DeepModeling

DeepModeling community has officially released Uni-Mol2, which is currently the largest 3D molecular representation foundation model. The largest version of Uni-Mol2 has a parameter scale of 1.1 billion and has been pre-trained on 800 million molecular conformations, demonstrating excellent performance in multiple molecular property prediction tasks. This achievement not only provides a powerful tool for deep learning research in the field of molecular science but also lays a solid experimental foundation for exploring larger-scale molecular pre-training models. At the NeurIPS 2024 conference currently being held in Vancouver, Canada, Uni-Mol2, as an accepted paper, has also received extensive attention.

Recently, Associate Professor Xu Yang from the School of Science at Shenyang Aerospace University, in cooperation with Professor Fei Du and Professor Yi Zeng from Jilin University and other scholars, conducted an in-depth study on the cubic phase K₃SbS₄ solid-state electrolyte based on the DeePMD method. The related research results were published in the journal "Chemistry of Materials" under the title "Cl-Doped Cubic K₃SbS₄ as a Solid-State Electrolyte for K-Ion Batteries with Ultrafast Ionic Conductivity" (DOI: 10.1021/acs.chemmater.4c02575).

On October 17, 2024, the research paper titled "Entropy in catalyst dynamics under confinement" by the AI4EC Lab/Professor Jun Cheng's research group from Xiamen University was published online in the international journal Chem. Sci. The first author of the paper is Qiyuan Fan(currently a teacher at the School of Chemistry and Chemical Engineering, Shanxi University). This work was completed under the guidance of Professor Jun Cheng and with the guidance and support of Academician Zhongqun Tian, Academician Xinhe Bao from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Academician Weinan E from Peking University, and Professor Ye Wang from Xiamen University.

GPUMD is an efficient domestic molecular dynamics simulation software developed and maintained by Professor Zheyong Fan from Bohai University. The software first released its public version 1.0 in 2017 [Computer Physics Communications 218, 10 (2017)] and has currently been iterated to version 3.9.4. GPUMD includes both commonly used empirical potentials and NEP (Neuroevolution Potential) machine learning potentials. Up to now, GPUMD has been used by thousands of users in many countries around the world and has attracted dozens of researchers to participate in its development. It is widely applied in fields such as heat and mass transfer, mechanical properties, structural phase transitions, irradiation damage, spectroscopy, and catalysis. Related achievements have been published in top academic journals such as Nature, Nature Communications, J. Am. Chem. Soc, ACS Nano, Phys. Rev. Lett, J. Mech. Phys. Solids, J. Chem. Theory Comput., Phys. Rev. B, and J. Chem. Phys.

In June 2024, GPUMD&NEP joined the DeepModeling community. As an innovative and highly efficient MD simulation and machine learning potential function tool, it further provides support for the Materials Genome Project and the AI4S community.

With the growing market demand for efficient and safe rechargeable batteries that can operate under extreme temperature conditions, the rapid and accurate evaluation of key properties of electrolyte molecules has become particularly important. A recent paper titled "A Knowledge–Data Dual-Driven Framework for Predicting the Molecular Properties of Rechargeable Battery Electrolytes," published in Angewandte Chemie International Edition, details an innovative approach known as the "Knowledge–Data Dual-Driven Framework" (KPI) specifically designed to predict the molecular properties of battery electrolytes, including melting point (MP), boiling point (BP), and flash point (FP). The research team skillfully combined deep learning techniques with domain-specific chemical knowledge, supported by large-scale datasets, significantly enhancing the accuracy and efficiency of predictions. In this framework, the Uni-Mol model plays a central role, demonstrating great potential in predicting the properties of electrolyte molecules and providing strong support for the development of next-generation high-performance batteries.

On August 19, 2024, Linlin Hou, Hongxin Xiang, and Xiangxiang Zeng from Hunan University, in collaboration with Li Zeng from the Shanghai Institute of Materia Medica, published a research article titled "Attribute-guided Prototype Network for Few-shot Molecular Property Prediction" in Briefings in Bioinformatics. This study introduced an Attribute-guided Prototype Network (APN), which innovatively combines high-level molecular fingerprints with deep learning algorithms, significantly improving the accuracy of molecular property prediction in limited-sample scenarios. This breakthrough opens a new direction for few-shot learning in drug development.
