New material developed by Canadian researchers could revolutionize sectors such as energy, desalination and construction
Researchers at the Institut national de la recherche scientifique (INRS) in Canada have created a new material that converts sunlight directly into heat in a highly efficient way. This innovative technology promises to have major impacts in strategic areas such as sustainable energy generation and water treatment.
What is this new technology and why does it matter?
A group of scientists from INRS has developed a thin film of Ti₄O₇, a special phase of titanium oxide belonging to the class of “Magnéli phases”. These materials have unique chemical and electrical properties, and have been tested with the aim of absorbing sunlight and converting it directly into heat, with efficiency that surpasses traditional systems.
It photothermal technology can be applied on several fronts: from heating environments and water to passive desalination, which removes salt from seawater using only the sun's heat, without the need for electricity or expensive processes such as reverse osmosis. According to Professor My Ali El Khakani, the project leader, the application of thin films on surfaces makes the material versatile and practical for different environments.

Expected impacts and practical applications of the technology
The new material can directly benefit civil construction, promoting more efficient thermal insulation solutions, in addition to boost technologies of solar thermal energy production. Industrial sectors that require heat in their processes, such as the chemical, food and water purification industries, can also benefit from the discovery.
According to the portal Interesting Engineering, the study marks an important step forward towards a more sustainable future, in which clean technology plays a fundamental role in reducing carbon emissions and combating climate change.
