Mechanistic Insights and Performance Advancements in Flow Capacitive Deionisation for Sustainable Energy Conversion

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT Flow capacitive deionisation is an advanced electrochemical technology for water purification and energy‐related applications. It represents a viable alternative to conventional desalination methods due to its low operating voltage, continuous electrode regeneration, and stable performance under moderate‐to‐high salinity conditions. The use of

Coefficient problem for certain subclasses of bi-univalent functions defined by convolution [PDF]

Mathematica Moravica, 2016
In this paper, we consider a general subclass HλΣ (h, β) of bi-univalent functions. Bounds on the first two coefficients اa2ا and اa3ا for functions in HλΣ (h, β) are given. The main results generalize and improve a recent one obtained by Srivastava [18].

On Coefficient problem for bi-univalent analytic functions

, 2017
Estimates for initial coefficients of Taylor-Maclaurin series of bi-univalent functions belonging to certain classes defined by subordination are obtained. Our estimates improve upon the earlier known estimates for second and third coefficient. The bound for the fourth coefficient is new.

Electrostatic and Structural Engineering in Preintercalated V2O5: A Design Framework for Multivalent Ion Storage

Small Science, Volume 6, Issue 8, August 2026.
Preintercalation is presented as a coupled structural–electrostatic strategy for regulating ion storage in layered V2O5 cathodes. Interlayer spacing, guest‐ion charge density, structural water, migration barriers, and electronic structure are integrated into a unified design framework that clarifies how preintercalated species stabilize the lattice ...

$q$--Rabotnov Functions and Bi-univalent Functions

European Journal of Pure and Applied Mathematics
In this work, we introduce and investigate a new subclass of bi-univalent functions, denoted by $\mathfrak{R}_{\Sigma}^{\mu,x}(\varrho,\varphi,\lambda;\gamma;q)$, which is defined through the interplay between $q$--Rabotnov functions and $q$--Gegenbauer polynomials.

Specific whole‐chromosome identification of the A01/C1 homoeologs through oligonucleotide‐based chromosome painting in Brassica species

The Plant Journal, Volume 127, Issue 3, August 2026.
Significance Statement The Brassica genus contains many closely related, agronomically important crops with different combinations of the A, B, and C subgenomes. Here, we provide oligo‐painting probe sets capable of identifying subgenome‐specific chromosome pairs.

Gegenbauer Polynomials for a Subfamily of Bi-univalent Functions

Earthline Journal of Mathematical Sciences
We study a subfamily of bi-univalent and regular functions in the open unit disk subordinate to Gegenbauer polynomials. For functions in the defined subfamily, we derive initial coefficients bounds. Additionally, the Fekete-Szegö problem is handled for the elements of the defined subfamily.

Bi-Univalent Function Classes Defined by Imaginary Error Function and Bernoulli Polynomials

Axioms
In recent years, special functions have played a significant role in the investigation of different subclasses within the class of bi-univalent functions. In this work, we present and investigate two new subclasses of bi-univalent functions defined in U={
