Sodium‐Manganese Oxides in Faradaic Desalination: Achieving Long‐Cycling Stability Through Morphological and Structural Optimization

ENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 5, September 2025.
The performance of sodium‐manganese oxides (NMOs) as electrode materials for faradaic deionization is explored to address the challenges of water desalination. By investigating the impact of their morphology and crystal structure, a mixed‐phase NMO demonstrates enhanced salt removal capacity and long‐term stability over 870 cycles, highlighting its ...

On a Certain Class of Bi-Univalent Functions in Connection with Gegenbauer Polynomials

Pan-American Journal of Mathematics
Recent direction of studies shows that there is a kin connection between regular functions and orthogonal polynomials. In this paper, we study a new class of regular and bi-univalent functions that involve the familiar Gegenbauer polynomials.

Supercompliant Lattice Boosts n‐type AgSbTe2 Thermoelectrics

Advanced Functional Materials, Volume 35, Issue 31, August 1, 2025.
The supercompliant lattice design enables the first realization of n‐type electrical transport in AgSbTe2 by overcoming intrinsic electron‐killer defects and exceeding the doping limits imposed by the conventional Hume–Rothery rule. Accordingly, the best performance n‐type Ag0.8Na0.3Sb0.6Bi0.4Te2 sample achieves a low κ of 0.27 W·m−1·K−1 that ...

Applications of (M,N)-Lucas Polynomials for a Certain Family of Bi-Univalent Functions Associating λ-Pseudo-Starlike Functions with Sakaguchi Type Functions

Earthline Journal of Mathematical Sciences
In this article, we use the (M,N)-Lucas Polynomials to determinate upper bounds for the Taylor-Maclaurin coefficients $\left|a_{2}\right|$ and $\left| a_{3}\right|$ for functions belongs to a certain family of holomorphic and bi-univalent functions ...

Coefficient bounds for certain classes of bi-univalent functions

Hacettepe Journal of Mathematics and Statistics, 2015
In this paper, we introduce two new subclasses of the function class Σ of bi-univalent functions defined in the open unit disk. Furthermore, we find estimates on the coefficients |a2| and |a3| for functions in these new subclasses.

Cs2AgBiBr6 Perovskites: Designing Stable, Sensitive and Selective Eco‐friendly Ozone Sensors

Advanced Sensor Research, Volume 4, Issue 8, August 2025.
An eco‐friendly ozone (O3) sensor made from lead‐free Cs2AgBiBr6 double perovskite is presented. It operates efficiently at room temperature with low energy consumption, overcoming the limitations of traditional metal‐oxide‐based sensors. The optimized morphology design enhances ozone detection and demonstrates high selectivity for ozone over other ...
