Nanostructured Palladium-Doped Silica Membrane Layer Synthesis for Hydrogen Separation: Effect of Activated Sublayers [PDF]

open access: yesHydrogen, Fuel Cell & Energy Storage, 2019
Palladium doped silica membranes were synthesized by the sol-gel method using two different procedures. The first palladium-doped silica membrane (M1) was synthesized with a coating of four layers of silica-palladium sol.

Automated photo-aligned liquid crystal elastomer film fabrication with a low-tech, home-built robotic workstation

open access: yesScientific Reports, 2022
Laboratory procedures are often considered so unique that automating them is not economically justified – time and resources invested in designing, building and calibrating the machines are unlikely to pay off.

NanoStructured Sonogels [PDF]

open access: yesKey Engineering Materials, 2008
Acoustic cavitation effects in sol-gel liquid processing permits to obtain nanostructured materials, with size-dependent properties. The so-called “hot spots” produce very high temperatures and pressures which act as nanoreactors. Ultrasounds force the dissolution and the reaction stars.
