Autor: Sonia García-Gómez, Javier Giménez, Ignasi Casas, Jordi Llorca, Joan De Pablo, Albert Martínez-Torrents, Frederic Clarens, Jakub Kokinda, Luis Iglesias, Daniel Serrano-Purroy
Publikováno v: Nuclear Engineering and Technology, Vol 56, Iss 1, Pp 34-41 (2024)
This work presents experimental data and modelling of the release of Mo from high-burnup spent nuclear fuel (63 MWd/kgU) at two different pH values, 8.4 and 13.2 in air. The release of Mo from SF to the solution is around two orders of magnitude high

Gd2O3 Doped UO2(s) Corrosion in the Presence of Silicate and Calcium under Alkaline Conditions
Autor: Sonia García-Gómez, Javier Giménez, Ignasi Casas, Jordi Llorca, Joan De Pablo
Publikováno v: Inorganics, Vol 11, Iss 12, p 469 (2023)
The anodic reactivity of UO2 and UO2 doped with Gd2O3 was investigated by electrochemical methods in slightly alkaline conditions in the presence of silicate and calcium. At the end of the experiments, the electrodes were analysed by X-ray photoelect

Publikováno v: Sensors, Vol 19, Iss 19, p 4249 (2019)
Screen-printed carbon nanofiber electrodes (SPCNFEs) represent an alternative with great acceptance due to their results, as well as their low impact on the environment. In order to improve their performance, in the present work they were modified wi

Publikováno v: PLoS ONE, Vol 4, Iss 3, p e4728 (2009)
BACKGROUND: The efficacy of oxaliplatin in cancer chemotherapy is limited by the development of drug resistance. MMP7 has been related to the loss of tumor cell response to cytotoxic agents although the exact mechanism is not fully understood. Moreov

Retention of cesium and strontium by uranophane, Ca(UO
Autor: Alexandra, Espriu-Gascon, Javier, Giménez, Ignasi, Casas, Joan, de Pablo
Publikováno v: Journal of hazardous materials. 353
This work determines the capacity of uranophane, one of the long-term uranyl secondary solid phases formed on the spent nuclear fuel (SNF), to retain radionuclides (cesium and strontium) released during the dissolution of the SNF. Sorption was fast i
