Interplay between lattice, orbital, and magnetic degrees of freedom in the chain-polymer Cu(II) breathing crystals [PDF]

, 2013
The chain-polymer Cu(II) breathing crystals C21H19CuF12N4O6 were studied using the x-ray diffraction and ab initio band structure calculations. We show that the crystal structure modification at T=146 K, associated with the spin crossover transition ...

Selective Separation of the Rare Earth Elements Dysprosium and Neodymium via Tailoring Nanocellulose Chemical Structure

Advanced Functional Materials, EarlyView.
Dicarboxylate‐modified anionic hairy cellulose nanocrystals exhibit a high selectivity for dysprosium(III) over neodymium(III). This selectivity arises from disordered dicarboxylate cellulose “hairs” that enable cooperative ionic coordination, hydrogen bonding, and strain‐induced conformational shrinkage.

Tris(nitrato-κ2O,O′)bis[4,4,5,5-tetramethyl-2-(pyridin-2-yl-κN)imidazoline-1-oxyl 3-oxide-κO]holmium(III)

Acta Crystallographica Section E, 2012
In the title compound, [Ho(NO3)3(C12H16N3O2)2], the HoIII ion is ten-coordinated in a distorted bicapped square-antiprismatic environment by two N,O-bidentate nitronyl nitroxide radical ligands and three O,O′-bidentate nitrate anions.

Preparation and Characterization of Hyperbranched Polystyrene Nanocomposite Synthesized by Living Radical Polymerization and Solution Intercalation Method [PDF]

علوم و تکنولوژی پلیمر, 2013
A copolymer of styrene and methyl styrene was synthesized by nitroxide - mediated “living” free radical polymerization )NMP). N-Bromosuccinimide was used as a brominating agent to obtain a copolymer with bromine as its end group.

Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design

Advanced Materials Technologies, EarlyView.
This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...

Molecular S = 2 High-Spin, S = 0 Low-Spin and S = 0 ⇄ 2 Spin-Transition/-Crossover Nickel(II)-Bis(nitroxide) Coordination Compounds

Inorganics, 2021
Heterospin systems have a great advantage in frontier orbital engineering since they utilize a wide diversity of paramagnetic chromophores and almost infinite combinations and mutual geometries.

Anti‐Apoptotic and Neurite‐Protective Nanomedicine Augments Embryonic Stem Cells‐Derived Retinal Ganglion Cell Transplantation in Glaucoma Recovery

Advanced Science, EarlyView.
Lithium‐epigallocatechin gallate nanoparticles (Li‐EGCG NPs) are co‐transplanted with embryonic stem cell‐derived retinal ganglion cells (ESC‐RGCs) to enhance cell survival and therapeutic efficacy in an acute pathological glaucomatous injury model. This synergistic approach protects RGC cells, preserves retinal structure and improves visual function ...

Synthesis And Characterization Of (pyNO−)2GaCl: A Redox-Active Gallium Complex [PDF]

, 2018
We report the synthesis of a gallium complex incorporating redox-active pyridyl nitroxide ligands. The (pyNO−)2GaCl complex was prepared in 85% yield via a salt metathesis route and was characterized by 1H and 13C NMR spectroscopies, X-ray diffraction ...
