Mohamed Wanas is a technical leader for Nuclear Island Hydraulic Systems at GE Hitachi Nuclear Energy- a role that caps an interesting career path. His journey brought him to Canada, where a pivotal decision to pursue an MEng degree in the Department of Chemical Engineering helped lay the foundation for his current role in clean energy production.

Wanas completed his undergraduate degree in chemical engineering at the University of Alexandria in Egypt.  He worked on design, commissioning and normal operation phases in the oil and gas industry for eight years while he completed a Master of Applied Science (MASc) degree in Egypt.

Wanas had family in Canada and often travelled to Canada as a child and always hoped to return as an adult. In 2017 he returned with plans to pursue a PhD, however he had a strong desire to return to work in industry and began considering doing an MEng degree to return to work sooner.

Wanas initially considered applying to several Canadian universities; however, he was ultimately drawn to the University of Waterloo—not only because of its renowned engineering program, but also due to a connection he established with Chemical Engineering Graduate Studies Manager Judy Caron.

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.

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 Applied Carbon Nanotechnology Laboratory, 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.

Professor Milad Kamkar’s research group has developed the first all-graphene water-based ink for 3D printing via direct ink writing. The ink promises to unlock new possibilities for addressing environmental challenges, such as eliminating invisible electromagnetic pollution from our surroundings.

The eco-friendly graphene ink enables groundbreaking applications in advanced fields, including electromagnetic interference (EMI) shielding, electronics, and environmental protection while providing a scalable solution for next-generation 3D-printed technologies.

Graphene is a material renowned for its remarkable strength, electrical conductivity, and thermal properties. One of the challenges to the widespread utilization of graphene is that it is typically produced in powder form, which is difficult to handle and limits its full application potential.

Researchers overcame this barrier by precisely engineering the nano-scale surface chemistry of graphene nanosheets to make them dispersible in water, creating a room-temperature printable, eco-friendly ink.

Climate change is devastating the world’s coral reefs, and pollution from microplastics in the oceans further damages these delicate ecosystems. Researchers at the University of Waterloo have made a breakthrough in understanding how and why microplastics get trapped in coral reefs. The new study sheds light on the role of mucus naturally secreted by coral reefs in the accumulation of microplastic pollution.

Removal strategies must ensure that detaching microplastics does not worsen environmental impact by floating back into the ocean water. Designing artificial coral reefs to capture microplastics may be the most promising answer in the race to save the planet’s coral reefs.

Coral reefs are diverse and important ecosystems, providing habitat for 25 percent of all marine life. They provide food, shelter, breeding grounds, and nurseries for millions of species. Coral reefs play a role in filtering water and creating oxygen. They also protect shorelines from the impact of storms and floods.

Inspired by the movement of water striders cruising on the surface of water, a research group led by Professor Hamed Shahsavan have designed smart, soft microrobots whose movements can be controlled by light, offering exciting possibilities in environmental remediation and biomedical applications.

Imagine autonomous robots deployed to clean up microplastics in bodies of water. The research also has potential in biomedical applications. Microrobots could be guided inside the human body to conduct medical procedures.

“We’re moving toward smart swimming robots with more autonomous behaviour, by making them respond to external cues like light, or magnetic fields,” said Shahsavan, a professor in the Department of Chemical Engineering

Researchers at the University of Waterloo are taking a novel approach to tackle the critical issue of microplastic pollution in water systems. The research team is engineering bacteria that already exist in wastewater to break down Polyethylene terephthalate(PET).

Plastic waste in water systems is an urgent environmental concern. PET plastics degrade into microplastics that adversely impact the ecosystems of our lakes, rivers, and oceans.

Professor Marc Aucoin from the Department of Chemical Engineering and Professor Brian Ingalls from the Department of Applied Mathematics with PhD student Aaron Yip are developing a technique that enables wastewater bacteria to break the links between plastic molecules so PETs can be degraded.

Professors Aiping Yu and Michael Fowler have been named on the Highly Cited Researchers™ list from Clarivate. Researchers on that list have publications that rank in the top one percent of citations globally and are deemed influential in their respective fields.

Yu’s research expertise is in utilizing graphene for energy storage in Zinc-ion and Na-ion batteries to increase their energy and power density using 2D materials. As Director of the Applied Carbon Nanotechnology Laboratory, she is also focused on lithium battery recycling. Yu is also researching carbon dioxide conversion, using electrochemical cells to turn CO2 into small-chain chemicals like methane.

Researchers at the University of Waterloo can now make eco-friendly plastics using bacteria that feed on food scraps from your table. Unlike animals that store fat when they consume excess food, these bacteria store a biopolymer. Biopolymers are natural polymers produced by the cells of living organisms that are fully biodegradable. The biopolymer can be used in multiple applications, including single-use plastics.  

Utilizing food waste is beneficial to the environment as it typically generates methane and carbon dioxide when decomposing in landfills, contributing to greenhouse gases. 

Plastics produced using this new method have many potential applications. For example, in food packaging as a plastic film to cover meat.
