Producing hand sanitizer for local hospitals

kvd1 — Tue, 02 Jun 2020 03:01:00 +0000

The COVID-19 pandemic has led to worldwide shortages of personal protective equipment and, very early on, products like hand sanitizer. This has a great impact on hospitals where these products are critical to limiting the spread of the virus, especially for frontline health care workers and patients.

The photograph is of a water-swollen hydrogel particle created in our chemistry laboratory, taken with an instrument called a Scanning Electron Microscope, which allows us to zone in and see important details on the surface of the hydrogel. A hydrogel is essentially a plastic material that is able to absorb very large volumes of water (up to 800 times its weight!) – much like a baby diaper, swelling as it does so. From the image, the surface of the hydrogel is seen to possess large, distinctive pores, which help us understand how and why hydrogels absorb so much liquid.

Exploring Chemical Reactions in Bacteria

Chemical reactions are taking place deep within the cellular structure of living organisms. These reactions control biological events and are part of the processes that regulate metabolism, gene expression, and cell division, as well as growth, development, locomotion, learning, and memory.

Helping Chemistry Go Green

Most people recycle used cans, bottles, and paper, but how many consider recycling carbon dioxide? Power plants, cement factories, and breweries rarely recycle the carbon dioxide they emit as waste gases.

Dr. Philip Jessop, Canada Research Chair in Green Chemistry, wants to make the chemical and energy industries greener by identifying ways of recycling waste carbon dioxide. Dr. Jessop believes reusing carbon dioxide can help the environment and make industrial processes more efficient and economical, using less energy and fewer raw materials.

Why Everything Works: Shining a Light on Molecular Processes

When you swallow a life-saving drug or recharge your iPod’s battery, you rarely think about the atoms and molecules that allow these things to work: all you care about is that they do. But, in order for everything from pharmaceutical drugs to energy-storage devices to work, very important things have to happen at the sub-microscopic level. For these devices to work even better in the future, we need to understand what is happening inside them, at the smallest possible level.

Whether she’s working in the classroom or on the other side of the world, Dr. Cathy Crudden’s chemistry creates all sorts of connections.

I’m a bit early for my meeting with Dr. Cathy Crudden, so when I arrive at her office she’s in the middle of discussing a current research project with one of her students. Crudden invites me in anyway and it’s immediately obvious that working with students is a huge job perk for her.
