Spinel nitride solid solutions: charting properties in the configurational space with explainable machine learning
Pablo Sánchez-Palencia, Said Hamad, Pablo Palacios +2
Ab initio prediction of the variation of properties in the configurational space of solid solutions is computationally very demanding. We present an approach to accelerate these pr…
Engineering the electronic and optical properties of 2D porphyrin paddlewheel metal-organic frameworks
Victor Posligua, Dimpy Pandya, Alex Aziz +4
Metal organic frameworks (MOFs) are promising photocatalytic materials due to their high surface area and tuneability of their electronic structure. We discuss here how to engineer…
The Si-Ge substitutional series in the chiral STW Zeolite Structure Type
Reus Tiago Rigo, Salvador Rodríguez-Gómez Balestra, Said Hamad +4
The whole compositional range (Ge = Ge/(Ge+Si)= 0 to 1) of zeolite STW has been synthesized and studied by a comprehensive combined experimental--theoretical approach. The yiel…
Atomic charges for modeling metal-organic frameworks: Why and how
Said Hamad, Salvador R. G. Balestra, Rocio Bueno-Perez +2
Atomic partial charges are parameters of key importance in the simulation of Metal-Organic Frameworks (MOFs), since Coulombic interactions decrease with the distance more slowly th…
Understanding Nanopore Window Distortions in the Reversible Molecular Valve Zeolite RHO
Salvador Rodríguez-Gómez Balestra, Said Hamad, A. Rabdel Ruiz-Salvador +4
Molecular valves are becoming popular for potential biomedical applications. However, little is known concerning their performance in energy and environmental areas. Zeolite RHO sh…
The symmetry-adapted configurational ensemble approach to the computer simulation of site-disordered solids
Ricardo Grau-Crespo, Said Hamad
Site-occupancy disorder, defined as the non-periodic occupation of lattice sites in a crystal structure, is a ubiquitous phenomenon in solid-state physics and chemistry. Examples a…
