Imagine walking your dog in the middle of a blizzard or spending the day on a frigid ski hill and instead of wearing bulky layers, you have a winter coat that heats up autonomously!

New innovative cloth developed by a research group led by Professor Yuning Li requires no bulky batteries or manual controls, the warmth generated by the fabric comes entirely from solar energy, making it an environmentally friendly, self-sustaining solution for winter wear.

 Within 10 minutes of exposure to sunlight, the fabric’s temperature is able to rise by 30 degrees Celsius, keeping you cozy on a cold winter day.

Researchers have designed solar-powered smart fabric that not only warms up but also customizes its colour. A significant feature of this smart fabric fiber is its reversible colour-changing capability, which can monitor temperature fluctuations.

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.

A research group from the Department of Chemical Engineering, led by Professor Yverick Rangom, has made a breakthrough in lithium-ion battery design to enable extremely fast charging. With this novel technology, the batteries can charge from zero to 80 percent in just 15 minutes, a significant improvement over the current industry standard.

Batteries fabricated using this new strategy were shown to undergo 800 extreme fast charging cycles, a feat not possible with current EV batteries which limit charging times to prevent degradation.

The novel technology addresses major hurdles in the mass adoption of EVs: charging speed and cost.

In 2023, Professors William Anderson and Marc Aucoin supervised preliminary research on concussion biomarkers found in bodily fluids, particularly saliva.

Exploring concussion biomarker research

Initially, Shazia Tanvir, a research associate of Anderson’s, began exploring research on concussion biomarkers. She was later introduced to Andrew Cordssen-David, who was a Master of Business, Entrepreneurship and Technology student at the Conrad School of Entrepreneurship and Business at the time.

Cordssen-David was also a former student-athlete who played for the varsity men’s hockey team at the University of Waterloo and had experienced his share of concussions. Recognizing the potential impact of a saliva-based concussion test, Cordssen-David and Tanvir got to work, committing themselves to developing a new concept for a saliva-based concussion screening tool.

A new study by researchers at the University of Waterloo has uncovered a crucial mechanism in the evolution of regulatory systems in E. coli that could have far-reaching applications in cancer therapy and biomanufacturing for products such as insulin or mRNA vaccines.

The critical insight arose when the research team examined a regulatory mechanism near the tail end of a protein called PykF

“A helpful analogy to understand this mechanism is the speedometer in a car. When you're driving through a town, where there are dangers to avoid, you need to know how fast you're going, so the speedometer is important. But, if you're on an open stretch of road with no risks, you can throw the speedometer out the window and put the pedal to the metal,” said Dr. Christian Euler from the Department of Chemical Engineering. “The research opens up the potential to one day put a new stoplight on the road to limit growth rate.”

Professor Christian Euler leads a Canadian research team that aims to valorize waste materials such as plastics, CO2 emissions, methane and other gases, and agricultural residues, converting them into valuable commodities and chemicals. The goal is to devise technologies that provide economic incentives for waste recycling, making sustainability a driver of profit rather than a cost burden for industry.

The research group received funding from the Natural Sciences and Engineering Research Council of Canada (NSERC) and the Social Sciences and Humanities Research Council (SSHRC) as part of the National Science Foundation Global Centers initiative. University of Waterloo Researchers are part of the Center for Innovative Recycling and Circular Economy (CIRCLE).  

As the planet faces the ongoing effects of climate change and the accumulation of pollution in every ecosystem it’s clear that the pace of human development is unsustainable. CIRCLE seeks to address these challenges through a multidisciplinary global collaboration.

Professor Edward Rhodes was a professor in the Department of Chemical Engineering from 1964 to 1986. Rhodes was part of the Transport Phenomena Group and conducted research in multiphase flow and boiling heat transfer. Rhodes made significant contributions as chair of the department for 11 years, starting in 1976.

He was a kind and gifted administrator. His life and work influenced many students and young faculty members.

Rhodes’ career accomplishments also included his roles as Dean of Engineering at the University of Calgary, President of the Technical University of Nova Scotia and Vice President at Dalhousie University. He also served as Vice President of Technology for an international petrochemical company.

Rhodes was also known for his artistic side. He loved music and singing, often studying music on his lunch breaks!

He is remembered fondly by many former students, staff and faculty members.

Chemical Engineering Professor Alex Penlidis remembers Dr. Rhodes:

“Ted Rhodes was the department chair when I joined the Department of Chemical Engineering at Waterloo in 1986. He was first and foremost a kind person and a very astute and flexible administrator. He was an exemplary chair, as he was a good researcher and teacher, kind to students and colleagues alike, and a great administrator, who was interested in resolving issues and situations quickly and effectively."

Professors Michael Tam and Yuning Li have designed a solar-powered desalination device capable of utilizing over 93% of solar energy to produce fresh water from the sea via a thermal evaporation process.

This rate is five times higher than that of current technologies, making it a highly efficient solar-driven desalination system. With a production capacity of approximately 20 litres of fresh water per square meter per day, this device offers a sustainable solution to global freshwater scarcity.

Desalination of water is critical for many coastal nations to produce water for consumption and agricultural activities. Rapid population growth and increasing global water consumption by industry contribute to water scarcity.
