The de Lannoy lab is focused on environmental separation processes, applications to real environmental systems, and the implications of these technologies. My lab primarily uses experimental techniques supported by modeling of mass transfer processes, electrochemical kinetics, and catalysis. We are currently engaged in 5 areas of research:

Environmental Electrochemistry and Advanced Oxidation:

  • Electrically responsive membranes
  • Catalytic and electro-catalytic degradation of contaminants
  • Recovery and reaction of waste into valuable by-products
  • Integrated electrochemical impedance spectroscopy (EIS) as environmental sensing technologies

Membrane Materials and Processes:

  • Metallic Membranes and metallic porous thin-films
  • Controlling and mitigating biofouling, organic fouling, colloidal fouling, and scaling
  • Membranes and their interactions within treatment trains (e.g. potable reuse, desalination)
  • Manufacturing and scale-up of nanocomposite membranes
  • Material advances in microfiltration (MF), ultrafiltration (UF), and reverse osmosis (RO) membranes

First Nations and their Water:

  • Co-creating solutions to the First Nations Water Crisis through mutual respect and collaboration
  • Re-imaging water and wastewater infrastructure in First Nations communities to better align with cultural values
  • Sensors for remote, continuous water quality monitoring in the field

Aerosol Filtration and Facemasks:

  • Particle and aerosol filtration
  • Aerosol dynamics and transport
  • Alternative materials to non-reusable polymer facemasks and respirators

Sorbents and Nanomaterials:

  • Carbon nanotube-, graphene-, and nanocellulose based nanocomposites
    organic-metallic nanocomposites for enhanced contaminant adsorption
  • Sustainable biomaterials as alternative activated carbons (ACs), porous carbons, and reusable sorbents
  • Catch and release sorbents
