Reviews published during the past two decades in Advances in Heterocyclic Chemistry have covered the various aspects of using these correlations in the heterocyclic series. The problems discussed in these reviews and monographs can be roughly divided into three groups: (1) the effects of annular ...
APPLICATION OF THE THEORY OF DIFFUSION-CONTROLLED REACTIONS TO KINETIC SALT EFFECTS OF THE HYDRATED ELECTRON. A generalised model for the application of statistical reaction rate theory to ion-molecule association reactions has been outlined. The model is based on ... S Logan 被引量: 5发表: 1968...
Quantum Hall effect in a CVD-grown oxide The authors demonstrate quantum Hall effect in semiconducting layered oxide Bi2O2Se. Its unique low mass among the oxides of 0.14 me and pronounced layered structure makes Bi2O2Se highly susceptible to the quantum confinement effects. Oleksandr Zheliuk ,...
