Tunable Color Center Photoluminescence in Boron Nitride Nanotubes Through Reductive Arylation
ChemPhotoChem, Volume 10, Issue 10, October 2026.Reductive arylation of boron nitride nanotubes introduces sp3 boron defects that act as luminescent color centers. The emission wavelength is tuned not only by defect density but also by the electronic properties of aryl substituents, providing a molecular defect‐engineering strategy for the development of nanoscale light sources based on chemistry for

Synthesis, IR and NMR spectral correlations in some symmetrical diimines
Bulletin of the Chemical Society of Ethiopia, 2014 A series of diimines have been synthesized by coupling of diamine with substituted benzaldehydes. The purities of these diimines were checked by their analytical and spectroscopic data. The spectral frequencies νCN (cm-1), NMR chemical shifts (δ, ppm) of

A Multi‐Scale Computational Framework for Anti‐Persister Tuberculosis Drug Discovery
Chemical Biology &Drug Design, Volume 108, Issue 4, October 2026.This review presents an integrated QSAR–scaffold design–docking–MD framework for discovering anti‐persister tuberculosis agents active in dormant granuloma‐like conditions. By targeting Mtb bioenergetics and prioritising dual NDH‐2/cytochrome bd oxidase inhibition, the workflow advances rational design of candidates with higher resistance barriers ...
