The discovery of molecular switches at room temperature opens the door to faster computers and longer-lasting batteries

Researchers at the University of Queensland have solved a problem that has frustrated physicists and chemists for many years. This could lead to new, more efficient and environmentally friendly technologies.

Professor Ben Powell, UQ's School of Mathematics and Physics, has created a "recipe", which allows molecular switches at room temperature to function using quantum mechanics.

Professor Powell stated that switches are materials that can switch between two or more states such as on or off, 0 or 1, and are the foundation of all digital technologies. This discovery opens the door to smaller, more powerful, and more efficient technologies. It is possible to expect batteries to last longer and computers will run faster.

Molecular switching was previously only possible at extremely low temperatures (below minus 250 degrees Celsius). Professor Powell stated that engineering-wise, this problem is very serious.

Chemists will be able to make molecular switch work at room temperature by following this detailed "recipe".

"This will allow for a wealth of technological advances, such as the improvement of MRI scans that could lead to earlier detections of cancerous diseases."

These materials can be used as sensors, carbon capture, storage, hydrogen fuel cell, and actuators. They can convert electricity into movement which could be useful for robots.

"All these applications require materials that can switch at or above ambient temperature. This is why our discovery was so important."

These materials will reduce the environmental burden by reducing computer energy consumption, which will aid in the fight against climate change.

Researchers from UQ will collaborate with chemists from the University of Sydney, University of New South Wales to create new materials for testing the "recipe".

The journal of the American Chemical Society published the research.
