Reproducible Green Syntheses Using Hybrid Sol‐Gel Catalysts
Chemistry – A European Journal, Volume 30, Issue 50, September 5, 2024.Aiming to contribute to eradicate a certain naiveté common to many research chemists specializing in green chemistry and catalysis, this study illustrates through selected examples of reproducible green syntheses using hybrid sol‐gel catalysts from doctoral theses and research articles published between 2013 and early 2024, how said catalysts have been

Carbon Dots: A Review with Focus on Sustainability
Advanced Science, Volume 11, Issue 35, September 18, 2024.Carbon dots (CDs) are an emerging class of optical nanomaterials, which can deliver function on par with the incumbents, while being free from toxic metals and critical raw materials. In particular, CDs derived from plentiful biomass can become truly sustainable, provided that their synthesis and processing are environmentally friendly.

Strengthening of SLS Glasses by Hybrid Ormosil Coatings
Key Engineering Materials, 2004 Hybrid ormosil (organic-inorganic) solutions can be used to coat float glass samples in order to increase their strength. The ormosil solution in this present work contains silane, epoxy resin and hardener based on Al-alkoxide. The glass samples were indented at their center in order to create artificial flaws.

Advanced Materials, Volume 36, Issue 18, May 2, 2024.It has already been ≈90 years since the first development of aerogels, and many researchers have devoted tremendous efforts to enhance their mechanical properties, which is yet completely achieved. This review presents multiscale, multicompositional and multidimensional strategies, resulting from flexible synthesis techniques for 0D–1D, 0D–2D, 1D–2D ...
