From principles to practices: Open Science at Europe’s universities. 2020-2021 EUA Open Science Survey results

This report presents the outcomes of the 2020-2021 EUA Open Science Survey and provides evidencebased recommendations for institutions, researchers, research funders and policymakers on the transition towards Open Science. The 2020-2021 EUA Open Science Survey focused on the level of development of Open Science in Europe‘s universities, addressing the role of Open Science in institutions’ strategic priorities and its implementation in institutional practices. In addition, the survey transversally addressed both the established (Open Access, research data) and emerging (e.g. citizen science, open education) fields of Open Science. This survey was open to all interested European higher academic institutions from October 2020 until January 2021, having gathered a total of 272 valid responses from institutions in 36 European countries. Most of the sample are comprehensive institutions (64%), followed by specialist (e.g. medical sciences, music, art schools) and technical universities, which both represent 13% of the sample. The full anonymised dataset of the survey is available in the Open Access repository Zenodo

Low modulus dry silicone-gel materials by photoinduced thiol-ene chemistry

The curing behavior of telechelic vinyl-functionalized poly(dimethylsiloxane) (PDMS) with poly(dimethylsiloxane-co-propylmercaptomethylsiloxane) using photoinitiated radical thiol-ene polyaddition was studied, by means of rheology, mechanical analysis of the cured elastomeric products, and high resolution magic angle spinning NMR (HR-MAS). Postpolymerization modification of a hydroxy-functionalized PDMS-derivative (OH-PDMS) yielded a telechelic thiol-functionalized PDMS-derivative, which was subsequently used as chain extender for the preparation of dry silicone-gel materials with elastic moduli between 30 and 500 kPa. The rate of thiol-ene polyaddition of the chain extender proved to be similar to that of the cross-linking process using multifunctional PDMS-based thiols. HR-MAS analysis of the loosely cross-linked thiol-ene PDMS networks and their fluoride-solubilized counterparts proved a highly efficient cross-linking with an optimal cure at 1:1 thiol to ene stoichiometric ratios. Using mechanical analysis, it was shown that the low molecular weight thiol-functionalized chain extender was efficiently incorporated in the PDMS polymer network
