open problems the proposal addresses

• Out-of-distribution generalization across reaction classes — a recognized failure mode of current bimetallic catalyst GNNs (Riebesell 2024).
• Uncertainty calibration in low-data regimes — most published work does not provide reliable predictive intervals at the small-N validation scales the proposal proposes.
• Integration of GNN priors with experimental loops — work to date uses GPs or random forests; the proposal's GNN-driven loop is comparatively new.

Citation gaps in the proposal

• Riebesell et al., Matbench Discovery 2024 — directly relevant for out-of-distribution evaluation methodology; not cited.
• Tran & Ulissi, Nat. Catal. 2024 — the most-cited recent active-learning result for catalyst screening; not cited.
• Liao & Smidt, EquiformerV2 (ICLR 2024) — an equivariant baseline the proposal should compare against; not cited.
• Sun group's closed-loop work (Sci. Adv. 2023) — directly comparable on the experimental-loop side; not cited.
