We describe a novel strategy to increase the unit-time-productivity of flow synthesis by using hierarchical bimodal porous silica gel (HBPSG) supported palladium column reactors. Because HBPSG has a significantly large surface area, the column reacto

We report a new synthetic strategy for melamine-formaldehyde (MF) monoliths with controlled hierarchical porosity toward metal-ion scavengers. The obtained MF monoliths possessed micro-, meso- and macroporosity, which allowed efficient adsorption per

A practical and efficient method for scavenging palladium leached into the reaction mixture using thiol-modified dual-pore silica beads has been developed. Reducing the level of metal contamination, especially palladium, in pharmaceutical and bioacti
