Quasi-convex univalent functions

International Journal of Mathematics and Mathematical Sciences, 1980
In this paper, a new class of normalized univalent functions is introduced. The properties of this class and its relationship with some other subclasses of univalent functions are studied. The functions in this class are close-to-convex.

ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

Advanced Science, EarlyView.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

Salt Water Drops Slide Faster: Ionic Modulation of Drop Friction

Advanced Science, EarlyView.
Salt ions markedly accelerate water drops on conductive substrates coated with nanometer‐thin hydrophobic layers. Across diverse electrolytes and surfaces, higher ion concentration consistently lowers kinetic friction by reducing contact angle hysteresis.

On the properties of a class of polyharmonic functions

Mathematical Modelling and Analysis, 2013
The aim of this paper is to investigate some motivated geometrical aspects and properties of polyharmonic functions (PH) including starlikeness, convexity and univalence. A polyharmonicity preserving complex operator is also introduced.

Circular Potential of Lithium‐Ion Battery Recycling Slags: Quantifying Microstructure and Elemental Distribution for a Holistic Valorization

Advanced Science, EarlyView.
A lithium‐bearing slag is investigated with the goal of holistic valorization. The present β‐eucryptite (LiAlSiO4) exhibits a high lithium content and low levels of impurities. The spinel contains most of the chromium and vanadium, representing additional valorization opportunities.

An Application of Liouville–Caputo-Type Fractional Derivatives on Certain Subclasses of Bi-Univalent Functions

Fractal and Fractional
In this study, we present two novel subclasses of bi-univalent functions defined in the open unit disk, utilizing Liouville–Caputo fractional derivatives.

Reconstructed Polyamide Nanolayers via Two‐Stage Interfacial Polymerization Engineering for Precise Ion Sieving

Advanced Science, EarlyView.
A reconstructed polyamide nanofiltration membrane is engineered via a two‐stage interfacial polymerization strategy for lithium extraction from complex brines. Incorporated bidentate quaternary ammonium monomers enable synergistic steric and electrostatic effects within sub‐nanometer channels, achieving 60‐fold lithium enrichment and demonstrating ...

Inclusive Subfamilies of Complex Order Generated by Liouville–Caputo-Type Fractional Derivatives and Horadam Polynomials

Fractal and Fractional
In this paper, we introduce the inclusive subfamilies of complex order E(δ1,δ2,δ3,δ4,a,b) and C(δ1,δ2,δ3,δ4,a,b), defined by means of the Liouville–Caputo-type derivative operator and subordination to the Horadam polynomials.

Heterogeneity‐Guided Interlayer Tuning in Vermiculite‐MOF Membranes for Efficient Li+/Mg2+ Separation

Advanced Science, EarlyView.
Heterogeneity‐guided interlayer engineering is achieved by integrating porous MOF nanosheets into a 2D vermiculite laminate, reprogramming ion transport pathways. The resulting hybrid membranes combine sub‐nanoconfinement and charge heterogeneity, enabling accelerated Li+ transport and reinforced Mg2+ exclusion.
