TL;DR: Microporous carbon materials used for CO₂ capture were synthesized by the chemical activation of polyindole nanofibers at temperatures from 500 to 800 °C using KOH, which resulted in nitrogen (N)-doped carbon materials, which remained remarkably stable even after 10 cycles.

TL;DR: The structures, binding energies, electronic properties, and IR spectroscopic features have been investigated by using the density-functional theory, second-order Moller-Plesset perturbation theory, and coupled clusters theory with single, double, and perturbative triplet excitations.

TL;DR: In this article, various levels of ab initio theory using various basis sets have been tested for the energy, structure, and harmonic vibrational frequencies of the water monomer, and the results showed that at the Hartree-Fock (HF) level frequency shifts in the dimer relative to the monomer were underestimated, while at the MP2 level these are overestimated.

TL;DR: This paper showed that quasi-one-dimensional indium chains on the Si(111)-$(4\ifmmode\times\else\texttimes\fi{}1)$ surface are stabilized with lattice distortions of the two zigzag indium rows composing the chain.
