TU Wien Quantifies Nanosecond Water Ordering, Debunking Ion Adhesion Myths
2 articles · Updated · BIOENGINEER.ORG · May 19
TU Wien-led researchers showed that water structures around ions persist only on nanosecond timescales, undermining claims that water can store long-lived “memory.”
Using atomic force microscopy, molecular dynamics simulations and spectroscopy, the team built a thermodynamic model linking ion adsorption to both electrostatic attraction and the entropy cost of disrupting ordered hydration shells.
Small, high-charge-density ions such as lithium impose stronger water ordering than larger ions like cesium, and that stronger ordering makes them less likely to stick to charged surfaces despite favorable charge interactions.
The result gives a more predictive framework for interfaces in batteries, fuel cells, catalysts and biological membranes, where ion transport and surface binding shape performance.
Is the secret to next-gen batteries and resource mining hidden not in metals, but in water's fleeting structure?
How does the invisible 'shell' of water around an ion dictate the function of batteries and even our nerve cells?
