Drug discovery and development affects various aspects of human health and dramatically impacts the pharmaceutical market. However, investments in a new drug often go unrewarded due to the long and complex process of drug research and development(R&D). With the advancement of experimental technology and computer hardware, artificial intelligence(AI) has recently emerged as a leading tool in analyzing abundant and high-dimensional data. Explosive growth in the size of biomedical data provides...  相似文献

近年来,人们对通过人工智能(AI)技术解决化学逆合成预测问题产生了巨大的兴趣。与化学家和基于规则的专家系统进行的逆合成预测不同,AI驱动的逆合成预测自动从现成的实验数据集中学习化学知识,以预测反应和逆合成路径。这提供了解决许多传统挑战的机会,包括专业知识过于繁杂、路线的长度过大和计算成本高。本文描述了当前AI驱动的逆合成预测的概况。我们首先讨论了化学逆合成的数学定义,并回顾了这个问题中的研究挑战。然后,我们回顾相关的AI技术和最新进度,以实现逆合成预测。此外,我们提供了逆合成系统不同部分的全面分类,并调查了AI方法如何重塑每个子模块。最后,我们讨论了未来有希望的研究领域。  相似文献

氧化还原液流电池(RFB)被认为是最高效的电网级大规模电化学储能技术,随着能源危机和环境污染的加剧,其引起广泛的关注。电荷传输性质是与储能装置的电化学性能有关的关键因素。通常通过调节材料形态和尺寸有效地减小离子的扩散距离,进而提高离子的扩散系数和电子的传递效率。纳米炭具有特殊的微结构和电子结构,并能呈现出众多奇异的物化特性,例如高离子电导、优异的导热性和出色的机械性能,其在电化学储能中起着不可或缺的作用。调控碳的微观结构是改善其电子和离子传输行为的有效策略。本文回顾了纳米炭在RFB中的功能,特别是着眼于电极(悬浮电极)和双极板(集电极)中使用的纳米炭材料的改性和设计,其可提高能量效率、功率密度和流动池的稳定性。希望对纳米炭材料在氧化还原液流电池中的应用进行更全面系统的介绍,可为高性能氧化还原液流电池的设计提供新的视角。  相似文献
