Explore materials science research

New concrete blends, nanomaterials, new polymers, macrocells, biomaterials, improved aluminum manufacturing processes: materials science is an exciting field that draws on the ingenuity of chemical and materials engineering researchers who are characterizing and synthesizing molecules in order to assemble them and create composite materials with specific properties for industrial and medical applications. Our professors in chemical and civil engineering test new materials, alloys, and structures by performing physiochemical and mechanical tests to optimize performance and lifespan.

The faces of materials science research

Below is a summary of the main research areas explored by our materials science researchers. Each one includes a brief profile of the work carried out by one of our faculty members.

Aluminum production

Researchers working on aluminum are looking for ways to increase energy efficiency in processing and thus reduce greenhouse gas emissions during production and searching for ways to use waste and recycled materials. They are also working to increase quality and improve the performance of alloys produced by secondary and tertiary processing and to develop new materials and transformation processes.

Professor Darvishi-Alamdari has close ties with the Aluminum Research Centre (REGAL), where he is responsible for research on waste management and the quality of raw materials. He works to improve manufacturing techniques and specifications for carbon anodes in order to improve the electrical efficiency and chemical reactivity of carbon electrodes.

Innovative materials and products

The search for better-performing materials has led to Composite materials are composed of at least two immiscible components, a reinforcement and a matrix, which have complementary properties. Examples include carbon fibre, reinforced concrete, and pressed wood., which are less dense than metals and have a much longer lifespan. Their mechanical properties make them the materials of the future, but scientists are striving to overcome obstacles such as high production costs and limitations on recyclability.

Member of the Research Centre on Concrete Infrastructure (CRIB)

Luca Sorelli studies the microstructural and physicochemical properties of new materials in his lab L(CM)2M. It is the only lab in the province of Québec that can identify the micro and nano structures of composites and combine that information with statistics drawn from Nanoindentation is a mechanical technique for characterizing materials that is used on thin films and micro-objects. and chemical tests carried out in a controlled environment.

Synthetic and natural macromolecules

A number of researchers are involved in characterizing naturally occurring macromolecules (e.g., silk and proteins) using spectroscopic methods such as infrared and magnetic resonance. Some scientists are designing custom biofilms, while others are working on synthesizing and characterizing new polymers. Still more are studying the possibility of using cellulose in composite materials to help the plastics industry manufacture greener materials.

Sustainable infrastructure management

This field of research, which is a subdiscipline of civil engineering, involves modelling and predicting the behaviour of civil engineering structures. Researchers examine a variety of factors (mechanical, thermal, hydraulic, soil, and structural) related to complex actions such as soil movement caused by thermal or hydric strain.

What I like about the Faculty of Sciences and Engineering is that it’s like a big family—everyone respects one another and collaboration is encouraged. Despite the fact that, whether we like it or not, many of us are in competition with one another, people always come first.

Gaétan Laroche, professor, Department of Mineral, Metallurgical, and Materials Engineering

Director of the Centre for Advanced Material Research (CERMA)

Professor Laroche’s work deals with interactions between cells and the surfaces of materials and the development of biological applications for these interactions. In particular, he is working on modifying the surfaces of vascular and orthopedic biomedical materials to ensure biocompatibility. He is renowned for his contributions regarding the use of gaseous A plasma is an ionized gas containing free electrons that are not attached to an atom or molecule. Plasma is highly conductive due to the mobility of its charged particles. in modifying surfaces.

Geomaterials

Geomaterials are situated at the crossroads of earth sciences, environmental science, physics, and chemistry. There are two types: natural geomaterials (rocks, soil, etc.) and artificial geomaterials (concrete, glass, ceramics, etc.). Research in the field has gained fresh impetus recently, with scientists examining the properties of geomaterials, including the structure-property relationship and conditions of formation and evolution, conducting experiments using high temperatures and various pressure levels, and investigating the specific properties of mineral surfaces.

Professor Fournier specializes in several aspects of An aggregate is an inert material like sand, gravel, or crushed stone that is used as a ingredient in mortars or concretes. technology. For example, he investigates recycling and sustainable development with regard to cement additives, industrial waste, and aggregates, in addition to the durability of concrete, which includes alkali-aggregate reactions.

Fluid dynamics

Fluid dynamics precisely describes the movement of fluid particles (liquids and gases) in relation to the forces involved, such as velocity, viscosity, density, pressure, and temperature. Fluid dynamics and its subdisciplines such as hydraulics and hydrodynamics have many applications, notably in weather forecasting and aeronautics. They also play an important role in industrial applications such as pulp and paper, water treatment plants, and naval architecture.
