Naphthalimide Derivatives as Film‐Based Fluorescent Sensors for Rapid Detection of Illicit Drugs

Advanced Sensor Research, EarlyView.
Four novel 1,8‐naphthalimide (NI) derivatives for the detection of illicit drugs with different substituents at the 4‐position are reported. Their contrasting fluorescence responses enables five illicit drugs to be distinguished from interferents with a mean classification accuracy of 81%.

Surface Elasticity Based Nonlocal Vibration Analysis of Bidirectional Functionally Graded Tapered Nanobeam

Advanced Theory and Simulations, EarlyView.
This work proposes a surface elasticity‐based nonlocal model for analyzing the vibrations of bi‐directionally graded tapered nanobeam. The results demonstrate that, in absence of surface effect, the increasing value of tapered parameter leads to stiffness‐hardening of the nanobeam. However, the consideration of surface effect changes this trend and the

Effect of Atomic Charges on C2H2/CO2/CH4 Separation Performances of Covalent‐Organic Framework Adsorbents

Advanced Theory and Simulations, EarlyView.
Three charge assignment approaches (one quantum chemistry method‐based, the other two machine‐learning (ML) model‐based) are employed to investigate acetylene separation performances of experimental covalent‐organic frameworks. Partial Atomic Charge Predicter for Porous Materials based on Graph Convolutional Neural Network (PACMAN) ML model‐based ...
