The redox properties of K17[Ln(As2W17O61)2](Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Tm or Yb) in solution were investigated using polarographic and cyclic volt
The synthesis of zeolite HXDM-Theta-1(HXDM = hexanediamine) from the reaction mixture HXDM-Al2O3-SiO2-HF-H2O is described. The formation of HXDM-Theta-1 is favo
The microstructure of selected specimens in the (Y,Ce)-TZP-Al2O3 composite systems was studied. The investigation techniques used in this work included X-ray di
The present paper covers an X-ray photoelectron spectroscopic (XPS) method proposed for identifying Bronsted and Lewis acidic sites in zeolites and estimating a
