Size Control of Carbon Xerogel Spheres as Key Factor Governing the H₂O₂ Selectivity in Metal-Free Bifunctional Electro-Fenton Catalysts for Tetracycline Degradation

Gels
Carbon xerogel spheres co-doped with nitrogen and eco-graphene were synthesized using a typical solvothermal method. The results indicate that the incorporation of eco-graphene enhances the electrochemical properties, such as the current density (JK) and

Aspirin loaded xerogels for buccal and oral GIT delivery for patients with dysphagia to target deep vein thrombosis

British Journal of Pharmacy, 2018
This study aimed to develop xerogels for delivery of aspirin via the oral (buccal mucosa and GIT) route in geriatric patients with dysphagia. Xerogels were prepared using low molecular weight chitosan (CS), carrageenan (CAR) and metolose (MET) in ...

Anchoring selenido-carbonyl ruthenium clusters to functionalised silica xerogels

Journal of the Brazilian Chemical Society, 2003
Silica Xerogels containing carbonyl Ru3Se2 nido clusters were prepared in three different ways. The simple dispersion of [Ru3(mu3-Se)2(CO)7(PPh 3)2] via sol gel process produces an inhomogeneous material; by contrast, homogeneous xerogels were obtained ...

New hybrid organochlorinated xerogels

, 2021
Hybrid silica xerogels (HSXG) combine the properties of organic and inorganic components in the same material, which makes them promising and versatile candidates for multiple applications. These materials can be easily prepared by the sol-gel process, which offers the possibility to obtain different morphologies.
