Metal-organic frameworks (MOFs) have emerged as promising materials for carbon capture applications due to their high CO2 capacities and tunable properties. Amongst the many possible MOFs, metal-substituted compounds based on M-DOBDC and M-HKUST-1 have demonstrated amongst the highest CO2 capacities at the low pressures typical of flue gasses. Here we(More)
Femtosecond two-color pump-probe experiments in the mid-infrared are performed on intersubband transitions in GaN=Al0:8Ga0:2N heterostructure. In these experiments, we observe around zero time delay distinct phonon sidebands, whic disappear because of spectral diffusion with a time constant of 80 fs. The signal itself decays with a time constant of 380 fs.(More)
The accuracy of five recently proposed van der Waals (vdW) density functionals (optB86b, optB88, optPBE, revPBE, and rPW86), the semiempirical vdW method of Grimme (DFT-D2), and conventional local (LDA) and gradient-corrected (GGA-PBE) density functionals are assessed with respect to experimental enthalpies (ΔH) for CO2 adsorption in four prototypical metal(More)
