Solution-phase self-assembly of nanocrystals into mesoscale structures is a promising strategy for constructing functional materials from nanoscale components. Liquid environments are key to self-assembly since they allow suspended nanocrystals to diffuse and interact freely, but they also complicate experiments. Real-time observations with single-particle(More)
Epitaxial transition metal films have recently been introduced as substrates for the scalable synthesis of transferable graphene. Here, real-time microscopy is used to study graphene growth on epitaxial Ru films on sapphire. At high temperatures, high-quality graphene grows in macroscopic (>100 μm) domains to full surface coverage. Graphene nucleation and(More)
This paper compares the cathodic reactions occurring on steel in aqueous solution containing dissolved H 2 S or CO 2. In aqueous solutions containing these weak acids, the rate of the cathodic reaction is enhanced in comparison with strong acid solutions at the same pH. In the case of dissolved CO 2 , this phenomenon is fully explained by a buffer effect,(More)
