Lithium-ion batteries are being used in a growing number of everyday devices—cellphones, laptops, electric vehicles—and it is important to reduce their life-cycle environmental impacts reduced to a minimum. Mickaël Dollé is working to make them greener. He has already patented a technique for recovering cathode materials from lithium-ion batteries to make new batteries without generating waste. Batteries can now be produced in a circular economy-type closed loop.

A chemist by training, Dollé has a general interest in ecodesign: how batteries can be made with less energy and greener materials. One way is to replace fluorine-based materials that require the use of toxic solvents and complicate recycling with new polymers. In 2020, Dollé and his colleagues designed a battery made from water and wood, an achievement that was selected as the scientific discovery of the year by the readers of Québec Science magazine.

Before joining the University of Montreal in 2014, Dollé completed postdoctoral studies at the Lawrence-Berkeley National Laboratory and the Max Planck Institute for Solid State Research in Stuttgart. He also worked as a researcher at the CNRS in France.

The research program of his Courtois Chair focuses on high-throughput screening of glasses and glass ceramics through the automation of synthesis and physicochemical characterization, supported by simulations. While there are several tools available to predict the existence and properties of crystalline materials, especially for batteries, there is no equivalent tool for glasses and glass ceramics. Machine learning algorithms can use this database to assist us in the rational design and development of glasses and glass ceramics with controlled properties and/or new phases.

Solid-state chemistry, materials science, and electrochemistry will be at the core of the activities, with a strong interest in understanding the relationship between development (synthesis and processing)/microstructure/properties in order to improve existing materials or create new ones.

The targeted outcomes include generating fundamental knowledge related to energy transition and the exploration of innovative concepts in order to design novel materials for future technologies.

William Witczak-Krempa is interested in materials that display quantum properties at low temperatures. For example, some materials lose electrical resistance and become superconductors, which have important practical applications, from lossless electricity transmission to the manufacture of extremely powerful magnets. 

However, low temperatures limit large-scale production. Could quantum materials be created at higher temperatures and be made more accessible to humans? William Witczak-Krempa’s team is tackling the question using a variety of mathematical and numerical tools, including artificial intelligence.

Understanding matter at the quantum level is essential for, among other things, the creation of a quantum computer, the device physicists and computer scientists dream of. Its computing power would far exceed that of any existing computer. 

William Witczak-Krempa came to the University of Montreal after completing two postdoctoral fellowships, one at the Perimeter Institute in Waterloo and the other at Harvard University. He is the Canada Research Chair in Quantum Phase Transitions and a member of the Regroupement québécois sur les matériaux de pointe (RQMP), and the Centre de recherches mathématiques (CRM).

Ahmad Hamdan has been a professor in the Department of Physics at the Université de Montréal since 2017. He specializes in the physics of plasmas, with a particular focus on those generated in a liquid medium. The plasmas he studies exhibit novel properties in terms of temperature (1000s K), pressure (10s bar), species density (1017-19 cm-3) and lifetime (100s ns). Unlike conventional plasmas, liquid plasmas represent extremely efficient and environmentally-friendly processes for the production of nanomaterials, among other applications.
The inherent flexibility of these processes enables plasmas to be initiated and maintained in various liquids, including water, hydrocarbons and cryogenic liquids. In addition, the use of electrodes with a variety of chemical compositions contributes to this versatility.

Spider silks, mother-of-pearl, cell membranes and tree fibrils are all natural materials with exceptional properties thanks to a combination of molecular order and disorder. Chemists also exploit molecular order to design functional materials such as bullet-proof vests and display devices.

It is in this context that Christian Pellerin and his team fabricate partially ordered molecular materials and study them to understand how to optimize their performance. Their work focuses on highly oriented electrospun fibers, light-induced order in photoactive materials, order in ultrathin films (with Antonella Badia), and amorphous molecular materials that resist ordering. The group specializes in the physicochemical characterization of materials, with particular emphasis on vibrational spectroscopy. On a more applied front, the Pellerin team works with industrial and governmental partners to improve polymer recycling and to create materials useful for national defence.

After completing his PhD at Université Laval and a postdoctoral fellowship at the University of Delaware, Christian Pellerin joined the Université de Montréal’s Department of Chemistry in 2005, where he founded his Materials Spectroscopy Laboratory. He is also the director of the LCMP platform (Laboratory for polymer materials characterization).

François has been a professor in the Department of Physics at the University of Montreal since the year 2000. He specializes in the synthesis and characterization of semiconductors and amorphous materials, particularly through ion beam analysis: by bouncing particles produced by an accelerator, one can identify the atoms that make up a sample and their distribution in depth at the nanometer scale. This is very useful for determining whether thin-film compounds synthesized for a wide range of applications, from microelectronics to wear-resistant coatings for aircraft reactors, have the desired values. In recent years, he has been interested in the fabrication of low-noise mirrors, particularly in the context of gravitational wave detectors (GWD). Indeed, in several ultra-high precision systems such as quantum computers, atomic clocks, and GWDs, sensitivity is limited by the fact that the materials of the mirrors can reconfigure or their properties can otherwise fluctuate, causing noise. His group is therefore searching for materials that minimize these phenomena while meeting the many other constraints imposed by these applications.

