Direct air capture (DAC) is an emerging technology that can help limit the global temperature rises, as it has potential to contrast dispersed CO2 emissions coming from transport and heating cannot be captured with traditional CCS methods. Although recent improvements are bringing DAC closer commercial feasibility, obstacle its diffusion high regeneration energy required by most common liquid sorbents, Na or K hydroxides. To develop efficient more sustainable in this screening study, several...

Methylene blue (MB) can be employed as a photo-activatable antimicrobial drug in photodynamic therapy (PDT) due to its ability release oxygen free radicals upon photo-activation. However, poor penetrate bacterial cell walls and biofilms limits activity. To overcome these limitations, we propose some formulations of MB based on different cationic liposomes. The liposome-MB systems were characterized using dynamic light scattering (DLS), zeta potential analysis UV-visible spectroscopy. Their...
