Hydrophilic magnetite nanoparticles in the size range 30-10nm are easily and rapidly prepared under ultrasonic irradiation of Fe(OH)(2) in di- and tri-ethylene glycol/water solution with volume ratio varying between 7:3 and 3:7. Structural (XRD) and morphological (SEM) characterization reveal good
Because various non-parallel G-quadruplexes of human telomeric sequences in K+ solution can be converted to a parallel G-quadruplex by adding polyethylene glycol (PEG) as a co-solvent, we have taken advantage of this property of PEG to study the covalent attachment

In situ Co K-edge quick-EXAFS (QEXAFS) coupled with temperature-programmed oxidation as well as ex situ XAFS was applied to investigating the mechanism for enhancing the dispersion of Co(3)O(4) nanoparticles in a calcined Co/SiO(2) Fischer-Tropsch synthesis catalyst prepared by adding triethylene

A novel water-soluble NHC-Pd polymer with triethylene glycol legs was developed as a water soluble and highly recyclable catalyst that shows high catalytic activity in the Suzuki-Miyaura coupling of aryl chlorides in high yields in water at room temperature.
