Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Meromorphic p-valent Functions With Fixed Second Coefficients [PDF]

, 2016
In this paper we introduce the class L* of meromorphic p-valent functionswith fixed second coefficients estimates. Convex linear combinations, some distortion theoremsand radii of starlikeness and convexity for are presented in this paper for f(z) in ...

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Coefficient bounds for \(p\)-valent functions

Open Journal of Mathematical Analysis, 2023
This present paper introduces two new subclasses of p-valent functions. The coefficient bounds and Fekete-Szego inequalities for the functions in these classes are also obtained.

A GENERALIZATION OF REGULAR p-VALENT FUNCTIONS

, 1995
In this thesis we study p-valent annular starlike functions, p-valent convex functions and extend them to p-valent weakly star- like functions, p-valent weakly convex functions, respectively.

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 ...

On coefficients of some p-valent starlike functions

Filomat, 2019
We consider the class Ap of functions f analytic in the unit disk |z| < 1 in the complex plane, of the form f(z) = zp + ... such that Rezf(p)(z)/f (p-1)(z) > 0 in the unit disc. The object of the present paper is to derive some bounds for coefficients in this class and relation with the functions satisfying condition Ref(k)(z)/f(p-k ...

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

Advanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...
