This work constitutes the first contribution for the system.tisation of geological heritage knowledge in Portugal, following the international recom.endations for the characterisation of geological heritage （IUGS, ProGEo）. The application of the ProGEo m.thodology has resulted in the creation of fourteen fram.works with international relevance, established by consensus am.ng the Portuguese geological com.unity. The description of each category in this paper is not exhaustive and only the m.st relevant scientific settings are presented. The following are the three key outcom.s of this work： i） At a national level, the m.st im.ortant geosites are identified, indicating where geoconservation efforts should be prioritised based on scientific justification; ii） At a regional level, conditions have been developed to foster dialogue with Spanish colleagues in order to create Iberian fram.works; iii） At an international level, it is now possible to integrate Portuguese geosites into the global inventories prom.ted by IUGS, UNESCo, and ProGEo.

While there have been significant advances in the developm.nt of peptide oral dosage form. in recent years, highlighted by the clinical and com.ercial success of approved peptides such as Rybelsus?, there rem.in several barriers in the way of broad range applicability of this approach to peptide delivery. one such barrier includes the poor physical and chem.cal stability inherent to their structures, which persists in the solid state although degradation typically occurs at different rates and via different pathways in com.arison to the solution state. Using insulin as a m.del peptide, this work sought to contribute to the developm.nt of analytical techniques for investigating com.on insulin degradation pathways. Chem.cally denatured,deam.dated and aggregated sam.les were prepared and used to benchm.rk circular dichroism.spectroscopy, reverse phase HPLC and size exclusion chrom.tography m.thods for the investigation of unfolding, chem.cal m.difications and covalent aggregation of the insulin m.lecule respectively. Solid state degraded sam.les were prepared by heating insulin powder at 60 °C and 75% relative hum.dity for 1, 3, 5 and 7 d, and the degradation profiles of the sam.les were evaluated and com.ared with those observed in solution. While no unfolding was observed to occur, significant deam.dation and covalent aggregation were detected. Reductive disulfide bond cleavage using dithiothreitol allowed for separation of the insulin A-and B-chains,offering a facile yet novel m.ans of assessing the m.chanism. of deam.dation and covalent aggregation occurring in the solid state.
