The Tc decreases with increasing R ion size as observed in (Pb,Cu)-1212 systems, which suggests that the R ion size dependence of Tc can be a common characteristic of Pb-based 1212 systems. The sample with R=Lu and y=0.35 exhibits Tc(onset)=70 K and Tc(zero)=63.8 K. 展开 ...

The theoretical basis of the temperature variation of collision rates is examined and it is shown that deexcitation rates are much less sensitive to electron temperatures than are the corresponding excitation rates. The results of this study have implications for the future development of metal-ion ...
Study of the base-catalysed oxidation of the anti-bacterial and anti-protozoal agent metronidazole by permanganate ion in alkaline medium The effects of added products and the dielectric constant and ionic strength of the reaction medium were investigated. The main products were identified by ... AA...
