Abstract:

 Comprehensive tools of materials modeling are derived from the principles of physics and chemistry, empowered by high performance computing. Together, this allows one to make verifiable predictions of novel physical structures with specific, often useful or even extraordinary, properties. Nanotubes offer one such lesson [1], where atomic makeup and defects dynamics lead to understanding their strength and failure physics on one hand, while also reveal the origins of chiral symmetry in nano-carbon synthesis [2]. Second, very recent, example is the prediction of pure mono-elemental boron 2D B, its particular structures to form on Ag(111), which culminated in recent experimental confirmations. We may also mention, if time permits, its physical properties like new 2D-superconductor [3], now-detected Dirac cone dispersion, still-sought 2D-plasmonics, and catalysis.
