Direct Imaging of Band Profile in Single Layer MoS2 on Graphite: Quasiparticle Energy Gap, Metallic Edge States, and Edge Band Bending
TL;DR: Using scanning tunneling microscopy and spectroscopy, a single-layer MoS2 on graphite was investigated in this article, where the apparent quasiparticle energy gap was measured to be 2.15 ± 0.06 eV at 77 K, albeit a higher second conduction band threshold at 0.2 eV above the apparent conduction bands minimum.

Probing Critical Point Energies of Transition Metal Dichalcogenides: Surprising Indirect Gap of Single Layer WSe2
Chendong Zhang,Yuxuan Chen,Amber Johnson,Ming-Yang Li,Ming-Yang Li,Lain-Jong Li,Patrick C. Mende,Randall M. Feenstra,Chih-Kang Shih +8 more
TL;DR: Detailed quasi-particle electronic structures in transition metal dichalcogenides are revealed, including the quasi- particle gaps, critical point energy locations, and their origins in the Brillouin zones by using a comprehensive form of scanning tunneling spectroscopy.

Interpersonal chemistry through negativity: Bonding by sharing negative attitudes about others
TL;DR: The authors found that sharing negative attitudes about a target person predicted liking for a stranger more strongly than discovering a shared positive attitude (but only when attitudes were weak) and that positive attitudes about others would be particularly effective in promoting closeness.

TL;DR: The precise geometric arrangement between fluorescent nanoparticles and silver nanoplatelets allows us to make, for the first time, a comparative analysis between experimental results and numerical simulations, yielding a quantitative agreement at the single particle level.
