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 ...

Er rare-earth ion incorporation in sol-gel SnO2

Materials Research, 2003
Er-doped SnO2 thin films and xerogels are obtained by sol-gel technique. In order to understand the Er³+ rare-earth ion activity in SnO2 matrix, a characterization of Er incorporation is done through emission and excitation spectra of xerogels, besides ...

Nitric oxide-releasing S-nitrosothiol-modified xerogels

Biomaterials, 2009
The synthesis, material characterization, and in vitro biocompatibility of S-nitrosothiol (RSNO)-modified xerogels is described. Thiol-functionalized xerogel films were formed by hydrolysis and co-condensation of 3-mercaptopropyltrimethoxysilane (MPTMS) and methyltrimethoxysilane (MTMOS) sol-gel precursors at varying concentrations.

Facile Synthesis of Carbon-Based Inks to Develop Metal-Free ORR Electrocatalysts for Electro-Fenton Removal of Amoxicillin

Gels
The electro-Fenton process is based on the generation of hydroxyl radicals (OH•) from hydroxide peroxide (H2O2) generated in situ by an oxygen reduction reaction (ORR).

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
