Journal Article
Preobrajenski, A., Vinogradov, N., Duncan, D. A., Lee, T.-L., Tsitsvero, M., Taketsugu, T., & Lyalin, A. (2024). Boron-induced transformation of ultrathin Au films into two-dimensional metallic nanostructures. Nature Communications, 15(1), Article 10518. https://doi.org/10.1038/s41467-024-54464-y

The synthesis of large, freestanding, single-atom-thick two-dimensional (2D) metallic materials remains challenging due to the isotropic nature of metallic bonding. Here, we present a bottom-up approach for fabricating macroscopically large, nearly f...

In light of the recent research interest in low-dimensional bismuth structures as spin-active materials and topological insulators, we present a comprehensive characterization of the Bi/Au(111) interface. The nuanced evolution of Bi phases upon depos... Read More about Holistic structural understanding of epitaxially-grown Bi/Au(111) moiré superstructures.

Quantitative Measurement of Cooperative Binding in Partially Dissociated Water Dimers at the Hematite “R-Cut” Surface (2024)
Journal Article

Quantitative Measurement of Cooperative Binding in Partially Dissociated Water Dimers at the Hematite “R-Cut” Surface. Journal of Physical Chemistry C, 128(40), 16977-16985. https://doi.org/10.1021/acs.jpcc.4c04537

Water-solid interfaces pervade the natural environment and modern technology. On some surfaces, water-water interactions induce the formation of partially dissociated interfacial layers; understanding why is important to model processes in catalysis...
