Using spray-dried lactose monohydrate in wet granulation method for a low-dose oral formulation of a paliperidone derivative
Abstract Content uniformity (CU) is a crucial evaluation factor, especially for low-dose oral formulations. Spray-dried monohydrate lactose is generally recommended for direct compression/dry granulation, but we observed that it showed advantages in ...

Correlation between structural rearrangement of hydrotalcite-type materials and CO2 sorption processes under pre-combustion decarbonisation conditions
Abstract Alkali-promoted hydrotalcite-based materials have showed CO2 sorption capacity up to 1.6 mmol⋅g−1 when CO2 separation is carried out at relatively high temperature (300–500 °C) and high partial pressure of steam and CO2, conditions that are ...
