WebJul 8, 2024 · The gel–sol transition (Figure 2a(i)) and the dissolution of the microrods (Figure 2a(ii)) were both induced by heating. Next, a combination of physical and enzymatic crosslinking was used to generate microrods that did not exhibit gel–sol transition at elevated temperature (Figure S1a,b , Supporting Information), as a control study of the … WebTaking into account the millions of different thermosensitive organic, inorganic, and bio-organic substances that could be used in producing hybrids and composites, the potential of low-temperature sol–gel technology is immense. In fact, it is a ‘second wind’ for developing classical sol–gel technology, with its more than a hundred-year ... dwarf fortress stone types
