Our research group will be introduced at the I. BME Competence Fair organised by BME on 17. June 2022

The 1st BME Competence Fair, organised by BME on 17. June 2022 is a first of its kind program for showcasing research and creativity, disseminating results and facilitating multidisciplinary cooperation.

The aim of the event is to facilitate the meeting of like-minded experts from all over Europe for future research collaborations and European grant applications.

The hybrid (online and in-person) event will provide various opportunities for building connections: research pitches, thematic breakout room discussions and networking sessions. The program will also feature panel discussions on trending topics of the European Research Area.

The networking will be facilitated by an innovative mobile application (Whova) for setting up smart profiles, initiating 1:1 or group discussions around topics of interest and organizing meetups.

There will be 4 pitching sessions, each of them introducing 2 research groups of BME during 2*3 minutes.

Our research group will be presented by Dr Viktória Feigl in Pitching Session 2.

Further information about the event, schedule and registration could be reached at: https://innovacio.bme.hu/innovacios-nap/

The over 4 years long SCALE project, funded by H2020-EU.3.5.3, was successfully completed on 31.05.2021

The SCALE project (Production of Scandium compounds and Scandium Aluminum alloys from European metallurgical by- products) funded by the EU Research and Innovation programme H2020-EU.3.5.3 was successfully completed on 31.05.2021.

The main achievements:

• An optimized, commercially viable, eco-friendly selective ion recovery (SIR) technology process for extracting scandium from bauxite residues was patented and demonstrated at pilot scale, imparting sustainability benefits to the environment.
• Al-Sc master alloys was produced at small industrial scale and used in production of Al-Mg-Sc alloys.
• Al-Sc 3D printing with SCALE alloy was demonstrated.
• Direct production of Al with ~ 2wt% Sc by electrolysis from a cryolite melt with Al2O3and Sc2O3 as feed material was demonstrated, obtaining current efficiencies in the range of 85-90%. Besides, dross residues from Al-Sc master alloy production were successfully used as feed, i.e., as Al2O3 and Sc2O3 In this way, the dross material can be valorised by the developed innovative electrolysis process.
• Acid resistant nanofiltration process developed and tested at laboratory and pilot scale proved to be suitable for extraction of Sc from strongly acidic process wastewater  (acidic waste of TiO2 production).
