As an inorganic chemist, Dr. Saurabh Chitnis says he explores the part of the periodic table that doesn鈥檛 get a lot of attention. He looks past those superstars of organic chemistry 鈥� carbon, hydrogen, nitrogen, and oxygen 鈥� that hog limelight, to the 114 remaining elements that make up the rest of our universe.
But 114 is a lot too choose from. Where to start? In a word, beauty.
鈥淚t comes from my fascination with beautiful structures. Students in my lab and I are really drawn to molecules that exhibit structural attractiveness,鈥� says Dr. Chitnis. 鈥淚t really starts from this point of beauty and then we tease out the chemical consequences of that structure. When we do this, we make fascinating discoveries.鈥�
This novel approach has attracted the recognition of the , which is awarding Dr. Chitnis with a 2023 Sloan Research Fellowship. The award is accompanied by $75,000 USD to fund research over two years. With Canadians sparsely represented in the fellowship, Dr. Chitnis is the just the second member of 麻豆传媒鈥檚 faculty to receive the honour.
Fundamental appreciation
Dr. Chitnis says he is especially pleased to receive the fellowship as it is one of the world鈥檚 few high-profile academic awards that recognizes the importance of fundamental science with no immediate expectation for real-world application.
鈥淚t recognizes that it鈥檚 fundamental science that drives our collective knowledge base forward. And for us, it was a validation of our curiosity-driven approach, an approach that is all about just looking at the microscopic features of something and trying to understand the macroscopic consequences of its structural beauty.鈥�
So, what makes a molecule beautiful? Dr. Chitnis says it鈥檚 something elemental that strikes humans instinctively. He says we crave symmetry. It鈥檚 nature鈥檚 way of saying things are in order.聽
鈥淭here is something more aesthetically pleasing about a sphere than a random, oblong shape. The concept of symmetry is so deeply ingrained within us that we see manifestations of it everywhere, and particularity in structural chemistry. It鈥檚 impossible not to see it.鈥�
Dr. Chitnis works with a student in his lab.
Not beauty for beauty鈥檚 sake
While Dr. Chitnis鈥� scientific inquiry begins with a molecule that strikes his fancy, the process of getting to know it is often a lengthy and rewarding courtship. It begins on a computer, where a target molecule that has never been created in the real world is dreamed up and modelled. Then Dr. Chitnis and his graduate students are off to the synthetic chemistry lab to make the molecule a reality. In the process they learn a great deal about chemical interactions that push science forward. The work has seen many discoveries, including novel ways of making molecules used in the production of pharmaceuticals.
鈥淲e were the first to make a single bond between antimony and bismuth elements in a way that no one else has ever connected them before,鈥� says Dr. Chitnis, by way of an example. 鈥淪o that's been the overall thrust of our research 鈥� to explore fundamentally interesting and beautiful molecules. In trying to explain to ourselves why these molecules are interesting, we end up discovering valuable properties for them.鈥�
Commercial appeal
While not the goal, sometimes their discoveries lead to applications that can make the leap from the lab. Currently, Dr. Chitnis is working with 麻豆传媒鈥檚 Office of Commercialization and Industry Engagement to secure a patent for a molecular structure which promises to revolutionize the way we create materials.
鈥淔or the entire history of polymer and material chemistry, we've made some assumptions that you must make polymers out of hydrocarbons, fossil fuels, ethylene, and so on. Secondly, that you must make materials out molecules in one-dimensional chains or two-dimensional ring structures. What we've demonstrated is, that you can connect three-dimensional molecular cages together without a hydrocarbon backbone,鈥� says Dr. Chitnis.
It's a discovery that may catch the eye of industrial partners keen to leverage the new chemistry to build materials with desirable new properties currently not possible, and without the input of fossil fuels derivatives.
Dreamer of dreams
While Dr. Chitnis is excited about the potential for the discovery, he is happy to see it advanced and commercialized by fellow scientists and engineers. His first love will always be the molecules he dreams into reality.
Words of inspiration.
He says he has a rule that he doesn鈥檛 talk about chemistry before he goes to bed, for fear that he will lay awake all-night thinking about the molecules he wants to create.
鈥淓nvisioning and making, that's what we do. I have a little hand-written sign on my office door with a quote from the Willy Wonka movie with Gene Wilder. In the movie he says, 鈥榳e are the music makers, the dreamers of dreams.鈥� That's very much how we consider our work,鈥� says Dr. Chitnis. 鈥淲e just drive the dream. And then we let others take it the next step with our input, advice and collaboration.鈥�
