The solvation and redox behavior of mixed ligand copper(II) complexes of acetylacetonate and aromatic diimines in ionic liquids [PDF]

, 2014
The behavior of two cationic copper complexes of acetylacetonate and 2,2'-bipyridine or 1,10-phenanthroline, [Cu(acac)(bipy)]Cl (1) and [Cu(acac)(phen)]Cl (2), in organic solvents and ionic liquids, was studied by spectroscopic and electrochemical ...

Rice Husk Lignin to Vanillin: IonoSolv as a Way Forward for Value-Added Biomass Depolymerization

BioResources, 2023
The depolymerization of natural biomass-based lignin is a definitive challenge, as it involves the integral breakdown of complex and well-constructed natural structures. A sustainable method called ‘ionoSolv pretreatment’ employs ionic liquids in biomass

Sugar-Derived Ionic Liquids

CHIMIA, 2011
Ionic liquids (ILs) are special molten salts with melting points below 100 °C that are typically constituted of organic cations (imidazolium, pyridinium, sulfonium, phosphonium, etc.) and inorganic anions. Due to their ionic nature, they are endowed with high chemical and thermal stability, good solvent properties, and non-measurable vapor ...

Accelerating charging dynamics in sub-nanometer pores [PDF]

, 2013
Having smaller energy density than batteries, supercapacitors have exceptional power density and cyclability. Their energy density can be increased using ionic liquids and electrodes with sub-nanometer pores, but this tends to reduce their power density ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Characterization of 1,8-diazabicyclo(5.4.0)undec-7-ene-hydroxyl-based ionic liquid for CO2 capture

Royal Society Open Science
Six 1,8-diazabicyclo(5.4.0)undec-7-ene-based ionic liquids (ILs) linked with ethyl or propyl hydroxyl cations, coupled with thiocyanate, dicyanamide and bistriflimide anions, were synthesized through a two-step reaction: quaternization and ion exchange ...
