Crystallization Pattern of a Common Salt Mixture

Lithium-ion batteries (LIBs) are rechargeable energy carriers that power electronic devices such as phones, cars, and hybrid/electric vehicles. The demand for lithium used to manufacture LIBs is expected to grow 30-fold by 2040. Industry primarily extracts lithium from rock ore and brine; however, the methods used are time-intensive and costly. Therefore, we are investigating alternative extraction methods that would reduce the energy consumption, waste production, and time intensity. The image, obtained by microscopy, is of salts that crystallized after evaporation of a lithium-containing brine.

Lithium is an element that is key to our energy transition away from fossil fuels and plays an important role in the battery technologies for space exploration. This photo was taken during an expedition to Western Australia exploring for lithium deposits that have the potential to reshape the global economy and resolve the global climate crisis.

This photo taken with scanning electron microscopy depicts an extremely small yet precise volume (i.e., nanolitre-sized) of crystallized decanoic acid. We are using these spots of crystalline acid to extract and preconcentrate, or soak-up, chemicals of concern like opioids from wastewater samples. This preconcentration step improves our ability to monitor these chemicals. By doing so, we can improve how we detect these harmful compounds and protect local watersheds.

Shattered Planet

The impact of human activity on our planet is often difficult to see in the moment, and requires a long-term, overlooking, view. This photo is a drone panorama of my field site on the Rideau Canal System, where I investigate the impact of human activity on aquatic ecosystems, particularly the development of toxic algal blooms. Activities such as fishing, property development and farming have fragmented and altered this ecosystem, and we need a holistic, broader view to piece together how we can protect our delicate, beautiful, world.

Algal blooms appear as smears of green slime from the ground, but are beautiful pieces of abstract art from an aerial view, painted by wind and sunlight. My research takes me to lakes on the Canadian Shield affected by blooms, where I photograph them with a drone while assistants help me collect water samples. By uncovering when, where, and why they appear, we hope to restore some of Canada’s most beautiful lakes to their pristine states.

Engineering Solutions: Leachate, liners, landfills, and learning

MLR7 — Tue, 24 Sep 2019 17:24:46 +0000

Human beings have undoubtedly been throwing things away for as long as we have had things to throw. These ancient middens – the predecessors of our modern landfills – provide a treasure trove of artefacts for archaeologists, who sift through discarded items for clues to how people once lived.

For the past 40 years, Kerry Rowe's research has focused on natural environmental components along with engineering principles to improve our ability to safely discard materials with more confidence that they will not come back to haunt us.

Kerry Rowe, Canada Research Chair in Geotechnical and Geoenvironmental Engineering and professor in the Department of Civil Engineering, explains his ongoing research on landfill management and how he is developing techniques that work with nature rather than fighting nature.

Love to Eat Oil

Oil spills are a significant threat to marine wildlife and human health. Nature has evolved an effective way to rectify this problem using indigenous bacteria to clean up the oil contaminants. My research focuses on studying the microscale interaction of bacteria with oil droplets to better understand the mechanisms of oil degradation by the bacteria. The picture shows oil-degrading bacteria (gray) finding an oil droplet (orange), forming biofilms around it (green), and eventually breaking it down into harmless compounds.

Platinum Surface Electrochemistry

The single crystal of platinum gently hangs atop an electrolyte surface. Electrochemistry is a surface-sensitive field of research, as the composition and atomic arrangement of the electrode drastically affect its properties. Atoms in a single crystal are highly ordered, and we are able to cut and polish a crystal in such a way that we only expose one of the many possible surface arrangements. The single crystal electrode is balanced on the surface of the electrolyte to ensure that only the polished surface is exposed. These experiments give us fundamental information about electrochemical reactions, which are integral to the field of clean energy.

The Wide-ranging Applications of Polymeric Materials

How can we reduce engine wear and improve fuel economy? How can surfaces be made that are highly resistant to contamination? Dr. Guojun Liu, Canada Research Chair in Materials Science, thinks the answers may come from the development of polymeric materials.

These materials comprise both natural and synthetic materials with a wide variety of properties.
