[Recent advances in the application of high performance capillary electrophoresis for food safety].

In recent years, food safety incidents become a serious social problem. Foods are usually complex mixtures consisting of a large diversity of molecules. Analysis of foods is a topic that demands the development of rapid, robust, efficient, sensitive and cost-effective analytical methodologies.

Synthesis and electrochemical properties of chemically substituted LiMn2O4 prepared by a solution-based gel method.

Lithium manganese oxide, LiMn(2)O(4), and its substituted samples LiM(0.05)Mn(1.95)O(4) (M=Al, Co, and Zn) were first prepared by a cost-saving and effective new solution-based gel method using a mixture of acetate and ethanol as the chelating agent.

Enhancement of the electrochemical properties of LiMn2O4 through Al3+ and F- co-substitution.

The cathode-active materials LiMn2O4, LiAl0.1Mn1.9O4, and LiAl0.
