Fractional vs. Ordinary Control Systems: What Does the Fractional Derivative Provide?

Mathematics, 2022
The concept of a fractional derivative is not at all intuitive, starting with not having a clear geometrical interpretation. Many different definitions have appeared, to the point that the need for order has arisen in the field.

Large-Area MoS₂ Films Grown on Sapphire and GaN Substrates by Pulsed Laser Deposition

Nanomaterials, 2023
In this paper, we present the preparation of few-layer MoS2 films on single-crystal sapphire, as well as on heteroepitaxial GaN templates on sapphire substrates, using the pulsed laser deposition (PLD) technique.

Fluorographynes: Stability, Structural and Electronic Properties

, 2012
The presence in the graphyne sheets of a variable amount of sp2/sp1 atoms, which can be transformed into sp3-like atoms by covalent binding with one or two fluorine atoms, respectively, allows one to assume the formation of fulorinated graphynes ...
