Synthesis of Telechelic‐Type Polypeptides Functionalized with Aromatic Units and the Characterization of Their Structures and Thermal Properties

open access: yesMacromolecular Rapid Communications, EarlyView.
Polypeptide chains were extended from both ends of aromatic diamines by chemoenzymatic polymerization, resulting in the synthesis of telechelic polyglycines (TPG) and polyalanines (TPA). These telechelic polymers assembled into branched nanofibrils through π‐π stacking of aromatic rings, with the polymer backbones bent at the aromatic unit.

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities

open access: yesJournal of Interior Design, EarlyView., 2022
ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.

Non-linearity of the dynamics of transcendental function using Fibonacci–Mann iteration and some critical remarks

open access: yesAlexandria Engineering Journal
With a generalized setting of transcendental functions associated with a non-linear variable, we have observed the combinatorial structures of the fractals of Julia sets and Mandelbrot sets due to the function zκcos(zκ)+pz2+q, in the complex plane with p,

Effect of Magnetic Field and Temperature on the Excess Minority Carrier Density in the Base of a Radial Junction Solar Cell

open access: yesNano Select, EarlyView.
This study explores how magnetic field and temperature influence excess minority carrier density in a radial‐junction silicon solar cell. Using an analytical model based on Bessel functions, key trends are revealed, including thermal insensitivity in a specific magnetic field range.

A Novel Method for Image Encryption Based on Chaos and Transcendental Numbers

open access: yesIEEE Access, 2019
In this paper, a method for image encryption is proposed based on a novel approach using chaos and transcendental numbers for generating the substitution box and the ciphering keys. The Chaotic Pi Ciphering (CPC) is a robust symmetric cryptosystem of the

Fiber Processing of Recombinant Spider Silk Proteins

open access: yesJournal of Polymer Science, EarlyView.
Recombinant spider silk proteins are produced using biotechnological tools to mimic the properties of natural ones. Modern spinning techniques replicating the natural spinning process can produce biomimetic fibers. Additionally, nonnatural spinning techniques can create fibers in the submicron range, broadening the range of applications.
