Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the “Poisson spot” to create stable patterns of light called “optical skyrmions”. Optical skyrmions are tiny, swirling configurations in the properties…
Vanadium flow batteries (VFBs) hold great promise for large-scale energy storage, thanks to their high safety, long cycle life, and flexible scalability. However, their deployment in cold climates is hindered by the poor low-temperature stability of vanadium electrolytes. In…
