Last fall, the US #DOE wrote an article about the 1st place winners for #outreach at the #Marine_Energy and Hydropower Collegiate Competitions, the former being our Purdue team with K-12 water wheel competitions, education kits, and more! energy.gov/eere/water/art…

Our paper in Desalination explores how membrane properties, burst pressure, & system optimization impact efficiency & water cost in integrated #Forward_Osmosis & osmotically assisted #Reverse_Osmosis systems. doi.org/10.1016/j.desa…

AWARDS OF EXCELLENCE: Congratulations to the Purdue Mechanical Engineering faculty chosen to receive 2025 Awards of Excellence from the College of Engineering: 🧑‍🏫David Warsinger: Early Career Teaching 💻Ilias Bilionis: Online Education 🧪Chi Hwan Lee: Research engineering.purdue.edu/Engr/People/Aw…

🎓Congratulations to our newly promoted Purdue Mechanical Engineering faculty: To Full Professor: Andres Arrieta, Christopher Goldenstein, Nina Mahmoudian To Associate Professor: Tian Li, Davin Piercey, David Warsinger Tenured Associate Professor: Shubhra Bansal, Yan Gu purdue.edu/newsroom/2025/…

I was honored to receive the Faculty Excellence Award for Early Career Teaching, which Purdue Engineering gives to one untenured prof. each year, along with a $4k prize! They even played a nice video from my students and colleagues at the awards ceremony! engineering.purdue.edu/Engr/People/Aw…

It's been an eventful couple of months! We had a baby, and I got tenure and a few awards; Best Early Career Teacher in Purdue Engineering, ACS PMSE Early Investigator, Journal of Membrane Science's Early Career Editorial Board, and the Showalter Foundation Early Career Grant!

Congratulations to #ISF faculty affiliates David Warsinger and Jose Garcia Bravo on receiving funding from the Office of Naval Research! Purdue Mechanical Engineering Purdue Polytechnic

One of our Lab’s PhD student, Md Ashiqur Rahman, is one of the winners of the 2025 SURF Lab Mentor Award—for the second summer in a row! This summer, he mentored two undergraduate researchers on membrane fabrication for air dehumidification. #SURF2025 #PurdueEngineering

Our team developed the first membrane #distillation #desalination system that uses slippery liquid infused surfaces (#SLIPS)! We saw modest improvements in #heat_transfer coefficients, and large efficiency gains from decreased droplet departure diameter. doi.org/10.1038/s44172…

For advanced oxidation of photocatalytic nanoparticles, we showed that material composites (e.g. Au/TiO2) improve performance more by reducing electron-hole recombination, rather than surface plasmon resonance or particle self-electrophoresis. doi.org/10.3390/w17111…

I really enjoyed this conference in Korea! My colleagues are doing some really great science! Also, it was great meeting up with others who trained at Menachem Elimelech (bottom right image)

Purdue announces patents awarded to faculty each month, and we had 3 awarded in September! The most of any Purdue faculty (one other had 2). stories.prf.org/september-edit…

Our team published a paper looking at whether pressure retarded osmosis could make #seawater Batch #Reverse_Osmosis more efficient, finding it could do so and achieve better (but still challenging) costs than conventional PRO doi.org/10.1016/j.rene…

Two of our lab members transitioned to faculty roles this Fall. PhD Student Sultan Alnajdi is starting at Kuwait University (The top ranked program in the country) and visiting scholar Manvi Yadav has started as a lecturer at Purdue Fort Wayne.

We are glad to have our team, Renaissance Water, led by Harmony Desalting, qualified for the XPrize for our Batch RO technology!

We coauthored a study on #supercritical water oxidation, which can separate salts, break down hydrocarbons, and even produce energy from them. The technique may be more cost effective than conventional alternatives for many highly saline produced waters. doi.org/10.1016/j.desa…

We introduce "temporally-multistaged" batch counterflow #reverse_osmosis, which drastically reduces capital costs of ultra-high salinity #reverse osmosis by using the same hardware for each stage, with holding tanks of varied salinity. doi.org/10.1016/j.desa…

The dynamic nature of batch #reverse_osmosis processes create much more need for optimization. We introduce #trajectory_optimization to temporally multi-staged batch reverse osmosis, to determine intermediate salinities and optimize energy and water flux. doi.org/10.1016/j.desa…

By directly coupling a hydraulic #wind_turbine with #reverse_osmosis, we can reduce capital costs, reduce energy losses, and take advantage of higher durability to operate in higher winds, resulting in better technoeconomics than uncoupled RO and wind. doi.org/10.1016/j.desa…