Gilles Brassard is considered the founding father of quantum information science in Canada and one of its earliest pioneers in the world. Working with physicist Charles Bennett (IBM Research), he created a protocol that laid the foundations for quantum cryptography, which is the key to unconditionally secure communications. In 1992, he developed the theoretical protocol for quantum teleportation, in collaboration with Bennett and four other colleagues including Claude Crépeau, now at McGill University. In 1998, this theory was verified experimentally by another team of researchers, a feat that was selected by the journal Science as one of the 10 Breakthroughs of the year. In 2018, those two discoveries earned him and Charles Bennett the Wolf Prize in Physics, often considered a forerunner to the Nobel Prize. He was the first Canadian to be awarded the Wolf Prize in Physics.

Brassard’s work is foundational in quantum information science, an emerging field with the potential to create computers immeasurably more powerful than conventional computers by exploiting sometimes-counter-intuitive manifestations of quantum theory. 

Gilles Brassard is a Montreal native who has been passionate about mathematics since he was a child. He enrolled at the Université de Montréal at age 13 to earn a bachelor’s degree and then a master’s degree in computer science. In 1979, he completed a Ph.D. in cryptography at Cornell University and became an assistant professor at the Université de Montréal the same year. He held the Canada Research Chair in Quantum Information Science for 21 years from 2001 until 2021. He founded and is now the scientific director of INTRIQ, the Transdisciplinary Institute for Quantum Information.

James Wuest wants to learn how the properties of materials depend on the molecules they contain and on how they are organized. Once the basic rules are mastered, novel materials can be built by design from molecular components specifically synthesized for the purpose.

The ability to create on the molecular scale led Wuest to choose a career in organic chemistry.

My group’s expertise lies in electronic structure calculations using methods such as density functional theory. This approach uses quantum mechanics to calculate material properties. Our approaches are based on first physics principles and therefore, require no experimental parameters. As a result, we can predict the properties of new materials and explore new ideas to deduce the most promising leads. Our calculations are also highly valued by our experimental collaborators, as we can calculate the properties of the systems they are studying without theoretical bias. My group members are developers of the ABINIT open-source code that implements these approaches.

Philippe St-Jean, holder of a Research Chair in Quantum Photonics from the Ministère de l’Économie et de l’Innovation du Québec, studies the interaction of light and matter in the quantum regime.

When a classical light bulb is turned on, billions of electrons move in all directions and their motion emits light. Philippe St-Jean is interested in the movement of individual electrons in microscopic detail, which is governed by quantum mechanics. By placing single electrons in optical cavities, which act as sounding boards for light, he is able to tailor with a high precision the photonic modes to which they couple. For example, he can engineer cavities where light flows in a single direction or is trapped for an extended period of time.

In addition to better understanding complex quantum phenomena at the single electron level, his work paves the way to the conception of more robust and precise quantum light sources, which are particularly useful in quantum cryptography. Philippe St-Jean’s work can also be transposed to trap photons in cavity arrays to simulate new materials. 

Philippe St-Jean has worked at the Centre for Nanoscience and Nanotechnology at CNRS and the University of Paris-Saclay. He became a professor in the Department of Physics in the summer of 2021.

When you look at your smartphone, you see a host of vibrant colours. It most likely has not occurred to you that a considerable amount of research has gone into making that happen. Rationally designing and preparing compounds that emit a rainbow of colors for use in such electronic devices is a part of Professor William Skene’s research.

Pr. Skene’s research team also focuses on making materials that are both flexible and stretchable for use in organic electronic devices such as smartphones. The team’s research is paving the way for the next generation of plastic electronics that will be bendable, stretchable, and unbreakable. His team also works on developing environmental benign processes for device fabrication along with integrating renewable resources into devices. These approaches will reduce the waste generated during device fabrication and they will improve the lifecycle management and sustainability of electronics.

Pr. Skene values interdisciplinary collaborations because discoveries can be integrated into every step of the device fabrication chain from materials synthesis to processing and device upscaling.

Pr. Skene decided on a career in chemistry because he wanted to understand how things worked on a molecular level. The Winnipegger pursued post-doctoral studies in France at the Université de Strasbourg (formerly Université Louis Pasteur) before joining the Université de Montréal in 2003.

Yoshua Bengio is a world-leading expert in artificial intelligence whose pioneering work on deep learning earned him and his colleagues Geoffrey Hinton and Yann LeCun the A.M. Turing Award in 2018. The Turing is considered the Nobel Prize of computer science. 

Deep learning is a branch of artificial intelligence that exploits artificial neural networks to create new generations of algorithms that can help computers learn by themselves. In deep learning, information is processed through a sequence of operations modelled on the way the brain works, in which multiple neural layers form a deep network. 

Today, neural networks are driving advances in fields ranging from natural language processing and machine translation to protein structure modeling, voice and facial recognition, robotics, self-driving vehicles, medical image analysis, drug discovery, weather simulation, and even managing power outages and vehicular traffic.

Yoshua Bengio has been instrumental in making Montreal a hub of AI research. He is the founder and scientific director of Mila, the Quebec Artificial Intelligence Institute, and the scientific director of IVADO, the Institute for Data Development. Around these two flagship AI institutions, a scientific ecosystem of more than 1,000 researchers has grown in the vicinity of the MIL campus in recent years. 

Concerned about the social impact of his work and that of his colleagues, Yoshua Bengio actively contributed to the Montreal Declaration for a Responsible Development of Artificial Intelligence and co-directed the Global Partnership on Artificial Intelligence (GPAI) Working Group on Responsible AI.
