2024 SCIENCE BREAKTHROUGH
Saw Wai hla: Breaking the Wall of 128 Years of X-ray History
Saw Wai Hla's team achieved the first X-ray of a single atom, marking a milestone in X-ray science. Using synchrotron X-ray scanning tunneling microscopy, they captured spectral fingerprints of individual atoms, revolutionising nanoscale studies and material analysis.
2023 SCIENCE BREAKTHROUGH
Libor Šmejkal: Breaking the Wall to Quantum Magnets
Before altermagnets, researchers studied ferromagnets (prone to energy loss) and antiferromagnets (also inefficient due to resistance). Altermagnets solve this by conducting electricity without resistance, thanks to their unique electron arrangement and quantum properties. Libor Šmejkal presents this Science Breakthrough at Falling Walls, highlighting its potential to revolutionize efficient, sustainable electronics.
2022 SCIENCE BREAKTHROUGH
Nathalie Picqué: Breaking the Wall to Precision Measurement
Interferometers measure wave interference for precision applications in science and industry, including quantum physics, biomedicine, astronomy, and chemistry. Nathalie Picqué of the Max-Planck Institute developed a dual-comb interferometer using frequency combs (rainbows of light waves) to automatically scan interference between ultrashort pulses. Unlike traditional spectrometers, it enables direct frequency measurements and provides detailed molecular analysis. At Falling Walls, she explores how this breakthrough advances environmental gas sensing and other applications.
