Summary: This study electrochemically deposited gold nanoparticles (AuNPs) on the surface of coiled carbon nanotubes (CCNTs) modified carbon ionic liquid electrode (CILE) and used Nafion film to immobilize horseradish peroxidase (HRP), resulting in a modified electrode. The HRP immobilized on the AuNPs-CCNTs composite retained its biostructure and exhibited quasi-reversible electrochemical behavior on the Nafion/HRP/AuNPs-CCNTs/CILE. The electrocatalytic activities towards KBrO3 and NaNO2 were further investigated, and the apparent heterogeneous electron transfer rate constant (ks), charge transfer coefficient (a), and Michaelis-Menten constants (KappM) were calculated. The linear detection range for KBrO3 was 0.5 to 10.0 mmol.L-1 with a detection limit of 0.16 mmol.L-1, while for NaNO2, the current response showed two linear sections in the concentration range of 0.1 to 0.7 mmol.L-1 and 0.9 to 3.0 mmol.L(-)1 with a low detection limit of 0.03 mmol.L-1. The sensor was successfully used for the analysis of real water samples, demonstrating its practical application.

Summary: In this study, the effects of EGFR mutations on the susceptibility of different EGFR inhibitors were investigated using comprehensive molecular modeling and in vitro kinase inhibition assays. The results showed that three hot-spot residues were involved in the binding of osimertinib and afatinib to mutated EGFRs, enhancing their inhibitory activity. Furthermore, principal component analysis revealed that the molecular complexation of osimertinib against mutated EGFRs was in a closed conformation, leading to drug resistance.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.
