Cadmium associates with oxalate in calcium oxalate crystals and competes with calcium for translocation to stems in the cadmium bioindicator Gomphrena claussenii
Paula Pongrac, Tania Serra, Hiram Castillo Michel, Katarina Vogel-Mikuš, Iztok Arčon, Mitja Klemen, Boštjan Jencic, Anja Kavčič, Mina T. Villafort Carvalho, Mark G. M. Aarts, 2018, original scientific article

Abstract: Cadmium (Cd) was shown to co-localise with calcium (Ca) in oxalate crystals in the stems and leaves of Cd tolerant Gomphrena claussenii, but Cd binding remained unresolved. Using synchrotron radiation X-ray absorption near edge spectroscopy we demonstrate that in oxalate crystals of hydroponically grown G. claussenii the vast majority of Cd is bound to oxygen ligands in oxalate crystals (488%; Cd–O–C coordination) and the remaining Cd is bound to sulphur ligands (Cd–S–C coordination). Cadmium binding to oxalate does not depend on the amount of Ca supplied or from which organs the crystals originate (stems and mature leaves). By contrast, roots contain no oxalate crystals and therein Cd is bound predominantly by S ligands. The potential to remove Cd by extraction of Cd-rich oxalate crystals from plant material should be tested in phytoextraction or phytomining strategies.

Mineral element composition in grain of awned and awnletted wheat (Triticum aestivum L.) cultivars tissue-specific iron speciation and phytate and non-phytate ligand ratio
Hiram Castillo Michel, Iztok Arčon, Paula Pongrac, Katarina Vogel-Mikuš, 2020, original scientific article

Abstract: In wheat (Triticum aestivum L.), the awns—the bristle-like structures extending from lemmas—are photosynthetically active. Compared to awned cultivars, awnletted cultivars produce more grains per unit area and per spike, resulting in significant reduction in grain size, but their mineral element composition remains unstudied. Nine awned and 11 awnletted cultivars were grown simultaneously in the field. With no difference in 1000-grain weight, a larger calcium and manganese—but smaller iron (Fe) concentrations—were found in whole grain of awned than in awnletted cultivars. Micro X-ray absorption near edge structure analysis of different tissues of frozen-hydrated grain cross-sections revealed that differences in total Fe concentration were not accompanied by differences in Fe speciation (64% of Fe existed as ferric and 36% as ferrous species) or Fe ligands (53% were phytate and 47% were non-phytate ligands). In contrast, there was a distinct tissue-specificity with pericarp containing the largest proportion (86%) of ferric species and nucellar projection (49%) the smallest. Phytate ligand was predominant in aleurone, scutellum and embryo (72%, 70%, and 56%, respectively), while nucellar projection and pericarp contained only non-phytate ligands. Assuming Fe bioavailability depends on Fe ligands, we conclude that Fe bioavailability from wheat grain is tissue specific.

MAST PROFESSIONAL and PERSONAL DEVELOPMENT
Daniela Urem, Peter Purg, Tere Badia, Jernej Gerbec Čuček, Nayari Castillo Rutz, Sergi Bermudez di Badia, Simon Gmajner, professional monograph

Abstract: The MAST project Career Development Guide serves as a professional and personal development reference in the realm of Art, Science and Technology (AST). It aims to support a variety of needs for emerging practitioners and will also continue to be supported through Unicult learning events and opportunities through the project network partnerships.

Cross-sector Innovation Transfer
Andreja Lapuh Maležič, Jurij Krpan, Simon Gmajner, Peter Purg, Nayari Castillo Rutz, Sergi Bermudez di Badia, Dejan Kaligaro, Lea Mohorič, treatise, preliminary study, study

Abstract: The economic analysis showed that the MAST project is justified and represents added value for all users, the financial feasibility of carrying out the MAST project as such was confirmed. The set business model of the MAST project was proved to be sustainable in the long run, as the project from 2022 onwards shows considerable self-sustainability. Not only during its implementation but also at its finish the project may be estimated low-risk also for its possible future developments, as it clearly promotes an innovative idea and features a clear business model based on a professional team in capacity to face all the challenges and risks.

Sustainable impacts for studying and innovating through art, science and technology
Sergi Bermúdez, Daniela Urem, Nayarí Castillo-Rutz, Simon Gmajner, Peter Purg, Kornélia Kiss, 2020, treatise, preliminary study, study

Abstract: The MAST Sustainability Plan reflects the actions and strategies of the MAST project consortium that are to safeguard the longevity of the project’s positive impacts both on the level of participating institutions, the manifold stakeholder groups involved, and the broader network of (future) partnerships that may evolve and benefit from the project’s results.

Progressive pedagogies for innovation among art, science and technology
D. L. Sousa, F. Hedeer, Jurij V. Krpan, C. Csíkszentmihályi, Sergi Bermúdez i Badia, N. Castillo-Rutz, Peter Purg, Klemen Širok, 2022, original scientific article

Abstract: Even if aiming at technical innovation, an interdisciplinary curriculum can and should include social values. The Master Module in Art, Science and Technology project attempted to do so by developing the innovation catalyst profile, a graduate who critically reflects on the creation process by combining art thinking and design thinking. Within a pilot of the MAST module students from three universities responded to timely challenges such as ‘The Future of Work’ and ‘Solidarity,’ through which the project staff tested progressive pedagogical solutions like cross-disciplinary mentoring and situated knowledge sharing. Introducing European social values in both artistic and technical education, the article presents models, experiments and inspirations discussed against discursive analysis and course evaluation data. In order to support not only inclusive but also sustainable teaching and learning approaches, novel methods and tools may become daringly innovative as well as critical of both their pedagogical and the wider social setting.
