TLDR
In this paper, a modified basis set of supplementary diffuse s and p functions, multiple polarization functions (double and triple sets of d functions), and higher angular momentum polarization functions were defined for use with the 6.31G and 6.311G basis sets.
Abstract
Standard sets of supplementary diffuse s and p functions, multiple polarization functions (double and triple sets of d functions), and higher angular momentum polarization functions (f functions) are defined for use with the 6‐31G and 6‐311G basis sets. Preliminary applications of the modified basis sets to the calculation of the bond energy and hydrogenation energy of N2 illustrate that these functions can be very important in the accurate computation of reaction energies.

Comparative analysis of the performance of commonly available density functionals in the determination of geometrical parameters for zinc complexes.

TL;DR: The results show that the use of effective‐core potentials has a limited impact, in terms of the accuracy in the determination of metal‐ligand bond‐lengths and angles in the dataset of copper complexes, and suggest that Double‐Hybrid and Long‐range Correction and Generalized Gradient Approximation methods could become a good alternative for the geometrical description of these systems.

Mesostructured Arrays of Nanometer-spaced Gold Nanoparticles for Ultrahigh Number Density of SERS Hot Spots

TL;DR: In this paper, a mesostructured polyoxometalate (POM)-silicatropic template (PSS) is first self-assembled at the air-water interface; upon UV irradiation, anion exchange cycles enable the free-floating PSS film to continuously uptake gold precursors from the solution subphase for diffusion-controlled and POM-site-directed photoreduction inside the silica channels.
