Changing the composition and structure of a bimetallic surface system modifies its electronic properties and thus its catalytic activity. On the basis of density functional theory calculations, the electronic factors underlying the modified properties of bimetallic surfaces such as overlayer systems and, in particular, surface alloys will be discussed. It will be demonstrated that by mixing two...
Ferrihydrite nanoparticles with nominal sizes of 3 and 6 nm were assembled within ferritin, an iron storage protein. The crystallinity and structure of the nanoparticles (after removal of the protein shell) were evaluated by high-resolution transmission electron microscopy (HRTEM), atomic force microscopy (AFM), and scanning tunneling microscopy (STM). HRTEM showed that amorphous and crystallin...
This study employs a comprehensive computational analysis of the 2-benzyloxy-1,2,4-triazolo[1,5-a] quinazolin-5(4H)-one (ID code: CCDC 834498) to explore its intermolecular interactions, surface characteristics, and crystal structure. Utilizing Hirshfeld technique Crystal Explorer 17.5, maps surfaces for detailed understanding atom pair close contacts interaction types. The also investigates co...
Abstract Current reactive transport model (RTM) uses control as the sole arbiter of differences in reactivity. For simulation crystal dissolution, a constant reaction rate is assumed for entire surface function chemical parameters. However, multiple dissolution experiments confirmed existence an intrinsic variability rates, spanning two to three orders magnitude. Modeling this variance process ...
