A low-cost, 3D-printed filter developed by researchers at Waterloo Engineering removes up to 90 per cent of harmful microplastics from water.

The efficiency of the customizable filter, created in a three-step process, makes it a promising, inexpensive device for both residential and commercial applications.

Coated seeds that hold moisture until it rains are one of several innovations Waterloo Engineering researchers have developed while working with government, academic and industry partners in the agricultural sector.

“The problems we face today are complex, and their solutions demand equally complex expertise,” said Dr. Christian Euler, a chemical engineering professor. “By collaborating across disciplines, we move toward addressing these problems and strengthening Ontario's food resilience.”

Researchers at Waterloo Engineering have designed a new electrode with potential impact on the way energy generated on wind and solar farms is stored in the future.

The electrode was inspired by shapes found in nature and took advantage of the design freedom of 3D printing to help optimize redox flow batteries as safer alternatives to the lithium-ion batteries now used in many energy-storage systems.

Researchers at Waterloo Engineering are using artificial intelligence (AI), data science and advanced mathematics to help save lives by predicting how fires behave in modern homes.

The new system tackles a growing challenge for fire researchers: modern furniture materials and increasingly airtight, energy-efficient homes can cause fires to behave differently than they did in the past. 

Researchers from the faculties of engineering and mathematics at the University of Waterloo are working on a joint project that could lead to a new cancer treatment involving the use of engineered bacteria to essentially eat tumours from the inside out.

Dr. Marc Aucoin, a professor of chemical engineering, and Dr. Brian Ingalls, a professor of applied mathematics, outlined their research and the history behind their promising approach in an article recently published by the website The Conversation Canada.

A lightweight material created by researchers at Waterloo Engineering could spare health-care workers from chronic pain by replacing the heavy lead now used in X-ray aprons to provide protection from radiation.

Made from a soft, silicone-based plastic mixed with nanoparticles of tungsten, the lead alternative reduces the weight of X-ray aprons by almost 90 per cent while still offering a similar level of protection.

A research team led by Waterloo Engineering students, including several undergraduates, has created a tissue-like hydrogel material for potential use for artificial muscles in robotics.

Hydrogels are soft, biocompatible materials with great promise for developing microrobots to perform non-invasive biomedical tasks within the human body, including the gastrointestinal and reproductive tracts.

Researchers at Waterloo Engineering used nanotechnology to develop a new formulation that is both greener and more effective than existing methods for applying pesticides to plants.

Their water-based solution reduces costly waste and environmental contamination by making pesticides stick to plant leaves better – even in wind and rain – minimizing splash and runoff.

Bacteria engineered to eat cancerous tumours from the inside out have been developed by Waterloo Engineering researchers in a promising new approach to treatment.

The interdisciplinary research team found two key solutions to use a bacterium called Clostridium sporogenes, which is commonly found in soil and can only grow in environments with absolutely no oxygen, to effectively consume cancer.

Researchers at Waterloo Engineering have created a green alternative to absorbent materials now used in personal hygiene products such as diapers, menstrual pads and tampons.

The new, natural hydrogel breaks down harmlessly in soil within three months, unlike existing synthetic materials that are expected to take centuries to degrade and greatly contribute to the waste in landfill sites.
