Nitric oxide conversion to nitrogen on the W3O6 cluster through the ammonia selective catalytic reduction reaction: a DFT study

Results in Chemistry
Nitric oxide (NO), a harmful byproduct of fossil fuel combustion, can be effectively removed via the Selective Catalytic Reduction (SCR) process using ammonia (NH3), producing N2 and H2O.

Simultaneous Determination and Quantification of NineNitrosamine Impurities in Semi-Solid Forms Using a GC–MS/MS Method

Separations
Many studies are being conducted on the detection of nitrosamine impurities in solid formulations. However, research on semi-solid formulations such as gels, ointments and creams is not common. In particular, excipients used to increase viscosity and add
