Initial Coefficient Estimates for Bi-Univalent Functions Related to Generalized Telephone Numbers
Journal of MathematicsThis study defines three novel classes of bi-univalent functions connected to generalized telephone numbers for the first time. We produced assessments about the Taylor–Maclaurin coefficients a2 and a3 and Fekete–Szegö functional problems for functions ...

AN EXTREMAL PROBLEM FOR UNIVALENT FUNCTIONS [PDF]
Analele Universităţii Constantin Brâncuşi din Târgu Jiu : Seria Economie, 2010 Let S be the class of functions f(z)=z+a2z 2 …, f(0)=0, f′(0)=1 which are regular and univalent in the unit disk |z| x the equation φ′( x)=0 does not have real roots. Since S is a compact class, there exists x .

Using Synthetic Glycans to Investigate Anti‐Glycan Antibodies and Explore Their Medical Potential
Angewandte Chemie International Edition, EarlyView.Anti‐glycan antibodies are essential in health and disease. Access to novel glycan structures paves the way for progress in antibody profiling for biomarker discovery, antibody development, and vaccine design. We summarize the strategies to synthesize and utilize synthetic glycans for the development and application of anti‐glycan antibodies in basic ...

Numerical Simulation of Electrodialysis Desalination for Multicomponent Salt Lake Brine
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Electrodialysis (ED) technology is presently recognized as an effective approach for extracting lithium from salt lake brine. This study concentrates on modeling the ED desalination process applied to multicomponent salt lake brine and equivalent NaCl solutions.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...
