A drop of rubbing alcohol and office laminator provides manufacturability boost for single atom thick membranes
Mar. 31, 2021—Vanderbilt engineers used a drop of rubbing alcohol, an office laminator and creativity to develop scalable processes for manufacturing single atom thin membranes. Their membranes outperformed state-of-the-art commercial dialysis membranes and the approach is fully compatible with roll-to-roll manufacturing. Details of the imaginative experiment are recently published in the journal of the Royal Chemistry Society: “Scalable Synthesis...
Engineers develop better graphene sieve that could advance clean water efforts
Sep. 23, 2020—Developing atomically thin graphene membranes used to separate salt from water is extraordinarily complex and the effort grows more crucial as population growth, industrialization and climate change strain freshwater resources. Vanderbilt engineers have designed a simple defect-sealing technique to correct variations in pore size in graphene membranes. Vanderbilt engineering researchers report a breakthrough in scalable...
