The early stages of nucleation and growth of atomic layer deposition (ALD) platinum on SrTiO3 (001) have been studied. Scanning electron microscopy reveals the ALD Pt deposits as discrete nanoparticles that grow and coalesce with increasing number of ALD cycles, ultimately resulting in a continuous film after ∼40 cycles. Atomic force microscopy shows the films to be fine-grained and highly…
A practical process to synthesize bio-colloidal composites was developed on the basis of the noncovalent interactions of icosahedral plant virus turnip yellow mosaic virus (TYMV) and poly(4-vinylpyridine) (P4VP). TYMV particles fully covered the surface of a P4VP ball with a hexagon-like packing. The raspberry-like morphology of TYMV-P4VP colloids and the packing pattern of TYMV were reveale…
