Coefficient Estimates for Subclasses of Bi-Univalent Functions

Journal of Al-Qadisiyah for Computer Science and Mathematics, 2018
 In the present paper, we introduce two new subclasses of  the class consisting of analytic and bi-univalent functions in the open unit disk . Also, we obtain the estimates on the Taylor-Maclurin   coefficients and for functions in these subclasses. We obtain new special cases for our results.

Applications of the q-Srivastava-Attiya Operator Involving a Certain Family of Bi-Univalent Functions Associated with the Horadam Polynomials

Symmetry, 2021
In this article, by making use of the q-Srivastava-Attiya operator, we introduce and investigate a new family SWΣ(δ,γ,λ,s,t,q,r) of normalized holomorphic and bi-univalent functions in the open unit disk U, which are associated with the Bazilevič ...

Biopolymer Membranes for Osmotic Power Generation in Bionic Applications

Advanced Materials, EarlyView.
This review provides an overview of biopolymer‐based osmotic power generation for bionic applications. It uniquely bridges biopolymer membranes, reverse electrodialysis(RED), and bionic applications, addressing a critical research gap by integrating biopolymer membranes with RED technologies for biomedical use.

Subordination Properties of Bi-Univalent Functions Involving Horadam Polynomials

Journal of Function Spaces
In this research, we investigate a family of q-extensions defined on an open unit disk, which is based on bi-univalent functions associated with differential subordination.

On a New Class of Concave Bi-Univalent Functions Associated with Bounded Boundary Rotation

Mathematics
In this research article, we introduce a new subclass of concave bi-univalent functions associated with bounded boundary rotation defined on an open unit disk. For this new class, we make an attempt to find the first two initial coefficient bounds.

Fibonacci Numbers Related to Some Subclasses of Bi-Univalent Functions

International Journal of Mathematics and Mathematical Sciences
This research paper introduces the novel subclass of bi‐univalent functions that are connected to Fibonacci numbers. Our main contributions in this study involve establishing constraints on the absolute values of the second coefficient |a2| and the third

Chitosan, Gelatine, and Cellulose Based Hydrogels for the Removal of Potentially Toxic Elements from Aquaculture Water: A Comparative Study

Advanced Sustainable Systems, EarlyView.
Hydrogels made of chemically modified biopolymers are easy to prepare and cost‐effective, they have proven to be effective materials for the simultaneous removal of seven potentially toxic elements (PTEs) from ultrapure and real water samples. The cellulose‐based one seems the best for single treatments while the gelatine‐based one seems the most ...

Initial Coefficient Estimates for Bi-Univalent Functions Related to Generalized Telephone Numbers

Journal of Mathematics
This study defines three novel classes of bi-univalent functions connected to generalized telephone numbers for the first time. We produced assessments about the Taylor–Maclaurin coefficients a2 and a3 and Fekete–Szegö functional problems for functions ...

Fekete-Szegö Inequality for a Subclass of Bi-Univalent Functions Linked to q-Ultraspherical Polynomials

Contemporary Mathematics
In this study, we introduce a new class of bi-univalent functions using q-Ultraspherical polynomials. We derive the Fekete and Szegö functional problems for functions in this new subclass, as well as estimates for the Taylor-Maclaurin coefficients |α2 ...
