KAUST researchers have developed an ultrathin polymer-based membrane for water desalination with high water flux and salt rejection. The membrane utilizes two-dimensional porous carbonaceous materials with subnanometer-sized molecular transport channels. The membrane outperformed existing desalination systems using carbon nanotubes and graphene in forward and reverse osmosis. Why it matters: This innovation offers a promising alternative for efficient and cost-effective desalination, addressing critical water scarcity challenges in the region and beyond.
KAUST researchers have developed a new solar distillation device that prevents salt accumulation by using a centimeter-scale plastic cube containing glass fiber membranes and carbon nanotubes. The design incorporates vertically oriented membranes with hydrophilic microchannels to transport seawater to the top solar layer for distillation. This elevated design doubles the freshwater production rate compared to existing salt-rejection solar stills. Why it matters: This innovation improves the efficiency and longevity of solar-powered desalination, offering a sustainable solution for water purification in emergency situations and remote areas.
KAUST has acquired a BM Pro plasma-enhanced chemical vapor deposition (PE-CVD) reactor from AIXTRON for wafer-scale deposition of graphene and carbon nanotubes. The reactor, capable of handling up to 4-inch substrates, will be used by Professor Pedro Da Costa's research team initially, before being opened up to other researchers at KAUST. AIXTRON's VP highlighted the system's uniformity, scalability, rapid heating, and plasma-based processing for growing graphene and nanotubes. Why it matters: This advanced tool enhances KAUST's research capabilities in carbon nanostructures, positioning the university as a leading center for materials science and nanotechnology research in the region.
