Influence of potassium doping on the structural, conduction mechanism, and dielectric properties of CaFe2O4

Mohamed Mounir Bouzayani, Manel Ben Abdessalem, Ibtihel Soudani, Abderrazek Oueslati and Abdelhedi Aydi

The frequency and temperature-related dielectric relaxation and electrical conduction mechanisms in potassium-doped CaFe2O4 oxide ceramic were investigated in this study throughout a temperature range of 313–673 K.

Ceria nanomaterials containing ytterbium: low and high concentration – luminescence analyzed in the near infrared region

Sitshengisiwe Chemura, Tim Schrumpf, Christina Günter and Michael U. Kumke

CeO2:Yb nanoparticles were characterized for their NIR luminescence at RT and at T = 4 K. The PARAFAC analysis yielded luminescence decay kinetics as well as the associated luminescence spectra for Yb3+ species in different local environments.

Preparation of barium sulfate chelating agent DTPA-5Na and molecular dynamics simulation of chelating mechanism

Chao Ma, Xin Liu, Cheng Wang, Shengtian Gao and Xiaoyi Huang

DTPA-5Na synthesized using specific chemicals. Its structure determined by infrared spectroscopy. It effectively removes BaSO4 scale through various methods. A model of DTPA-5Na and BaSO4 interaction was created using simulation software, where carboxylic groups play a significant role.
