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 p/n heterojunction is the basic setup for light-electric conversion. It has been widely accepted that the ideal configuration for organic photovoltaics is formed by the joint of a pair of long-range continuous but nanometre-wide phases consisting of electron-donating (D)
Amit Vaish et al.

Soft-lithography-based techniques are widely used to fabricate microarrays. Here, the use of microcontact insertion printing is described, a soft-lithography method specifically developed for patterning at the dilute scales necessary for highly selective biorecognition.
