On really stoichiometric LiCoO2

The Li NMR T1 relaxation time is shown to be a very severe criterion for determining the stoichiometry of LiCoO2. When Co3O4 containing minimum impurity level of paramagnetic ions such as Fe or Ni is used as starting material (together with Li2CO3), a T1 value as long as 18 s is obtained but this requires a rather long thermal treatment for complete elimination of excess Li. Such highly stoichi...

Stoichiometric models and flux analysis

There have been recent advances in metabolic flux analysis. In particular, the marriage of traditional flux balancing with NMR isotopomer distribution analysis holds great promise for the detailed quantification of physiology. Nevertheless, flux analysis yields only static snap-shots of metabolism. To robustly predict the time evolution of metabolic networks, dynamic mathematical models, especi...

Formation of Stoichiometric CsFn Compounds

Alkali halides MX, have been viewed as typical ionic compounds, characterized by 1:1 ratio necessary for charge balance between M(+) and X(-). It was proposed that group I elements like Cs can be oxidized further under high pressure. Here we perform a comprehensive study for the CsF-F system at pressures up to 100 GPa, and find extremely versatile chemistry. A series of CsFn (n ≥ 1) compounds a...
