The JUN Group (Environmental Nanochemistry Laboratory, ENCL)
A Recent Picture of the Environmental NanoChemistry Lab Members at Shaw Park (June 28, 2019).

The Jun group is exploring the environmental impacts of human activities through improved understanding of the fate and transport of contaminants and nanoparticles. In particular, we aim to improve our understanding of environmental impacts of climate change. We study biogeological cycling in complex environmental systems from nanoscale to macroscale, with a view to conserving and restoring sound water environments.

Based on our strong scientific understanding of nanoscale interfacial chemistry and solid nucleation, we seek innovation for sustainable water. We develop new treatment techniques and catalysts for purifying drinking water and remediating contaminated water and soil, benefiting water reuse, managed aquifer recharge, and membrane processes. In addition, the ENCL investigates biomineralization and bio-inspired chemistry for novel materials development.

To address challenges in energy-water nexus, our group research involves a more comprehensive investigations of energy-related subsurface operation systems for sustainability, including geologic carbon dioxide sequestration and conventional and unconventional oil and gas recovery, hydrothermal energy, and nuclear waste disposal.
