Ion channels are generally allosteric proteins, involving specialized stimulus sensor domains conformationally linked to the gate to drive channel opening. Temperature receptors are a group of ion channels from the transient receptor potential family. They exhibit an unprecedentedly strong temperature dependence and are responsible for temperature sensing in mammals.

Bioabsorbable internal fixation is a well-accepted modality that is especially suitable for application in craniosynostosis. When first introduced, high rates of adverse tissue reactions were observed that have since been ameliorated with more biocompatible polymer formulations. However, the phenomenon has not entirely disappeared, and such reactions remain vexing.

While machine learning (ML) models have been able to achieve unprecedented accuracies across various prediction tasks in quantum chemistry, it is now apparent that accuracy on a test set alone is not a guarantee for robust chemical modeling such as stable molecular dynamics (MD). To go beyond accuracy, we use explainable artificial intelligence (XAI) techniques to develop a general analysis framework for atomic interactions and apply it to the SchNet and PaiNN neural network models. We compare these interactions with a set of fundamental chemical principles to understand how well the models have learned the underlying physicochemical concepts from the data.

The electrochemical conversion of CO into high value-added carbon materials by molten salt electrolysis offers a promising solution for reducing carbon dioxide emissions. This study focuses on investigating the influence of molten salt composition on the structure of CO direct electroreduction carbon products in chloride molten salt systems. Using CaO as a CO absorber, the adsorption principle of CO in LiCl-CaCl, LiCl-CaCl-NaCl and LiCl-CaCl-KCl molten salts was discussed, and the reasons for the different morphologies and structures of carbon products were analyzed, and it was found that the electrolytic efficiency of the whole process exceeded 85%.
