Review of Silicon Reactivity of Self-assembled monolayer and its Properties
Abstract: In most cases, the assumption of perfect high viscosity between silicon and silver underlies the modelization of silicene on Ag(111). According to recent reports, growth does not take place on top of the Ag(111) terraces, but rather within the first layer of them. In this article, we present the results of a study that combines scanning tunnelling microscopy and density functional theory to simulate the nucleation process and reveal the …

Peri-implant Inflammation Defined by the Implant–Abutment Interface
Abstract: An interface of implant-abutment at the alveolar bone crest is allied with sustained peri-implant inflammation; though, whether extent of inflammation is correspondingly reliant on interface position remains unknown. This study compared the distribution and density of inflammatory cells surrounding implants with a supracrestal, crestal, or subcrestal implant-abutment interface. All implants established a parallel pattern of peri-implant inflammation: neutrophilic polymorphonuclear leukocytes (neutrophils) extremely collected at or proximately coronal to the interface. …
