Coefficient Bounds for a Subclass of Bi-Univalent Functions

CAUCHY: Jurnal Matematika Murni dan Aplikasi
In this paper, we obtain explicit upper bounds for the initial seven coefficients and their inverses for a subclass of bi-univalent functions defined via subordination. Using coefficient estimates associated with the Carathodory class and coefficient comparison techniques, expressions for the bounds of a2, a3, , a7 are derived.

Coefficient Estimates for Bi-Univalent Bazilevic Functions

Analysis in Theory and Applications, 2014
In this paper we consider the class of Bazilevic functions for bi-univalent functions. For this we will estimate the coefficients $a_2$ and $a_3$ using Caratheodory functions and the method of differential subordination.

The Evolution of Metal Halide Perovskite Transistors

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Metal halide perovskites (MHPs) offer a revolutionary pathway for next‐generation field‐effect transistors (FETs) because of their exceptional carrier mobilities and cost‐effective processability. However, their transition to practical electronics is significantly challenged by intrinsic instability and imbalanced charge transport. This review

Estimates for the Initial Coefficients of Bi-univalent Functions

, 2012
A bi-univalent function is a univalent function defined on the unit disk with its inverse also univalent on the unit disk. Estimates for the initial coefficients are obtained for bi-univalent functions belonging to certain classes defined by subordination and relevant connections with earlier results are pointed out.

Machine‐Learning‐Assisted Discovery and Accelerated Synthesis of Metal Phosphosulfides

Small, Volume 22, Issue 52, 16 September 2026.
The synthesizability and band gaps of 909 hypothetical ternary phosphosulfides are evaluated by a combination of density functional theory and multi‐fidelity machine learning. The accelerated material development workflow is extended to the experimental domain by demonstrating a route to high‐throughput synthesis and characterization of virtually any ...

Synthesis and Crystal Structure of Sb2O2[CO3] with Stereochemically Active Lone Electron Pairs at Elevated Pressures

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 13, 1 September 2026.
Sb2O2[CO3] was synthesized at 20 GPa in a laser‐heated diamond cell and is an antimony oxocarbonate with stereochemically active lone electron pairs on the antimony atoms. Its crystal structure is characterized by the presence of [CO3]2–‐groups and by interconnected “Sb2O5‐units” which form a Sb–O‐network within the b,c lattice plane.
