Quick and robust analytical methods are of vital necessity in medicine and biology, making the synthesis of the electroactive substrates for the sensing of medically relevant chemicals a promising area of material science. Rare earth cuprates, mostly famous for high-temperature superconductivity, continue to exhibit encouraging electroactivity toward surface selective oxidation of biologically active compounds. Samarium cuprate reported in this paper showed developed surface with unique porous morphology and good conductivity – a set of prerequisites for sensing material. Further studies confirmed excellent samarium cuprate-based carbon paste electrode sensitivity of enalapril maleate and helped to develop an analytical method with selectivity and stability applicable for wider use.

I has been synthesized superconducting materials of the Nd1Ba2Cu3O7, Nd3Ba5Cu8O18 and Y3Ba5Cu8O18 phases. The study was conducted to determine whether the data from the phase Y1Ba2Cu3O7 can be used as a base to identify superconducting material of the Nd3Ba5Cu8O18 phase. Synthesis was done by solid state reaction method with initial mixing in HNO3 solution mixture with Y2O3, Nd2O3, BaCO3, and CuO, with the ratio adjusted to the stoichiometry calculation. Samples in the form of pellets with a diameter of 1.5 cm were sintered at 950 oC for 24 hours in an atmospheric environment. The FTIR measurements have been carried out with a standard KBr. The theoretical calculation spectra and vibration mode data from YBa2Cu3O7-d can be used to identify Nd1Ba2Cu3O7, Nd3Ba5Cu8O18 dan Y3Ba5Cu8O18, with peak absorption in the range of wave numbers that are almost the same, namely 400-450 cm-1, which is the four oxygen atoms O(2,3) mode, 426-439 cm-1 is the in-phase mode of oxygen atom O(2,3), and the vibrational mode of peaks O(4) is observed at 488 cm-1.
