Two-dimensional (2D) materials are characterised by their strong intraplanar bonding but
weak interplanar interaction. Interfaces between neighboring 2D layers or between 2D …

Graphene is a fashionable material in the realm of nanotechnology, but its potentials are
somehow misunderstood. Although a defect-free flat graphene looks perfect with …

Confined microenvironments formed in heterogeneous catalysts have recently been
recognized as equally important as catalytically active sites. Understanding the …

Graphene-based materials have attracted considerable attentions due to their unique
properties. However, the negligible and uncontrollable band gap of graphene greatly limits …

The state of the surface near-region during CO hydrogenation of Ni (111) and Ni (211)
single crystal surfaces was investigated using various gas mixtures between 150 and 500 …

While various excitonic insulators have been studied in the literature, due to the perceived
too-small spin splitting, spin-triplet excitonic insulator is rare. In two-dimensional systems …

In recent years, first-order and second-order topological phonons have been discovered in
crystalline materials, which has aroused great interest. In the present work, through …

The first hydrogenation step of benzene, which is endergonic in the electronic ground state
(S0), becomes exergonic in the first triplet state (T1). This is in line with Baird's rule, which …

The terms of topological and quantum stabilities of low-dimensional crystalline carbon
lattices with multiple non-equivalent sublattices are coined using theoretical analysis …

By means of a combination of surface-science spectroscopies and theory, we investigate the
mechanisms ruling the catalytic role of epitaxial graphene (Gr) grown on transition-metal …
