DFT-guided charge-state engineering of gold clusters for levodopa recognition: fundamental principles for drug delivery applications

Obijiofor O., Новиков А. С., New Journal of Chemistry 2026 Vol. 50 No. 23 P. 9749–9768

Rational design of gold-based nanocarriers for neurotherapeutics requires atomic-scale understanding of drug-material interactions. Density functional theory calculations were performed to investigate levodopa (L-DOPA) adsorption on small gold clusters (Au2–Au4) with cationic, neutral, and anionic charges, with additional validation on a larger Au10 cluster using multiple low-energy isomers. Binding free energies (ΔGbind), charge transfer, and electronic descriptors ...

Electrostatically gated dissipation control in two-dimensional nanoelectromechanical resonators via strain-amplitude antagonism for record 928% Q tunability

Jiang Q., Fang J., Chen J. и др., Science China Information Sciences 2026 Vol. 69 No. 6 Article 162402

Resonators based on nanoelectromechanical systems (NEMS) using two-dimensional (2D) materials with high-quality factors and excellent electrical control are critical for tunable coherent phonon dynamics, resonant sensors and wireless communications. However, their performance is fundamentally limited by the lack of a unified framework governing energy dissipation mechanisms and their electrical tunability. Here, we synergistically modulate both ...

Исследованы инжекционные полупроводниковые микролазеры с кольцевым резонатором радиусом 15 мкм с несимметричным расположением внутреннего отверстия резонатора. Показано, что асимметрия обеспечивает формирование в диаграмме направленности двух лепестков излучения, разориентированных на 50° относительно оси смещения внутреннего отверстия. Измеренная добротность резонаторов сопоставима с добротностью дисковых резонаторов и находится на уровне ∼ 10^6. ...

The scientific community has shown great interest in the selectivity of anion-exchange membranes (AEMs), particularly regarding their ability to monovalent-ions selective transport. In this work, we have studied the selectivity of an original anion-exchange membrane and a layer-by-layer (LbL) surface-modified membrane in the electrodialysis (ED) desalination of sodium chloride and sodium sulfate mixture in a ...
