Have you ever come across materials with zero energy penalty for creating stacking faults? Check out our paper on TlGaSe2:

From streaked SAED patterns, we could model the faults. TEM is indeed handy to look at defects!

My streak of microscopy on energy materials continues. This Birnessite NaxMnO2 rods are promising for Na-ion batteries! Give this a read:

Hopefully we'll have more soon about their structural part 😉

Fresh from the press on how nanoclusters influence the water splitting. The collaboration with Indra's experimental group has been super-fun, and our Paramshakti facility at IIT Kharagpur has been quite the workhorse! Well-done to the authors.
