Selective strontium adsorption using synthesized sodium titanate in aqueous solution [PDF]

RSC Advances, 2022
Amorphous sodium titanates were synthesized using a mid-temperature sol–gel method for evaluation as selective adsorbents of strontium in the presence of cesium or metal cations (Al3+, Mg2+, Ca2+, and Mn2+) from aqueous solution.

Isotope tuning of the superconducting dome of strontium titanate [PDF]

Physical Review Research, 2021
Doped strontium titanate SrTiO3 (STO) is one of the most dilute superconductors known today. The fact that superconductivity occurs at very low carrier concentrations is one of the two reasons that the pairing mechanism is not yet understood, the other ...
