We have a new group photo for the 2026 Warsinger Lab! See our website for the full list of members: warsinger.com/teammembers I wonder if any other Purdue labs have as many undergrads as we do...

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.desal.2025…

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.desal.2025…

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.desal.2023…

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.desal.2025…

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.

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.renene.202…

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-ed…

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/w17111708

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/s44172-025-0…
