The 2025 Capstone projects were ambitious and innovative! Aiming to solve problems, running the gamut from converting plastic waste into hydrogen to creating a modular water treatment plant for Six Nations of the Grand River.

This graduating class pushed themselves to their limits, persevering through their first two years, which took place during the pandemic, and finishing their undergraduate degrees with innovation and tenacity.

The excitement was palpable at the Capstone Symposium as fourth-year students explained their projects to instructors, industrial partners, parents and eventgoers.

This year, there were six winning Capstone Projects in the Department of Chemical Engineering:

A research group led by Chemical Engineering Professor Milad Kamkar has developed a method to make it possible to have stable liquid droplets filled with different nanomaterials in another liquid. ��

��This breakthrough research has created completely new categories of “programmable" droplet-based soft materials containing a range of nanomaterials. These droplets can be dried and turned into aerogel beads (highly porous materials) that can be deployed in many applications, such as carbon capture and wastewater treatment.��

��In complex environments, like wastewater streams with multiple contaminants, the aerogel beads can be layered or mixed to target specific pollutants.����

“Each bead can absorb a specific type of pollution,” says Kamkar. “Making the material not just multifunctional, but strategically programmable.”��

David Liñán Romero has won the Chemical Engineering Medal for Proficiency in Research Park and Veva Reilly Medal. The award recognizes skill in solving a research problem and efficiency in finding solutions. The award consists of a silver medal and a cash award.

"Winning this award makes me feel gratitude towards those who have encouraged and supported my research and academic development—not only my advisor and colleagues, but also my family and friends,”says Liñán Romero. "My PhD research was in numerical optimization, so I feel this award also recognizes the relevance of computational tools in aiding chemical engineering to shape a more efficient and sustainable future.”

Liñán Romero was a PhD student in the Department of Chemical Engineering supervised by��Professor Luis Ricardez-Sandoval. He completed his doctoral studies in September 2024.

Liñán Romero’s main takeaways from studying with Ricardez-Sandoval were the importance of critical thinking and reasoning, as well as effective oral and written communication.

Professor Michael Tam has been named the 2025 recipient of the R.S. Jane Memorial Award by the Canadian Society of Chemical Engineering (CSChE). The award is presented to a person who has made exceptional achievements in the field of chemical engineering or chemistry.

“I am deeply honoured to receive this award, which reflects the hard work and contributions of the many talented students and researchers who have been part of my group since I began my academic journey in 1992,” Tam says.

Tam, a University Research Chair, is regarded as a pioneer and international leader in the fields of polymer colloids, surfactant-polymer interactions, nanomaterials, nanocellulose applications, and functional material science.

His research advances the development of sustainable nanomaterials for engineering applications in sectors such as cosmetics, personal & home care, agriculture, environmental remediation, and more.

In May, the Canadian Academy of Engineering (CAE) announced that Professor Aiping Yu has been elected as a Fellow.

CAE fellows are nominated and elected by their peers in recognition of their outstanding achievements and lifelong contributions to the field of Engineering.

“I’m honoured to join the esteemed Fellowship,” Yu said. “I’m excited and grateful to have been elected as a Fellow by the Canadian Academy of Engineering.”

Yu is a University Research Chair and is widely recognized for her disruptive research. Yu’s current research focuses on developing nanomaterials for energy storage, such as Na-ion, Zn-ion and Li-ion batteries, as well as battery recycling.

As the director of the , Yu is engineering graphene and other 2D materials to increase the power density and performance of batteries.

Yu has expertise in using nanomaterials such as nanotubes for the design of high-energy storage supercapacitors.

MASc student, CT Murphy’s start-up CELLECT is a finalist in the Odlum Brown Forum Pitch, a Canadian program for women entrepreneurs. Murphy’s partner and COO, Ibukun Elebute presented at the event and secured $44K in winnings for CELLECT.

The product is being designed by Murphy with the guidance of her supervisor, Professor Marc Aucoin. They are developing a menstrual pad infused with nanomaterials that will be able to collect bacterial and cervical cells. The pad would then be sent to a lab for processing.

What if researchers could understand how cells grow, adapt and behave using the same tools engineers use to design circuits?

A new tutorial bridges the gap between biology and engineering to unlock novel insights and inspire innovation in biotechnology, health, and environmental science.

Life itself can be considered a technology that has evolved over billions of years. The researchers propose that cellular processes and microorganisms that play critical roles in everything from disease response to digestion function in ways similar to engineered systems.

Professors Christian Euler, Matthew Scott and PhD student Mohammed Zim developed the tutorial based on a synthesis of significant, well-established research.

“You can have very interesting technical, almost like engineering-driven understandings of living systems, and those living systems can teach you something about engineering as well,” Euler says.

Winning a pitch competition is never easy, but it becomes even more challenging when there is no prototype or product ready for market. Despite these obstacles, Capstone Group 4 defied the odds and won $12,000 to advance their project!

The project, called Direct-Li, won the Norman Esch Entrepreneurship Award for Capstone Design. The group proposed a more efficient and eco-friendly process for lithium extraction.

Through engineering innovation, Group 4 developed a two-stage process called direct lithium extraction (DLE). Group members Rachel Kumara, Sophie Campbell, Maeve Seto and Louise Tayzon utilized nanofiltration and ion pump separation to extract 90 per cent more lithium per litre of water in half the time compared to��industry standards.

“We were delighted that we were successful in conveying our idea in a way that made the judges see value in something that we do not actually have, a solid prototype. Our ideas are based on simulations and models. We were shocked to win! We were just happy to be there and to be challenging ourselves, especially since we were the only all-women group in the competition!”

Professor Valerie Ward��is part of a new global coalition to revolutionize vaccine production with disruptive health technology. The technology is designed to enable local vaccine production, reducing production time from nine days to just one day. A breakthrough that has the potential to save millions of lives and significantly lower the cost of vaccine production.

A research coalition led by the Centre for Process Innovation (CPI) received $2.8 million from the Coalition of Epidemic Preparedness Innovation (CEPI) to fund technology development to combat epidemics and pandemics. The aim is to make small transportable units to manufacture vaccines, making vaccines more accessible and better able to deal with local outbreaks.

Ward is working with researchers and industry partners in Brazil, the UK, and Canada to aid the world in responding more swiftly and equitably to future epidemics and pandemics.��

The grant focuses on developing technology to meet two specific goals. The first is rapid production of vaccines. The second is to decentralize manufacturing so it can be produced at different sites in smaller batches.

Researchers in the Department of Chemical Engineering have developed a new method for engineering bacteria that can be leveraged to improve biomedical applications such as drug delivery, cancer therapy, anti-inflammatory treatments, and vaccine development.

The international research group, led by Professor Yilan Liu, developed a process that enables bacteria to secrete bacterial membrane vesicles (BMVs). BMVs are nanosized bubble-shaped structures naturally released by bacteria. They have significant potential as tools for the development of a variety of therapeutics. ��

Currently, the adoption of BMVs has been hindered by low production yields under natural conditions. The technique established by Liu resulted in a 140-fold increase in the secretion of BMVs.

"This advancement in bacterial engineering has the potential to be a transformative platform for next-generation vaccines, therapeutics, and nutrient delivery," says Liu. "This new process could profoundly impact global health by making biomedical treatments more efficient, accessible, and affordable."
