High‐Efficiency Quantum Defect Generation in Carbon Nanotubes via Oxygen‐Free Photochemistry

Advanced Functional Materials, EarlyView.
We show that oxygen plays an important role in quantum defect formation in carbon nanotubes and identify reaction conditions to create a range of different quantum defects for photonics and biosensing. ABSTRACT Single‐walled carbon nanotubes (SWCNTs) offer potential for a wide range of applications from optoelectronic devices to biomedical diagnostics.

Generalized Logistic Maps in the Complex Plane: Structure, Symmetry, and Escape-Time Dynamics

Axioms
In this paper, we introduce a generalised formulation of the logistic map extended to the complex plane and correspondingly redefine the classical Mandelbrot and Julia sets within this broader framework.

New Fixed Point Results for Fractal Generation in Jungck Noor Orbit with s-Convexity

Journal of Function Spaces, 2015
We establish new fixed point results in the generation of fractals (Julia sets, Mandelbrot sets, and Tricorns and Multicorns for linear or nonlinear dynamics) by using Jungck Noor iteration with s-convexity.

Comparative Study of Some Fixed-Point Methods in the Generation of Julia and Mandelbrot Sets

Journal of Mathematics, 2020
Fractal is a geometrical shape with property that each point of the shape represents the whole. Having this property, fractals procured the attention in computer graphics, engineering, biology, mathematics, physics, art, and design.

Julia and Mandelbrot Sets of Transcendental Function via Fibonacci-Mann Iteration

Journal of Function Spaces, 2022
In this paper, utilizing the Fibonacci-Mann iteration process, we explore Julia and Mandelbrot sets by establishing the escape criteria of a transcendental function, sinzn+az+c, n≥2; here, z is a complex variable, and a and c are complex numbers.

The Role of Viscoelasticity in Heterogeneous Glioblastoma Stem Cell Invasion in Biomimetic 3‐Dimensional Hydrogels

Advanced Healthcare Materials, EarlyView.
The role of viscoelasticity in the invasion of heterogeneous glioblastoma stem cells (GSCs) was investigated with GSCs categorized into subgroups based on molecular profile, as Reactive, Invasive, or Constructive using viscoelastic biomimetic hyaluronan‐oxime hydrogels.

Anti‐Inflammatory and Neuroactive Effects of Polymer‐Coated Iron Oxide Nanoparticles Functionalized With Interleukin 4 for Spinal Cord Injury

Advanced Healthcare Materials, EarlyView.
Polymer‐coated IONPs functionalized with IL‐4 display respective neuroactive and anti‐inflammatory actions on neural progenitor cells and macrophages/microglia in vitro. When examined chronically in a rat experimental model of spinal cord injury, rGO scaffolds carrying these nanosystems adequately integrate into the lesion, significantly reduce ...

Bioprinted Stiffness‑Tunable Pancreatic Microniches to Decode Early Tumor Initiation Mechanisms

Advanced Healthcare Materials, EarlyView.
Stiffness‐tunable GelMA microniches generated by microvalve bioprinting preserve wild‐type acinar identity while revealing a nonlinear, Kras‐dependent response to matrix mechanics. Intermediate stiffness promotes acinar‐to‐ductal metaplasia and proliferation, defining a permissive mechanical window.

Quaternion Feistel Cipher with an Infinite Key Space Based on Quaternion Julia Sets

Journal of Telecommunications and Information Technology, 2015
In this paper Quaternion Feistel Cipher (QFC) with an infinite key space based on quaternion Julia sets is proposed. The basic structure of the algorithm is based on the scheme proposed in 2012 by Sastry and Kumar.
