Second Hankel determinant for a certain function class of bi-univalent functions associated with Salagean derivative operator

European Journal of Mathematics and Applications, 2023
In this work, we investigate the bounds on the fourth initial coefficient $|a_4|$ and the second Hankel determinant $|a_2a_4 - a^ 2_3|$ for a class of analytic and bi-univalent functions defined in the open unit disk.

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

Small, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Proteomic Analysis Reveals Accompanying Anion‐Dependent Changes of Cadmium Toxicity During Arabidopsis thaliana Development

Plant, Cell &Environment, EarlyView.
ABSTRACT Cadmium (Cd) is a significant environmental pollutant with widespread detrimental effects on living organisms, making it a frequent subject of laboratory studies. However, different types of Cd salts are used to spike media, often without considering the possibility that accompanying anions may influence the effects of metal cations. Using two

Subclasses of Bi-Univalent Functions of Complex Order Based on Subordination Conditions Involving Wright Hypergeometric Functions

Journal of Mathematical and Fundamental Sciences, 2015
In this paper, we introduce and investigate a new subclass of bi-univalent functions Σ of complex order dened in the open unit disk, which are associated with hypergeometric functions and satisfying subordinate conditions. Furthermore, we nd estimates on

Tailoring the Crystallization Behavior of Mixed Lead‐Tin Mixed‐Halide Perovskites for Optimal‐Bandgap Solar Cells

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Carefully tuning the composition of mixed lead‐tin mixed iodide‐bromide perovskites results in an optimal‐bandgap semiconductor for solar energy conversion. Homogenous crystallization of this perovskite involves a short time delay between deposition of the precursor solution and applying an antisolvent. Using a bulk additive and top surface passivation

Bi-Bazilevič functions of complex order involving Ruscheweyh type q-difference operator

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2018
In this paper, we define a new subclass of bi-univalent functions involving q-difference operator in the open unit disk. For functions belonging to this class, we obtain estimates on the first two Taylor-Maclaurin coefficients |a2| and |a3|.

Sakaguchi type functions defined by balancing polynomials [PDF]

Mathematica Bohemica
The class of Sakaguchi type functions defined by balancing polynomials has been introduced as a novel subclass of bi-univalent functions. The bounds for the Fekete-Szegö inequality and the initial coefficients $\vert a_2\vert$ and $\vert a_3\vert$ have ...
