Ripples of Impact In a ground breaking collaborative research between Australia, United States and Israel, Prof. Lior Elbaz led the development of a method based on Fourier transform alternating current voltammetry to monitor the health of fuel cells in operando. This work was published this year in Nature Catalysis. Prof. Eli Sloutskin and collaborators’ study, published in Nature Physics, reported the first observation of molecules of a guest substance forming ordered selfassembled patterns on the surfaces of liquid nanodroplets. The researchers elucidated the physics underlying the patterning and developed a method for pattern control. The observed phenomenon is at the convergence point of such remote fields as two dimensional crystallography, thin-plate elasticity, interfacial energetics and mathematical topology. The method of pattern formation can be used for engineering of smart metamaterials and may have numerous far-reaching applications in medicine, the food industry, water purification and more. Prof. Sharon Shwartz has improved X-ray computational ghost fluorescence imaging performance. His study, published in Optica, shows that measuring the light emitted from the scanned objects instead of that which passes through them provides more accurate and detailed data; it also allows mapping and analyzing a broader spectrum of materials. Among other fields, this improvement promises to impact us all, potentially increasing medical X-ray examination quality while reducing patients’ exposure to its harmful radiation. 21
