Investigation on the binding functions and selectivities of imprinting polymers with o-vanillin;

Study on complexes of rare earth with Schiff base from o-vanillin and p-toluidine;

Study on Inducing the Strain Producing Vanillin by UV-photoreactivation;

Study on Separation and Purification of Total Vanillin by Adsorbing Resin;

Advances in biosynthetic technology of vanillin;
