Diblock copolymers composed of a polystyrene first block and a PEG-fluoroalkyl chain-modified polystyrene second block were synthesized by controlled atom transfer radical polymerization (ATRP), starting from the same polystyrene macroinitiator. The wettability of the polymer film surfaces was investigated by
The isotope (79)Se may be of great concern with regard to the safe disposal of nuclear wastes in deep geological repositories due to its long half-life and potential mobility in the geosphere. The Se mobility is controlled by the oxidation
Nanocrystalline FeS and FeSe compounds were prepared by solvothermal decomposition of a precursor complex [Fe(3)(μ(3)-O)(μ(2)-O(2)CCH(2)Cl)(6)(H(2)O)(3)]NO(3)·H(2)O in the presence of thiourea and sodium selenite, respectively. The as-obtained products were characterized by X-ray diffraction analysis (XRD), field emission scanning electron microscopy (FESEM)
