Dynamic Restructuring of ZrO2–Cu Interfaces Under CO2 Hydrogenation Conditions
The catalytic performance of inverse oxide–metal systems is strongly influenced by their structural dynamics under reaction conditions. In this study, ab initio molecular dynamics simulations were carried out to investigate temperature-induced restructuring at ZrO2-on-Cu interfaces between 450 and 600 K. The simulations reveal reversible Zr–O bond rearrangements that generate transient low-coordination Zr sites with enhanced Lewis acidity. These dynamically formed sites lower the CO2 activation barrier by up to 0.31 eV compared with static interface models. Time-averaged free energy profiles indicate a 2.7-fold increase in predicted methanol formation rates when dynamic effects are included. In contrast, simulations constrained to static geometries systematically underestimate catalytic activity. The results demonstrate that interface flexibility plays a decisive role in stabilizing key intermediates and should be explicitly considered when modeling inverse catalysts for CO2 hydrogenation

Synergy Prediction of Lung Cancer Targeted Drugs Fusing Transcriptomic Data and Graph Networks
Lung cancer remains the leading cause of cancer-related mortality worldwide, necessitating the development of advanced therapeutic strategies. Combination therapy, the administration of two or more drugs, has emerged as a critical approach to overcome drug resistance and enhance therapeutic efficacy compared to monotherapy. However, experimental screening of all possible drug combinations is cost-prohibitive and time-consuming due to the combinatorial explosion of potential pairs. In this study, we propose a novel deep learning framework that predicts drug synergy specifically for lung cancer by fusing transcriptomic data with graph neural networks. The model integrates the chemical structural information of drugs, captured through graph convolutional networks, with the genomic features of cancer cell lines derived from high-throughput transcriptomic profiles. By employing an attention-based fusion mechanism, the architecturedynamically weighs the importance of molecular substructures and gene expression signatures to predict synergy scores. We evaluated our model on large-scale benchmark datasets, demonstrating superior performance over state-of-the-art machine learning baselines. The results indicate that incorporating cell-line-specific transcriptomic data significantly improves prediction accuracy, offering a promising computational tool to accelerate the discovery of effective combination therapies for non-small cell lung cancer and small cell lung cancer subtypes.
