The performances of polybenzimidazole (PBI) and polysulfone (PSF) membranes for recovering water from reverse osmosis (RO) reject of brackish water through forward osmosis (FO) were assessed and compared. Non-functionalised multi-walled carbon nanotubes (MWCNT) were added to the membrane casting solutions, with concentrations ranging from 0 to 3 wt%. The experiment was conducted for eight samples using RO reject of brackish water as the feed solution (FS) and 2 M analytical grade MgCl as the draw solution (DS).

- Humanity is facing a significant challenge with the COVID-19 pandemic, caused by the SARS-CoV-2 virus, leading scientists to explore transmission mechanisms for better mitigation strategies.
- Researchers are examining the potential of graphene nanomaterials, which exhibit antimicrobial and antiviral properties, to help reduce the transmission of the virus, especially through protective equipment like masks and gloves.
- Graphene-based biosensors could provide rapid and accurate detection of the virus, aiding in the development of effective diagnostic tools for monitoring COVID-19 and other airborne viruses.
Energy storage technologies have gained considerable momentum in the recent years owing to the rising tide of renewables. The deployment of energy storage is a trend set to continue into 2018 and beyond. In the near future, compressed air energy storage (CAES) will serve as an integral component of several energy intensive sectors.
