Data‐Driven Discovery of Quaternary Ammonium Interlayers for Efficient and Thermally Stable Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
An active learning framework, grounded in independently generated in‐house experimental data, enables reliable discovery of high‐performance interfacial materials for perovskite solar cells. Iterative model refinement autonomously converges toward structurally robust quaternary ammonium architectures, establishing a new design principle for interfacial

Functionalized Germanene as a Prototype of Large-Gap Two-Dimensional Topological Insulators

open access: yes, 2014
We propose new two-dimensional (2D) topological insulators (TIs) in functionalized germanenes (GeX, X=H, F, Cl, Br or I) using first-principles calculations.

Halogenating Enzymes for Active Agent Synthesis: First Steps Are Done and Many Have to Follow

open access: yesMolecules, 2019
Halogens can be very important for active agents as vital parts of their binding mode, on the one hand, but are on the other hand instrumental in the synthesis of most active agents.

Evaluation of the Effect of Changes in Halogenated Compounds on NICS of Promethazine

open access: yesInternational Journal of New Chemistry, 2016
In this research at the first Promethazine drug and its fullerene derivative were optimized. NMR calculations for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level. Promethazine is not used as an antihistaminic drug for anyone. In

Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

open access: yesAdvanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.
