Radiochemical reaction of DT/ T and CO under high pressure.

For both fuel cycle design and safety evolution of tritium (T) in fusion reactor, it is important to study irradiation-induced reactions between T and various molecular species produced from nuclear-fusion fuel cleanup systems. The radiochemical reactions between deuterium-tritium/tritium and carbon monoxide of different concentrations under 1.0 MPa were elucidated in this work.

Noble Metal-Free Oxygen Reduction Reaction Catalysts Derived from Prussian Blue Nanocrystals Dispersed in Polyaniline.

A highly efficient noble-metal-free catalyst for the oxygen reduction reaction (ORR) is derived from a composite of polyaniline (PANI) and Prussian blue analogue (PBA, Co3[Fe(CN)6]2) by pyrolysis. The composite consists of 2-5 nm PBA nanocrystals homogeneously dispersed in PANI. During the pyrolysis, the PBA nanocrystals serve as both the template for the pore formation and the precursor for the ORR active sites, which results in a nanoporous structure strongly coupled with the ORR active sites.
