In December, Professor Dongmei Feng published an article entitled “More Flow Upstream and Less Flow Downstream: The Changing Form and Function of Global Rivers,” in the journal Science. This groundbreaking work, also featured on CNN, revealed surprising and concerning trends in the world’s rivers. Feng reported that nearly 3 million rivers worldwide are undergoing rapid changes, with potentially severe consequences for drinking water supplies, agriculture, and flood risks.
Using a combination of satellite data and computer modeling, Feng’s group analyzed the flow of water through every river on Earth, tracking daily changes over the past 35 years. Their findings show that nearly half of the world’s largest downstream rivers (44%) have experienced annual declines in water flow. The study attributes these changes to human activities and the fossil fuel-driven climate crisis, which are altering rainfall patterns and accelerating snowmelt. Reduced flow in downstream rivers means less freshwater for drinking, irrigation, and livestock, while also increasing the risk of flooding in some areas.
Description automatically generatedRecently, Dr. Feng received a $1 million NASA grant to further her research. Leveraging data from the new Surface Water and Ocean Topography (SWOT) satellite, her team will investigate greenhouse gas exchanges between rivers and the atmosphere. This work will focus on quantifying global river discharge and the exchange of carbon dioxide (CO₂) and methane (CH₄) between rivers and the atmosphere, advancing our understanding of how rivers influence the global carbon cycle.
The Department of Chemical and Environmental Engineering is proud to announce that Professor Panagiotis Smirniotis has been awarded the 2024 David F. Ollis Award for his lifetime contributions to the field of photocatalysis.

They were honored at a university reception held at the Digital Futures Building in January 2025.
Work in Dr. Greg Harris’ lab on nerve repair has the potential to transform recovery outcomes for millions of individuals affected by traumatic injuries. By targeting the complex challenges of nerve regeneration, his work aims to restore function and improve the quality of life for patients recovering from severe injuries. Current nerve regeneration and repair practices often rely on autografts, where nerves are taken from another part of the patient’s body, or engineered nerve guidance conduits, which serve as bioartificial alternatives. While effective, these methods have limitations. Harris and his team are advancing the field with a novel nerve guidance conduit that provides electrical, chemical, and physical cues to guide growing cells and nerves. “In making a multiplexed biomaterial, we’re able to mimic development and provide a path to grow and reinnervate damaged nerve tissue,” Harris explained. Though the science behind this approach is complex, its potential impact is clear: it could enable near-complete recovery for individuals suffering from debilitating nerve damage, offering them a chance to regain function and improve their quality of life.
Power plants and transportation are responsible for about 53% of all carbon dioxide emissions. The remaining emissions are generated by industry, commercial and residential buildings, agriculture and other human activities. The system Dr. Joo-Youp Lee developed in his lab uses electricity to separate carbon dioxide. But he is advancing his system by using hot water instead of electricity or steam in the desorption step, making it 50% more energy efficient than other carbon-capture systems. Air is passed through a special adsorbent material that Lee’s team designed to capture carbon dioxide. The developed system has been shown to remove carbon dioxide from the air at concentrations of approximately 420 ppm. And with his process, called direct air capture, it can be deployed virtually anywhere as opposed to conventional carbon capturing systems which are deployed predominantly at the source.

Professors Soryong Ryan Chae and Vadim Guliants were awarded funding for their proposal, “Highly Selective Recovery of High Value-Added Materials from Electrical and Electronic Wastes for Energy Storage.” The project addresses the growing issue of electrical and electronic waste (e-waste), which has surged due to the increasing global use of batteries in portable electronics, electric vehicles, and renewable energy systems. Recycling e-waste not only conserves valuable materials such as gold, silver, copper, and rare earth elements but also reduces the need for mining, decreases environmental pollution, and mitigates public health risks.
Last fall of 2024, the Federal Emergency Management Agency (FEMA) awarded a team from the CEAS, DAAP and COM with a $1.5 million grant. This 3-year funding is for a project to create a prototype of “cooled” firefighter`s garment. Multiple studies show that one of the main reasons for the firefighter`s fatalities is accumulation of metabolic heat inside the gear which dramatically increases the core body temperature and causes a heart attack. The multidisciplinary team involved in this project proposed advanced technology, particularly a lightweight and fire-resistant, wearable cooling unit that will be attached outside the garment and will enable cooling of the firefighter`s body. The prototype in development will be tested by firefighters in a live-burn scenario and further improved based on the feedback received.
The funded project is led by CEAS with PI and co-PI Profs. Mark Schulz and Vesselin Shanov. Dr. Shanov and his postdoctoral fellow Dr. Qichen Fang, along with the graduate student Ben Kraus are in charge of designing, creating and testing of a 3D printed cooling unit that meets the requirements of light weight, flame resistance, and strength. They are also employing infrared thermal monitoring to prove the cooling efficiency of the created prototype. The industrial partner for this project is Lion Apparel Inc., which is one of the largest manufacturers of fire-protection personal equipment in the country.
