A liquid membrane containing diethylene glycol monobutyl ether (2) shows specificity for K ion in transport while diethylene glycol dibutyl ether (1) was selective for Na over K . As an extractant, ligand 2 exhibited pronounced extraction selectivity for K over Na in comparison with ligand 1

Heterogeneous Ziegler-Natta and homogeneous metallocene catalysts exhibit greatly different active sitenature in olefin polymerization. In our previous study, it was reported that MgCl2-supported titanocenecatalysts can generate both Ziegler-Natta-type and metallocene-type active sites according to the type of activators.The dual active site nature of the supported titanocene catalysts was furt...

Protein–ligand docking is the major workhorse in computeraided structure-based lead finding and optimization. Predicted protein–ligand complex configurations are used for studying protein–ligand interactions, estimating binding affinities, and as a final filter step in virtual screening. Early methods on protein–ligand docking treated either both proteins and ligands as rigid molecules or allow...

Abstract Background Nanoparticulate drug delivery systems have attracted significant attention in the field of cancer nanotechnology. This study determines the effect of folate-based Fe2O3 nanoparticles. This study aimed to decorate nanoparticles with folate (FA), a molecular ligand for ‘active’ targeting of cancerous cells and the application of modified-nanoparticles in cancer treatment. ...

phosphoryl containing ligand tri-n-octylphosphine oxide (topo) in dichloromethane has been used as an extracting agent for tetravalent thorium and trivalent europium ions from their 1 m sodium nitrates. the equilibrium data reveal that both ions are extracted as the complexes at 1:3 metal/ligand ratio. the values of conditional extraction equilibrium constant (kex) show the superior extractive ...

hyper-igm syndromes are characterized by profound reduction of serum igg, iga, and ige levels with normal or increased concentrations of serum igm. cd40 ligand deficiency is x-linked form of the disease, which results in a lack of immunoglobulin class switching from igm to igg in b cells. in addition to the recurrent infections, a number of patients suffer from neutropenia. there are some evide...

In article number 2300486, Jae-Wook Kang, Jeong-Hwan Lee, and co-workers employ a short-chain fluoroaromatic ligand, 4-fluoro-phenethylammonium bromide, to fine-tune the refractive index (n) horizontal dipole ratio values (ΘH) of FAPbBr3 nanocrystal film for light outcoupling efficiency enhancement. This work demonstrates that performance perovskite light-emitting diodes can be greatly enhanced...

Recently an iterative method was proposed to enhance the accuracy and efficiency of ligand-protein binding affinity prediction through linear interaction energy (LIE) theory. For ligand binding to flexible Cytochrome P450s (CYPs), this method was shown to decrease the root-mean-square error and standard deviation of error prediction by combining interaction energies of simulations starting from...
