Selective Nitrate Transmembrane Transport Through Adaptive Weak C─H Bonding Cyanostilbene Water Channels

Angewandte Chemie, EarlyView.
Here we demonstrate that weak HB CH donor cyanostilbenes promote water/ion transport through their ability to form less‐ordered transient water channels within the lipid bilayer with increased water permeability and NO3−/ Cl− selectivity. ABSTRACT Transmembrane water transport strongly depends on how dynamic, translocating water clusters are stabilized

Synthesis and Characterization of 1, 2, 3-Triazole Ligands and their Transition Metal Complexes [PDF]

, 2019
Click chemistry, an approach to synthesis using fast, versatile and high yielding reactions, has recently attracted attention as a simple way of preparing a wide scope of products. 1, 2, 3‐ triazoles can be prepared by Huisgen 1, 3‐ cycloaddition of azides and alkynes, where copper (I) as the catalyst dictates the formation of a 1, 4‐disubstituted ...

Generative and Experimental Validation of High Refractive Index Polymers via Domain Knowledge Approach with Small Data

Advanced Intelligent Discovery, EarlyView.
This research demonstrates that the combination of domain knowledge–based multiple regression, multi‐objective Bayesian optimization, and generative models is a suitable prediction tool for candidates of high refractive index polymers, even with the constraints in the model trained on limited data. The experimental validation can reproduce the proposed
