Convolution Properties of Meromorphic P-Valent Functions with Coefficients of Alternating Type Defined Using q-Difference Operator

Mathematics
Certain characteristics of univalent functions with negative coefficients of the form f(z)=z−∑n=1∞a2nz2n,a2n>0 have been studied by Silverman and Berman.

Notes on p-valently Bazilević functions

Applied Mathematics Letters, 1991
Let \({\mathcal A}_ p\) be the family of functions f of the form \(f(z)=z^ p+a_{p+1}z^{p+1}+...\), (p\(\in \{1,2,...\})\), that are analytic in the unit disc \(\Delta =\{z:| z| \beta,\quad z\in \Delta \}, \] \[ {\mathcal C}_ p(\alpha,\beta)=\{f\in {\mathcal A}_ p:\;Re J(f(z);\alpha)0\), \(0\leq -\beta /\alpha \leq 1/2\) (or \(f\in {\mathcal C}_ p ...

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Differential sandwich theorems of p−valent analytic functions involving a linear operator

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013
In this paper we derive some subordination and superordination results for certain p-valent analytic functions in the open unit disc, which are acted upon by a class of a linear operator.

Post-Wick theorems for symbolic manipulation of second-quantized expressions in atomic many-body perturbation theory [PDF]

, 2009
Manipulating expressions in many-body perturbation theory becomes unwieldily with increasing order of the perturbation theory. Here I derive a set of theorems for efficient simplification of such expressions.

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

Advanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...

Plancherel-Rotach asymptotic expansion for some polynomials from indeterminate moment problems

, 2013
We study the Plancherel--Rotach asymptotics of four families of orthogonal polynomials, the Chen--Ismail polynomials, the Berg-Letessier-Valent polynomials, the Conrad--Flajolet polynomials I and II.

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

Advanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).
