Density-functional Study of Small Molecules within the Krieger-Li-Iafrate Approximation [PDF]

, 1999
We report density-functional studies of several small molecules ($H_{2}, N_{2}, CO, H_{2}O$, and $CH_{4}$) within the Krieger-Li-Iafrate (KLI) approximation to the exact Kohn-Sham local exchange potential, using a three-dimensional real-space finite ...

Light‐Gated Thermal Domains in Nano‐Lanterns: Confined Heat Hotspots Sparks Electron Localization for Water Purification

Advanced Science, Volume 13, Issue 3, 14 January 2026.
A pore heat‐confined hollow porous canbon nanosphere catalyst is synthesized, with superior photo‐induced heat/redox response, revolutionizing peroxyacetic acid (PAA) activation for sustainable water purification. It overcomes traditional thermal PAA oxidation's energy inefficiency, enabling rapid pollutant degradation with a rate constant 11 times ...

Optimized Effective Potential Model for the Double Perovskites Sr2-xYxVMoO6 and Sr2-xYxVTcO6

, 2011
In attempt to explore half-metallic properties of the double perovskites Sr2-xYxVMoO6 and Sr2-xYxVTcO6, we construct an effective low-energy model, which describes the behavior of the t2g-states of these compounds.

Orbital Dependent Exchange-Only Methods for Periodic Systems

, 1999
Various orbital-dependent exchange-only potentials are studied which exhibit correct long-range asymptotic behaviour. We present the first application of these potentials for polymers and by one of these potentials for molecules.

Rigorous formulation of two-parameter double-hybrid density-functionals

, 2011
A two-parameter extension of the density-scaled double hybrid approach of Sharkas et al. [J. Chem. Phys. 134, 064113 (2011)] is presented. It is based on the explicit treatment of a fraction of multideterminantal exact exchange.
