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

open access: yesAdvanced 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 ...

Low speed aerodynamic characteristics of an 0.075-scale F-15 airplane model at high angles of attack and sideslip [PDF]

open access: yes
An 0.075 scale model representative of the F-15 airplane was tested in the Ames 12 foot pressure wind tunnel at a Mach number of 0.16 to determine static longitudinal and lateral directional characteristics at spin attitudes for Reynolds numbers from 1 ...

Excitation Energy Transfer between Porphyrin Dyes on a Clay Surface: A Study Employing Multifidelity Machine Learning

open access: yesAdvanced Theory and Simulations, EarlyView.
Inspired by natural light‐harvesting systems, this study computationally investigates a synthetic antenna by arranging cationic free‐base porphyrin molecules on an anionic clay surface. Using a multiscale quantum mechanics/molecular mechanics (QM/MM) approach combined with a multifidelity machine learning method, excitation energies are predicted ...

Force and moment measurements on a 74 deg delta wing with an apex flap [PDF]

open access: yes
Results are presented of a subsonic experimental investigation of an apex flap concept on a 74 deg swept delta wing with trailing-edge flaps. The apex flap comprised approximately 6 percent of the wing area forward of a transverse hinge, allowing for ...

Effect of Anion Hydrophobicity on the Oxidation of Ferrocene‐Terminated Monolayers

open access: yesAdvanced Theory and Simulations, EarlyView.
Self‐assembled monolayers terminated with ferrocene moieties can be oxidized using an applied potential. At the oxidized layer, anions from the electrolyte can form a layer. Experiments show a relationship between the hydrophobicity of the anion species and the redox potential.
