Journal of hazardous materials, 129(1-3), 260-265 (2005-10-21)
A homogeneous catalyst system made up of [Co(NH3)6]2+/I- has been put forward to catalyze the oxidation of concentrated ammonium sulfite. The experiments were performed in a packed column with sulfite concentrations above 2.5 mol l(-1), temperature range 20-65 degrees C
Hikoya Hayatsu et al.
Nucleic acids symposium series (2004), (51)(51), 47-48 (2007-11-22)
Methylation at position 5 of cytosine in DNA plays a major role in epigenetic gene control. The methylation analysis can be performed by bisulfite genomic sequencing. Conventional procedures in this analysis include a treatment of single stranded DNA with 3-5
