User's talk

In 2022, IT4Innovations was forced to temporarily turn off operated HPC systems because electricity prices increased enormously. Since then, the price has stayed high, and to avoid a potential next outage due to budget shortage, we investigated possible improvements to the Karolina system's energy efficiency. The behavior of accommodated CPUs and GPUs when executing workloads of a wide range...

User's talk

Heterostructured two-dimensional (2D) material, particularly van der Waals heterostructures (vdW)[1], are promising photocatalysts because of their adjustable optoelectronic properties such as efficient carrier separation[2] and type-II band alignment[3]. The layers of vdW heterostructures are assembled in a highly regulated sequence thus providing a platform for creating novel materials and...

138. Employing supercomputers to determine the local structure of framework and extra-framework species and to subsequently evaluate their NMR parameters for comparison with experiments

User's talk

Zeolites are crystalline microporous aluminosilicates widely used as molecular sieves and catalysts in industrial chemical processes. Extra–framework cations compensate the negative charge of the microporous aluminosilicate frameworks [Sin-mAlmO2n]m- made of corner–sharing TO4 tetrahedra (T = Si, Al-). Furthermore, also electron-pair acceptor Al framework Lewis sites are often present in...
