Summary: This study found that the hydrogen storage capacity of purified MWCNTs was significantly enhanced by incorporating Ti catalyst, with longer exposure of Ti to the MWCNTs leading to further improvement in hydrogen storage capacity. The interfacial diffusion of hydrogen and the presence of a higher amount of Ti on the MWCNTs were identified as key factors contributing to the enhanced hydrogen uptake.

Summary: Reverse osmosis is the most widely used strategy in membrane technology. This study focuses on improving the performance of thin-film membranes by modifying the surface characteristics of support layers. Different membranes were fabricated using interfacial polymerization, with varying concentrations of multiwalled carbon nanotubes and ethanol. The results showed that the membrane with a selective layer of PA-EtOH 30% exhibited the best salt rejection, while the membrane with PA-MWCNTs 0.15% had the lowest salt rejection due to its hydrophobic nature.
