There is a perception out there that Waterloo Engineering is a great place for a practical undergraduate education (I won’t argue with that), but when it comes to more theoretical graduate studies and research in Canada you should look to one of the other big names. I will argue with that, and of course present some data for analysis. Continue reading
One focus of my research group’s efforts over the past 10 years has been collaborative R&D with small and start-up companies. They often have some very interesting ideas and needs, but lack the facilities and technical team to do the work in-house. So this is a perfect opportunity for us to help them out with creating new businesses and for my students to get some “real-world” research experience with commercialization projects.
One major effort has been in the development of nanotechnology for rapid water quality testing, in particular for bacterial contamination. Traditional laboratory methods require 3 to 7 days to complete, which is a rather long time to wait if you’re concerned about your water quality. Through our collaborative R&D projects, we’ve developed a test method that can give an answer in a few minutes. This rapid feedback allows people to make informed decisions about what to do next, whether to treat the water further, or send samples to a lab for more extensive testing, etc.
One recent development is the creation of a more automated, smart-phone based system that’s suitable for regular consumer use. A prototype model is shown in the photograph. We’ve been testing the prototype devices with our nanotechnology-based reagent (which goes into the test tube), and doing validation and calibration work. Everything is looking good and everyone has been pleased with the results. It’s reliably and quickly detecting microbial contamination in our water samples, and there are some other water tests under development that will be able to use the same platform.
To get to the next stage, which is production of the first batch of devices for sale, the company has just launched a Kickstarter campaign. Have a look at their Kickstarter website to see much more information about the technology and where they are headed.
An interesting competition event showcasing environmental water quality innovations by student groups. Sponsored by the Water Institute at Waterloo, one of the research centres I belong to.
The AquaHacking 2017 semi-final competition unfolded last week at CIGI. By the end of the evening, five teams were chosen to move on to the final competition at Waterloo on September 13. It was a difficult decision for the five judges, as all 17 teams that competed offered innovative ideas that tackled the challenges and opportunities facing Lake Erie.

Recent advances in the fields of human-machine interaction and artificial intelligence (AI) have been so swift that even experts like Fakhri Karray shake their heads in amazement.
A tragic statistic tells us that of all the people admitted to hospitals for various reasons, about 10% will get sick from an infection picked up in the hospital, something called a Healthcare Acquired Infection (HAI) or nosocomial infection. Of these, about 5% will die from it, which corresponds to about 10,000 Canadian deaths per year. The additional costs of treating these infections add up to between $4 and $5 billion in Canada. The consequences are proportionately similar in other regions such as the U.S. and Europe. The increases in antibiotic resistance in bacteria are adding to the problem.
Hospital infection control has traditionally focused on hand-washing, isolation, and cleaning and disinfection protocols to minimize the spread of “germs”. However, there is a limit to how far these can go, since they rely on consistent human behaviour, which is naturally inconsistent. Therefore in recent years there has been more focus on “engineered” approaches to infection control. To this end, my research group and I have been working with the Coalition for Healthcare Acquired Infection Reduction (CHAIR) to help develop and test materials, processes and devices that may help in the fight against HAIs.
One project we finished tested the effects of an automated ultraviolet light (UV) disinfection device placed in patients’ bathrooms to control the background bacterial contamination between uses. The paper can be read on this website. The data indicated that it was possible to dramatically lower bacterial contamination levels with this device, which was nice to see.
In other work, we’ve been collaborating with Aereus Technologies to develop new antimicrobial materials and coatings for use on hospital “high-touch” surfaces and equipment. This doesn’t eliminate the need for surface cleaning and disinfection, but it helps to kill the germs that land there between cleanings and thus reduce the chance for spread of infections.
In other more basic research, we’ve been collaborating with various other professors here at Waterloo to identify novel antimicrobial materials or detection methods for contaminants. For example, with Prof. Michael Tam’s group we’ve published a couple of studies on antibacterial cellulose materials (abstracts are available here and here). We recently published another paper on detection of bacterial contamination in water using an interesting combination of enzymology and nanotechnology.
If you’re wondering what this has to do with Chemical Engineering, well basically this is chemical engineering. Working with production and characterization of materials, interactions of materials, life science and biochemistry…those are all part of chemical engineering education and possible career paths.
Hopefully over the next few years this HAI problem will begin to see some progress and we can continue to contribute to the solutions.

A research team at the University of Waterloo played a key role in the development of a highly autonomous vehicle that Renesas Electronics America unveiled this week at the Consumer Electronics Show (CES) in Las Vegas.
Using sensors and powerful computers, the car is capable of detecting and responding to other vehicles, stop signs and traffic lights to provide a safer driving experience. For example, vehicle-to-infrastructure communications allow the vehicle to detect in advance when a traffic light will change. Continue reading
Exciting news about the start of construction for our new building, as well as support for automotive research and education, design, and entrepreneurship.
The University of Waterloo breaks ground today on Engineering 7, an $88-million building that will feature some of the best engineering research and teaching facilities in the world.The ground-breaking event will take place on Thursday November 12, at 1:30 pm at Engineering 5 on the University’s east campus.The new Engineering 7 (E7) facility will feature an additive manufacturing—or 3D printing—laboratory and an indoor flight arena for testing autonomous and robotic vehicles.It will also accommodate growth from Waterloo’s new biomedical engineering program and the expansion of the Faculty of Engineering’s highly popular mechatronics engineering program. It will house the Faculty’s new teaching innovation, the multidisciplinary Engineering Ideas Clinic™, where undergraduate students will integrate classroom theory with hands-on learning as they design, build, test and refine ideas.Part of the funding for E7 will come from the Educating the Engineer of the Future campaign, a $70-million fundraising effort that will help the Faculty of Engineering achieve its goal to become a world-class engineering school.Earlier this week, GM Canada announced $1 million in funding to support the Educating the Engineer of the Future campaign. This support will fund a Research Chair in advanced materials while also sponsoring Waterloo Engineering’s Capstone Design projects involving software development, which is key to GM Canada’s work on “the connected car.”E7 will also become the new home for the Conrad Business, Entrepreneurship and Technology Centre. It will have dedicated study and social spaces for students, lecture halls and entrepreneurial support areas, along with areas for student teams to prototype their Capstone Design projects.
I’ve always intended to write about some research work, but never find the time. However, here is a link to a write-up by one of our staff writers. And a picture of me with a couple of my graduate level (i.e. Masters) researchers.
Waterloo Engineering’s chemical engineering research gives manufacturer a global advantage.
Here is an interesting story about some of our Nanotechnology Engineering students, who used their creativity and expertise in materials science to develop a business idea for a compound that warns you when you need to re-apply sunscreen. They won a $15,000 prize to help carry on building their start-up company.
There was another story a while ago about nanotechnology engineering graduates who were developing an improved de-icer compound for use in frost removal or control. Just a couple of examples of what nanotechnology engineering students do in the area of entrepreneurship.
