Numerical Simulation of the Nonlinear Flow Properties in Self-Affine Aperture-Based Fractures
Advances in Civil Engineering, 2021 In order to study the effect of fracture geometry on the nonlinear flow properties in aperture-based fractures, a fractal model based on the self-affinity is proposed to characterize the three-dimensional geometry of rough-walled fractures.

Estimating the Permeability of Carbonate Rocks from the Fractal Properties of Moldic Pores using the Kozeny-Carman Equation [PDF]
Research Ideas and Outcomes, 2018 Reservoir modeling of carbonate rocks requires a proper understanding of the pore space distribution and its relationship to permeability. Using a pigeonhole fractal model we characterize the fractal geometry of moldic pore spaces and extract the fractal

Flat bands in fractal-like geometry [PDF]
, 2017 We report the presence of multiple flat bands in a class of two-dimensional lattices formed by Sierpinski gasket (SPG) fractal geometries as the basic unit cells. Solving the tight-binding Hamiltonian for such lattices with different generations of a SPG

On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions
Advanced Materials, EarlyView.We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.

An Interface Design for Calculation of Fractal Dimension
Chaos Theory and Applications, 2020 Partially insufficient is the modelling of irregular and complex forms using Euclidean geometry. On the other hand, fractal geometry allows irregular complex forms and structures to be expressed in mathematical terms. While fractal geometry appears to be

Design of Microstrip Antenna Using Fractal Geometry and Metamaterial
Diyala Journal of Engineering Sciences, 2015 The performance improvement which was achieved in rectangular patch antenna was made by the use of fractal geometry and Left-Handed Metamaterial (LHM). The two types of fractal geometry used are 1st iteration of Minkoweski and Koch separately, while the
