Generation of fractal curves using new binary 8-point interpolatory subdivision scheme

Applied Mathematics in Science and Engineering
The subdivision scheme is a valuable tool for designing shapes and representing geometry in computer-aided geometric design. It has excellent geometric properties, such as fractals and adjustable shape.

The study of fractals among ecologists=O estudo dos fractais entre os ecólogos [PDF]

Acta Scientiarum: Biological Sciences, 2012
Fractals seemed to have permeated most scientific fields, including ecology. In fact, biodiversity and ecological processes are affected by spatial complexity, and fractals can help understand patterns at multiple scales.

Entanglement fractalization

Physical Review Research
We numerically explore the interplay of fractal geometry and quantum entanglement by analyzing the von Neumann entropy (known as entanglement entropy) and the entanglement contour in the scaling limit. Adopting quadratic fermionic models on Sierpinski carpet, we uncover intriguing findings.

Modeling of Color and Degradation of C‐Phycocyanin Extracted From Arthrospira platensis and Chlorogloeopsis HTF

Chemie Ingenieur Technik, EarlyView.
A nonlinear kinetic model was developed and successfully implemented, which describes the degradation of the protein C‐phycocyanin depending on temperature and pH value. C‐phycocyanin had been extracted from two different cyanobacteria. In addition to protein degradation, the fading of the typical blue color of this protein was included in the model ...

Hybrid Picard S-iteration for escape analysis, symmetry, computational insights, and visualization of complex fractals

Mathematical and Computer Modelling of Dynamical Systems
For the visualization of fractals, iterative schemes are fundamental and serve as important tools. In this paper, we introduce an escape criterion using the Hybrid Picard S-iteration to visualize fractals for the function [Formula: see text], where ...

An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading

Chemie Ingenieur Technik, EarlyView.
A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Resource‐Efficient Electrodes with Metallized Woven‐Glass‐Grid Current Collectors for Lithium‐Ion Batteries

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The use of metallized glass‐based woven‐grids instead of metal foils as current collectors for LIBs leads to a significant reduction in metal usage by over 90 % and weight savings of more than 80 %, resulting in an 11 % increase in specific energy at the cell level. Abstract A novel class of resource‐efficient, woven‐glass‐grid current collectors (CCs)
