Researchers at Aalto University and the Technical University of Denmark have developed an artificial intelligence (AI) to seriously accelerate the development of new technologies from wearable electronics to flexible solar panels. ARTIST, which stands for Artificial Intelligence for Spectroscopy, instantly determines how a molecule will react to light -- clinch-pin knowledge for creating the designer materials needed for tomorrow's technology.
Scientists traditionally study molecular reactions to external stimuli with spectroscopy, a widely used method across the natural sciences and industry. Spectroscopy probes the internal properties of materials by observing their response to, for example, light, and has led to the development of countless everyday technologies. Existing experimental and computational spectroscopy approaches can be, however, incredibly costly. Time in highly specialised laboratories is expensive and often severely limited, while computations can be tedious and time-intensive.
With ARTIST, the research team offers a paradigm shift to how we determine the spectra -- or response to light -- of individual molecules.
'Normally, to find the best molecules for devices, we have to combine previous knowledge with some degree of chemical intuition. Checking their individual spectra is then a trial-and-error process that can stretch weeks or months, depending on the number of molecules that might fit the job. Our AI gives you these properties instantly,' says Milica Todorovic, a postdoctoral researcher at Aalto University.To read more, click here.
