We report ab initio molecular dynamic simulations of the organic structure-directing agent (OSDA) in the channels of SCM-14 and SCM-15 germanosilicates for models with different germanium distribution. Since OSDA was free to move inside the channels,

The report looks at the development of the official Bulgarian holiday calendar and especially during the years of state socialism. The analysis shows that military victories are not the primary motive in choosing official memorial days. Even the Bulg

We used computational modeling, based on Density Functional Theory, to help understand the preference for the formation of silanol nests and the substitution of Si by Ti or Al in different crystallographic positions of the MSE-type framework. All the

According to periodic DFT calculations suggest that: Ge atoms in SCM-14 germanosilicate are clustered forming D4Rs populated entirely by Ge; structures with more Ge–O–Ge bridges are more stable; simulated 19F NMR chemical shifts do not correlated
