Boron Nitride Nanotubes for Curcumin Delivery as an Anticancer Drug: A DFT Investigation

open access: yesApplied Sciences, 2022
The electrical properties and characteristics of the armchair boron nitride nanotube (BNNT) that interacts with the curcumin molecule as an anticancer drug were studied using ab initio calculations based on density functional theory (DFT). In this study,

Electrostatic considerations affecting the calculated HOMO–LUMO gap in protein molecules [PDF]

open access: yesJournal of Physics: Condensed Matter, 2013
A detailed study of energy differences between the highest occupied and lowest unoccupied molecular orbitals (HOMO-LUMO gaps) in protein systems and water clusters is presented. Recent work questioning the applicability of Kohn-Sham density-functional theory to proteins and large water clusters (E. Rudberg, J. Phys.: Condens. Mat. 2012, 24, 072202) has

Visualization and Comprehension of Electronic and Topographic Contrasts on Cooperatively Switched Diarylethene-Bridged Ditopic Ligand

open access: yesNanomaterials, 2022
Diarylethene is a prototypical molecular switch that can be reversibly photoisomerized between its open and closed forms. Ligands bpy-DAE-bpy, consisting of a phenyl-diarylethene-phenyl (DAE) central core and bipyridine (bpy) terminal substituents, are ...

Ion–solvent chemistry in lithium battery electrolytes: From mono-solvent to multi-solvent complexes

open access: yesFundamental Research, 2021
The building of safe and high energy-density lithium batteries is strongly dependent on the electrochemical performance of working electrolytes, in which ion–solvent interactions play a vital role. Herein, the ion–solvent chemistry is developed from mono-

Quantification of the Properties of Organic Molecules Using Core‐Loss Spectra as Neural Network Descriptors

open access: yesAdvanced Intelligent Systems, 2022
Artificial neural networks are applied to quantify the properties of organic molecules by introducing a new descriptor, a core‐loss spectrum, which is typically observed experimentally using electron or X‐ray spectroscopy.
