SUBJECT: This image shows large titanium carbide (Ti3C2Tx) multilayered MXene, resembling a sea sponge over the coral landscape. The multilayered Ti3C2Tx MXene flakes were synthesized by selective etching of Al layers from Ti3AlC2 MAX phase using hydrofluoric acid; CREDIT: Nithin Chandran and Prof. Babak Anasori, Purdue University; METHOD/INSTRUMENT: JEOL JSM-7800F FE SEM
