Darren obtained his PhD degree in Chemical Engineering from The University of New South Wales, Australia. He has research interests in the field of membrane water and wastewater treatment, water reclamation and heavy metals stabilization, particularly in applying physical and chemical principles for fundamental research. Recently he is heavily engaged in the study of novel membrane technologies for water and energy production including hybrid membrane bioreactor, membrane coagulation system and TiO2 based nano-structured/fiber/tube membrane. Externally, Darren holds visiting Professorship at Shandong University, PR China. He is a Chair for International Water Associate (IWA) Specialist Group on Chemical Industries and Associate Editor for Water Science and Technology.

US 2014/0305864 A1: An Inorganic Fibrous Membrane And A Method For Fabricating Thereof (2020)
Abstract: A method of fabricating an inorganic fibrous membrane, the method comprising the steps of: grafting sulfonated graphene oxide onto a scaffold of inorganic nanofibers to form a suspension of heterojunctions of the sulfonated graphene oxide and the scaffold; filtering the suspension through a support to obtain heterojunctions on the support; drying the heterojunctions on the support; and removing the support to obtain the inorganic fibrous membrane.

US2013/0098833A1: Method of Preparing a Nanocomposite Membrane and Nanocomposite Membranes Prepared Thereof (2020)
Abstract: The present invention relates to a method of preparing a nanocomposite membrane, comprising: (a) providing a nanocomposite solution comprising a polymer solution and nanomaterials; (b) subjecting the nanocomposite solution to a cold water bath to produce the nanocomposite membrane in a gel-like form; and (c) subjecting the gel nanocomposite membrane to a heat treatment to solidify the nanocomposite membrane, wherein the nanomaterials are dispersed within the polymer matrix of the nanocomposite membrane.

US 2010/264097 A1: Hollow Porous Microspheres (2013)
Abstract: The present invention refers to a hollow microsphere having a porous circumferential wall comprised of nanofilaments.
