𝗗𝗘𝗙𝗘𝗡𝗦𝗘: We congratulate our teammate Diogo Sousa on successfully defending his master’s thesis. His work focused on approaches for the recovery and reuse of nickel from end-of-life high-temperature fuel/electrolysis cells. The research was conducted under the supervision of Dr Aleksey Yaremchenko and Dr Francielly Roussenq Cesconeto, with guidance from Dr Alexander Bamburov, within the framework of the project 𝗖𝗟𝗘𝗔𝗥𝗡𝗘𝗦𝗦 (ERA-MIN3/0005/2023, funded by FCT through the ERA-MIN3 European Network).

𝗘𝗩𝗘𝗡𝗧: This week, members of the Lab SSI&EC, Dr. Alexander Bamburov and Dr. Aleksey Yaremchenko, attended the 25th International Conference on Solid State Ionics (SSI-25), held in Singapore from 5 to 10 July. They presented recent results — two oral presentations and one poster — obtained within the framework of the ALCHEMHY Project EU (Grant Agreement No. 101177996, funded by the European Commission) and the CLEARNESS project (ERA-MIN3/0005/2023, funded by the FCT within the ERA-MIN3 European Network). The work carried out within the ALCHEMHY project focuses on the direct electrochemical synthesis of ammonia using protonic ceramic cells. The CLEARNESS project aims to recover and reuse components, particularly nickel, from end-of-life high-temperature fuel and electrolysis cells.

𝗘𝗩𝗘𝗡𝗧: Last week, Aleksey Yaremchenko and Mehdi Hedayati represented the Lab SSI&EC at the 8th International Conference “Prospects on Protonic Ceramic Cells” (PPCC 2026), organized by the International Society for Protonic Ceramic Conductors (ISPC²) and held in Nîmes, France, on 23-26 July 2026. Dr Aleksey Yaremchenko reported on an assessment of perovskite cathode materials for the direct electrochemical ammonia synthesis using protonic ceramic cells. Mehdi Hedayati shared results on the effects of a nickel oxide sintering aid on the processing and properties of a Ba(Ce,Zr,Y,Yb)O₃ solid electrolyte. Both studies were conducted in cooperation with partners from CIIAE - Iberian Centre for Research in Energy Storage within the framework of the ALCHEMHY project (Grant Agreement No. 101177996, funded by the European Commission).

𝗗𝗘𝗙𝗘𝗡𝗦𝗘: Diana Santos, a student of DEMaC/UA (Departamento de Engenharia de Materiais e Cerâmica - Universidade de Aveiro), successfully defended her industrial project entitled “Effect of the colloidal sol–gel synthesis route on the textural and electrochemical properties of CaTiO₃, SrTiO₃, and BaTiO₃.” The project was carried out at the Lab SSI&EC under the supervision of Dr. Francielly Roussenq Cesconeto and Dr. Parisa Amirkhizi. Diana’s objective was to assess the feasibility of industrial-scale production of titanate materials with enhanced performance for electronic and energy-conversion applications using a more environmentally friendly synthesis pathway than the traditional solid-state reaction route.

𝐍𝐄𝐖 𝐏𝐔𝐁𝐋𝐈𝐂𝐀𝐓𝐈𝐎𝐍: Our article, “Self-activating Ti3AlC2 MAX phase-Ni/Ni-Al composite electrodes for hydrogen evolution in alkaline media”, has recently been published in the International Journal of Hydrogen Energy. In this work, Ti3AlC2 MAX phase, a well-known precursor for MXenes, was explored as an active component embedded in metallic Ni and Ni-Al electrodes for alkaline hydrogen evolution. The proposed electrode architectures behave as dynamic, self-activating systems, with their performance improving as the surface evolves under cathodic polarisation in strongly alkaline conditions. This research was led by Daniela Lopes, with an important contribution from our former MSc student Américo Cruz, based on his thesis work, as well as from other Lab SSI&EC members Parisa Amirkhizi and Andrei Kovalevsky. The work was carried out in collaboration with Sergii Sergiienko from the Centre of Excellence for Advanced Materials Application, Slovak Academy of Sciences, Slovak Republic.
