Transforming CO2 into valuable products
Waterloo research team partners with BMO to turn pollution into renewable energy By Nicola Kelly Faculty of Engineering An interdisciplinary research team from the University of Waterloo aims to tackle CO2 emissions in the value chain by transforming CO2 into valuable chemicals needed by industry. Supported by BMO, the research focuses on the use of green hydrogen to capture CO2 from power plants as well as the iron, steel, and cement industries, and convert it into useful gases via reverse water gas shift reaction.

Velvet Worm slime could inspire sustainable synthetic materials
Fibers produced from the slime exhibit a strength akin to nylon, yet they can dissolve in water and be reconstituted into new fibers from the solution In the tropical, temperate forests it calls home, the velvet worm uses a projectile "slime" to capture its prey. When it's ejected from the worm, the slime transforms into a gel before solidifying into stiff fibers upon exposure to air.

Deep-sea impacts of climate interventions
Waterloo professor is part of an emerging field that calls for establishing a governance framework for ocean-based climate interventions Faculty of Environment From its current capacity as a carbon sink to its potential as a site for generating renewable energy, and managing solar radiation, the ocean is increasingly at the forefront of discussions around climate mitigation strategies. However, efforts to develop ocean-based climate interventions expose the ocean to various threats that harm biodiversity, pollute, and change its very chemistry.

Some "broken" nanomachines better sense their environment while others gain the ability to control their activity over time, researchers at Université de Montréal find. CONTENU - "Every act of creation," Picasso famously noted, "is first an act of destruction." Taking this concept literally, researchers in Canada have now discovered that "breaking" molecular nanomachines basic to life can create new ones that work even better.

New discovery may be key to controlling chemical reactions
Unexpected resonance frequencies observed in reactions between two molecules A new study published today in Nature is changing our understanding of chemical reactions and overturning previous theoretical models by finding an unexpected resonance frequency during the reaction of two molecules. Resonance is when one object vibrating at the same natural frequency as a second object forces that second object into vibrational motion.
