Investigation of palladium catalysts in mesoporous silica support for CO oxidation and CO adsorption.

The oxidation of Carbon monoxide (CO) to Carbon dioxide (CO) is one of the most extensively investigated reactions in the field of heterogeneous catalysis, and it occurs via molecular rearrangements induced by catalytic metal atoms with oxygen intermediates. CO oxidation and CO capture are instrumental processes in the reduction of green-house gas emissions, both of which are used in low-temperature CO oxidation in the catalytic converters of vehicles. CO oxidation and CO adsorption at different temperatures are evaluated for palladium-supported silica aerogel (Pd/SiO).

Silica and carbon decorated silica nanosheet impact on primary human immune cells.

Silica nanosheets (SiO NS) are considered to be a promising material in clinical practice for diagnosis and therapy applications. However, an appropriate surface functionalization is essential to guarantee high biocompatibility and molecule loading ability. Although SiO NS are chemically stable, its effects on immune systems are still being explored.
