Zeolites for efficient oil-water separation

07-Dec-2012: Scientists in China have used zeolite-coated mesh films for gravity-driven oil-water separation. The superhydrophilicity and underwater superoleophobicity of the zeolite’s surface allow the highly efficient separation of various oils. Unlike other oil-water separation membranes based on superhydrophilic and superoleophobic organic layers, the zeolite inorganic films are corrosion-resistant, which makes them ideal candidates for a range of applications such as an oil retention barrier in industrial outlet sewer pipes, oil fences for oil spill accidents and separation of domestic waste oil.

    MOF-polymer composite membranes to enhance proton conductivity in fuel cells

    Nafion (a perfluorosulfonic acid membrane) is widely used in fuel cells to conduct protons, but Nafion membranes are prone to rapid dehydration at low humidity, which results in a loss of conductivity. To overcome this problem, scientists in China have made a metal-organic framework (MOF) co ... more

    Graphene Rainbow

    Butterfly wings, rose petals and many other natural surfaces repell water strongly; they are superhydrophobic. Such surfaces have a hierarchical structure on the micrometer or nanometer scale. Their attractive properties and spectacular iridescent colors have triggered a group led by Hong-B ... more
