In a review published earlier this year in Advanced Materials, Assistant Professor of Chemical and Biomolecular Engineering Piran Kidambi and his team explored new interest in using materials only one atom thick for membrane applications. They explained the landscape on how the technology evolved and advanced and how the field is ripe for collaborations. Their technology road map suggested that research on two-dimensional materials and membranes were once separate fields, but synergistic opportunities are resulting in exciting new developments at their intersection.
Kidambi and his team more recently applied that overlap in their own work to address some of the most critical challenges in membrane research: achieving high flow-through membranes without compromising filtration performance.
Team - Methods - Holes - Material - Team
The team initially focused on developing methods to directly form nanoscale holes into an atomically thin material. The team dialed down the temperature during graphene and found this resulted in nanoscale holes -- missing carbon atoms from the two-dimensional layer of them bonded in a hexagonal lattice.
"It reminded me of decreasing the temperature while baking a chocolate cake to get a different texture," Kidambi said.
Graphene - Nanoscales
However, the atomically thin graphene with nanoscales...
