“…The berkelium, californium, einsteinium, and fermium mass-yield curves peak at about mass numbers 249, 250, 252, and 254 5 respectively. These maxima correspond to effective transfers of H, 2 He, 4 Li, and 6 Be. The yields for the plutonium isotopes are highest at the highest energy, 272 to 288 MeV.…”

“…Because they both show registry with the (111) growth plane, they are each expected to have a C 3 axis. One possible explanation is that one trapping cage has local CCP symmetry whereas the other is HCP (see the discussion in the previous section on CC1 4 in krypton). Further study and thought are required to elaborate on the implications of these results.…”

“…Various clean-up steps of the tungsten, including washes of the organic phase with H 2 O 2 , HNO 3 , and H 2 O proved unsuccessful. Tungsten is easily back-extracted into NH 4 OH, but so are the contaminants. Further work is necessary to obtain pure tungsten samples.…”

“…Table 6.1 presents some examples of substances that we have synthesized with FOOF and the conditions required for the most convenient "ordinary" syntheses. Of particular significance is the production of volatile PuF 6 from a variety of plutonium materials (PuO 2 , incinerator ash, " " NajPrFj + HF SOF 4 " " 250°C, 90 atm BrFj C1F 5 >200°, «50 atm F 2 PuO 2 F 2 , and PuF 4 ). FOOF is the only substance capable of volatilizing plutonium at a significant rate below 250°C, and it is effective even at -78°C.…”

Low-Temperature Trapping of Intermediates in the Reaction of NO^• with O₂

2017

View full text Add to dashboard Cite

The autoxidation of NO was studied in glass-like matrices of 2-methylbutane at 110 K and in a 8:3 v/v mixture of 2,2-dimethylbutane and n-pentane (rigisolve) at 80-90 K, by letting gaseous NO diffuse into these solvents that were saturated with O. In 2-methyllbutane, we observed a red compound. However, in rigisolve at 85-90 K, a bright yellow color appears that turns red when the sample is warmed by 10-20 K. The new yellow compound is a precursor of the red one and also diamagnetic. The UV-vis spectrum of the yellow compound contains a band which resembles that present in ONOO. Because the red and yellow intermediates are not paramagnetic, we postulate that O═N-O-O is in close contact with NO, or with another O═N-O-O. Diffusion of gaseous O into rigisolve saturated with NO does not produce a color; however, a weak EPR signal (g = 2.010) is observed. This signal most likely indicates the presence of ONOO. These findings complement our earlier observation of a red color at low temperatures and the presence of ONOO in the gas phase (Galliker, B.; Kissner, R.; Nauser, T.; Koppenol, W. H. Chem. Eur. J. 2009, 15, 6161-6168), and they indicate that the termolecular autoxidation of nitrogen monoxide proceeds via the intermediate ONOO and not via NO.
