This first series of images comes from specimens made available thanks to Prakesh Kumar, a graduate student with Pratim Biswas' group in Environmental Engineering at Washington University.
Tantalum oxides: low mag (LHS bar is 0.2 μm vertical) anhedral shapes?
HREM negative (LHS bar is 60nm vertical) shows TWO particle size-ranges
HREM negative, zoomed in: Are small and large the same phase?
Second series: This aerosol catalyst specimen was made available thanks to Kuk Cho, another Washington University graduate student with Professor Biswas.
Are they anhedral, subhedral, or euhedral, and can you tell from the fringes what comes after T.......?
If you like pin-stripes, how about twin-stripes?
