University of Queensland scientists have cracked a problem that’s frustrated chemists and physicists for years, potentially leading to a new age of powerful, efficient, and environmentally friendly technologies. Using quantum mechanics, Professor Ben Powell from UQ’s School of Mathematics and Physics has discovered a “recipe” which allows molecular switches to work at room temperature.

“Switches are materials that can shift between two or more states, such as on and off or 0 and 1, and are the basis of all digital technologies,” Professor Powell said. “This discovery paves the way for smaller and more powerful and energy-efficient technologies. You can expect batteries will last longer and computers to run faster.” [1]

Figure 1 shows "You can expect batteries will last longer and computers to run faster." Until now, molecular switching has only been possible when the molecules are extremely cold -- at temperatures below minus 250 degrees centigrade. "Engineering-wise, this is a big problem," Professor Powell said. "By following this detailed 'recipe', chemists should be able to make molecular switches work at room temperature. [2]

This can open the door to a bounty of technological developments, similar to bettering MRI scans which might result in earlier detection of illnesses like most cancers. These supplies can be used for sensors, carbon seize and storage, hydrogen gas cells, and as actuators, which might flip electrical energy into motion, which might be helpful for robots.

All of those purposes want supplies that may be switched at or above room temperature, which is why our discovery is so necessary. [3]

"Using these materials will also reduce the burden on the environment because computer energy use will be cut, aiding the fight against climate change." [2]

UQ researchers will probably be collaborating with chemists on the College of Sydney and College of New South Wales, to make new supplies to check the brand new ‘recipe’. [3]
