The JUN Group (Environmental Nanochemistry Laboratory, ENCL)
A Recent Picture of the Environmental NanoChemistry Lab Members (June 29, 2022).

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.

March 29-April 4, 2019: Prof. Jun and Yaguang attended the American Chemical Society in Orlando. We had an ENCL reunion dinner with Prof. Jessica Ray, Dr. Qingyun Li, and Dr. Haesung Jung. It was so nice to see you all again!

March 25, 2019: Congratulations! Dr. Lijie Zhang (PhD in 2018) received the 2019 Chinese Government Award for Outstanding Self-financed Student Study Abroad. We are very proud of her and it is a well deserved recognition! Congratulations, Dr. Zhang!

March 22, 2019: Prof. Alan Stone at Johns Hopkins visited WUStL for our department seminar, and the ENCL met Prof. Stone.

March 22, 2019: Congratulations! Deoukchen was chosen to attend the 2019 ACS Summer School on Green Chemistry & Sustainable Energy, July 16-23, 2019, Colorado School of Mines, Golden, Colorado, and he will receive a full financial support from the American Chemical Society. The summer school explores scientific solutions to global sustainability challenges in green chemistry and sustainable energy.

March 8-11, 2019: Xuanhao, Deoukchen, Zhenwei, Yaguang, Albern, Dennis, and Eunyoung travelled to Argonne National Laboratory to conduct GISAXS experiments at Sector 12ID-B.

February 23, 2019: Hello, Future Woman Scientists and Engineers! We offered hands-on workshops to female high school students as a part of the 2019 Women in STEM event.

Enjoy reading an inspiring article in Scientific America entited "We Need More Women in the Energy Sector" by Katie Mehnert (Feb 26, 2019). She said "Diversity leads to innovation, and that’s what it will take to fight climate change"

February 22, 2019: Congratulations to Yaguang! Yaguang received the American Chemical Society’s geochemistry division student travel award for attending the Spring 2019 ACS National Meeting in Orlando, FL, March 31-April 4, 2019.

February 14, 2019: Congratulations! Our paper entitled "Effects of Sulfate on Biotite Interfacial Reactions under High Temperature and High CO2 Pressure" was accepted inPhysical Chemistry Chemical Physics. Our findings suggest that anions (sulfate, phosphate, phosphonate, acetate, and oxalate) affect water-biotite interfacial interactions to different extents and subsequently altered surface wettability under subsurface environments.

February 4, 2019: Congratulations to Xuanhao! Xuanhao has been selected as a winner of the 2018 Graduate Student Award in Environmental Chemistry in the Division of Environmental Chemistry of the American Chemical Society.

February 4, 2019: Our recent photothermal membrane work was introduced in National Academy of Engineering's Frontiers of Engineering website. "Using Bacteria to CLEAN Water"

January 31, 2019: Our school has a new name now "McKelvey School of Engineering".

January 30, 2019: Our recent photothermal membrane work was introduced through St. Louis Public Radio "WashU Engineers Use Bacteria And Nanotechnology To Purify Dirty Water"

January 23, 2019: Welcome aboard, Eunyoung and Dennis (Ping-I)! Dennis and Eunyoung formally joined our group for their doctoral study.

January 11, 2019: Congratulations! Our collaborative paper entitled "A Robust and Scalable Polydopamine/Bacterial Nanocellulose Hybrid Membrane for Efficient Wastewater Treatment " was accepted for publication in ACS Applied Nano Materials. This study reports a novel membrane comprised of polydopamine (PDA) particles and bacterial nanocellulose (BNC), which can efficiently remove a variety of metal ions (e.g., Pb and Cd) and organic dyes from contaminated water. Link to the paper

January 2, 2019: Congratulations! Our collaborative paper entitled "Photothermally-active Reduced Graphene Oxide/Bacterial Nanocellulose Composites as Biofouling-resistant Ultrafiltration Membranes" was chosen to be highlighted as the Cover Art of Environmental Science & Technology January 2, 2019. Link to the paper.

Using reduced graphene oxide and bacterial nanocellulose, in this study, we developed an innovative ultrafiltration membrane that harvests sunlight to kill microorganisms.
