Supercompliant Lattice Boosts n‐type AgSbTe2 Thermoelectrics
Advanced Functional Materials, EarlyView.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 ...

Certain Inequalities for a General Class of Analytic and Bi-univalent Functions [PDF]
Sahand Communications in Mathematical Analysis, 2019 In this work, the subclass of the function class S of analytic and bi-univalent functions is defined and studied in the open unit disc. Estimates for initial coefficients of Taylor- Maclaurin series of bi-univalent functions belonging these class are ...

Initial successive coefficients for certain classes of univalent functions [PDF]
arXiv, 2021 We consider a family of all analytic and univalent functions in the unit disk of the form $f(z)=z+a_2z^2+a_3z^3+\cdots$. The aim of this article is to investigate the bounds of the difference of moduli of initial successive coefficients, i.e. $\big | |a_{n+1}|-|a_n|\big |$ for $n=1,\,2$ and for some subclasses of analytic univalent functions.

Univalence criterion for meromorphic functions and Loewner chains [PDF]
Applied Mathematics and Computation, 218, (2011), 751-755, 2011 The object of the present paper is to obtain a more general condition for univalence of meromorphic functions in the U*. The significant relationships and relevance with other results are also given. A number of known univalent conditions would follow upon specializing the parameters involved in our main results.

A new Steiner symmetrization defined by a subclass of analytic function in a complex domain
Frontiers in Applied Mathematics and StatisticsIn this effort, we present a new definition of the Steiner symmetrization by using special analytic functions in a complex domain (the open unit disk) with respect to the origin.
